Abstract: PURPOSE:To shorten preparation time and to simplify selection processing by evaluating whether or not there is any conflict in the adjacent relation of cells, assembling the respective cells based on the combination of cells having no conflict, and synthesizing a solid model. CONSTITUTION:Concerning the cell dividing model, in order to make a ridge line e1 existent, there are conditions that the ridge line e1 is made correspondent to a ridge line E1 of three drawings, the surfaces of any two cells among cells C1-C3 provided with the ridge line e1 cross (are not existent on the same plane) and only one cell is provided with the ridge line e1. Assuming that each cell is existent, a Boolean equation is applied as a normalizing formula so as to evaluate and calculate the combination (analysis) of assumption having no conflict. Based on the combination of cells having no conflict provided like this, the respective cells in the cell dividing model are selected and assembled, and several solid model candidates corresponding to a three-plane drawing are synthesized.

Abstract: A digital camera has means to authentication information into a photographed image for detecting the identity of the image. The authentication information supplied integrally with the image data, so that, the verifier can verify the image data without saving the authentication information. This is achieved by having a region dividing unit 24 for dividing the image into a first image region and a second image region in response to the digital signal, authentication information generating means 29 for generating authentication information from data in the first image region, encrypting means 30 for encrypting the authentication information, hiding means 25 for embedding the encrypted authentication information into the second image region by operating the data in the second image region, and region combining means 26 for combining the first image region in the image with the second image region in which the authentication information is embedded.

Abstract: The invention provides a method for accessing information on an article with a tag attached thereon, the method making it possible to prevent information on article worn by an individual from being grasped with a tag reader installed in a public space, without sacrificing traceability and without involving much increase in cost, a local server, an ONS proxy, a program, a tag creation method, a tag writer and a tag writer control program. According to the invention, there is provided a method for providing access to information on articles associated with tags in a network system including a local server, an ONS proxy, an ONS server and at least one PML server, the method comprising the steps of: the local server reading, by using a tag reader connected to the local server, the data stored in a tag including at least one encrypted virtual ID; the local server sending an ONS service request including the virtual ID to the ONS proxy; the ONS proxy acquiring an article ID by decrypting the virtual ID by use of a key K; the ONS proxy generating, by using the article ID, a network address request for acquiring the network address of a PML server in which the information on article associated with the tag is stored, to send the request to the ONS server; the local server receiving the network address of a PML server which the ONS server has returned in response to the network address request; the local server sending, by using the network address of a PML server, a PML service request including the virtual ID to the PML server; and the PML server providing access to the information on article associated with the tag, which has been specified with the article ID acquired by decrypting the virtual ID by use of the key K, for the local server.

Abstract: The invention provides a digital camera which embeds authentication informat ion for detecting the identity of a photographed image into the image. By supplying the authentication information integrally with image data, the verifier is enabl ed to verify the image data without saving the authentication information. By converting the light inputted through an optical system 21 to an electric signal, a CCD 22 outputs an anal og signal of an image. A signal processor 23 generates a digital signal of the image is r esponse to the analog signal. A digital camera has: a region dividing unit 24 for dividing the image into a first image region and a second image region in response to the digital si gnal; authentication information generator 29 for generating authentication inform ation from data in the first image region; encryptor 30 for encrypting the authentication in formation; hiding means 25 for embedding the encrypted authentication information into the sec ond image region by operating the data in the second image region; and region combinin g means 26 for combining the first image region in the image with the second image regi on in which the authentication information is embedded.
