  • Patent number: 10833859
    Abstract: A encrypted verification system and method includes detecting an attempt to access a service requiring multi-factor authentication from a first user computing device, requesting a trusted platform module (TPM) public key of a second user computing device, the second user computing device being coupled to the first user computing device, generating a nonce in response to receiving the TPM public key of the second user computing device, sending the nonce for signature by a TPM private key of the second user computing device, receiving a signed nonce, wherein the signed nonce is signed by the TPM private key and decrypted using the TPM public key of the second user computing device, and determining that a value of the signed nonce matches a value of the nonce to authenticate the first user computing device and allowing access to the service.
    Type: Grant

  • Patent number: 10152604
    Abstract: An Attestation Identity Key pair (AIK pair) is created from a hardware identifier of a hardware machine and a geographical location. the AIK pair includes a private AIK and a public AIK. The public AIK and the geographical location are stored in a repository. the public AIK is matched with a key used to sign a data request. A geographical restriction policy corresponding to the geographical location associated with the public AIK is executed. When the geographical restriction policy determines that a type of the data request corresponds to an authorized request type from the geographical location, a service is instructed to process the data request.
