When a predetermined security pattern is included in output data for a printout in which a print is requested by the user terminal, the print security device 100 may acquire a printing policy corresponding to a detected security pattern from a print security policy which is provided from the security management device 200, and perform a print security operation on the output data according to the acquired printing policy.
Here, the security pattern may be a pattern including at least one among letters, numbers, and symbols, and be desirably personal information, but is not limited thereto. Further, the security pattern may be previously set by a manager, or be provided from the security management device 200. For example, the security pattern may be a character composition pattern with respect to the personal information such as a social security number, a license number, an e-mail address, etc. shown in Table 1
Further, the print security operation may be constituted by a combination of the following five security operations. A first security operation may be an operation of allowing/blocking a print of the output data. A second security operation may be an operation of changing contents of the detected security pattern. For example, the second security operation may be the operation of changing the contents of the security pattern into a predetermined character string (‘*’, etc.), or of changing the contents of the security pattern into a predetermined font or a character type. A third security operation may be an operation of requesting approval on a print of the output data to a predetermined management terminal. A fourth security operation may be an operation of providing information on the print of the output data to the management terminal. For example, the fourth security operation may be the operation of notifying a predetermined manager of information such as the contents of the output data, a print request time, etc. through an e-mail/SMS, etc. A fifth operation may be an operation of storing image/text log information on a predetermined page among total pages of the output data.
Further, the print security policy may include the print security operation and the security pattern mapped each other. For example, as shown the following Table 2, the print security operation and the security pattern is mapped with respect to each printing policy.
The security management device 200 may provide the print security policy which is previously set by a manager to the print security device 100.
The user terminals 300-1 to 300-n may request a print on the output data for the printout according to a user's operation. The user terminals 300-1 to 300-n may be a television, a computer, a tablet personal computer (PC), a personal digital assistant (PDA), a portable multimedia player (PMP), a mobile phone, a smart phone, a navigation device, etc.
The printer 400 may be an output device for printing information which is processed by the computer in a form capable of being seen by human's eyes. The printer 400 may be a thermal transfer printer, an ink-jet printer, a laser printer, etc.
The communication network 500 may be a data communication network such as a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), the Internet, etc., and also include a broadcast network, a telephone network, etc. Further, the communication network 500 may be a wired or wireless network, and include every communication method.
