Image processing system, program and method

A non-transitory readable-by-computer recording medium recorded with an image processing program making a computer to execute:

• accepting an input of rendering information for depicting a content of electronic data;
• generating a digital image configured to have an aggregation of pixels based on the rendering information of which the input is accepted by said rendering information input accepting;
• acquiring definition information containing area designating information for specifying an encrypting target partial area in the digital image generated by said digital image generating and key information used on the occasion of encrypting the target partial area;
• encrypting involves generating an encrypted image into which an image of the target partial area is encrypted by converting the image of the target partial area specified based on the area designating information based on the key information;
• outputting the encrypted image corresponding to the content of the electronic data, which is generated by said encrypting;
• making said computer to execute retaining a plurality of predefined pieces of definition information associated with pieces of identifying information for identifying the definition information;
• and
• acquiring the identifying information by image recognizing from the digital image generated by said digital image generating,
• wherein said definition information acquiring acquires the definition information containing the area designating information and the key information used for generating the encrypted image by said encrypting from the plurality of predefined pieces of definition information retained by said definition information retaining based on the identifying information acquired by said identifying information acquiring.
