摘要： A computer extracts the header information from an electronic mail, including an originality guarantee. The computer generates a header characterization for the header information subject to originality guarantee, and extracts message body information from the electronic mail and generates a body characterization for the message body information as well. The generated characterization set applies the header characterization and the body characterization, combined. The verification information is added to the generated characterization set for applying a signature, and characterization set is linked to electronic mail.

摘要： When input data (f0) is read into a digital signature generating apparatus, a hash value (h0) is calculated. The hash value (h0) is stored to a storage area (M1), which has the highest priority rank among 5 storage areas. Subsequently, when input data (f1) is read in, a hash value (h1) is calculated. Since the storage area (M1) is already occupied by the hash value (h0), the hash value (h0) is read out from storage area (M1), emptying the storage area (M1). The read hash value (h0) and the hash value (h1) are concatenated, forming a concatenated hash value (h0|h1) and a hash value (h0,1) is calculated. The hash value (h0,1) is stored to a storage area (M2), which has the highest priority rank after the storage area (M1). When input data (f2) is read in, a hash value (h2) is calculated and stored to the storage area (M1).
摘要翻译：当将数据（f0）读入数字签名生成装置时，计算散列值（h0）。散列值（h0）被存储到在5个存储区域中具有最高优先级的存储区域（M1）。随后，当读入输入数据（f1）时，计算散列值（h1）。由于存储区域（M1）已经被哈希值（h0）占据，所以从存储区域（M1）读出散列值（h0），从而清空存储区域（M1）。读取散列值（h0）和散列值（h1）被级联，形成连接的散列值（h0 | h1）和哈希值（h0,1）。哈希值（h0,1）被存储到在存储区域（M1）之后具有最高优先级的存储区域（M2）。当读入输入数据（f2）时，计算散列值（h2）并将其存储到存储区域（M1）。

摘要： An electronic image data verification program disclosed herein is capable of detecting presence or absence of a change, specifying a changed portion (the position of a change) if present, and making the presence or absence and the changed portion provable to third parties, by generating partial signature information separately from electronic image information to be registered, by dividing and maintaining the partial signature information, and by clearly separating functions/roles of the electronic image information (original information) and the partial signature information (verification information). The present invention comprises: a partial signature information generation section 40 that uses partial information of electronic image information, to generate partial signature information for specifying presence or absence of a change to the electronic image information and a changed portion if a change has been made; a registration section 70 that registers the electronic image information and the partial signature information generated from the electronic image information; a storage section 80; and a partial signature verification section 50 that uses the electronic image information and the partial signature information registered by the registration section, to verify presence or absence of the change to the electronic image information, or a changed portion if a change has been made to the electronic image information.

摘要： Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data.At the registration time of new document information, the digital document management program manages a digital signature created in association with document information. At the correction time of the document information, the program acquires partial identification information related to a corrected part of the document information before correction, creates a digital signature to be appended to the corrected document information, and manages the digital signature and partial identification information related to the corrected part of the document information in association with the corrected document information. At the verification time, the program uses partial identification information, the partial identification information corresponding to a corrected part of the document information before correction, and digital signature to perform verification.
