  • Publication number: 20170092170
    Abstract: A magnetic scanning method includes acquiring an image from a storage device of a magnetic scanning device, controlling a magnetic read-write head of the magnetic scanning device to touch a reference point on a plane, generating an electric signal which reflects relevant information of the acquired image, inputting the electric signal reflecting the relevant information of the acquired image to the magnetic read-write head, when the electric signal reflecting the relevant information of the acquired image flows through the magnetic read-write head, controlling the magnetic read-write head to generate a magnetic field corresponding to the electric signal, controlling the magnetic read-write head to move and scan the plane from the reference point, to magnetize the magnetic powder on the plane by the magnetic field, and driving the magnetic powder to move relatively to generate an image similar to the acquired image.

  • Publication number: 20170093816
    Abstract: A remote encryption method is executed by at least one processor of a cryptographic center. The cryptographic center connects to a sending end and to at least one receiving end. Data and a list listing at least one receiving end to which the data is to be sent are received from the sending end. A public key corresponding to the at least one receiving end listed in the received list is obtained. The received data is asymmetrically encrypted using the obtained public key corresponding to the at least one receiving end. The encrypted data is sent to the corresponding receiving end.

  • Publication number: 20160323100
    Abstract: A key generation device generates an initial secret key, and a time update key at regular intervals, and transmits the initial secret key and the time update key to a terminal device. The terminal device utilizes the initial secret key, the time update key, and a private key generated by the terminal device itself to form a key group. The key group and a public key generated by the terminal device are used as a key pair to encrypt and decrypt data, give a digital signature, and verify digital signatures. The time update key includes a time period, and after the time period expires the time update key cannot be used by the terminal device to generate the key group. A data signature and encryption method is also provided.
