Abstract: An IC card includes a first visible layer including a natural material having a unique visual pattern. A storage device is configured to store a digital reference image of the unique visual pattern to be visually compared with the unique visual pattern for authentication. An authentication method based on the IC card is also provided.

Abstract: A device for assigning a geographical position to a picture may include a photo camera module for taking the picture, a satellite positioning system receiver module for identifying geographical coordinates when the picture is taken, and a cryptographic module to sign the picture and the corresponding geographical coordinates. The device may store the signed picture and the corresponding geographical coordinates as certified geographical position of the picture.

Abstract: An IC card includes a first visible layer comprising a nonmetallic natural material having a physical structure including a unique visual pattern. The IC card further includes a storage device configured to store a reference image of the unique visual pattern. The reference image is a scan of the unique visual pattern. The reference image is configured to be visually compared with the unique visual pattern for authentication. A second layer is included on a bottom surface of the first visible layer. The first visible layer and the second layer are laminated together. Each of the second layer and the nonmetallic natural material of the first visible layer have a same size to define a shape of the IC card.

Abstract: A microprocessor of a solid state memory protects the contents of the solid state memory by comparing a sequence of requests for access to physical blocks of the solid state memory with a predetermined sequence of requests to verify the sequence of requests, and by responding to additional requests for access to the physical blocks of the solid state memory to decrypt and transfer requested files stored therein when the sequence of requests equals the predetermined sequence of requests, thereby verifying the sequence of requests. The predetermined sequence of requests is associated with a plurality of virtual files that can be selected, in a particular sequence, to simulate a request for access to physical blocks of the solid state memory, while the predetermined sequence of requests is stored in a configuration file of the solid state memory in correspondence with an identifier of additional protected files.
