Skype () is a proprietary telecommunication application operated past Skype Technologies, a division of Microsoft, best known for VoIP-based videotelephony, videoconferencing and vox calls. It also has instant messaging, file transfer, debit-based calls to landline and mobile telephones (over traditional phone networks), and other features. Skype is available on various desktop, mobile, and video game console platforms.

Skype was created by Niklas Zennström, Janus Friis, and 4 Estonian developers and showtime released in August 2003. In September 2005, eBay acquired Skype for $ii.vi billion.[half dozen] In September 2009,[7] Argent Lake, Andreessen Horowitz, and the Canada Alimony Program Investment Board bought 65% of Skype for $1.nine billion from eBay, valuing the business organization at $two.92 billion. In May 2011, Microsoft bought Skype for $8.5 billion and used it to supervene upon their Windows Alive Messenger. As of 2011, most of the development squad and 44% of all the division'southward employees were in Tallinn and Tartu, Estonia.[8] [9] [10]

Skype originally featured a hybrid peer-to-peer and client–server system.[11] It became entirely powered by Microsoft-operated supernodes in May 2012;[12] in 2017, information technology inverse from a peer-to-peer service to a centralized Azure-based service.

As of March 2020, Skype was used by 100 meg people at least one time a month and by 40 one thousand thousand people each day.[13] During the COVID-19 pandemic, Skype lost a big office of its market share to Zoom.[14]

Etymology [edit]

The name for the software is derived from "Heaven peer-to-peer", which was then abbreviated to "Skyper". Even so, some of the domain names associated with "Skyper" were already taken.[15] Dropping the final "r" left the current title "Skype", for which domain names were available.[16]

History [edit]

Skype was founded in 2003 by Niklas Zennström, from Sweden, and Janus Friis, from Denmark.[17] The Skype software was created by Estonians Ahti Heinla, Priit Kasesalu, Jaan Tallinn, and Toivo Annus.[xviii] Friis and Annus are credited with the idea of reducing the toll of voice calls by using a P2P protocol similar that of Kazaa.[19] An early alpha version was created and tested in spring 2003, and the first public beta version was released on 29 August 2003.[20] [19]

In June 2005, Skype entered an agreement with the Polish web portal Onet.pl for an integrated offering on the Polish marketplace.[21] On 12 September 2005, eBay Inc. agreed to acquire Luxembourg-based Skype Technologies SA for approximately US$2.5 billion in up-front cash and eBay stock, plus potential performance-based consideration.[22] On 1 September 2009, eBay announced it was selling 65% of Skype to Silvery Lake, Andreessen Horowitz, and the Canada Alimony Plan Investment Board for US$1.nine billion, valuing Skype at US$two.75 billion.[23] On fourteen July 2011, Skype partnered with Comcast to bring its video chat service to Comcast subscribers via HDTV sets.[24]

On 17 June 2013, Skype released a free video messaging service, which tin can be operated on Windows, Mac Os, iOS, iPadOS, Android, and BlackBerry.[25]

Between 2017 and 2020, Skype collaborated with PayPal to provide a coin-send feature. It allowed users to transfer funds via the Skype mobile app in the centre of a chat.[26]

In 2019, Skype was announced to be the sixth most downloaded mobile app of the decade, from 2010 to 2019.[27]

Microsoft acquisition [edit]

On 10 May 2011, Microsoft Corporation caused Skype Communications, S.à r.50 for US$8.five billion.[28] The visitor was incorporated every bit a division of Microsoft, which acquired all its technologies with the buy. The acquisition was completed on xiii October 2011.[28] [29] Before long later on the acquisition, Microsoft began integrating the Skype service with its own products. Along with taking over the development of existing Skype desktop and mobile apps, the company adult a dedicated client app for its so-newly released, touch-focused Windows 8 and Windows RT operating systems. They were fabricated available from Windows Store when the then-new Bone launched on 26 October 2012. The following year, it became the default messaging app for Windows 8.ane, replacing the Windows eight Messaging app at the fourth dimension, and became pre-installed software on every device that came with or upgraded to viii.1.[xxx]

In a month-long transition from viii to 30 April 2013, Microsoft discontinued 2[run across talk] of its ain products in favor of Skype, including its Windows Live Messenger instant messaging service, although Messenger continued to be available in mainland Cathay.[31] [32]

