Jingwang Weishi
Jingwang Weishi () is a content-control mobile app developed by Shanghai Landasoft Data Technology Inc. It is known for its use by the police in Xinjiang, China. Function In 2018, a research team of analysts conducted a thorough report on Jingwang Weishi. When the application is first installed, it sends a request to the base server. The server responds with a JSON object containing a list of MD5 hashes, which the program stores in a local SQLite database. The application records the "essential information", as the program's code calls it, of its device. Specifically, the essential information consists of the device's International Mobile Equipment Identity (IMEI) number, MAC address, manufacturer, model, phone number, and international mobile subscriber identity (IMSI) number. Jingwang Weishi also performs file scans on the device. It looks for files with the extensions 3GP, AMR, AVI, WEBM, FLV, IVX, M4A, MP3, MP4, MPG, RMVB, RAM, WMA, WMV, TXT, HTML, CHM, PNG, and JPG ...

Content-control Software
An Internet filter is software that restricts or controls the content an Internet user is capable to access, especially when utilized to restrict material delivered over the Internet via the Web, Email, or other means. Content-control software determines what content will be available or be blocked. Such restrictions can be applied at various levels: a government can attempt to apply them nationwide (see Internet censorship), or they can, for example, be applied by an Internet service provider to its clients, by an employer to its personnel, by a school to its students, by a library to its visitors, by a parent to a child's computer, or by an individual users to their own computers. The motive is often to prevent access to content which the computer's owner(s) or other authorities may consider objectionable. When imposed without the consent of the user, content control can be characterised as a form of internet censorship. Some content-control software includes time control fun ...

RealAudio
RealAudio, or also spelled as Real Audio is a proprietary audio format developed by RealNetworks and first released in April 1995. It uses a variety of audio codecs, ranging from low-bitrate formats that can be used over dialup modems, to high-fidelity formats for music. It can also be used as a streaming audio format, that is played at the same time as it is downloaded. In the past, many internet radio stations used RealAudio to stream their programming over the internet in real time. In recent years, however, the format has become less common and has given way to more popular audio formats. RealAudio was heavily used by the BBC websites until 2009, though it was discontinued due to its declining use. BBC World Service, the last of the BBC websites to use RealAudio, discontinued its use in March 2011. File extensions RealAudio files were originally identified by a filename extension of .ra (for Real Audio). In 1997, RealNetworks also began offering a video format called RealVide ...

Mass Surveillance In China
Mass surveillance in the People's Republic of China (PRC) is the network of monitoring systems used by the Chinese central government to monitor Chinese citizens. It is primarily conducted through the government, although corporate surveillance in connection with the Chinese government has been reported to occur. China monitors its citizens through internet, camera as well as through other digital technologies. It has become increasingly widespread and grown in sophistication under General Secretary of the Chinese Communist Party (CCP) Xi Jinping's administration. Background Mass surveillance has significantly expanded under the PRC Cybersecurity Law (2016) and with the help of local companies like Tencent, Dahua Technology, Hikvision, SenseTime, ByteDance, Megvii, Huawei and ZTE, among many others. As of 2019, it is estimated that 200 million monitoring CCTV cameras of the "Skynet" system have been put to use in mainland China, four times the number of surveillance cam ...

Uyghurs
The Uyghurs; ; ; ; zh, s=, t=, p=Wéiwú'ěr, IPA: ( ), alternatively spelled Uighurs, Uygurs or Uigurs, are a Turkic ethnic group originating from and culturally affiliated with the general region of Central and East Asia. The Uyghurs are recognized as native to the Xinjiang Uyghur Autonomous Region in Northwest China. They are one of China's 55 officially recognized ethnic minorities. The Uyghurs are recognized by the Chinese government as a regional minority and the titular people of Xinjiang. The Uyghurs have traditionally inhabited a series of oases scattered across the Taklamakan Desert within the Tarim Basin. These oases have historically existed as independent states or were controlled by many civilizations including China, the Mongols, the Tibetans and various Turkic polities. The Uyghurs gradually started to become Islamized in the 10th century and most Uyghurs identified as Muslims by the 16th century. Islam has since played an important role in U ...

Man-in-the-middle Attack
In cryptography and computer security, a man-in-the-middle, monster-in-the-middle, machine-in-the-middle, monkey-in-the-middle, meddler-in-the-middle, manipulator-in-the-middle (MITM), person-in-the-middle (PITM) or adversary-in-the-middle (AiTM) attack is a cyberattack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other, as the attacker has inserted themselves between the two parties. One example of a MITM attack is active eavesdropping, in which the attacker makes independent connections with the victims and relays messages between them to make them believe they are talking directly to each other over a private connection, when in fact the entire conversation is controlled by the attacker. The attacker must be able to intercept all relevant messages passing between the two victims and inject new ones. This is straightforward in many circumstances; for example, an attacker wit ...

Hypertext Transfer Protocol
The Hypertext Transfer Protocol (HTTP) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources that the user can easily access, for example by a mouse click or by tapping the screen in a web browser. Development of HTTP was initiated by Tim Berners-Lee at CERN in 1989 and summarized in a simple document describing the behavior of a client and a server using the first HTTP protocol version that was named 0.9. That first version of HTTP protocol soon evolved into a more elaborated version that was the first draft toward a far future version 1.0. Development of early HTTP Requests for Comments (RFCs) started a few years later and it was a coordinated effort by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C), with work later moving to t ...

Backdoor (computing)
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer" —a tiny computer-within-a-computer such as that found in Intel's AMT technology). Backdoors are most often used for securing remote access to a computer, or obtaining access to plaintext in cryptographic systems. From there it may be used to gain access to privileged information like passwords, corrupt or delete data on hard drives, or transfer information within autoschediastic networks. A backdoor may take the form of a hidden part of a program, a separate program (e.g. Back Orifice may subvert the system through a rootkit), code in the firmware of the hardware, or parts of an operating system such as Windows. Trojan horses can be used to create vulnerabilities in a device. A Trojan horse may appear to be an entirely leg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portable Network Graphics
Portable Network Graphics (PNG, officially pronounced , colloquially pronounced ) is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) — unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF". PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore non-RGB color spaces such as CMYK are not supported. A PNG file contains a single image in an extensible structure of ''chunks'', encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. PNG files use the file extension PNG or pn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Compiled HTML Help
Microsoft Compiled HTML Help is a Microsoft proprietary online help format, consisting of a collection of HTML pages, an index and other navigation tools. The files are compressed and deployed in a binary format with the extension .CHM, for Compiled HTML. The format is often used for software documentation. It was introduced as the successor to Microsoft WinHelp with the release of Windows 95 OSR 2.5 and consequently, Windows 98. Within the Windows NT family, the CHM file support is introduced in Windows NT 4.0 and is still supported in Windows 11. Although the format was designed by Microsoft, it has been successfully reverse-engineered and is now supported in many document viewer applications. History Microsoft has announced that they do not intend to add any new features to HTML Help. File format Help is delivered as a binary file with the .chm extension. It contains a set of HTML files, a hyperlinked table of contents, and an index file. The file format has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
