Patent attributes
A system and method of authenticating a digital still image captured using a digital image capture device. To process the digital still image for later authentication, a signature data is transmitted from a remote location to the digital image capture device. Upon capturing the digital still image, an image identification is associated with the digital still image. The signature data is then applied to the captured digital still image to produce an authentication signature representative of the captured digital still image. The authentication signature is associated with the image identification and transmitted from the digital still image to the remote location for storage at the remote location. To verify the authenticity of the digital still image, the digital still image is transmitted to the remote location. The signature data for the transmitted digital still image is accessed and applied to the transmitted digital still image to produce a verification signature. The authentication signature and the verification signature are compared to determine the authentication of the transmitted digital still image. In an alternate embodiment, the signature data and image identification are sent to the image capture device to generate the verification signature, which is transmitted to the remote location for comparison with the authentication signature.