On 11 November 2014, Microsoft appear that in 2015, its Lync product would be replaced by Skype for Business organisation. This combined features of Lync and the consumer Skype software. There are two user interfaces, organizations could switch their users between the default Skype for Business interface to the Lync interface.[33]

Post-acquisition [edit]

On 12 Baronial 2013, Skype released the iv.x update to the app for Apple iPhone and iPad that allows HD quality video for iPhone 5 and fourth-generation iPads.[34]

On 20 Nov 2014, Microsoft Office'due south team announced that a new conversation powered by Skype would be implemented in their software, giving tools to be able to chat with co-workers in the aforementioned certificate.[35]

On 15 September 2015, Skype announced the release of Mojis, "a brand new fashion to express yourself on Skype". Mojis are short clips/gifs featuring characters from films and Tv shows to be entered into conversations with the same ease every bit emoticons. They worked with Universal Studios, Disney Muppets, BBC and other studios to add to the available collection of Mojis.[36] Afterward that year, Gurdeep Singh Pall, Corporate Vice President of Skype, appear that Microsoft had acquired the technology from Talko.[37]

In July 2016, Skype introduced an early Alpha version of a new Skype for Linux client, built with WebRTC technology, later on several petitions had asked Microsoft to continue development for Linux.[38] [39] In September of that year, Skype updated their iOS app with new features, including an option to phone call contacts on Skype through Siri phonation commands.[40] In Oct of that year, Microsoft launched Skype for Concern for Mac.[41]

In February 2017, Microsoft announced plans to discontinue its Skype Wi-Fi service globally. The application was delisted, and the service itself became non-functional from 31 March 2017.[42] [43] On five June 2017, Microsoft announced its plans to revamp Skype with similar features to Snapchat, allowing users to share temporary copies of their photos and video files.[44] In late June 2017, Microsoft rolled out their latest update for iOS, incorporating a revamped design and new third-party integrations, with platforms including Gfycat, YouTube, and UpWorthy.[45] It was not well-received, with numerous negative reviews and complaints that the new client broke existing functionality.[46] Skype later removed this "makover". In December 2017, Microsoft added "Skype Interviews", a shared lawmaking editing organization for those wishing to agree job interviews for programming roles.[47] [48]

Microsoft eventually moved the service from a peer-to-peer to a central server based organization, and with it adjusted the user interfaces of apps to brand text-based messaging more prominent than voice calling. Skype for Windows,[49] iOS,[l] Android,[51] Mac[52] and Linux[53] all received meaning visual overhauls at this time.

Features [edit]

Registered users of Skype are identified by a unique Skype ID and may be listed in the Skype directory under a Skype username.[54] Skype allows these registered users to communicate through both instant messaging and voice conversation. Voice conversation allows telephone calls between pairs of users and briefing calling and uses proprietary sound codec. Skype's text chat client allows group chats, emoticons, storing chat history, and editing of previous messages. Offline messages were implemented in a beta build of version five but removed subsequently a few weeks without notification. The usual features familiar to instant messaging users—user profiles, online condition indicators, and and then on—are also included.

The Online Number, a.k.a. SkypeIn, service allows Skype users to receive calls on their computers dialed by conventional phone subscribers to a local Skype phone number; local numbers are bachelor for Australia, Belgium, Brazil, Chile, Republic of colombia, Denmark, the Dominican Republic, Republic of estonia, Finland, French republic, Germany, Hong Kong, Hungary, India, Ireland, Japan, United mexican states, Nepal, New Zealand, Poland, Romania, South Africa, South Korea, Sweden, Switzerland, Turkey, the Netherlands, the U.k., and the United states of america.[55] [56] A Skype user can have local numbers in any of these countries, with calls to the number charged at the aforementioned rate as calls to stock-still lines in the state.

Skype supports briefing calls, video chats, and screen sharing between 25 people at a time for costless,[57] which then increased to 50 on 5 April 2019.[58]

Skype does not provide the power to telephone call emergency numbers, such as 112 in Europe, 911 in North America, 999 in the United kingdom or 100 in India and Nepal.[59] Nonetheless, as of Dec 2012, there is limited back up for emergency calls in the United Kingdom, Australia, Kingdom of denmark, and Finland.[sixty] The U.Due south. Federal Communications Commission (FCC) has ruled that, for the purposes of section 255 of the Telecommunications Deed, Skype is not an "interconnected VoIP provider".[61] Every bit a consequence, the U.Due south. National Emergency Number Association recommends that all VoIP users have an analog line available as a fill-in.[62]

