Abstract

The invention provides an image reading apparatus and an image forming apparatus. The image reading apparatus includes: an original reading section reading an image from an original and generating image data on the read image; a key generation section generating a key for encrypting on the basis of the image data generated by the original reading section; an encrypting section encrypting the image data generated by the original reading section with the key generated by the key generation section; and a transmission section transmitting the image data encrypted by the encrypting section to a terminal connected with the outside. Hence, the apparatus of the invention can suppress increase of cost and increase clutter degree of random number as encrypted key.

Description

technical field [0001] The present invention relates to an image reading device that encrypts and transmits image data read from a document, and an image forming device that forms an image on paper based on the image data obtained by the image reading device. Background technique [0002] In recent years, leakage of confidential information has become a major problem in companies, governments, and autonomous organizations, and technologies for preventing leakage of confidential documents have been desired. In addition, companies, governments, and local governments are increasingly using information technology (IT) to share information and reduce management costs through digitization of paper. [0003] On the other hand, in image forming apparatuses such as copiers, with the development of digitization, the technology of acquiring original images as electronic data and sending the image data read from the originals to other terminal devices via the network has been known to t...
