ABSTRACT:
Implemented preferably within a digital camera, an electronic device is used to prevent a captured data clip from being fraudulently altered without detection. The electronic device performs "time-bracketing" and may contain cellular phone circuitry to establish wireless communication to receive a state value used to preserve data integrity when time-stamping is performed in combination.