In 2019, Skype added an option to blur the groundwork in a video conversation interface using AI algorithms purely washed using software, despite a depth-sensing camera not being present in most webcams.[63]

At the stop of 2010, at that place were over 660 million worldwide users, with over 300 one thousand thousand estimated agile each month as of August 2015.[81] At one point in February 2012, there were 34 1000000 users concurrently online on Skype.[82]

In Jan 2011, after the release of video calling on the Skype client for iPhone, Skype reached a record 27 meg simultaneous online users.[83] This record was broken with 29 1000000 simultaneous online users on 21 February 2011[84] and again on 28 March 2011 with 30 million online users.[85] On 25 February 2012, Skype announced that it has over 32 one thousand thousand users for the first fourth dimension ever.[86] By 5 March 2012, it had 36 one thousand thousand simultaneous online users,[87] and less than a year later, on 21 January 2013, Skype had more than than l one thousand thousand concurrent users online.[88] In June 2012, Skype had surpassed seventy 1000000 downloads on Android.[89]

On 19 July 2012, Microsoft appear that Skype users had logged 115 billion minutes of calls in the quarter, up to 50% since the last quarter.[xc]

On fifteen Jan 2014, TeleGeography estimated that Skype-to-Skype international traffic has gone up to 36% in 2013 to 214 billion minutes.[91]

At end March 2020 there was a lxx% increase in the number of daily users from the previous month, due to the COVID-nineteen pandemic.[92]

System and software [edit]

Client applications and devices [edit]

Windows client [edit]

Skype 4.0 (released 2009)

Multiple different versions of Skype have been released for Windows since its conception. The original line of Skype applications connected from versions i.0 through 4.0. It has offered a desktop-only program since 2003. After, a mobile version was created for Windows Phones.

In 2012, Skype introduced a new version for Windows viii similar to the Windows Telephone version.[93] On 7 July 2015 Skype modified the application to direct Windows users to download the desktop version, just it was set up to go along working on Windows RT until October 2016.[94] In Nov 2015, Skype introduced 3 new applications, called Messaging, Skype Video, and Telephone, intended to provide an integrated Skype experience on Windows 10.[95] [96] On 24 March 2016, Skype announced the integrated applications did not satisfy nearly users' needs and appear that they and the desktop customer would eventually be replaced with a new UWP application,[97] which was released as a preview version for the Windows 10 Anniversary Update and dubbed as the stable version with the release of the Windows ten Creators Update.

The latest version of Skype for Windows is Skype 11, which is based on the Universal Windows Platform and runs on diverse Windows x-related systems, including Xbox One, Xbox Series X/Due south, Windows phones, and Microsoft Hololens. Microsoft nonetheless offers the older Skype viii, which is Win32-based and runs on all systems from Windows XP (which is otherwise unsupported past Microsoft) to the nigh recent release of Windows ten.[98]

In late 2017, this version was upgraded to Skype 12.nine in which several features were both removed and added.[99]

Other desktop clients [edit]

  • macOS (10.nine or newer)[98]
  • Linux (Debian, Debian-based (Ubuntu, etc.), Fedora, openSUSE)[98]

Mobile clients [edit]

  • iOS
  • Android

Skype was previously available on Nokia 10, Symbian, BlackBerry OS and BlackBerry 10 devices. In May 2009 a Version 3.0 was available on Windows Mobile 5 to 6.i, and in September 2015 a Version 2.29[100] was available on Windows Phone 8.1; in 2016 Microsoft announced that this would stop working in early 2017 once Skype's transition from peer-to-peer to customer-server was consummate.[101]

Other platforms [edit]

