Abstract

A document security system is disclosed. In the document security system, when a user is permitted to use a device and to use a document, a process for the document requested by a user is executed bythe device. Further, after executing the process, a follow-up obligation is executed corresponding to the type of the document obtained from image data of the document.

Description

technical field [0001] The present invention generally relates to a document security system in which a document job requested by a user is executed when the device-based usage right allows the user to use a document processing device and the document-based usage right allows the user to perform the job, and corresponding to the Document execution obligations. Background technique [0002] Recently, the importance of keeping documents secure has been largely recognized, and the need to keep company secrets has increased. In addition to electronic documents handled on personal computers, also in printed documents from electronic documents and in documents transmitted or received by facsimile, the necessity to keep documents secure has increased. [0003] In particular, in image processing apparatuses having multiple functions for processing paper documents and electronic documents, the necessity to keep documents secure has increased. [0004] In Patent Documents 1 and 2 an...
