Abstract:
A method for generating one or more human interactive proofs (HIPs) is described herein. A HIP request may be received. One of a plurality of HIP engines may be selected using a randomization algorithm. Each HIP engine may have a distinct algorithm for generating the one or more HIPs. The one or more HIPs may be generated using the one of the plurality of HIP engines.
