摘要： According to embodiments of the invention, a system, method and computer program product for a computer program product for marking and acquiring sought after content are provided. Embodiments include a method comprising inserting a first desired content ID for a desired content item in a content directory for a first device in a network of media devices. The content directories of the devices in the network include content IDs of content present in the device, and also content IDs of content desired for the devices. Content directories of the other devices in the network are compared to determine if any of the other devices have a content directory containing the first desired content ID. For devices having the first desired content ID in its content directory, a determination is made of whether the desired content is present in the other device, and if the desired content is present in the other device, a copy of the desired content is transferred to the first device.

摘要： Disclosed herein are methods, systems, and computer-readable storage media for annotation driven integrity program verification. The method includes distributing verification calls configured to verify a function across call paths leading to the function in source code, generating a binary from the source code having placeholders associated with the verification calls, and filling each placeholder in the binary with verification data or reference checksums. Alternatively, the method includes receiving source code having a verification call, replacing the verification call with one or more equivalent verification calls distributed over a call path, replacing each verification call with a checksum function generating placeholders while compiling, generating a binary based on the placeholders, and filling each placeholder in the binary with reference checksums. The system includes a processor and a module controlling the processor to perform the methods. The computer-readable storage medium includes instructions for controlling a computer to perform the methods.

摘要： Disclosed herein are systems, methods, and computer-readable storage media for obfuscating software data references. The obfuscation process locates pointers to data within source code and loads the pointers into an ordered set of pools. The process further shuffles the pointers in the ordered set of pools and adds a function within the source code that when executed uses the ordered set of pools to retrieve the data. The obfuscation process utilizes pool entry shuffling, pool chaining shuffling and cross-pointer shuffling.

摘要： Disclosed herein are systems, methods, and computer readable-media for obfuscating code through conditional expansion obfuscation. The method includes identifying a conditional expression in a computer program, identifying a sequence of conditional expressions that is semantically equivalent to the conditional expression, and replacing the conditional expression with the semantically equivalent sequence of conditional expressions. One option replaces each like conditional expression in the computer program with a diverse set of sequences of semantically equivalent conditional expressions. A second option rearranges computer instructions that are to be processed after the sequence of conditional expression is evaluated so that a portion of the instructions is performed before the entire sequence of conditional expressions is evaluated. A third option performs conditional expansion obfuscation of a conditional statement in combination with branch extraction obfuscation.

摘要： Disclosed herein are systems, methods, and computer-readable storage media for obfuscating by a common function. A system configured to practice the method identifies a set of functions in source code, generates a transformed set of functions by transforming each function of the set of functions to accept a uniform set of arguments and return a uniform type, and merges the transformed set of functions into a single recursive function. The single recursive function can allocate memory in the heap. The stack can contain a pointer to the allocated memory in the heap. The single recursive function can include instructions for creating and explicitly managing a virtual stack in the heap. The virtual stack can emulate what would happen to the real stack if one of the set of functions was called. The system can further compile the source code including the single recursive function.
摘要翻译：本文公开了用于通过共同功能进行混淆的系统，方法和计算机可读存储介质。被配置为实施该方法的系统识别源代码中的一组函数，通过将函数集合的每个函数变换为接受统一的参数集合并返回统一类型来生成变换的函数集合，并且将经变换的集合函数转换为单个递归函数。单个递归函数可以在堆中分配内存。堆栈可以包含指向堆中分配的内存的指针。单个递归函数可以包括用于创建和显式管理堆中的虚拟堆栈的说明。如果调用了一组函数，虚拟堆栈可以模拟真实堆栈将会发生什么。该系统可以进一步编译包含单个递归函数的源代码。

摘要： Disclosed herein are systems, computer-implemented methods, and computer-readable storage media for call path enforcement. The method includes tracking, during run-time, a run-time call order for a series of function calls in a software program, and when executing a protected function call during run-time, allowing or causing proper execution of a protected function call only if the run-time call order matches a predetermined order. The predetermined order can be an expected run-time call order based on a programmed order of function calls in the software program. The method can include maintaining an evolving value associated with the run-time call order and calling the protected function by passing the evolving value and function parameters corrupted based on the evolving value. The protected function uncorrupts the corrupted parameters based on the passed evolving value and an expected predetermined call order. A buffer containing the uncorrupted parameters can replace the corrupted parameters.

摘要： A system, method, and computer program product for preventing a malicious user from analyzing and modifying software content. The one-way functions used in prior art systems using dynamically evolving audit logs or self-modifying applications are replaced with a one-way function based on group theory. With this modification, untampered key evolution will occur inside a defined mathematical group such that all valid key values form a subgroup. However, if the program is altered, the key will evolve incorrectly and will no longer be a member of the subgroup. Once the key value is outside of the subgroup, it is not possible to return it to the subgroup. The present invention provides a limited total number of valid keys. The key evolution points are not restricted to locations along the deterministic path, so the key can be used in various novel ways to regulate the program's behavior, including in non-deterministic execution paths.
摘要翻译：一种用于防止恶意用户分析和修改软件内容的系统，方法和计算机程序产品。使用动态演进的审计日志或自修改应用程序的现有技术系统中使用的单向函数被基于组理论的单向函数所取代。通过这种修改，无限制的密钥演进将发生在定义的数学组内，使得所有有效的密钥值形成一个子组。但是，如果程序被更改，则密钥将不正确地发展，不再是该子组的成员。一旦键值超出了子组，就不可能将其返回到子组。本发明提供了有限的总数量的有效密钥。关键演化点不仅限于确定路径上的位置，所以密钥可以以各种新颖的方式用于调节程序的行为，包括在非确定性执行路径中。
