[0025] First, the first embodiment will be explained.
[0026] FIG. 1 is a diagram schematically showing a network structure. As shown in FIG. 1 , an image forming apparatus 1 is connected to a communication network 2 . A personal computer (PC) and a file server 4 serving as data storage devices are also connected to this communication network 2 . For example, the image forming apparatus 1 is a copier having a network scanning function. Electronic data representing an image read from a paper document by the network scanning function of this image forming apparatus 1 is stored in the PC 3 via the communication network 2 . After image data is subjected to processing for applying a digital signature by the PC 3 (details of the processing will be described later), the image file subjected to this processing is stored in the file server 4 .
[0027] FIG. 2 is a block diagram showing the main structure of the PC 3 in the first embodiment. As shown in FIG. 2 , the PC 3 has a data...

[0034] A second embodiment will be described below. The same components as those of the first embodiment are denoted by the same reference numerals and symbols, and detailed descriptions of these components are omitted.
[0035] In the process of collectively signing a plurality of electronic data, it is not known whether the content of the electronic data has been confirmed by the user to be correct. Therefore, the PC 3 judges whether or not the content of the electronic data has been correctly confirmed by the user, and records information indicating the judgment result. The PC 3 that applies a digital signature only to electronic data whose contents have been confirmed to be correct among a plurality of electronic data will be described below.
[0036] FIG. 5 is a block diagram showing the main structure of the PC 3 in the second embodiment. As shown in FIG. 5 , the PC 3 has a data acquisition unit 31 , a data display unit 32 , a content confirmation judgment unit 33 , a ...

[0056] A third embodiment will be described below. The same components as those in the first embodiment are denoted by the same reference numerals and symbols, and detailed descriptions of these components are omitted.
[0057] In the third embodiment, when applying a digital signature to electronic data whose content has been confirmed by the user, the image quality of the electronic data is checked, and after asking the user whether the digital signature can be applied to the electronic data, the digital signature is applied to the electronic data. for electronic data with low image quality.
[0058] Fig. 12 is a block diagram showing the main structure of the PC 3 in the third embodiment. As shown in FIG. 12 , the PC 3 has a data acquisition unit 41 , a data display unit 42 , an image quality inspection unit 43 , a signature unit 44 , and a data transfer unit 45 . Since data acquisition unit 41, data display unit 42, and data transfer unit 45 are the same as data acquisit...