  • The Nokia N800, N810, and N900 Cyberspace tablets, which run Maemo
  • The Nokia N9, which runs MeeGo, comes with Skype voice calling and text messaging integrated; however, it lacks video-calling.
  • Both the Sony mylo COM-i and COM-ii models
  • The PlayStation Portable Slim and Light serial, though the user needs to purchase a particularly designed microphone peripheral. The PSP-3000 has a built-in microphone, which allows advice without the Skype peripheral.[102] The PSP Go has the ability to use Bluetooth connections with the Skype application, in addition to its built-in microphone.[103] Skype for PlayStation Vita may be downloaded via the PlayStation Network in the U.Southward. It includes the capability to receive incoming calls with the awarding running in the background.
  • The Samsung Smart TV had a Skype app, which could exist downloaded for free.[104] It used the built-in camera and microphone for the newer models. Alternatively, a separate mountable Skype camera with built-in speakers and microphones is available to purchase for older models.[105] This functionality has now been disabled along with any other "TV Based" Skype clients.
  • Some devices were made to piece of work with Skype by talking to a desktop Skype client or by embedding Skype software into the device. These were usually either tethered to a PC or have a born Wi-Fi client to allow calling from Wi-Fi hotspots, like the Netgear SPH101 Skype Wi-Fi Phone, the SMC WSKP100 Skype Wi-Fi Phone, the Belkin F1PP000GN-SK Wi-Fi Skype Phone, the Panasonic KX-WP1050 Wi-Fi Telephone for Skype Executive Travel Prepare, the IPEVO And then-20 Wi-Fi Phone for Skype and the Linksys CIT200 Wi-Fi Phone.

Third-party licensing [edit]

Third-party developers, such as Truphone, Nimbuzz, and Fring, previously allowed Skype to run in parallel with several other competing VoIP/IM networks (Truphone and Nimbuzz provide TruphoneOut and NimbuzzOut as a competing paid service) in any Symbian or Coffee environment. Nimbuzz made Skype available to BlackBerry users and Fring provided mobile video calling over Skype as well as support for the Android platform. Skype disabled access to Skype by Fring users in July 2010.[106] Nimbuzz discontinued support of Skype on request in October 2010.[107]

Before and during the Microsoft acquisition, Skype withdrew licensing from several tertiary parties producing software and hardware compatible with Skype. The Skype for Asterisk product from Digium was withdrawn every bit "no longer available for sale".[108] The Senao SN358+ long-range (10–15 km) cordless phone was discontinued due to loss of licenses to participate in the Skype network as peers. In combination, these two products made it possible to create roaming cordless mesh networks with a robust handoff.

Engineering science [edit]

Protocol [edit]

Skype uses a proprietary Internet telephony (VoIP) network chosen the Skype protocol. The protocol has non been made publicly available past Skype, and official applications using the protocol are also proprietary. Part of the Skype applied science relies on the Global Index P2P protocol belonging to the Joltid Ltd. corporation. The principal deviation between Skype and standard VoIP clients is that Skype operates on a peer-to-peer model (originally based on the Kazaa software[109]), rather than the more than usual client–server model (notation that the very popular Session Initiation Protocol (SIP) model of VoIP is also peer-to-peer, but implementation by and large requires registration with a server, as does Skype).

On 20 June 2014, Microsoft announced the deprecation of the old Skype protocol. Within several months from this date, in order to keep using Skype services, Skype users will have to update to Skype applications released in 2014. The new Skype protocol—Microsoft Notification Protocol 24 was released. The deprecation became effective in the second week of August 2014. Transferred files are now saved on central servers.

As far as networking stack support is concerned, Skype only supports the IPv4 protocol. It lacks support for the next-generation Net protocol, IPv6.[110] Skype for Business, all the same, includes back up for IPv6 addresses, along with continued support of IPv4.[111]

Protocol detection and control [edit]

Many networking and security companies have claimed to detect and control Skype's protocol for enterprise and carrier applications. While the specific detection methods used by these companies are often individual, Pearson's chi-squared examination and naive Bayes classification are two approaches that were published in 2008.[112] Combining statistical measurements of payload properties (such as byte frequencies and initial byte sequences) also as menstruation properties (like packet sizes and bundle directions) has also shown to exist an effective method for identifying Skype's TCP- and UDP-based protocols.[113]

Sound codecs [edit]

Skype 2.x used Chiliad.729, Skype 3.2 introduced SVOPC, and Skype iv.0 added a Skype-created codec called SILK, intended to be "lightweight and embeddable".[114] Additionally, Skype has released Opus as a costless codec, which integrates the SILK codec principles for vox manual with the CELT codec principles for higher-quality sound transmissions, such as alive music performances. Opus was submitted to the Internet Engineering Task Force (IETF) in September 2010.[115] Since then, it has been standardized every bit RFC 6716.[116]

Video codecs [edit]

VP7 is used for versions prior to Skype 5.5.[117] [118] [119] [120] [121]

As of version 7.0, H.264 is used for both group and one-on-one video chat, at standard definition, 720p and 1080p loftier-definition.[122] [123]

