摘要： A memory card (110) conducts an authentication process with a server based on data stored in an authentication data hold unit (1400). The memory card (110) extracts a first session key (Ks1) from a server by a decryption process and a transaction ID from the data applied on a data bus (BS3). The memory card (110) generates a second session key (Ks2) through a session key generation unit (1418), and transmits to the server, as the keys to encrypt content data in receiving decryption of content data, the second session key (Ks2) and a key (KPm(1)) unique to the memory card (110) in an encrypted state with the first session key (Ks1). The transaction ID and the second session key (Ks2) stored in the log memory (1460) are used in the redistribution process.

摘要： An imaging unit images a subject having an unevenness pattern on a surface. The imaging unit includes: a surface light source that emits with a constant output illumination light illuminating the surface of the subject; an imager that receives reflected light reflected by the surface of the subject; and a beam splitter that is arranged at a location at which the illumination light emitted from the surface light source and the reflected light incident on the imager intersect with each other. The illumination light emitted from the surface light source is incident on the surface of the subject via the beam splitter. The reflected light reflected by the surface of the subject is incident on the imager via the beam splitter. The illumination light incident on the surface of the subject includes parallel light that is perpendicularly incident on the surface of the subject, and diffused light.

摘要： A license server (10) includes a CRL database (306) holding a revocation list recording therein classes predetermined corresponding respectively to a memory device, such as a memory card, and a content reproduction circuit, such as a cellular phone, that are subjected to revocation of distributing, reproducing and transferring content data. A distribution control unit (315) suspends an operation distributing content data if the distribution is addressed to a class listed on the revocation list. The revocation list is also held in the memory card and distribution control unit (315) in distributing content also transmits information for updating the revocation list in the memory card.
