ABSTRACT:
A system and method for generating a signed hardcopy document and authentication thereof is provided. A data representation including digital data is recorded from a hardcopy document. The digital data is compressed using a compression scheme including one of low-fidelity compression and symbol-based compression. An authentication token is generated from the compressed digital data. The authentication token is encoded. A signed hardcopy document including both the encoded authentication token and the data representation is printed.
