  • Patent number: 8893233
    Abstract: A referer verification apparatus and method for controlling web traffic having malicious code are provided. In the referer verification method, whether a referer is present in a Hypertext Transfer Protocol (HTTP) packet is determined. If it is determined that the referer is present in the HTTP packet, Uniform Resource Locators (URLs) are extracted from a referer web page corresponding to the referer. The referer is verified based on a URL corresponding to a referer verification request received from a server and the extracted URLs. A Completely Automated Public Test to tell Computers and Humans Apart (CAPTCHA) verification procedure conducted by a user is performed based on results of the verification of the referer.

  • Publication number: 20140020067
    Abstract: An apparatus and method for controlling traffic based on a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) are provided. The traffic control apparatus includes a traffic monitoring unit, a CAPTCHA verification unit, a list management unit, and a traffic control unit. The traffic monitoring unit monitors a packet between an internal network and an external network. The CAPTCHA verification unit, if packet information is not present in an access control list, sends a CAPTCHA request message to a client computer, receives a CAPTCHA response message, and verifies the CAPTCHA response message. The list management unit, if the packet information is present in the access control list, detects an access control policy corresponding to the packet information in the access control list. The traffic control unit controls traffic based the verification of the CAPTCHA response message and the control policy.

  • Publication number: 20140013389
    Abstract: A communication blocking control method includes receiving a communication blocking request from a terminal in an idle state in which it is difficult to find out whether information is leaked or not; registering a state of the terminal in a communication blocked list according to the communication blocking request; and blocking external communication of the terminal through a network.

  • Patent number: 8375428
    Abstract: The present invention relates to a password input algorithm, more particularly to a password input system and method using alphanumeric matrices. An aspect of the invention can provide a password input system and method using alphanumeric matrices that can defend against keylogging attacks and shoulder surfing attacks by including a movable second alphanumeric matrix and a fixed first alphanumeric matrix and enabling a user to input a password by moving the password letters of the second alphanumeric matrix to the user-defined value of the first alphanumeric matrix. Another aspect of the invention can provide a password input system and method using alphanumeric matrices that can defend against shoulder surfing attacks by enabling a user to input a password by dividing the password by every two digits and moving the cross-points for the two digits, respectively, to the user-defined value of the first alphanumeric matrix.

  • Publication number: 20110004769
    Abstract: The present invention relates to a password input algorithm, more particularly to a password input system and method using an alphanumeric matrix. An aspect of the invention can provide a password input system and method that can defend against keylogging attacks and shoulder surfing attacks, by having the final password inputted by way of certain alphanumeric matrix letters which are separated by a particular distance from the letters forming the password in the alphanumeric matrix. Also, an aspect of the invention can provide a password input system and method that can further increase the probability of defending against keylogging attacks and shoulder surfing attacks, by having the final password inputted by way of certain alphanumeric matrix letters which are separated by a particular distance from the letters forming the password in the alphanumeric matrix, but with the alphanumeric matrix rotated every time a letter is inputted.
