Digital Identity
What is Digital Identity ?
  • Digital identity consists of an identity assertion and the characteristics,sometimes called attributes,that are collected or observed through our computerized relationships. It is often as simple as a user name and password. Digital identity is similar to the more complex concept of identity in the real,analog world. However,the differences create profound issues as well as potential for managing our privacy and relationships on the Internet.
  • The potential comes from the separation of the person from their use of computers,of the Internet. There are many computer-based activities where anonymity and complete privacy are possible in a way that they are not in the real world. The issues come out of society’s need to link a digital identity to a real person for accountability and trust in activities like e-Commerce,as well as in conformance to laws.
  • Federated identity,as developed through initiatives like Microsoft’s .net Passport program and the open standards under development in the Liberty Alliance,can help people deal with the multiplicity of these identities and attributes while protecting their privacy.
  • biometrics / biometric authentication
  • In a security context,biometrics and biometric authentication refer to using a person’s physical characteristic in order to authenticate them for access to a resource.

    Some of the characteristics commonly used include those of the eye, face,voice,fingerprints or the shape of a hand. Since these characteristics are unique and change very little over time,they offer strong proof of the person’s identity. Since these authentication systems are much more expensive to acquire and maintain,they are often used for access to very sensitive or classified information.

    It’s easier to attack the stored comparison statistics or images than it is to copy the unique physical characteristic so this becomes a weak point of biometric authentication. These items need to be carefully secured. In addition,biometrics are usually used as a part of a two-factor or strong authentication management system where a password or something known must also be used to gain access.
