Abstract: Techniques for proving digital photograph authorship using ECG biometrics are described. Electrodes are located on the exterior of a digital camera and are electrically coupled to an ECG circuit. When a photographer holds the camera with both hands, the electrodes detect electrical voltages from the photographer's hands and the ECG circuit produces a digital ECG signal.

The camera's cryptographic engine uses a cryptographic key to encrypt the watermarked image to produce an encrypted image. If a dispute arises regarding authorship of the photograph, the stenographic and cryptographic engines convert the encrypted image into the raw image file and the photographer's ECG signals, which are compared to the ECG signals of the disputed author(s).
