SYSTEM AND METHOD FOR IMPLEMENTING ROBOT PROOF WEB SITE |
摘要 |
The invention prevents robots from browsing a Web site beyond a welcome page. When an initial request from an undefined originator is received, the Web site responds to it with a welcome page including a challenge. Then, on receiving a further request from the undefined originator, the Web site can check whether the challenge is fulfilled or not. If fulfilled, the undefined originator is assumed to be a human being and authorized to go on. If the challenge is not fulfilled, the undefined originator is assumed to be a robot, in which case site access is further denied. The invention prevents Web site contents from being investigated by robots while not requiring users to have to log on. |