Skype Qik [edit]

Skype acquired the video service Qik in 2011. After shutting down Qik in April 2014, Skype relaunched the service equally Skype Qik on 14 October 2014. Although Qik offered video conferencing and Cyberspace streaming, the new service focuses on mobile video messaging betwixt individuals and groups.[124]

Hyperlink format [edit]

Skype uses URIs as skype:USER?call for a call.[125]

Security and privacy [edit]

Skype was claimed initially to be a secure communication, with one of its early web pages stating "highly secure with end-to-end encryption".[126] Security services were invisible to the user, and encryption cannot exist disabled. Skype claims to utilise publicly documented, widely trusted encryption techniques for Skype-to-Skype communication: RSA for key negotiation and the Advanced Encryption Standard to encrypt conversations.[127] However, it is impossible to verify that these algorithms are used correctly, completely, and at all times, as there is no public review possible without a protocol specification and/or the program'south source code. Skype provides an uncontrolled registration system for users with no proof of identity. Instead, users may choose a screen name which does non have to relate to their real-life identity in whatsoever manner; a name chosen could too be an impersonation attempt, where the user claims to be someone else for fraudulent purposes. A third-political party newspaper analyzing the security and methodology of Skype was presented at Black Hat Europe 2006. Information technology analyzed Skype and plant a number of security issues with the then-current security model.[128]

Skype incorporates some features that tend to hibernate its traffic, just it is not specifically designed to thwart traffic analysis and therefore does not provide bearding communication. Some researchers have been able to watermark the traffic so that information technology is identifiable even after passing through an anonymizing network.[130]

In an interview, Kurt Sauer, the Chief Security Officer of Skype, said, "Nosotros provide a safe communication option. I will non tell you whether we can heed or not."[131] This does not deny the fact that the U.S. National Security Agency (NSA) monitors Skype conversations. Skype'south client uses an undocumented and proprietary protocol. The Gratuitous Software Foundation (FSF) is concerned about user privacy bug arising from using proprietary software and protocols and has made a replacement for Skype 1 of their high-priority projects.[132] Security researchers Biondi and Desclaux have speculated that Skype may take a dorsum door, since Skype sends traffic fifty-fifty when it is turned off and because Skype has taken farthermost measures to obfuscate the programme's traffic and functioning.[133] Several media sources reported that at a meeting about the "Lawful interception of IP based services" held on 25 June 2008, high-ranking unnamed officials at the Austrian interior ministry said that they could listen in on Skype conversations without problems. Austrian public broadcasting service ORF, citing minutes from the coming together, reported that "the Austrian police are able to listen in on Skype connections". Skype declined to annotate on the reports.[134] [135] One easily demonstrated method of monitoring is to fix up 2 computers with the same Skype user ID and password. When a message is typed or a call is received on 1 computer, the second computer duplicates the audio and text. This requires noesis of the user ID and password.

The U.s. Federal Communications Commission (FCC) has interpreted the Communications Aid for Police Enforcement Deed (CALEA) as requiring digital phone networks to allow wiretapping if authorized by an FBI warrant, in the same way as other phone services. In February 2009, Skype said that, not existence a telephone company owning phone lines, information technology is exempt from CALEA and similar laws, which regulate US telephone companies, and it is non clear whether Skype could support wiretapping even if it wanted to.[136] According to the ACLU, the Act is inconsistent with the original intent of the Fourth Amendment to the U.S. Constitution;[137] more recently, the ACLU has expressed the business that the FCC interpretation of the Act is incorrect.[138] [139] It has been suggested that Microsoft made changes to Skype's infrastructure to ease various wiretapping requirements;[140] however, Skype denies the claims.[141]

Sometime before Skype was sold in 2009, the company had started Project Chess, a program to explore legal and technical ways to easily share calls with intelligence agencies and law enforcement.[142]

On 20 February 2009, the European Union's Eurojust agency announced that the Italian Desk at Eurojust would "play a key role in the coordination and cooperation of the investigations on the use of cyberspace telephony systems (VoIP), such every bit 'Skype'. [...] The purpose of Eurojust's coordination role is to overcome the technical and judicial obstacles to the interception of internet telephony systems, taking into account the various data protection rules and civil rights."[143]

In November 2010, a flaw was disclosed to Skype that showed how figurer crackers could secretly rails any user's IP address.[144] Due to Skype's peer-to-peer nature, this was a difficult issue to address, but this bug was eventually remedied in a 2016 update.[145]

