A hidden information-based security system includes a security agent. The security agent includes: a hidden information module configured to search for custom.xml by analyzing the source code of electronic document data executed by an operating system-based word processor unit, and to identify authority information; a content execution module configured to control the content execution of the electronic document data by the word processor unit according to the control of a security module; and the security module configured to generate hidden information, in which a security agent-dedicated fmtID is designated, by hiding custom.xml, in which authority information for security of electronic document data is configured, at a specific location in source code of the corresponding electronic document data by using a steganographic technique, and to compare the authority information with reference information and restrict an allowable range of content.

Hidden information-based security system for electronic documents

A system and method for tracking the path of an electronic document are provided. The system includes: a log information update unit including: a unique ID generation module configured to, when first electronic document data being loaded in an operating system-based word processor unit is newly created as second electronic document data due to a change in the storage location or name thereof, newly generate a unique ID for the second electronic document data and modify the unique ID of the first electronic document data to a parent ID; and a log information update module configured to generate or update a storage path as log information, and to include the log information in the second electronic document data; and a path tracking unit configured to search for the log information and to identify an execution history from the found log information.

Method and system for tracking path of electronic document

A network-based document protection system for the protection of business secret includes: a template module configured to search for the template information of a template stored in a template database (DB) or the document information of a document stored in a document DB, and to execute the corresponding template or document via a dedicated application; an authentication module configured to generate the document information by including the identification code of an operator in the corresponding template information or to identify a corresponding operator by recognizing an identification code from the document information of the executed document, according to the execution procedure of the template module; and a security module configured to store the document, generated or updated via the dedicated application, in the document DB, and to perform security processing on the document.

Network-based document protection system for protection of business secret

A security system for software to be input to a closed internal network includes: a kiosk including a registration module configured to read the stored software of a connected portable storage medium, a vaccine module configured to detect malicious code in the software, and an authentication module configured to set inspection authentication for the portable storage medium whose software has been inspected for malicious code; and a client including a check module configured to check the portable storage medium for inspection authentication and authorize the execution of the stored software.
