  "definition" : "Indicator of low digital quality or reliability of the digital reliability of the verification and validation process used to verify the claimed identity of an entity by securely associating an identifier and its authenticator. [Based on ISO 7498-2] \\r\\n\\n                        The degree of confidence in the vetting process used to establish the identity of the individual to whom the credential was issued, and 2) the degree of confidence that the individual who uses the credential is the individual to whom the credential was issued. [OMB M-04-04 E-Authentication Guidance for Federal Agencies] \\r\\n\\n                        Low authentication level of assurance indicates that the relying party may have little or no confidence in the asserted identity's validity. Level 1 requires little or no confidence in the asserted identity. No identity proofing is required at this level, but the authentication mechanism should provide some assurance that the same claimant is accessing the protected transaction or data. A wide range of available authentication technologies can be employed and any of the token methods of Levels 2, 3, or 4, including Personal Identification Numbers (PINs), may be used. To be authenticated, the claimant must prove control of the token through a secure authentication protocol. At Level 1, long-term shared authentication secrets may be revealed to verifiers.  Assertions issued about claimants as a result of a successful authentication are either cryptographically authenticated by relying parties (using approved methods) or are obtained directly from a trusted party via a secure authentication protocol.   [Summary of the technical requirements specified in NIST SP 800-63 for the four levels of assurance defined by the December 2003, the Office of Management and Budget (OMB) issued Memorandum M-04-04, E-Authentication Guidance for Federal Agencies.]",
