SYSTEM FOR DETECTING REAL TIME FORGERY AND ALTERATION OF WEB CONTENT AND METHOD THEREFOR

摘要

The present invention relates to a system and a method for detecting the forgery and alteration of web contents on a real-time basis. The system includes: a web server (10) which receives a forgery/alteration verification information with an electronic signature from a verification information generation server (20) after transmitting web configuration elements to the verification information generation server (20) and transmits the web configuration elements and the received forgery/alteration verification information with a forgery/alteration verification module to a client (30); a verification information generation server (20) which generates verification information including a message digest and HMAC for the respective web configuration elements after receiving the web configuration elements from the web server (10) and transmits the forgery/alteration verification information generated by adding the electronic signature to the verification information to the web server (10); and a client (30) which executes the forgery/alteration verification module after receiving the forgery/alteration verification module and forgery/alteration verification information from the web server (10), generates another message digest with the web configuration elements received from the web server (10), and determines whether the web configuration elements are forged or altered by comparing the generated message digest and the message digest for the web configuration elements and matching the received forgery/alteration verification information and verifying the information thereof.
