发明名称 Human interactive proof service
摘要 A human interactive proof (HIP) service is described. In response to a request from a web server, the HIP service generates a HIP challenge and an associated attestation. The web server can then embed the generated HIP challenge in a requested web page. The attestation is used to determine whether or not a user response to the HIP challenge is correct.
