  • DEVICE, SYSTEM, AND METHOD TO GENERATE HUMAN-DISCERNIBLE INFORMATION HAVING MACHINE VERIFIABLE METADATA
    Publication number: 20250254041
    Abstract: An encoded human readable datum (EHRD) can be generated wherein the creator of the EHRD maintains control over the metadata associated with the EHRD. This metadata can be used to inform service providers how to send and receive communications with the owner of the EHRD. The metadata data associated with this EHRD can be updated. Controlling who can update the metadata associated with the EHRD is secured using cryptography, blockchain technology, or cryptography and blockchain technology.

  • Computerized apparatus and method for version control and management
    Patent number: 7805601
    Abstract: Disclosed is a computerized apparatus and method for version control and management. The apparatus includes a cryptography boot loader, a control module on key usage, and one or more agents. After the user's device is powered on, the cryptography boot loader stores a user key, and checks an operating system (OS) certificate for an OS and an application certificate for an application to determine whether these certificates are valid. Then, a right object is obtained with a user certificate through an agent. The control module on key usage compares the OS version and the application version with the version required by the right object. The permission access to the user key is determined by the comparison result. This invention associates the cryptography component with the boot loader to develop a security mechanism performed by OS and application for using a secret key.
