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.

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： A need exists for a technology for guaranteeing the authenticity of an electronic document, and an information disclosure system, which can guarantee the authenticity of a disclosed document and delete information regarded as inappropriate for disclosure. An electronic document is divided into components, and a random number generated from a seed value is concatenated to each of the components. A hash value is calculated for each of the components with which the random numbers have been concatenated. The calculated hash values are further concatenated using a hash function to generate data to which an digital signature is applied.

摘要： Provided is a technology with which an electronic document including a plurality of elements such as texts and images may be partially encrypt and decrypt. An encryption-processing control unit receives a selection of electronic data included in an electronic document and a selection of an encryption key for encrypting the electronic data from among encryption keys stored in a storing unit. The encryption-processing control unit generates encrypted area data including partially encrypted data obtained by encrypting the selected electronic data with the selected encryption key, positional information for specifying a position of the selected electronic data in the electronic document, and decryption information including information that may specify a decryption key with which the partially encrypted data may be decrypted, and adds the encrypted area data to the electronic document.

摘要： An original signature can be verified even if a signed image data is properly altered in its portion. The digital image data is divided into a plurality of configurational elements, and each of the feature values of the elements are calculated, so that the signature is created by combining the feature values. In case the configurational elements are to be deleted, they are substituted by substitutive data, and only the feature values are stored. The verification is created by using the stored feature values as the substituted elements and by using the calculated feature values as the remaining elements, so that the signature is verified with the signature attached to the digital image data.
摘要翻译：即使签名的图像数据在其部分中被适当地改变，也可以验证原始签名。数字图像数据被分成多个配置元素，并且计算元素的每个特征值，从而通过组合特征值来创建签名。在配置要素被删除的情况下，它们被代用数据代替，只存储特征值。通过使用存储的特征值作为替代元素并通过使用计算的特征值作为剩余元素来创建验证，使得签名被附加到数字图像数据的签名来验证。
