  • Apparatus and method for cryptographic operations using enhanced knowledge factor credentials
    Patent number: 10015163
    Abstract: Provided is a process that includes: authenticating a user based on a sequence of transactions that specify a knowledge factor credential where the knowledge-factor credential is lower entropy than the sequence of user-entered transactions, such that possession of the fully entered knowledge-factor credential, without possession of the sequence of user-entered transactions, does not reveal all of the user-entered transactions by which the fully entered knowledge-factor credential was specified by the user.

  • Apparatus and method for cryptographic operations using enhanced knowledge factor credentials
    Patent number: 9516015
    Abstract: Provided is a process that includes: obtaining a multi-byte character set specifying a plurality of characters; receiving a knowledge factor credential encoded with a plurality of characters of the multi-byte character set, wherein the knowledge factor credential has a longer effective length than an apparent length, and wherein the knowledge factor credential has at least one character outside of a block of characters designated for a locale of the computing device; and providing the knowledge factor credential to authenticate a user.
