Benefits of technology

The patent text describes an image processing apparatus that can determine if a manuscript is the original by using a paper fingerprint and document information acquired from the same paper form. The apparatus generates an encoded image that is used to acquire the paper fingerprint and document information. The technical effect of this invention is to provide a reliable way to verify the identity of a manuscript and ensure that it is the original.

Problems solved by technology

However, although the technique disclosed in Japanese Patent Laid-Open No. 2004-112644 can determine identity of the paper form with the help of the paper fingerprint, it cannot be determined whether the printed matter is an original.
The reason of this is that the identity of the document information cannot be guaranteed.
The reason of this is that the identity of the paper form cannot be guaranteed.

first embodiment

[0044]

[0045]FIG. 1 is a block diagram showing an image processing system according to the present invention. Although in this diagram, in order to illustrate the system, one host computer 40 and three image formation apparatuses 10, 20, and 30 are connected to a LAN 50, the number of these elements is not limited to these numbers in the image processing system according to the present invention. Moreover, although the LAN is applied to this embodiment as a connection method, the connection method is not limited to this. For example, an arbitrary network, such as WAN, can also be applied. Furthermore, serial transmission systems, such as US, and parallel transmission systems, such as Centronics and SCSI, are applicable to this image processing system.

[0046]The host computer (hereinafter referred to as PC) 40 has functions of a personal computer. This PC 40 can transmit and receive a file using the FTP or SMB protocol through the LAN 50 or WAN. Moreover, the PC 40 can issue a print in...

second embodiment

[0162]In the first embodiment, the embodiment where the image formation apparatus 10 displays the collation processing and the result of collation. However, the above-mentioned collation processing and the results of collation may be displayed on the PC 40.

third embodiment

[0163]The document that serves as the original(The document that is to be the original) may occasionally suffer additional writing because of human carelessness. In such a case, the authenticity guarantee by the method described in the first embodiment determines that the document is tampered because of inconsistency in the document information. This leads to a situation where there is not an original at all in the world.

[0164]In view of this, in this embodiment, only if it is determined that there is a possibility of the document being tampered, reissue of the original becomes possible upon user's request of reissue of the original (namely, the original is newly reissued). By the reissue, the following two data are synthesized: encoded image data whose document information is the same as the original, but only whose paper fingerprint information is updated; and image data of the former original that was regenerated from the decoded data. Then, a printed matter on which the authenti...

Abstract

According to the present invention, authenticities of paper fingerprint information and of document information are collectively determined through formation of an original that is given an encoded image in which both paper fingerprint information and document information are encoded. By collectively guaranteeing identities of the paper form and of the document, it becomes possible to realize the more reliable authenticity guarantee.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to an image processing apparatus, an image processing method, and a storage medium that can handle a paper fingerprint.[0003]2. Description of the Related Art[0004]In recent years, it has become possible to duplicate securities and certificate papers that cannot be distinguished from originals. Moreover, on the other hand, there are increasing scenes in which the contents of the securities and certificate documents are made electronic and they are printed and allowed to be used. That is, needs and opportunities of guaranteeing authenticities of documents are increasing.[0005]Japanese Patent Laid-Open No. 2004-112644 discloses an identity assurance technique of a paper form by means of a paper fingerprint. A technique disclosed in Japanese Patent Laid-Open No. 2004-112644 is to add a mark on the paper form and read a paper fingerprint of the paper form using the mark as a reference. Further, the re...
