  • Patent number: 12015695
    Abstract: A user terminal generates a first key pair and a second key pair, transmits a permission request including a public encryption key of the second key pair after electronically signing the permission request with a secret encryption key, and acquires, from permission information transmitted from a right-holder terminal, a content decryption key by using a secret decryption key of the second key pair and uses the content. The right-holder terminal stores a third key pair and the content decryption key, verifies the permission request received, and encrypts the content decryption key by using the public encryption key of the second key pair included in the permission request and transmits the permission information including the encrypted content decryption key after electronically signing the permission information with a secret encryption key of the third key pair. The permission request and the permission information are transmitted and received via a blockchain.

    Abstract: A sheet folding apparatus includes a conveyor, a first folding roller, a second folding roller, a third folding roller, a guide, a motor, and a driving force transmission mechanism. The motor causes the second folding roller to perform either forward rotation in which the second folding roller rotates to convey a sheet on a main conveying path in a conveying direction and to convey the sheet on a reflux conveying path from a joining position toward a branching position or backward rotation in a direction opposite to the forward rotation. The driving force transmission mechanism rotates the guide toward a first posture from a second posture in conjunction with the forward rotation of the second folding roller and rotates the guide from the first posture toward the second posture in conjunction with the backward rotation of the second folding roller.