In 2012, Skype introduced automated updates to amend protect users from security risks but received some challenge from users of the Mac production, as the updates cannot be disabled from version 5.half dozen on,[146] both on Mac OS and Windows versions, although in the latter, and only from version five.9 on, automatic updating can be turned off in certain cases.[147]

According to a 2012 Washington Post commodity, Skype "has expanded its cooperation with law enforcement authorities to make online chats and other user information available to police"; the article additionally mentions Skype fabricated changes to let regime access to addresses and credit bill of fare numbers.[148]

In November 2012, Skype was reported to have handed over user data of a pro-WikiLeaks activist to Dallas, Texas-based private security company iSIGHT Partners without a warrant or courtroom order. The alleged handover would be a breach of Skype'south privacy policy. Skype responded with a statement that information technology launched an internal investigation to probe the alienation of user data privacy.[149]

On xiii November 2012, a Russian user published a flaw in Skype's security, which allowed any person to take over a Skype account knowing only the victim's email past post-obit 7 steps.[150] [151] This vulnerability was claimed to exist for months and existed for more than than 12 hours since published widely.

On 14 May 2013, information technology was documented that a URL sent via a Skype instant messaging session was usurped by the Skype service and afterward used in a HTTP HEAD query originating from an IP address registered to Microsoft in Redmond (the IP accost used was 65.52.100.214). The Microsoft query used the full URL supplied in the IM conversation and was generated past a previously undocumented security service.[152] Security experts speculate the action was triggered past a technology like to Microsoft's SmartScreen Filter used in its browsers.[153]

The 2013 mass surveillance disclosures revealed that agencies such equally the NSA and the FBI have the ability to eavesdrop on Skype, including the monitoring and storage of text and video calls and file transfers.[154] [155] [156] The PRISM surveillance program, which requires FISA court authorization, reportedly has allowed the NSA unfettered access to its data center supernodes. According to the leaked documents, integration work began in November 2010, but information technology was not until February 2011 that the company was served with a directive to comply signed by the attorney general,[154] with NSA documents showing that drove began on 31 March 2011.[157]

On 10 November 2014, Skype scored 1 out of 7 points on the Electronic Frontier Foundation's secure messaging scorecard. Skype received a point for encryption during transit but lost points because communications are not encrypted with a key the provider does not have admission to (i.eastward. the communications are non end-to-end encrypted), users cannot verify contacts' identities, past messages are not secure if the encryption keys are stolen (i.e. the service does not provide forward secrecy), the lawmaking is not open up to independent review (i.eastward. not available to merely view, nor nether a free-software license), the security blueprint is not properly documented, and there has non been a contempo independent security audit.[158] [159] [160] AIM, BlackBerry Messenger, Ebuddy XMS, Hushmail, Kik Messenger, Viber and Yahoo Messenger too scored i out of vii points.[158]

As of August 2018, Skype now supports end-to-stop encryption across all platforms.[161]

Cybercrime on awarding [edit]

Cybersex trafficking has occurred on Skype[162] [163] [164] [165] and other videoconferencing applications.[166] According to the Australian Federal Constabulary, overseas pedophiles are directing kid sex abuse using its live streaming services.[167] [165]

Service in the People's Democracy of China [edit]

Since September 2007, users in China trying to download the Skype software client have been redirected to the site of TOM Online, a joint venture between a Chinese wireless operator and Skype, from which a modified Chinese version can be downloaded.[168] The TOM customer participates in Red china's organisation of Cyberspace censorship, monitoring text messages between Skype users in Prc also every bit letters exchanged with users outside the country.[169] [170] Niklas Zennström, then chief executive of Skype, told reporters that TOM "had implemented a text filter, which is what everyone else in that market is doing. Those are the regulations." He besides stated, "One thing that's sure is that those things are in no mode jeopardising the privacy or the security of whatever of the users."[171]

In October 2008, information technology was reported that TOM had been saving the full message contents of some Skype text conversations on its servers, apparently focusing on conversations containing political issues such as Tibet, Falun Gong, Taiwan independence, and the Chinese Communist Political party. The saved messages contain personally identifiable information about the bulletin senders and recipients, including IP addresses, usernames, landline phone numbers, and the entire content of the text letters, including the fourth dimension and date of each bulletin. Information almost Skype users outside China who were communicating with a TOM-Skype user was also saved.
