Evercookie
Evercookie (also known as supercookie) is a JavaScript application programming interface (API) that identifies and reproduces intentionally deleted cookies on the clients' browser storage. It was created by Samy Kamkar in 2010 to demonstrate the possible infiltration from the websites that use respawning. Websites that have adopted this mechanism can identify users even if they attempt to delete the previously stored cookies. In 2013, Edward Snowden leaked a top-secret NSA document that showed Evercookie can track Tor (anonymity networks) users. Many popular companies use functionality similar to Evercookie to collect user information and track users. Further research on fingerprinting and search engines also draws inspiration from Evercookie's ability to track a user persistently. Background There are three commonly used data storages, including HTTP cookies, flash cookies, HTML5 Storage, and others. When the user visits a website for the first time, the web server may generate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canvas Fingerprinting
Canvas fingerprinting is one of a number of browser fingerprinting techniques for tracking online users that allow websites to identify and track visitors using the HTML5 canvas element instead of browser cookies or other similar means. The technique received wide media coverage in 2014 after researchers from Princeton University and KU Leuven University described it in their paper ''The Web never forgets''. Description Canvas fingerprinting works by exploiting the HTML5 canvas element. As described by Acar et al. in: Variations in which the graphics processing unit (GPU), or the graphics driver, is installed may cause the fingerprint variation. The fingerprint can be stored and shared with advertising partners to identify users when they visit affiliated websites. A profile can be created from the user's browsing activity, allowing advertisers to target advertise to the user's inferred demographics and preferences. By January 2022, the concept was extended to fingerprinting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HTTP Cookie
HTTP cookies (also called web cookies, Internet cookies, browser cookies, or simply cookies) are small blocks of data created by a web server while a user is browsing a website and placed on the user's computer or other device by the user's web browser. Cookies are placed on the device used to access a website, and more than one cookie may be placed on a user's device during a session. Cookies serve useful and sometimes essential functions on the web. They enable web servers to store stateful information (such as items added in the shopping cart in an online store) on the user's device or to track the user's browsing activity (including clicking particular buttons, logging in, or recording which pages were visited in the past). They can also be used to save for subsequent use information that the user previously entered into form fields, such as names, addresses, passwords, and payment card numbers. Authentication cookies are commonly used by web servers to authenticate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Device Fingerprint
A device fingerprint or machine fingerprint is information collected about the software and hardware of a remote computing device for the purpose of identification. The information is usually assimilated into a brief identifier using a fingerprinting algorithm. A browser fingerprint is information collected specifically by interaction with the web browser of the device. Device fingerprints can be used to fully or partially identify individual devices even when persistent cookies (and zombie cookies) cannot be read or stored in the browser, the client IP address is hidden, or one switches to another browser on the same device. This may allow a service provider to detect and prevent identity theft and credit card fraud, but also to compile long-term records of individuals' browsing histories (and deliver targeted advertising or targeted exploits) even when they are attempting to avoid tracking – raising a major concern for internet privacy advocates.

Local Shared Object
A local shared object (LSO), commonly called a Flash cookie (due to its similarity with an HTTP cookie), is a piece of data that websites that use Adobe Flash may store on a user's computer. Local shared objects have been used by all versions of Flash Player (developed by Macromedia, which was later acquired by Adobe Systems) since version 6. Flash cookies, which can be stored or retrieved whenever a user accesses a page containing a Flash application, are a form of local storage. Similar to cookies, they can be used to store user preferences, save data from Flash games, or track users' Internet activity. LSOs have been criticised as a breach of browser security, but there are now browser settings and addons to limit the duration of their storage. Storage Local shared objects contain data stored by individual websites. Data is stored in the Action Message Format. With the default settings, the Flash Player does not seek the user's permission to store local shared objects on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Real-time Bidding
Real-time bidding (RTB) is a means by which advertising inventory is bought and sold on a per- impression basis, via instantaneous programmatic auction, similar to financial markets. With real-time bidding, advertising buyers bid on an impression and, if the bid is won, the buyer's ad is instantly displayed on the publisher's site. Real-time bidding lets advertisers manage and optimize ads from multiple ad-networks, allowing them to create and launch advertising campaigns, prioritize networks, and allocate percentages of unsold inventory, known as backfill. Real-time bidding is distinguishable from static auctions by how it is a per-impression way of bidding, whereas static auctions are groups of up to several thousand impressions. RTB is promoted as being more effective than static auctions for both advertisers and publishers in terms of advertising inventory sold, though the results vary by execution and local conditions. RTB replaced the traditional model. Research suggests that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Tracking
Web tracking is the practice by which operators of websites and third parties collect, store and share information about visitors’ activities on the World Wide Web. Analysis of a user's behaviour may be used to provide content that enables the operator to infer their preferences and may be of interest to various parties, such as advertisers. Web tracking can be part of visitor management. Uses of web tracking The uses of web tracking include the following: * Advertising companies actively collect information about users and make profiles that are used to individualize advertisements. User activities include websites visited, watched videos, interactions on social networks, and online transactions. Websites like Netflix, YouTube collect information about what shows users watch, which helps them suggest more shows that they might like. Search engines like Google will keep a record of what users search for, which could help them suggest more relevant searches in the future. * L ...
