摘要： Break-Once, Run-everywhere (BORE) resistant software configurations and digital goods and content distribution methods and arrangements are provided for use in computer systems and networks. An initial digital good is selectively divided into at least two portions. The first portion is provided to a destination computer, for example, via a CD ROM, floppy disk, or pre-loaded on a hard disk drive. The second portion is operatively modified within a source computer based on unique data associated with the destination computer. The modified second portion is then provided to the destination computer, for example, over a network, along with a key that can be used to operatively modify the first portion to be compatible with the modified second portion. The destination computer then modifies the first portion accordingly, and combines the modified first portion with the modified second portion to produce a modified digital good that is operatively different in configuration, but substantially functionally equivalent to the initial digital good. During subsequent initialization or operation, the modified digital good verifies that the destination computer is properly associated with the key and/or the unique data previously associated with the destination computer.

摘要： An implementation of a technology, described herein, for facilitating the protection computer-executable instructions, such as software. At least one implementation, described herein, may generate integrity signatures of one or more program modules—which are sets of computer-executable instructions—based upon a trace of activity during execution of such modules and/or near-replicas of such modules. With at least one implementation, described herein, the execution context of an execution instance of a program module is considered when generating the integrity signatures. With at least one implementation, described herein, a determination may be made about whether a module is unaltered by comparing integrity signatures. 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： Programs running on an open architecture, such as a personal computer, are vulnerable to inspection and modification. This is a concern as the program may include or provide access to valuable information. As a defense, the actual location of data can be hidden throughout execution of the program by way of periodic location reordering and pointer scrambling, among other things. These techniques serve to complicate static data flow analysis and dynamic data tracking thereby at least deterring program tampering.
摘要翻译：在开放架构上运行的程序（如个人计算机）易受检查和修改。这是一个问题，因为程序可能包含或提供有价值的信息。作为防御，数据的实际位置可以通过周期性位置重排序和指针加扰等方式隐藏在程序的整个执行过程中。这些技术有助于使静态数据流分析和动态数据跟踪复杂化，从而至少阻止程序篡改。

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： 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： 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.
