Abstract:
The method and system embeds digital meta-data into an original image in such a way that the meta-data can be completely removed at a later time to allow loss less recovery of the original image. The loss less recovery of the original image allows for a digital signature of the image to be embedded in the image itself and later recovered and used to verify the authenticity of a received image.
