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.

摘要： Tamper-tolerant programs enable correct and continued execution despite attacks. Programs can be transformed into tamper-tolerant versions that correct effects of tampering in response to detection thereof Tamper-tolerant programs can execute alone or in conjunction with tamper resistance/prevention mechanisms such as obfuscation and encryption/decryption, among other things. In fact, the same and/or similar mechanisms can be employed to protect tamper tolerance functionality.

摘要： Implementation of software tamper resistance via integrity checks is described. In one implementation, a tamper resistance tool receives an input program code and generates a tamper-resistant program code using integrity checks. The integrity checks are generated by processing the input program code, and the integrity checks are inserted in various locations in the input program code. Values of the integrity checks are computed during program execution to determine whether a section of the program has been tampered with. Values of the integrity checks may be stored and accessed at any point during execution of the program.
摘要翻译：描述了通过完整性检查来实现软件防篡改。在一个实现中，防篡改工具接收输入程序代码，并使用完整性检查生成防篡改程序代码。完整性检查是通过处理输入程序代码生成的，并且完整性检查被插入输入程序代码中的各个位置。在程序执行期间计算完整性检查的值，以确定程序的某一节是否已被篡改。完整性检查的值可以在执行程序期间的任何时间被存储和访问。

摘要： Techniques for authenticating biometric parameters via biometric hashing are described. In one implementation, a biometric parameter of a user (e.g., fingerprint image, blood-vessel pattern, retina scan, etc.) is captured. One or more biometric hashes are produced from the biometric parameter. To generate hashes that appear random, pseudorandom metrics are applied over the biometric parameter. The hashes are stored in association with user information that can be employed to authenticate the user. Subsequently, during authentication, a new biometric parameter is captured and hashes are computed from the parameter. The new biometric hashes are then compared with the predetermined stored hashes. If any of the new hashes are found to be identical, or sufficiently similar, to one or more of the predetermined biometric hashes, the biometric parameter is deemed valid and the user is authenticated.
