  • Improving Mobile Device Security Using A Secure Execution Context
    Publication number: 20220239692
    Abstract: A device includes a secure execution context that is segregated from an operating system of the device. A security application executing in the operating system interfaces with the secure execution context to obtain verified data. The secure execution context may verify that operating system files are free of malware, obtain sensor readings that may be cryptographically signed, verify functioning of a baseband processor, and verify other aspects of the function and security of the device. The verified data may be used for various purposes such as verifying location of the device, training a machine learning model, and the like.

  • Method and System for Dynamic Patching Software Using Source Code
    Publication number: 20110126179
    Abstract: Systems and methods for extracting an original source code for an application, the original source code including source code for a function, receiving source code for a new function, the source code being a same type as the original source code, the new function to replace the function in the application, determining information from one of the original source code and an execution of the application and transforming the source code for the new function into transformed source code based on the information determined from the original source code.
