Image reading apparatus, image forming apparatus, image processing system and image reading method

Abstract

An image reading apparatus, which has reading means for reading images recorded on sheets and carries out predetermined processing for the images read using the reading means, comprising first extracting means for extracting a plurality of predetermined patterns from the images read using the reading means, second extracting means for extracting the combination information regarding the combination of the patterns from the images read using the reading means, and judging means for judging whether the combination of a plurality of the patterns extracted using the first extracting means coincides with the combination information extracted using the second extracting means or not, the predetermined processing being carried out on the basis of the result of the judgment made using the judging means.

Description

technical field [0001] The present invention relates to an image reading device capable of user authentication, function setting of the device, and removal of restrictions on the function of the device using the front and back sides of a sheet or using a combination of a plurality of sheets , relates to an image processing system having an image reading device, relates to an image forming device capable of generating paper for the image reading device and the image processing system, and relates to an image reading method. Background technique [0002] In recent years, a user interface such as a touch panel has been increasingly used for user authentication. For example, user authentication is performed in the following cases: data read using an image reading device such as a scanner is printed using an image forming device such as a printer or a digital multifunction device; The read data is stored in a printer or the hard disk drive of a digital multifunction device, and ...

Problems solved by technology

[0005] However, the device disclosed in Japanese Laid-Open Patent Application No. 2003-345760 needs to be provided separately from a barcode reader for reading barcodes

Also, in the case where the number of barcodes to be read is large, the order of reading barcodes becomes complicated, and the burden on the user increases

In the case of a small number of barcodes, the device is still problematic because of the danger that a third party may read the barcode by trial or error and be certified

[0006] Also, although the device disclosed in Japanese Laid-Open Patent Application No. H11-27444 can read or print documents at high speed, a user interface such as a touch panel must be used for user authentication, function setting of the device, etc.
