Abstract: A digital MFP scans a transmission original document, and generates original document image data. A transmission original document generating unit loads information from an information storage medium, generates an information code, and composes the information code with the original document image data. The composed original document image data with the code is transmitted to a facsimile machine of another end. The facsimile machine of the other end prints out the received original document, and after necessary items are written in the printed-out original document, scans a return original document. The return image data is transmitted (returned) to the digital MFP. An image analyzing unit extracts information from the received return image data. An output control unit prints out the return image data when the information stored in the information storage medium coincides with the information extracted from the return image data.

Abstract: A communication device with a time authentication requesting function uses timestamp technology to verify a device operation. When receiving an instruction for e-document scan, the communication device transmits a hash value of scanned data of an original to a TSA, and receives a timestamp from the TSA. Then, the communication device stores the scanned data assigned with the timestamp in a prescribed folder, and stores e-document scan history. When receiving an instruction for fax communication, after carrying out fax transmission, the communication device stores fax communication history. When stored history data reaches a prescribed amount, a timer time at that point of time is added to the history data, and the history data is encoded. The communication device transmits a hash value to the TSA, and receives a timestamp from the TSA. Then, the communication device stores the history data assigned with the timestamp in a prescribed folder.

Abstract: An image processing device inputs shading correction data, which can identify the image processing device itself, to a first hash function and generates comparison data. The image processing device inputs the shading correction data to a second hash function, and generates tracing identification data. The image processing device generates a tracing pattern from the tracing identification data, and adds the tracing pattern to output image data. The image processing device verifies the comparison data with standard data, which has been generated by inputting the shading correction data in a first function and previously stored in a storage device. When the comparison data matches the standard data, the image processing device permits to print out the output image data to which the tracing pattern has been added.

Abstract: When executing e-document scan, an image scanning device scans a document and stores scanned data. After resetting a timer, the image scanning device calculates a hash value of the scanned data, and transmits the calculated hash value to a TSA to request the TSA to issue a timestamp. When receiving a timestamp from the TSA, the image scanning device stores the scanned data and the timestamp in an e-document folder. When failing to receive a timestamp within a prescribed period of time after requesting the timestamp, the image scanning device adds a comment to the scanned data indicating that the timestamp failed to be received, and prints out the scanned data with the comment.

Abstract: An image forming device scans an original document and generates a bi-level image signal. The image forming device obtains a first counted value by counting black pixels included in the bi-level image signal. The image forming device obtains a first generation copy by forming an image on a printing medium according to the bi-level image signal of the original document. The image forming device scans the first generation copy and generates a second bi-level image signal. The image forming device obtains a second counted value by counting the black pixels included in the second bi-level image signal. The image forming device compares whether or not the second counted value is within a target range of the first counted value, and controls the density of an image to be formed according to the comparison result.

Abstract: An image scanning device with a time authentication requesting function enables documents, not subject to be converted into e-documents, to be easily converted into e-documents at a later date, and reduces costs required for assigning a timestamp. When a user instructs an account book e-document temporary scan, an original is scanned and stored. An account book temporary file name is assigned to the scanned original, and stored in an account book temporary folder. When the user instructs an estimate e-document temporary scan or a purchase order e-document temporary scan, scanned data of the original is assigned with a file name and stored in a temporary folder of each document type. Documents not subject to be converted into e-documents are stored under the same format as the e-document, and a timestamp is assigned collectively to necessary documents at a later date. Accordingly, costs required for the timestamp can be reduced.
