摘要： Provides methods for tracing and identifying a piracy in a wireless rights management system, wherein the content provider allow the protected digital content to be super-distributed, when unauthorized holding a pirated copy of the protected digital content is detected, based on the gateway controlling ability of the wireless operator within the wireless digital rights management system, a specific fingerprint is embedded in or removed from the protected digital content so as to trace the suspected persons and further identify the pirate. The fingerprint is related to information of a suspected person holding the protected digital content without authorization. A process of screening singles out highly suspected persons. Therefore the operator can determine whether the suspected person is a real pirate by comparing the similarity of the pirated version of content and the version held by the suspected person, and the exact tracing and identifying is achieved.

摘要： The present invention provides a method of distributing content to a plurality of clients. The method on a server begins with accessing content to be distributed to a plurality of clients and identifying a first type of content to be distributed as crucial content and identifying a second type of content to be distributed as non-crucial content. The crucial content is any content required to properly render, after a decryption process, the content. The non-crucial content is all the other content to be distributed. The crucial content is encrypted with a first encrypting key which is unique to each of the plurality of clients. The crucial content which has been encrypted is transmitted. The non-crucial content is transmitted to the plurality of clients.

摘要： Multi-key content processing systems and methods, for processing content with at least one distribution target position. Each of the distribution target positions corresponds to an authorization key. An example method includes the steps of: encrypting said content with a content key; forming a key link based on said content key and the authorization key of said at least one distribution target position; and attaching said key link to the encrypted content.

摘要： A watermark embedding method for embedding a secret message sequence in a document. The techniques include obtaining layout information of the document, extracting a digest of the document by using a Hash function, calculating embedded positions where the secret message sequence is embedded in the document, and dispersedly hiding the secret message sequence in each of the calculated embedded positions by altering the layout of the document. Also provided is a watermark embedding apparatus, a corresponding watermark detecting method and apparatus, and a method and system for detecting document integrity. The integrity of documents in various forms can be detected, and secret information to be hidden can be embedded therein and extracted therefrom. The techniques described are not limited to the document either in soft copy or in hard copy and have good robustness.
