    摘要： An object is to achieve both the safety and convenience in authentication of an object to be authenticated which is required in various situations. An authentication system (900) includes a first authentication information transmitting device (901) having first authentication information, a second authentication information transmitting device (904) having second authentication information, and an authentication section (905) for authenticating a user or authority of the user. The second authentication information transmitting device (904) sends the second authentication information in only a period during which it receives the first authentication information sent from the first authentication information transmitting device (901). The authentication section (905) receives the second authentication information sent from the second authentication information transmitting device (904), and authenticates the user or the authority of the user based on the second authentication information.

    摘要： An optical disc recording apparatus (10) is provided with a tracking servo (13) for tracking a spiral track of concave and convex marks, an analog signal processor (14) for extracting a reproduction signal corresponding to the concave and convex marks, a digital signal processor (15) for extracting a channel clock synchronized with a channel bit length of the concave and convex marks, and a sub-information recording section (30) for recording sub-information by irradiating laser light based on the tracking to the spiral track. The sub-information recording section (30) records all the sub-information by repeating a process of recording a part of the sub-information by discretely irradiating laser light at a specified interval and with a specified frequency in synchronism with a channel clock by one tracking to form recordable marks on a reflective film a plurality of times. By this construction, a tracking control to the concave and convex marks can be stably executed and the sub-information can be stably recorded.

    摘要： A management server has: an identification-information reproducing unit which reproduces identification information from an optical disk; an invalid-unit intrinsic-information registration section which registers the reproduced identification information; and a restriction-lifting decision section which decides, on the basis of the registered identification information and unit intrinsic information given intrinsically to every recording unit, whether the identification information can be recorded on a master optical disk. A recording unit has: a communication section which notifies the management server of the unit intrinsic information on this recording unit; an identification-information generation section which generates the identification information recorded on the master optical disk; an identification-information recording section which records the identification information on the master optical disk; and a restriction lifting section which controls the operation of the identification-information generation section and the identification-information recording section on the basis of the decision result of the restriction-lifting decision section.

    摘要： On an optical disc, main information to be decrypted using sub information is recorded by arranging concave or convex recording marks in a spiral track and a reflective film is formed on the recording marks. First sub information is recorded as being superimposed on the main information by shifting or deforming the recording marks or altering a pattern of the recording marks. Second sub information is recorded as being superimposed on the main information by changing a reflectivity of the reflective film formed on the recording marks. The first sub information and the second sub information are recorded in an area from which the first sub information and the second sub information are to be read simultaneously. The second sub information is recorded in a manner that the second sub information is associated with the first sub information. The first sub information and the second sub information are associated with each other, and improve resistance to unauthorized copying by prohibiting content information from being read unless both the first sub information and the second sub information are read. The first sub information and the second sub information are recorded in the same area, and prevent the time taken for reading sub information from increasing.

    摘要： An information recording device, an information reproducing device, and an information recording medium securely protect copyright of main information, and prevent illegal access to the recorded main information. The information recording device includes a medium unique information generating section that generates second sub information by data-converting stamper unique information based on disc identification information that differs for each optical disc after transferring main information and first sub information from a stamper having the main information and the first sub information recorded thereon onto an optical disc, and a medium unique information recording section that records the second sub information on the optical disc having recorded thereon in advance the main information and the first sub information in a form different from the forms of the main information and the first sub information.
