摘要： A state store having state information therein is stored on a computing device. Information at least nearly unique to the computing device is obtained, and a number of locations at which at least a portion of the state store is to be stored at is determined. Pseudo-random file names and corresponding paths are generated based at least in part on the obtained information, whereby the generated file names and corresponding paths are likewise at least nearly unique to the computing device, and the generated file names and path are paired to form the locations. Thereafter, the state store is stored according to the generated locations.

摘要： A security flag stored in a trusted store is utilized to determine if the trusted store has been subjected to tampering. The security flag is indicative of a globally unique identifier (GUID), the version of the trusted store, and a counter. The security flag is created when the trusted store is created. Each time a critical event occurs, the security flag is updated to indicate the occurrence thereof. The security flag also is stored in a write-once portion of the system registry. At appropriate times, the security flag stored in the trusted store is compared with the corresponding security flag stored in the write-once registry. If the security flags match within a predetermined tolerance, it is determined that the trusted store has not been subjected to tampering. If the security flags do not match, or if a security flag is missing, it is determined that the trusted store has been subjected to tampering.
摘要翻译：使用存储在可信存储中的安全标志来确定可信存储是否已经被篡改。安全标志指示全局唯一标识符（GUID），可信存储的版本和计数器。创建可信存储时创建安全标志。每当发生紧急事件时，安全标志被更新以指示其发生。安全标志也存储在系统注册表的一次写入部分中。在适当的时间，将存储在可信存储中的安全标志与存储在一次写入注册表中的对应的安全标志进行比较。如果安全标志在预定公差内匹配，则确定可信存储没有遭受篡改。如果安全标志不匹配，或者如果安全标志丢失，则确定可信存储已经受到篡改。

摘要： A first process operating on a computer comprises code to be executed in connection therewith, where the code includes at least one triggering device. A digital license corresponds to the first process and sets forth terms and conditions for operating the first process. A second process operating on the computer proxy-executes code corresponding to each triggering device of the first process on behalf of such first process. The second process includes a selection of options to thwart reverse engineering by a debugger if a debugger is detected. The options include execution by a proxy engine of a re-routed call, crashing the first process, detection ad elimination of a debugger related interrupt a call to an arbitrary function.
摘要翻译：在计算机上操作的第一进程包括要与其一起执行的代码，其中代码包括至少一个触发设备。数字许可证对应于第一个进程，并列出了操作第一个进程的条款和条件。在计算机代理上操作的第二进程代表第一进程执行对应于第一进程的每个触发装置的代码。如果检测到调试器，第二个过程包括一些选项来阻止调试器的逆向工程。选项包括代理引擎执行重新路由呼叫，崩溃第一个进程，检测广告消除调试器相关中断对任意函数的调用。
