Abstract(in English) | Digital signature does not allow any alteration of the document. However, "appropriate" alteration should be allowed for some signed document because of other security requirements etc. Disclosure of official information is a typical example of this. Sensitive information such as private information should be sanitized from the original digitally signed document when it is disclosed. "Digital document sanitizing problem" is the problem that signed document cannot be verified if some part of the signed document is concealed. In this paper, we propose new digital signature techniques which can solve digital document sanitizing problem. |
