Claim 18:
19. A computer program product including a non-transitory computer readable medium with instructions, said instructions enabling a computer to perform online proctoring while preserving privacy of test-taker, said instructions comprising:
a. instructions for a camera and microphone to capture and record proctoring data in chronological order, where proctoring data includes video and audio data captured by cameras and microphones to monitor the test-taker and the test environment;
b. instructions for a privacy-preserving mediator unit to chop up said proctoring data into one or more proctoring data fragments, alter said proctoring data fragments to remove personally identifiable information, scramble the chronological order of the said altered proctoring data fragments;
c. instructions for a privacy-aware proctor unit to distribute said scrambled, altered proctored data fragments to a pool of sub-proctors;
d. instructions for a privacy-aware sub-proctor unit that inspects a data fragment and determines suspicious behavior by test-taker;
e. instructions for a privacy-aware arbiter unit that reviews altered proctoring data fragments for suspicious behavior, compares with original, unaltered fragments retrieved from said privacy-preserving mediator unit, and renders a verdict on integrity of test-taker.
