  • Patent number: 9235947
    Abstract: A subject discriminating apparatus discriminates a subject having an unevenness pattern on a surface of the subject. The subject discriminating apparatus includes: a transparent unit including a supporting surface supporting the subject; a light irradiation unit irradiating illumination light onto the surface of the subject through the transparent unit; an imaging unit imaging an imaging region including at least a part of the transparent unit, and generating image data; and a discrimination processing unit discriminating the subject, using the image data generated by the imaging unit. The discrimination processing unit discriminates the subject based on discrimination image data generated by correcting subject image data using correction image data. The subject image data is generated by imaging the imaging region in a state of the subject presenting in the imaging region. The correction image data is generated by imaging the imaging region free from the subject in the imaging region.

  • Patent number: 8561776
    Abstract: 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.

  • Patent number: 7945517
    Abstract: A memory card (110) stores access restriction information (AC1) to a license information hold unit (1440) arranged in a TRM area. Access restriction information (AC1) has information for example of a frequency of reproduction allowed and a number of licenses owned. A controller (1420) in reproducing and transferring content initially confirms access restriction information (AC1) and thereafter effects reproduction and transfer and after the reproduction and transfer are effected updates access restriction information (AC1), as required, for storage in a license information hold unit (1440).

  • Patent number: 7340055
    Abstract: 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.

  • Publication number: 20050120232
    Abstract: A hard disk (530) of a personal computer has a content list file (150) and an encrypted private file (162). A license administration device (520) stores a binding key Kb in a license region (5215B) of a memory. The encrypted private file (162) can be decrypted and encrypted with the binding key Kb stored in the license administration device (520). The license of the obtained and encrypted content data is stored as private information in the encrypted private file (162). Consequently, the encrypted content data and the license distributed by software can be shifted to another data terminal device.

  • Publication number: 20050076208
    Abstract: A personal computer 50 holds encrypted contents data and a license acquired from a distribution server (10) over an Internet network (30) or from a music CD (60) using a CD-ROM drive. The personal computer (50), which is connected to a portable reproduction terminal (100) through a USB cable (70), performs a checkout operation for lending out, the encrypted contents data and the license to a memory card (110) attached to the portable reproduction terminal (100), and a checkin operation for returning the lent encrypted contents data and the lent license. As a result, it is possible to shift the encrypted contents data and the license acquired by software to the other device.
