Patent number: 10237207Abstract: An apparatus and method for storing data traffic on a flow basis. The apparatus for storing data traffic on a flow basis includes a packet storage unit, a flow generation unit, and a metadata generation unit. The packet storage unit receives packets corresponding to data traffic, and temporarily stores the packets using queues. The flow generation unit generates flows by grouping the packets by means of a hash function using information about each of the packets as input, and to store the flows. The metadata generation unit generates metadata and index data corresponding to each of the flows, and stores the metadata and the index data.Type: GrantFiled: September 23, 2015Date of Patent: March 19, 2019Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jihyung Lee, Sungryoul Lee, Junghee Lee, Yung Yi, KyoungSoo Park

Patent number: 9342366Abstract: An intrusion detection apparatus and method using a load balancer responsive to traffic conditions between a central processing unit (CPU) and a graphics processing unit (GPU) are provided. The intrusion detection apparatus includes a packet acquisition unit, a character string check task allocation unit, a CPU character string check unit, and a GPU character string check unit. The packet acquisition unit receives packets, and stores the packets in a single task queue. The character string check task allocation unit determines the number of packets in the packet acquisition unit, and allocates character string check tasks to the CPU or the GPU. The CPU character string check unit compares the character strings of the packets with a character string defined in at least one detection rule inside the CPU. The GPU character string check unit compares the character strings of the packets with the character string inside the GPU.Type: GrantFiled: October 15, 2013Date of Patent: May 17, 2016Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Junghee Lee, Sungryoul Lee, Deokjin Kim, Young Han Choi, Byungchul Bae, HyungGeun Oh, Kiwook Sohn, KyoungSoo Park, Yung Yi, Jihyung Lee, Sangwoo Moon

Patent number: 7895653Abstract: Embodiments of the present invention provide a method, system and computer program product for bot detection for network distributable markup. In accordance with an embodiment of the present invention, a page request for distributed markup can be processed to incorporate embedded fragment within the requested page. For instance, the fragment can include a script enabled to detect human activity within the requested page such as a mouse movement. Alternatively, the fragment can include an extraneous markup artifact. The requested page subsequently can be returned to the requestor and the embedded fragment can be monitored to detect the presence of a bot depending upon the activation of the artifact. For example, where human activity can be detected within the page or where the extraneous markup artifact becomes activated despite the extraneous nature of the artifact, a human requestor can be concluded.Type: GrantFiled: May 31, 2007Date of Patent: February 22, 2011Assignee: International Business Machines CorporationInventors: Seraphin B.
