Online identityInternet identity (IID), also online identity, online personality, online persona or internet persona, is a social identity that an Internet user establishes in online communities and websites. It may also be an actively constructed presentation of oneself. Although some people choose to use their real names online, some Internet users prefer to be anonymous, identifying themselves by means of pseudonyms, which reveal varying amounts of personally identifiable information.
Digital footprintDigital footprint or digital shadow refers to one's unique set of traceable digital activities, actions, contributions, and communications manifested on the Internet or digital devices. Digital footprints can be classified as either passive or active. Passive footprints consist of a user's web-browsing activity and information stored as cookies. Users intentionally create active footprints to share information on websites or social media.
Password managerA password manager is software that stores usernames and passwords in a collection called a password vault. The vault is intended to be encrypted, and its encryption key is commonly derived from a master password chosen by the user. Most password managers can generate passwords, save credentials as they are entered, and fill them when the user returns.
CyberspaceCyberspace is an interconnected digital environment. It is a type of virtual world popularized with the rise of the Internet.
EmailElectronic mail (usually shortened to email; alternatively hyphenated e-mail) is a method of transmitting and receiving digital messages using electronic devices over a computer network. It was conceived in the late–20th century as the digital version of, or counterpart to, mail (hence e- + mail).
OpenIDOpenID is an open standard and decentralized authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated by co-operating sites (known as relying parties, or RP) using a third-party identity provider (IdP) service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to log in to multiple unrelated websites without having to have a separate identity and password for each.Personal dataPersonal data, also known as personal information or personally identifiable information (PII), is any information related to an identifiable person. The abbreviation PII is widely used in the United States, but the phrase it abbreviates has four common variants based on personal or personally, and identifiable or identifying.
Social Security numberIn 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 42 U.S.C.§ 405(c)(2). The number is issued to an individual by the Social Security Administration, an independent agency of the United States government.
Hash functionA hash function is any function that can be used to map data of arbitrary size to fixed-size values, though there are some hash functions that support variable-length output. The values returned by a hash function are called hash values, hash codes, (hash/message) digests, or simply hashes. The values are usually used to index a fixed-size table called a hash table. Use of a hash function to index a hash table is called hashing or scatter-storage addressing.

Convergence of random variablesNotions of probabilistic convergence, applied to estimation and asymptotic analysisIn probability theory, there exist several different notions of convergence of sequences of random variables, including convergence in probability, convergence in distribution, and almost sure convergence. The different notions of convergence capture different properties about the sequence, with some notions of convergence being stronger than others.
Computing platformA computing platform, digital platform, or software platform is the infrastructure on which software is executed. While the individual components of a computing platform may be obfuscated under layers of abstraction, the summation of the required components comprise the computing platform.*As an Amazon Associate I earn from qualifying purchases.
