Abstract

There are disclosed a system and method for preventing the leaking of digital content. The system for preventing the leaking of digital content may include a digital content layer generation unit for generating a digital content layer displaying digital content, a security layer generation unit for generating a security layer including security information based on information about a user terminal, and an information display unit for displaying the security layer generated by the security layer generation unit and the digital content layer generated by the digital content layer generation unit in the display device of the user terminal in an overlapping form so that the security information looks like overlapping with the digital content. Accordingly, the illegal leaking of digital content through photographing or screen capture can be prevented.

Claims

1. A system for preventing a leaking of digital information, comprising:

a digital content layer generation unit for generating a digital content layer displaying digital content;

a security layer generation unit for generating a security layer including security information based on information about a user terminal; and

an information display unit for displaying the security layer and the digital content layer in a display device of the user terminal in an overlapping form so that the security information of the security layer looks like overlapping with the digital content of the digital content layer.

2. The system as claimed in claim 1, wherein the security layer generation unit generates the security information including the information of the user terminal and applies a preset transparency to the generated security information.

3. The system as claimed in claim 2, wherein the security information includes at least any one of text indicating the information of the user terminal, encrypted information of the information of the user terminal, and digital watermark including the information of the user terminal.

4. The system as claimed in claim 2, wherein the security layer generation unit scans the digital content, contrasts the scanned digital content with security element information stored in a database, and determines whether a security element is included in the digital content based on the contrast.

5. The system as claimed in claim 2, wherein the security layer generation unit detects a position of a security element included in the digital content and designates a position of the security information on the security layer so that the security information looks like overlapping with a region corresponding to the detected position of the security element.

6. The system as claimed in claim 1, wherein a size of the security layer is any one of a size corresponding to a window in which the digital content layer is displayed and a size corresponding to a display screen.

7. The system as claimed in claim 1, further comprising a digital content selection unit for selecting the digital content in response to an external selection request signal, wherein the digital content layer generation unit extracts the selected digital content from a database and plays the extracted digital content.

8. The system as claimed in claim 1, wherein the information of the user terminal includes at least any one of terminal ID information, IP information, a Media Access Control (MAC) address, and login information of the user terminal.

9. A method of preventing a leaking of digital information, comprising:

generating a digital content layer displaying digital content;

generating a security layer including security information based on information about a user terminal; and

displaying the security layer and the digital content layer in a display device of the user terminal in an overlapping form so that the security information of the security layer looks like overlapping with the digital content of the digital content layer.

10. The method as claimed in claim 9, wherein generating the security layer comprises:

generating the security information including the information of the user terminal; and

applying a preset first transparency to the generated security information.

11. The method as claimed in claim 10, wherein the security information includes at least any one of text indicating the information of the user terminal, encrypted information of the information of the user terminal, and digital watermark including the information of the user terminal.

12. The method as claimed in claim 10, further comprising:

scanning the digital content;

contrasting the scanned digital content with security element information stored in a database; and

determining whether a security element is included in the digital content based on the contrast.

13. The method as claimed in claim 10, further comprising:

detecting a position of a security element included in the digital content; and

designating a position of the security information on the security layer so that the security information looks like overlapping with a region corresponding to the detected position of the security element.

14. The method as claimed in claim 9, further comprising selecting the digital content in response to an external selection request signal, wherein generating the digital content layer includes extracting the selected digital content from a database and playing the extracted digital content.

15. The method as claimed in claim 9, wherein the information of the user terminal includes at least any one of terminal ID information, IP information, a Media Access Control (MAC) address, and login information of the user terminal.

16. A system, comprising:

a service server and a user terminal operated in conjunction therewith over a communication network,

wherein the service server transmits digital content, requested by the user terminal, to the user terminal, and

the user terminal generates a digital content layer displaying the digital content received from the service server, generates a security layer including security information based on information about the user terminal, and displays the security layer and the digital content layer in a display device of the user terminal in an overlapping form so that the security information of the security layer looks like overlapping with the digital content of the digital content layer.

17. The system as claimed in claim 16, wherein the user terminal generates the security information including the information of the user terminal and applies a preset transparency to the generated security information.

18. The system as claimed in claim 16, wherein:

the security information includes at least any one of text indicating the information of the user terminal, encrypted information of the information of the user terminal, and digital watermark including the information of the user terminal, and

the information of the user terminal includes at least any one of terminal ID information, IP information, a Media Access Control (MAC) address, and login information of the user terminal.
