Using the ability to read out as human dialogue proof

摘要

The human interaction proof portal uses biometric input to determine whether the user is a standard user or a malicious actor. The human interaction proof portal receives a request for access to the online data service from the user device and sends a proof challenge to the user device for presentation to the user. The human interaction certification portal receives from the user device a certification response having a biometric metadata description based on a biometric input from the user.
