Abstract (in Japanese) (See Japanese page) 
(in English) Digital signatures do not allow any alteration of a document. However, for some signed documents ”appropriate” alteration should be allowed when other security concerns arise. Disclosure of official information is a typical example of this. Such sensitive information as private information, when it is disclosed, should be sanitized from the original digitally signed document. “The digital document sanitizing problem” occurs when the signed document cannot be verified since part of the signed document is concealed. The already proposed sanitizing scheme[4] can solve the digital document sanitizing problem. In this paper we assume the acceptance of a suggestion to change the sanitizing phrase. We proposed on SUMI coating method which can change the coating parts to protect against insider attacks.
