| 20080256105 | Document data creating apparatus, document data creating method and control program of the same - There is described a document data creating apparatus, a document data creating method and a program thereof, which make it possible to improve convenience of both the user and the creator of the document data by effectively utilizing the digital signature. The apparatus for creating document data that include a digital signature, includes: a character recognizing section to recognize a character based on image data inputted; a reliability determining section to determine a reliability degree of the character; a characteristic value calculating section to calculate a characteristic value of the document data; and a digital signature section to attach the characteristic value to the document data. When the reliability determining section determines that the reliability degree of the character is low, the digital signature section attaches a value, which is different from the characteristic value calculated by the characteristic value calculating section, to the document data as the digital signature. | 10-16-2008 |
| 20080266604 | IMAGE FORMING APPARATUS, PRINTING METHOD AND CONTROL PROGRAM - There is described an image forming apparatus, which makes it possible to implement a high-speed printing operation based on print data attached with a digital signature. The apparatus comprises: a storage section to store print data; a, digital signature analyzing section to analyze a digital signature; a language analyzing section to analyze the print data; an image processing section to create bitmap data; a printing section to implement a printing operation; and a control section that selectively conducts either a first controlling operation or a second controlling operation.
