Classification: CPC G | IPC G

Claim 6:
7. A method comprising:
obtaining a first digital image and a hash associated with the first digital image,
wherein the hash associated with the first digital image is the hash of analog values recorded by a sensor involved in generating the first digital image;

based on the hash, retrieving the analog values from a database;
based on the analog values, reconstructing a second digital image;
determining whether the first digital image and the second digital image are substantially the same by:
obtaining a first multiplicity of pixel values associated with the first digital image and a second multiplicity of pixel values associated with the second digital image;
comparing the first multiplicity of pixel values and the second multiplicity of pixel values to determine a difference;
determining whether the difference is below a predetermined threshold; and
upon determining that the difference is below the predetermined threshold, determining that the first digital image and the second digital image are substantially the same; and

selectively performing providing a first notification that the first digital image is the same as the second digital image or providing a second notification that the first digital image is different from the second digital image, based on determining that the first digital image and the second digital image are not substantially the same.
