摘要： A method, apparatus, and article of manufacture for providing secure and opaque type libraries to automatically provide secure variables within a programming module. A system for providing secure and opaque type libraries to automatically provide secure variables within a programming module. The system includes an OTL selection module, an OTL substitution module, an OTL type library database, a compiler module; and a linker module to create an executable processing module. The OTL selection module randomly selects or generates one of the possible variable obfuscation functions for each declared secure variable. The OTL substitution module substitutes the separate instance of the selected variable obfuscation function for every reference to the declared secure variable. The OTL type library database receives queries from the OTL selection module a database to identify of possible variable obfuscation functions applicable for the variable type corresponding to the declared secure variables.

摘要： A digital rights management (DRM) distribution architecture produces and distributes digital goods (e.g., software, audio, video, and other content) in a fashion that renders the digital goods resistant to many known forms of attacks. The DRM distribution architecture protects digital goods by automatically and randomly manipulating portions of the code using multiple protection techniques. Applying a mixture protection techniques in random fashion makes it extremely difficult for pirates to create illicit copies that go undetected as legitimate copies. In addition, the architecture also supports a quantitative unit that allows a producer to specify how much protection may be added to the digital good.

摘要： A computer-implemented system and method for configuring and operating a white-box cipher is disclosed. In one implementation, the system employs a method for configuring pseudorandom data derived from a key to perform key-scheduling functionality associated with rounds of the cipher. Additionally, the system employs a method for generating white-box executable code, wherein the code hides the pseudorandom data by incorporating it into mathematical operations performed during execution of the rounds. Accordingly, the cipher is suited for white-box applications managing digital rights, such as decoding audio, video and other content.

摘要： Implementation of graph-based tamper resistance modeling for software protection is described. In one implementation, paths of execution of a program are modeled as a graph having nodes and edges. A tamper resistance tool receives an input program code corresponding to the program and generates a tamper-resistant program code using integrity checks. Values for the integrity checks are computed during program execution and are compared to pre-computed values to determine whether a section of the program has been tempered with. Values of the integrity checks may be accessed at any point in time during execution of the program.

摘要： Cyclic verification of code integrity is applied to an object by identifying multiple segments of the object. Each segment is separated into multiple blocks, and a message authentication code (MAC) value of each of these segments is computed. The computed module MAC values are then incorporated into selected ones of the multiple segments (referred to here as “checker segments”), which may also have their MAC values incorporated into other checker segments. A new MAC value for each of the checker segments is then calculated. A new block is added to each of the checker segments that results in restoring the MAC value of the checker segment back to its original value. Thus, the checker segments can be subsequently verified based on the MAC values stored in other segments.

摘要： An implementation of a technology is described herein for deriving robust non-local characteristics and quantizing such characteristics for blind watermarking of a digital good. This technology finds the proper balance between minimizing the probability of false alarms (i.e., detecting a non-existent watermark) and the probability of misses (i.e., failing to detect an existing watermark). The technology, described herein, performs quantization index modulation (QIM) based upon non-local characteristics of the digital good. Non-local characteristics may include statistics (e.g., averages, median) of a group of individual parts (e.g., pixels) of a digital good. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
