An amorphous alloy member including an irregular region having a center line average roughness Ra of about 0.1 μm to about 1000 μm on a surface, at least the irregular region including an amorphous alloy having an amorphous phase at a volume ratio of about 50% to about 100%. A process for manufacturing the amorphous alloy member, and an authenticity determination device and an authenticity determination method using the amorphous alloy member.
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.
摘要:
A method of creating a tag, the method including: reading, over a first region of a surface of an individual piece, a characteristic having randomness distributed over the surface of the individual piece and converting image information indicative of the read characteristic of the first region into individual piece information peculiar to the individual piece; forming an individual piece information image indicative of the individual piece information on the surface of the individual piece while using a second region having a predetermined range including the first region as a non-image forming region; and creating the tag, which is to be affixed to an article, from the individual piece.

摘要:
A certification information generating apparatus includes: a feature quantity generator, for generating a feature quantity related to a paper medium on which identification information is printed; and a database generator, for generating a database wherein the feature quantity and the identification information are correlated with each other. The database that is generated is employed for a predetermined process related to certification of a paper medium.
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.
