  • Patent number: 8966606
    Abstract: Disclosed are a DLP security system and an operating method thereof. An operating method of a data loss prevention (DLP) apparatus, comprising: converting, into packets, Ethernet signals received from a fail over device that are transmitted and received between an external network and internal network; analyzing the packets to classify the packets into first packets required to be precisely judged and second packets not required to be precisely judged; distributing and allocating a judgment job about the first packet to at least one in-line instance according to a predetermined reference; and allocating the judgment job distributed to the in-line instance in which a fail occurs to the in-line instance which is normally operated when it is verified whether there is an in-line instance which is normally operated in the case where the fail occurs in the at least one in-line instance.

  • Publication number: 20140108755
    Abstract: Disclosed are a mobile DLP system and method. The mobile DLP system includes a general storage that allows an access in a normal mode and a security mode, an encrypted virtual storage that disallows an access in the normal mode and allows an access in the security mode, a management program that designates the general storage as a write/read area in the normal mode and designates the general storage and the virtual storage as the write/read area in the security mode, a fuse that intercepts a file input/output of an application program including the management program to again set a file input/output path as the virtual storage according to a command of the management program in the security mode, and a VFS engine that performs a bridge function between the application program of an application layer and the fuse of a kernel layer.

  • Publication number: 20140101751
    Abstract: Provided is a network-based data loss prevention (DLP) system. The network-based DLP system includes a FPGA engine including a pattern matcher and a MCP engine including a session list filter. The a pattern matcher hash-processes a payload of an input packet in units of a certain size, compares a pre-stored pattern and the hash-processed packet, checks a matching rule ID and an upload channel ID corresponding to the pre-stored pattern when there is a match therebetween, adds tagging information to a header of the input packet, and outputs the packet. The session list filter receives the packet with the tagging information added thereto, and performs pre-registered processing on the pre-registered session, or passes the received packet. The processor uploads, forwards, or drops the received packet in correspondence with the matching rule ID.

  • Patent number: 7843405
    Abstract: A plasma display apparatus and method of driving the same is disclosed. The plasma display apparatus includes a calculation unit for calculating an average picture level of an input picture, a sub-field mapping unit for mapping data of the input picture to a first sub-field group and a second sub-field group, and a controller for controlling a time range between the data mapped to the first sub-field group and the data mapped to the second sub-field group according to the average picture level. If the average picture level is calculated at a first level, a generating time point of the data mapped to the second sub-field group is controlled to be at a first starting time point. If the average picture level is calculated at a second level higher than the first level, the generating time point of the data mapped to the second sub-field group is controlled to be at a second starting time point later than the first starting time point.
