Recently, the sanitizable signature attracts much attention since it allows to modify (sanitize) the document for hiding partial information without keeping the integrity of the disclosed subdocuments. Sanitizable signatures are quite useful in governmental or military offices, where there is a dilemma between disclosure laws for public documents and privacy or diplomatic secrets. Since a verifier can detect whether the document was sanitized or not, especially which subdocuments was sanitized, the scheme does not establish the perfect hiding. In order to solve the problem, the deletable signature was introduced in 2006. However, because these schemes are not compatible to each other, we have to select the scheme to meet the requirement. In this paper, we propose the sanitizable and deletable signature as a combination of the sanitizable signature and the deletable signature. We also establish two concrete sanitizable and deletable signatures based on the deletable signature by Miyazaki, Hanaoka and Imai.
