User Registration
A registered user is a user of a website, program, or other systems who has previously ''registered.'' Registered users normally provide some sort of credentials (such as a username or e-mail address, and a password) to the system in order to prove their identity: this is known as logging in. Systems intended for use by the general public often allow any user to register simply by selecting a ''register'' or ''sign up'' function and providing these credentials for the first time. Registered users may be granted privileges beyond those granted to unregistered users. Rationale User registration and login enables a system to personalize itself. For example, a website might display a welcome banner with the user's name and change its appearance or behavior according to preferences indicated by the user. The system may also allow a logged-in user to send and receive messages, and to view and modify personal files or other information. Criticism Privacy concerns Registration nec ...

User (system)
A user is a person who utilizes a computer or network service. A user often has a user account and is identified to the system by a username (or user name). Other terms for username include login name, screenname (or screen name), account name, nickname (or nick) and handle, which is derived from the identical citizens band radio term. Some software products provide services to other systems and have no direct end users. End user End users are the ultimate human users (also referred to as operators) of a software product. The end user stands in contrast to users who support or maintain the product such as sysops, database administrators and computer technician A computer repair technician is a person who repairs and maintains computers and servers. The technician's responsibilities may extend to include building or configuring new hardware, installing and updating software packages, and creating and ...s. The term is used to abstract and distinguish those who only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Access Control
In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process. The act of ''accessing'' may mean consuming, entering, or using. Permission to access a resource is called ''authorization''. Locks and login credentials are two analogous mechanisms of access control. Physical security Geographical access control may be enforced by personnel (e.g. border guard, bouncer, ticket checker), or with a device such as a turnstile. There may be fences to avoid circumventing this access control. An alternative of access control in the strict sense (physically controlling access itself) is a system of checking authorized presence, see e.g. Ticket controller (transportation). A variant is exit control, e.g. of a shop (checkout) or a country. The term access control refers to the practice of restricting entrance to a property, a building, or a room to ...

Unique User
Website popularity is commonly determined using the number of unique users, and the metric is often quoted to potential advertisers or investors. A website's number of unique users is usually measured over a standard period of time, typically a month. Limitations Use of performance indicators like unique visitors/users has been criticized. Greg Harmon of Belden Research inferred that many companies reporting their online performance "may overstate" the number of unique visitors due to the limitations of the metric. This is because an increasing number of people now access websites through multiple physical devices with different IP addresses, and thus may be counted multiple times. Websites that track users using cookies instead of IP addresses are not safe either, as some users regularly delete cookies from their devices, and others may use multiple web browsers to access a single website. This means that for a typical news site, for example, which people might visit more than o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid (web Decentralization Project)
Solid (Social Linked Data) is a web decentralization project led by Sir Tim Berners-Lee, the inventor of the World Wide Web, originally developed collaboratively at the Massachusetts Institute of Technology (MIT). The project "aims to radically change the way Web applications work today, resulting in true data ownership as well as improved privacy" by developing a platform for linked-data applications that are completely decentralized and fully under users' control rather than controlled by other entities. The ultimate goal of Solid is to allow users to have full control of their own data, including access control and storage location. To that end, Tim Berners-Lee formed a company called Inrupt to help build a commercial ecosystem to fuel Solid. History Two decades after Berners-Lee invented the World Wide Web in 1989, he outlined the design issues of what later became the Solid project in drafts he wrote for the World Wide Web Consortium. Berners-Lee became increasingly disma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Identification
An electronic identification ("eID") is a digital solution for proof of identity of citizens or organizations. They can be used to view to access benefits or services provided by government authorities, banks or other companies, for mobile payments, etc. Apart from online authentication and login, many electronic identity services also give users the option to sign electronic documents with a digital signature. One form of eID is an electronic identification card (eIC), which is a physical identity card that can be used for online and offline personal identification or authentication. The eIC is a smartcard in ID-1 format of a regular bank card, with identity information printed on the surface (such as personal details and a photograph) and in an embedded RFID microchip, similar to that in biometric passports. The chip stores the information printed on the card (such as the holder's name and date of birth) and the holder's photo(s). Several photos may be taken from different an ...

