摘要： A secure repository individualized for a hardware environment and a method and system for providing the same. The secure repository includes a hidden cryptographic key and code that applies the key without requiring access to a copy of the key. The code that implements the secure repository is generated in a manner that is at least partly based on a hardware ID associated with the hardware environment in which the secure repository is to be installed, and may also be based on a random number. Cryptographic functions implemented by the secure repository include decryption of encrypted information and validation of cryptographically signed information. The secure repository may be coupled to an application program, which uses cryptographic services provided by the secure repository, by way of a decoupling interface that provides a common communication and authentication interface for diverse types of secure repositories. The decoupling interface may take the form of a single application programmer interface (API) usable with multiple dynamically linkable libraries.

摘要： Methods and systems for software obfuscation are disclosed. In one exemplary embodiment, the obfuscation includes integrating the checker code with product code to form integrated code. The product code includes a first portion that provides desired functionalities to a software product, while the checker code includes a second portion that protects the product code from unlicensed use. A generated pseudorandom value is used to select one or more instruction sequences of the integrated code. Following the selection, the instruction sequences may be replaced with equivalent instruction sequences to form a new integrated code. Alternatively, the original integrated code is transformed into new integrated code when the selected instruction sequences are optimized. Additionally, the new integrated code may be compared to the original integrated code by generating output states from each integrated code. The new integrated code is functionally equivalent to the original integrated code if the respective output states match.

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.

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： A watermark encoding system encodes an audio signal with both a strong and a weak watermark. The strong watermark identifies the content producer and is designed to survive all typical kinds of processing and malicious attacks. The weak watermark identifies the content as an original and is designed to be significantly removed as a result of most normal signal processing (other than A/D and D/A). The watermark encoding system has a converter to convert an audio signal into frequency and phase components and a mask processor to determine a hearing threshold for corresponding frequency components. The watermark encoding system also has a pattern generator to generate both the strong and weak watermarks and a watermark insertion unit to selectively insert either the strong or weak watermark into the audio signal. The watermark insertion unit adds the strong watermark to the audio signal when the signal exceeds the hearing threshold by a buffer value (e.g., 1–8 dB) and adds the weak watermark insertion unit when the signal falls below the hearing threshold by the buffer value. When the signal falls within the buffer area about the hearing threshold, the insertion unit takes no action. A watermark detecting system is equipped with a watermark detector that determines which block interval of the watermarked audio signal contains a watermark pattern and if the strong or weak watermark is present in that block interval of the signal.
