Abstract (en)

[origin: WO0049797A1] An enhanced digital camera includes a non-volatile memory in which is stored a security value used to produce digital signatures for photographs. A processor within the enhanced digital camera processes a photograph by hashing digital data for the photograph to produce a hash digest. The processor then performs a digital signature function using the security value in order to produce a digital signature for the photograph.
