Abbreviation(s) and Synonym(s):

Definition(s):

  The set of attribute values (i.e., characteristics) by which an entity is recognizable and that, within the scope of an identity manager’s responsibility, is sufficient to distinguish that entity from any other entity.
Source(s):
NIST SP 800-161 under Identity from CNSSI 4009
NISTIR 7622 under Identity from CNSSI 4009-2010

  The process of discovering the true identity (i.e., origin, initial history) of a person or item from the entire collection of similar persons or items.

NIST SP 800-79-2 under Identification
FIPS 201 [version unknown] under Identification

  The process of verifying the identity of a user, process, or device, usually as a prerequisite for granting access to resources in an IT system.

NIST SP 800-82 Rev. 2 under Identification from NIST SP 800-47
NIST SP 800-47 [Superseded] under Identification

  Unique data used to represent a person’s identity and associated attributes. A name or a card number are examples of identifiers.

NIST SP 800-63-3 under Identity

  A bit string that is associated with a person, device or organization. It may be an identifying name, or may be something more abstract (for example, a string consisting of an Internet Protocol (IP) address).
Source(s):
NIST SP 800-56B Rev. 2 under Identifier

  A bit string that is associated with a person, device, or organization. It may be an identifying name or may be something more abstract (e.g., a string consisting of an IP address and timestamp), depending on the application.
Source(s):
NIST SP 800-57 Part 1 Rev. 5 under Identifier

  A set of attributes that uniquely describe a person within a given context.
Source(s):
NISTIR 8149 under Identity from NIST SP 800-63-3
NIST SP 800-63-2 [Superseded] under Identity

  A unique, auditable representation of identity within the system usually in the form of a simple character string for each individual user, machine, software component or any other entity.
Source(s):
NISTIR 5153 under Identification

  Something (data) that identifies an assessment object or other entity of interest (like a defect check). In database terms, it is a primary or candidate key that can be used to uniquely identify the assessment object so it is not confused with other objects.
