US08612747B2 System and method for establishing historical usage-based hardware trust
Establishing trust according to historical usage of selected hardware involves providing a usage history for a selected client device; and extending trust to a selected user based on the user's usage history of the client device. The usage history is embodied as signed statements issued by a third party or an authentication server. The issued statement is stored either on the client device, or on an authentication server. The usage history is updated every time a user is authenticated from the selected client device. By combining the usage history with conventional user authentication, an enhanced trust level is readily established. The enhanced, hardware-based trust provided by logging on from a trusted client may eliminate the necessity of requiring secondary authentication for e-commerce and financial services transactions, and may also be used to facilitate password recovery and conflict resolution in the case of stolen passwords.

US08612371B1 Computing device and method using associative pattern memory using recognition codes for input patterns
Pattern recognition based on associative pattern memory (APM) and properties of cycles generated by finite cellular automata. APM addresses (e.g., positions in a two dimensional array) represent states. Cycles are repeating sequences of addresses. Each state is mapped to a “randomly” selected region within the input pattern. Each feature extracted from this region determines one of many next states. All next states (one for each feature type) and all sampled regions are assigned to each state randomly upon APM initialization. The process progresses from state to state, sampling regions of the pattern until the state-transition sequence repeats (generates a cycle). Each feature pattern is represented by one cycle, however different cycles can be derived from one pattern depending on the initial state. Some embodiments use a refractory period assuring a minimum cycle length, making it likely that any given pattern yields only one cycle independent of the initial state.

Furthermore, the similarity function can be defined in the n-gram space, which is equivalent to a cosine similarity in a transformed n-gram space. Locality sensitive hashing can be exploited for efficient retrieval of similar queries from a large query repository. This technique can be used to enhance the accuracy of query similarity calculation for rare queries, facilitate the retrieval of similar queries and significantly improve search relevance.
