摘要： The present invention provides an electronic document authenticity assuring method in which a series of procedures concerning redactable signature are divided into procedures dependent on a document to be signed and procedures dependent on a redactable signature method. Further, the present invention provides program codes that realize the divided procedures and a system comprising apparatuses for implementing those program codes. According to the present invention, even when type of electronic document to be signed is changed or added to, it is sufficient to add a procedure dependent on a document to be signed, without changing procedures dependent on redactable signature methods. Similarly, even when a redactable signature method is to be changed or added, it is sufficient to add a procedure dependent on the redactable signature method without changing procedures dependent on document to be signed.

摘要： Disclosure of information is controlled selectively depending on users such that a plurality of users having different roles bearing no inclusive relation with one another can access the same area. Content is divided into a plurality of areas. For each of the areas obtained by division, secret keys (encryption/decryption keys in symmetric-key cryptography) are generated. The generated keys are encrypted using public keys in public-key cryptography, which are set in advance for the users depending on their respective roles. In the case where the content is to be disclosed to a plurality of users having different roles, the encryption of secret keys is performed separately for each user. These encrypted contents and encrypted secret keys are used to generate encrypted text.
