摘要： PROBLEM TO BE SOLVED: To provide an electronic document authenticity assurance technique and an information disclosure system both of which can compatibly realize the assurance of the authenticity of disclosure documents and the deletion of information inappropriate for disclosure. SOLUTION: An electronic document is divided into constituent elements and a signature is affixed to an arbitrary subset of a set including all the constituent elements. Otherwise, a signature is affixed to data obtained by binding each of the constituent elements to information specifying the relationship between a respective one of the constituent elements and the structure of the electronic document. Otherwise, the hash values of the respective constituent elements are calculated and a signature is affixed to data obtained by binding the calculated hash values together. Otherwise, random numbers generated for the respective constituent elements are bound together, then the hash values of the respective random-numbered constituent elements are calculated, and then an electronic signature is affixed to data obtained by binding the calculated hash values together.

摘要： PROBLEM TO BE SOLVED: To solve the problem that it takes time and labor when developing a program and a system coping with a plurality of file types and sanitizable signature methods since the sanitizable signature method capable of verifying a part of a signed electronic document even after deleted (sanitized) depends on both of the file type of the object electronic document and the sanitizable signature method. SOLUTION: A series of procedures relating to a sanitizable signature are separated into procedures depending on a signature object document and the procedures depending on the sanitizable signature method. Thus, even when newly increasing the kinds of the electronic document to be the signature object for instance, just the procedure depending on the signature object document is added and the procedures depending on the sanitizable signature method are not needed to be changed. Similarly, even when newly increasing the sanitizable signature method, just the procedure depending on the sanitizable signature method is added and the procedures depending on the signature object document are not needed to be changed.

摘要： PROBLEM TO BE SOLVED: To make the chain of a chain structure of signature log data hardly broken when a digital signature is generated, utilizing the chain structure, and restrain the number of required signature log data for verifying the chain structure.
SOLUTION: A log management unit requests a signature generator to generate a digital signature utilizing signature log data stocked in a log stocker so that a plurality of log stockers mutually share information of the signature log data and registers the generated digital signature as signature log data in other log stockers. For verifying the digital signature using the signature log data, a signature verifier sends the signature log data to the log management unit and requests requirements about the signature log data, and the log management unit retrieves suitable signature log data from information of stocked signature log data and sends the data to the signature verifier.

摘要： PROBLEM TO BE SOLVED: To assure authenticity by allowing appropriate changes in vector image data and multi-layer image data, and to enable ensuring the authenticity. SOLUTION: A signer device 102 divides vector image data or multilayer image data into a plurality of constituents, calculates feature values of each constituent, generates an electronic signature from one obtained by coupling the feature values, and stores the electronic signature in an original image storing device 103 with signature. When a constituent is to be deleted, a sanitizer device 104 stores only the feature values in a disclosure image storing device 105. A verifier device 106 verifies the electronic signature by using the stored feature values for the deleted constituents, and by using newly calculated feature values for the undeleted constituents.
