System for Calculating Trust of Client Session(s)

Abstract:

Described herein is a system for calculating trust of a client session. A proof of work value is received from a session of a client computer. The proof of work value is calculated by the session of the client computer based, at least in part, upon a work function and input(s) received from service(s) connected to the session. A probability that the session is trustworthy is calculated based, at least in part, upon the proof of work value. Feedback is provided to the session of the client computer based, at least in part, upon the calculated probability. The feedback can increase complexity or frequency of calculation. The feedback can include an update to the work function.
