Description

[0001] Printed document management system and method [

The present invention relates to an output document management system and a method thereof. And more particularly, to an output document management system and method capable of preventing an output document from leaking out to the outside and managing the life cycle of an output document.

In recent years, information leaks have become a serious problem in organizations such as corporations. Especially, confidential documents such as drawings, which are used only within the company, are increasingly being stolen, leaked, or lost. Accordingly, various methods for securing confidential documents have been developed. One of them is the use of DRM (Digital Right Management) technology to distribute various confidential documents to a specific user by setting an expiration date or the like as an encrypted file so that when the password is unknown or the expiration date has passed, . In addition, a method of automatically converting a document into a PDF file to prevent document tampering and illegal viewing has been suggested. That is, conventional security solutions mainly focus on encrypting documents and limiting the handling of confidential documents encrypted according to user rights.

Such a conventional document security method has a problem that the security of the copying or leakage of the printed document is not substantially secured. In other words, when a user with viewing or printing authority copies a confidential document to an unauthorized user in an arbitrary judgment or outputs it to the outside of the printer, or outputs the confidential document to an unauthorized person easily There is a problem that the security of the secret document can not be secured.

Most organizations use computers to perform their tasks, and documents are often shared and circulated in electronic form. However, documents are often printed in the form of printouts. However, only the contents of the document were recorded in a document printed by a conventional method, so that it was not possible to know who printed it, when, and where. Therefore, even if the document is leaked, it is not clear whether the output document is stored or leaked, resulting in poor security of the output.

As described above, according to the technical idea of the present invention, when the target document is output, the output document identification information that can identify the information about the target document and / Can be printed together. That is, for example, if a digital pattern of a predetermined rule is printed together in a document found outside the organization, it can be confirmed that the found document is a document leaked from the organization. In addition, since the outgoing document itself has digital information for identifying the outgoing document printed thereon, the printed digital information can be compared with the DB storing the document output details, so that a user who easily outputs the outgoing document can be obtained. Therefore, it is possible to emphasize security to the users who output the document.

Meanwhile, according to an embodiment of the present invention, the digital pattern printed on the output document may be composed of a small unit pattern, and the small unit pattern may be a small dot pattern capable of representing several bytes to several tens bytes. Therefore, even if the leaked document is finely shredded, a perfect dot pattern can be left, and if any dot pattern is perfectly found, information on leaked document, document output, etc. can be obtained.

Referring back to FIG. 2, when the destruction management module 130 detects a digital pattern printed on an output document to which the document destruction apparatus 50 is inserted and transmits a destruction signal indicating that the output document has been destroyed, Can be stored in the database (20).

On the other hand, some of the output documents may be documents that should be discarded within a predetermined period. In this case, for example, as shown in <Table 1>, a destruction period may be set for the destruction-scheduled document. The warning module 140 determines whether or not a specific output document is not destroyed by the document destroying device 50 within the scheduled destruction time, that is, within a predetermined period of destruction from the document destroying device 50, It is possible to output a warning signal. The warning module 140 may output a warning signal by an account of a predetermined administrator terminal or an administrator.
