Computerized CAPTCHA Systems Using A Direct Connection With User Computing Device

摘要

Computerized CAPTCHA systems using a direct connection with user computing devices are provided. An example computerized CAPTCHA system is configured to perform operations. The operations include receiving a request from a user computing device to engage in a verification process. The request is received independent of a resource provider from which the user computing device has requested a resource. The operations include providing a challenge to the user computing device at least in part in response to the request for engagement in the verification process and receiving a response to the challenge from the user computing device. The operations include determining whether the user computing device should be verified based at least in part on the response and providing a verification token to the user computing device when it is determined that the user computing device should be verified.
