摘要： A communication terminal device using timestamp technology officially certifies transmission completion time. When a start key is pressed, and e-document scan is instructed, scanned image data is stored as an e-document along with a timestamp received from a Time Stamping Authority (TSA). When facsimile transmission is carried out, and log e-document storing transmission is selected, a hash value of data composed of communication log data and image data transmitted by facsimile is transmitted to the TSA, and log file data and a timestamp are stored as an e-document.

摘要： When a preset time elapses from a previous certificate revocation list acquired date and time, it is determined whether or not a signature confirmation event is stored in a signature confirmation execution list. When the signature confirmation event is stored, contents of the signature confirmation execution list are classified for each certificate authority, and one certificate authority is selected. For the selected certificate authority, the preset time after the date and time when the latest signature confirmation was executed is decided as the certificate revocation list acquiring date and time. Then, the certificate revocation list acquiring date and time is decided for all necessary certificate authorities. When the decided certificate revocation list acquiring date and time is reached, access is made automatically to the certificate authority, and a certificate revocation list is acquired.

摘要： When a preset activation time is reached, or when a digital MFP is activated manually, a determination is carried out as to whether or not a certificate revocation list is necessary to be acquired. Then, the digital MFP acquires and stores a certificate revocation list when necessary. The digital MFP determines whether or not a certificate of a signature confirmation execution list is included in the acquired certificate revocation list to determine whether or not an e-document of which a signature has been confirmed is invalid. When the e-document is invalid, the digital MFP creates text data indicating that a corresponding TSA and the e-document are invalid, and prints out the created text data. After deleting contents of the signature confirmation execution list, when the activated time is determined to be a preset activation time, the digital MFP is shut down.
