| description | A photographic identification document (10) comprises a photograph (12) and a printed region (11). A first digital watermark is steganographically encoded in the photograph (12), the digital watermark conveying first information that can later be decoded and used to authenticate the document (10). In addition, a second digital watermark is steganographically encoded in the printed region (11) of the document (10), the second digital watermark conveying second information whose contents have an expected correspondence with contents of said first information, wherein said first and second information can be decoded and checked for said expected correspondence to aid in determining whether said photograph (12) or said printed region (11) has been fraudulently altered. |
