TLDR
In this paper, two or more digital watermarks with different characteristics are embedded in a document and the characteristics are chosen so that the watermarks will be affected in different manners if the document is subsequently copied or reproduced.Abstract:
Two or more digital watermarks, with different characteristics, are embedded in a document. The characteristics are chosen so that the watermarks will be affected in different manners if the document is subsequently copied or reproduced. The detection process or mechanism reads two or more of the watermarks and compares their characteristics. While wear and handling may change the characteristics of the digital watermarks in a document, the relationship between the characteristics of the multiple digital watermarks in a document will nevertheless give an indication as to whether a document is an original or a copy of an original. Document wear can be independently assessed and used as an aid in interpreting the detected watermark characteristics.read more

Patent
Connected audio and other media objects
TL;DR: In this paper, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc.

Integrating digital watermarks in multimedia content
TL;DR: In this paper, a copy control method for decoding auxiliary data from media signals in multimedia content decodes watermarks from different media signals and uses the watermarks to control processing of the multimedia content.

Hugh L. Brunk,Kenneth L. Levy +1 more
TL;DR: The presently claimed invention generally relates to deriving and/or utilizing content signatures (e.g., so-called "fingerprints") as mentioned in this paper, which is a method of generating a fingerprint associated with a content item including: pseudo-randomly selecting a segment of the content item; and utilizing a processor or electronic processing circuitry, fingerprinting the selected segment of content item as at least an identifier of the item.

System and method for optimized funding of electronic transactions
TL;DR: In this article, a decision reference data store is used for communicating second information regarding parameters for use in determining a payment option for the payment request, and then the processor selectably determines the payment option to direct a transmission of funds from at least one payment source to one payee account based on an optimization determination performed by the processor.

Systems and Methods for Secure Transaction Management and Electronic Rights Protection
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
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.
