Abstract
Official abstract text for this publication.
An electronic document encrypting system 200 , for accomplishing an object of providing a system capable of distributing an electronic document containing important information with a browsing restriction being set and information with none of the browsing restriction being set without removing the important information, includes: an encryption area extracting unit 19 extracting an encryption target area from an electronic document; a digital image generating unit generating a digital image on the basis of the area extracted by the encryption area extracting unit in the electronic document; an encrypting unit 11 encrypting the digital image generated by the digital image generating unit 15 on the basis of an encryption key; and an encrypted electronic document generating unit 12 generating an encrypted electronic document in which when the electronic document is output, in place of the extracted information, an encrypted image encrypted by the encrypting unit 11 is output to an area to which the information extracted by the encryption area extracting unit 19 is to be output.
First claim