Do Not Track
Do Not Track (DNT) is a formerly official HTTP header field, designed to allow internet users to opt-out of tracking by websites—which includes the collection of data regarding a user's activity across multiple distinct contexts, and the retention, use, or sharing of data derived from that activity outside the context in which it occurred. The Do Not Track header was originally proposed in 2009 by researchers Christopher Soghoian, Sid Stamm, and Dan Kaminsky. Mozilla Firefox became the first browser to implement the feature, while Internet Explorer, Apple's Safari, Opera and Google Chrome all later added support. Efforts to standardize Do Not Track by the W3C in the Tracking Preference Expression (DNT) Working Group reached only the Candidate Recommendation stage and ended in September 2018 due to insufficient deployment and support. DNT is not widely adopted by the industry, with companies citing the lack of legal mandates for its use, as well as unclear standards and guideli ...

Background Check
A background check is a process a person or company uses to verify that an individual is who they claim to be, and this provides an opportunity to check and confirm the validity of someone's criminal record, education, employment history, and other activities from their past. The frequency, purpose, and legitimacy of background checks vary among countries, industries, and individuals. An employment background check typically takes place when someone applies for a job, but it can also happen at any time the employer deems necessary. A variety of methods are used to complete these checks including thoroughly verifying references, conducting detailed online searches, utilizing third-party services or agencies when appropriate, depending on the sensitivity of the position or industry regulations, checking academic records, and conducting criminal record checks. All of these steps help employers identify any potential risks associated with hiring an individual and make well-informed dec ...

Active Users
Active users is a measurement metric that is commonly used to measure the level of engagement for a particular product or object, by quantifying the number of active interactions from visitors within a relevant range of time (daily, weekly and monthly). The metric has many uses in both commerce and academia, such as on social networking services, online games, or mobile apps. Although having extensive uses in digital behavioural learning, prediction and reporting, it also has impacts on the privacy and security, and ethical factors should be considered thoroughly. Like any metric, active users may have limitations and criticisms. The term is relatively neologistic in nature, becoming important with the rise of the commercialised internet, with uses in communication and Social networking service, social-networking. It measures how many users visit or interact with the product or service over a given interval or period. This metric is commonly assessed per month as monthly active ...

Social Security Number
In the United States, a Social Security number (SSN) is a nine-digit number issued to U.S. citizens, permanent residents, and temporary (working) residents under section 205(c)(2) of the Social Security Act, codified as . The number is issued to an individual by the Social Security Administration, an independent agency of the United States government. Although the original purpose for the number was for the Social Security Administration to track individuals, the Social Security number has become a ''de facto'' national identification number for taxation and other purposes. A Social Security number may be obtained by applying on Form SS-5, Application for a Social Security Number Card. History Social Security numbers were first issued by the Social Security Administration in November 1936 as part of the New Deal Social Security program. Within three months, 25 million numbers were issued. On November 24, 1936, 1,074 of the nation's 45,000 post offices were designated "typing ...

Website
A website (also written as a web site) is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Examples of notable websites are Google Search, Google, Facebook, Amazon (website), Amazon, and Wikipedia. All publicly accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a intranet, private network, such as a company's internal website for its employees. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. User (computing), Users can access websites on a range of devices, including desktop computer, desktops, laptops, tablet computer, tablets, and smartphones. The application software, app used on these devices is called a Web browser. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Search Engine
A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). When a user enters a query into a search engine, the engine scans its index of web pages to find those that are relevant to the user's query. The results are then ranked by relevancy and displayed to the user. The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories and social bookmarking sites, which are maintained by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Any internet-based content that can't be indexed and searched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Privacy Policies
A privacy policy is a statement or legal document (in privacy law) that discloses some or all of the ways a party gathers, uses, discloses, and manages a customer or client's data. Personal information can be anything that can be used to identify an individual, not limited to the person's name, address, date of birth, marital status, contact information, ID issue, and Expiration date, expiry date, financial records, credit information, medical history, where one travels, and intentions to acquire goods and services. In the case of a business, it is often a statement that declares a party's policy on how it collects, stores, and releases personal information it collects. It informs the client what specific information is collected, and whether it is kept confidential, shared with partners, or sold to other firms or enterprises. Privacy policies typically represent a broader, more generalized treatment, as opposed to Data mining, data use statements, which tend to be more detailed an ...
