A system to generate perform document optimizations is described. The system includes at least one physical memory device and one or more processors coupled with the at least one physical memory device, the one or more processors to receive a request to securely communicate with a client computing device, including a fingerprint identifier (ID) associated with the client computing device, transmit a fingerprint challenge to the client computing device, wherein the fingerprint challenge comprises a manipulation to be performed on a segment of a fingerprint file associated with the fingerprint ID, receive a challenge response from the client computing device and verify the challenge response.
