摘要:
The present invention provides a document verification system capable of verifying whether a document is an original at low cost and with ease. A terminal device acquires, as a registered feature vector feature information indicating a feature of a nonreproducible disorder portion in a printing region on a document serving as the original, and stores the registered feature vector on a hard disk via the Internet. A server acquires, as a calculated feature vector the same information as the registered feature vector in a document to be verified as to whether the document is the original, reads out the registered feature vector from the hard disk, compares the acquired calculated feature vector with the read out registered feature vector, and verifies whether the document to be verified is the original on the basis of a result of the comparison.

An authenticity determination method and an apparatus for determining the authenticity of solid object having a random and readable intrinsic characteristic distributed on the surface thereof are disclosed. In this method and apparatus, reference data expressing the characteristic distributed on the genuine solid object are acquired, and cross-checking data expressing the characteristic distributed on the solid object to be determined for authenticity are derived. Further, on the basis of the reference data and the cross-checking data, correlation values of data expressing the characteristic distributed on either the genuine solid object or the solid objects to be determined for authenticity, with data expressing the characteristic distributed on the other solid object are calculated, and authenticity of the solid object to be determined for authenticity is determined on the basis of the maximum value of the correlation values obtained by the calculation and a characteristic quantity that expresses the shape of the distribution of correlation values obtained by repeating this calculation.

The present invention provides a detection apparatus, an input apparatus, an individual identification apparatus, and a recording medium that utilize information about users' bodies which disables the fraud of impersonating authorized users and is extremely difficult to forge and is obtained without giving the users a sense of inhibitions, without restraining their bodies during use, and independent of their mental states and health. A FIFO memory outputs, as one set of features, a total of 60 voltage values, which are broken down as 20 voltage values sampled every 12.5 ms (80 Hz) before the instant when timing is inputted at the peak position of an amplitude waveform signal generated by one click operation, 39 voltage values sampled every 12.5 ms after the instant, and a voltage value at the peak, and a CPU calculates a feature vector and a feature matrix for individual registration, stores them as personal data in a RAM, and identifies one set of features newly inputted, based on the personal data stored in the RAM.

A three-dimensional object identifying system is disclosed which identifies a three-dimensional shape object optically such as a part of a human body for preventing an information apparatus such as a personal computer from being used by any other illegitimate user than a legitimate user. The three-dimensional object identifying system has a function generating unit which generates modulation signals, light emitting elements which emit lights based on the modulation signals to a three-dimensional object, light receiving elements which receive reflected lights from the three-dimensional object and which produce detection signals, a correlation detecting unit which detects correlation information between each detection signal and modulation signal, and an identifying unit which performs identifying processing for the three-dimensional object on the basis of both pre-cataloged correlation information and the detected correlation information.

摘要:
The present invention provides a surface-reading apparatus that includes a subject-flexing mechanism and a surface-reading component. The subject-flexing mechanism causes a subject to flex in one of a convex form and a concave form. The surface-reading component reads a characteristic of a surface condition of the subject that has been flexed by the subject-flexing mechanism. The surface-reading component can includes an optical reading component that optically reads the characteristic of the surface condition of the subject. The optical reading component may be a reflected light-reading component that reads the characteristic of the surface condition of the subject with reflected light or may be a transmitted light-reading component that reads the characteristic of the surface condition of the subject with transmitted light.
