摘要： Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. The watermark extraction results can be stored in a secure location and accessed by other devices at different times. These operations can be conducted by one or more trusted devices that reside in a home network. The home network can also include a gateway device that can coordinate the operations of the various network devices and/or delegate the various watermark extraction and content screening operations.

摘要： Techniques for making and using recoverable marks for films. The recoverable mark consists of a portion of a film to which a watermark that is imperceptible to viewers of the film has been applied and an original mark that is applied to the portion of the film with the watermark. Application of the original mark to the portion modifies the watermark, and consequently, if the original mark is altered, the modifications to the watermark preserve the original mark. In one application of the technique, the watermark is applied to a digital master of the film, a master analog copy is made from the digital master, and a unique original mark is applied to each of the copies made from the master analog copy.

摘要： Improved techniques for making copy detection patterns and using them to detect copying relationships between digital representations. The techniques include techniques for including a message in a copy detection pattern without altering the copy detection patterns entropy and reading the message, techniques for using a copy detection pattern on an analog form to determine whether the analog form is an original analog form without reference to a digital representation of the original of the analog form's copy detection pattern, techniques for increasing the sensitivity of copy detection using copy detection patterns by modifying one of two copy detection patterns that are being compared to take into account alterations resulting from the copying process, techniques for distributing a copy detection pattern across a document, and techniques for using the entropy of a copy detection pattern to locate the copy detection pattern. Also disclosed are applications of copy detection patterns with copying that involves transformations between the digital and analog forms and with digital-to-digital copying.

摘要： Techniques for using a class loader to protect mobile code against a malicious host. The techniques include using the class loader to extend a class used by the mobile code such that a method is added to the code which authenticates the mobile code. When executed, the method provides a dynamic watermark that authenticates the code. The method may be encrypted until it is added to the code. One such method uses a static watermark in the code to determine whether the code has been modified.The techniques also include using a class loader to extend the class such that obfuscated symbolic names in the program that correspond to symbolic names defined by the class can be resolved. A way of doing this is to include a first association between the obfuscated symbolic names and encrypted forms of the corresponding symbolic names in the program and to make a second association between the encrypted forms of the corresponding symbolic names and information used to resolve the symbolic names defined in the class. The loader then uses the first and second associations to resolve the obfuscated names.The class extension techniques may be combined with obfuscation of names defined in the program and static watermarking to provide layered protection of the mobile code. The obfuscation and definition of the first association are done prior to execution of the program and the class extension is done on execution of the program. The disclosed techniques are particularly well-adapted for use with the byte codes produced by Java language compilers from Java language programs.
