Abstract:
In order to cancel an offset caused by a variation of a signal inputted from an optical pickup, variations of elements in an integrated circuit, etc., a calibration circuit which generates and feeds back an offset adjustment amount that makes the offset zero by a comparison with a reference value, and an offset adjustment circuit that makes the offset zero using the fed-back control signal are provided in an analog front-end LSI. The offset adjustment by the calibration circuit is automatically done in response to commands supplied from a digital signal processing LSI, a host control device, etc. On the other hand, as for a signal on which arithmetic processing such as gain control, addition and subtraction, is performed, the offset adjustment is performed by sending the offset adjustment amount obtained by an arithmetic operation performed by software processing of the digital signal processing LSI to the analog front-end.

Abstract:
The pattern (pattern characteristic quantity) extracted from the pattern image carried by original printing paper is stored on the original printing paper and the validity of the original printing paper is verified according to the pattern stored on code-added printing paper at the time of copying the printed contents of the code-added printing paper so as to determine if the code-added printing paper is truly original or not by means of the pattern carried by the printing paper itself. Therefore, it is possible to prevent unauthorized copying with ease without using any special paper and hence appropriately protect the printed contents.
Abstract:
The present invention allows a device to easily generate pseudorandom numbers using information about a living body. An imaging element outputs an image signal equivalent to imaging light reflecting a target of identification inside a certain part of a living body. The device extracts data from the image signal output from the imaging element. This data reflects a change arising from the living body and a change of the imaging element. The device then generates a pseudorandom number using the data as a seed. Specifically, to produce the seed, the device sequentially selects two image signals output from the imaging element as a pair, sequentially detects difference between the pair of image signals, recognizes one of the detected differences as criterion, and then calculates a degree of difference between the criterion and the rest of differences.

Abstract:
There is provided a biometric authentication system including a plurality of information processing devices divided to a first group for performing a primary authentication based on feature quantity information unique to a biological pattern of a user associated with biological information, and specifying an identification number assigned to the user, and a second group for performing a secondary authentication on the biological information that succeeded in the primary authentication based on the identification number and registered biological information registered in advance. The input biological information is transmitted to all information processing devices belonging to the first group, the biological information that succeeded in the primary authentication is added as queuing information to a queue, and each of the information processing devices belonging to the second group acquires the queuing information positioned at a head of the queue when the secondary authentication process being executed in the own device is terminated.
Abstract:
The present invention relates to a single-chain circular RNA having a sustained or slow-releasing RNA interference effect, characterized in that the single-chain circular RNA comprises a sense strand sequence, an antisense strand sequence complementary to the sense strand sequence, identical or different two loop sequences between the sense strand and the antisense strand, connecting both strands, wherein the sense strand and the antisense strand are paired to form a stem.
Abstract:
To propose an information extracting method, a registration device, a verification device, and a program for improving the authentication accuracy while suppressing the amount of information of an identification target. From a plurality of images having viewpoints in a biological body portion environment, common portions of the silhouette of a biological body portion shown in the images are generated as a stereogram in a target space, and values representing shapes of a plurality of cross-sections of the stereogram, the plurality of cross-sections each having a predetermined positional relationship with a reference position of the stereogram, are extracted as identification information. The stereogram can be represented in a discrete manner since the identification data is extracted as data representing cross-sections each having a certain relationship with a reference position in an outer shape of the stereogram as well as cross-sections of portions of the stereogram of the biological body portion.
