Method, device and system for preventing cross-site request forgery

Abstract

The embodiment of the application discloses a method, device and system for preventing cross-site request forgery. The method comprises the following steps: a client sends local terminal equipment information to a server when accessing the server at the first time; the server generates environment fingerprint information according to the terminal equipment information; the server stores the environment fingerprint information as the preset verification information; the server sends the environment fingerprint information to the client; when the data interaction is performed between the client and the server, the client sends an access request message containing the environment fingerprint information to the server; the server receives the access request message and judges whether the access request message comprises the environment fingerprint information matched with the stored preset verification information; and the server responds to the access request message according to a judgment result. Through the adoption of the method disclosed by the embodiment of the application, the cross-site request forgery can be effectively prevented, and the security of the terminal equipment is improved.

Benefits of technology

This technology prevents unauthorized use or communication attempts made over an internet connection while ensuring security for user devices accessing it through secure connections like HTTPS (Hypertext Transfer Protocol Secure) protocol. It also checks if any harmful signals were detected during interaction before sending them out again afterward without compromising their privacy rights.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to protect against attacks such as CrossSite Request Falsification (XSF). XFS uses cookies or similar tokens to identify different websites with specific content but no valid identities are provided during authentication process. To address these issues, there has been proposed various techniques like generating unique identifier values based upon predetermined rules instead of just sending them over all possible URLs.
