Abstract:
An apparatus for managing access to a cryptographically secured access-controlled datum, comprising: (a) computer-implemented input logic means for receiving a candidate access code; (b) a first computer memory configured to store a cryptographically camouflaged access-controlled datum; (c) computer-implemented first cryptographic logic means operatively connected to said input logic means, and to said first computer memory, for processing said cryptographically camouflaged access-controlled datum using said candidate access code, said processing inhibiting the detection of cryptographic camouflaging by a fraudulent provider of said candidate access code by preserving a structural homogeneity corresponding to a pre-camouflaged state of said access-controlled datum; and (d) computer-implemented output logic means for providing said processed access-controlled datum to a user of said apparatus.
