Abstract: An apparatus comprises a memory communicatively coupled to a processor. The memory is configured to store smart card feedback, multiple graph analyzer operations, and multiple smart card identifiers (ID). Each smart card ID indicates the one or more smart cards associated with a corresponding user. The processor is configured to receive smart card feedback associated with a smart card ID, derive multiple interactions in an environment based at least in part upon the smart card feedback, generate an intelligent pattern based at least in part upon the interactions, assign multiple adverse impacts to the intelligent pattern, generate multiple suggestions configured to mitigate the adverse impacts, and execute the graph analyzer operations to determine whether the suggestions mitigate the adverse impacts. Further, the processor is configured to generate a report relating the suggestions to the environment in response to determining that the suggestions mitigate the adverse impacts.

Abstract: This disclosure describes hardware-based mutexes that employ software process authentication to prevent a software process from releasing the lock of a mutex locked by another software process. For example, systems are described in which a mutex controller receives a request from a process to lock a mutex. The mutex controller locks the mutex, writing a process key and process identifier to one or more hardware registers associated with the mutex. If the mutex controller receives a request to release the lock on the mutex, the mutex controller determines if the key received with the request matches the process key written in the one or more hardware registers of the mutex and, if so, releases the lock on the mutex.
