Abstract: Disclosed embodiments relate to implementing, as a microservice at a client, a searchable-encryption service. Operations may include executing the microservice at the client to perform operations including: encrypting data based on a cryptographic key accessible to the client; sending the encrypted data to a network storage resource; identifying, at the microservice, a search query in plaintext; encrypting the search query according to the cryptographic key; sending the encrypted search query to the network storage resource; and receiving a response to the encrypted search query from the network storage resource.

Abstract: Systems and methods for verifying human users through cognitive processes that computers cannot imitate are described herein. Human cognitive language processing techniques may be used to verify human users. Visual patterns and tests may be used to distinguish between humans and computers because computer-based visual recognition is fundamentally different from human visual processing. Persistent plugins and tests may be used to continuously verify human users.

Abstract: An apparatus providing for a secure execution environment is presented. The apparatus includes a microprocessor and a secure non-volatile memory. The microprocessor is configured to execute non-secure application programs and a secure application program, where the non-secure application programs are accessed from a system memory via a system bus, and where the secure application program is executed in a secure execution mode. The microprocessor has secure execution mode logic that is configured to monitor instructions within the secure application program, and that is configured to preclude execution of certain instructions. The secure non-volatile memory is coupled to the microprocessor via a private bus, and is configured to store the secure application program, where transactions over the private bus between the microprocessor and the secure non-volatile memory are isolated from the system bus and corresponding system bus resources within the microprocessor.
