Identification document and related methods

Trent J. Brundage, +8 more
TLDR
In this paper, the authors provide methods and systems for authenticating identification documents (100) including two or more digital watermarks (27, 60), which correspond with each other or with indicia carried by the identification document (100).
Abstract: 
The present invention provides methods and systems for authenticating identification documents (100). We also teach an identification document (100) including two or more digital watermarks (27, 60). The watermarks correspond with each other or with indicia carried by the identification document (100). The correspondence can be verified to determine authenticity. We also provide digital watermark detection methods and systems to identify the different watermarks (100) through embedded orientation components. We then focus watermark message-decoding efforts on areas identified as likely including watermark orientation components (27, 60). In one implementation we provide a watermark detection trigger to identify so-called legacy documents. The trigger may indicate the presence or expected absence of a digital watermark. In other implementations we provide a versatile document authenticator to toggle between watermarking and non-watermarking authentication processes depending on a detection trigger (100).

Systems and Methods for Secure Transaction Management and Electronic Rights Protection

Karl L Ginter, +3 more
TL;DR: In this article, the authors proposed a secure content distribution method for a configurable general-purpose electronic commercial transaction/distribution control system, which includes a process for encapsulating digital information in one or more digital containers, a process of encrypting at least a portion of digital information, a protocol for associating at least partially secure control information for managing interactions with encrypted digital information and/or digital container, and a process that delivering one or multiple digital containers to a digital information user.

Secure spread spectrum watermarking for multimedia

Ingemar J. Cox, +3 more
- 01 Dec 1997 - 
TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
