Abstract: A method and system for online proctoring of tests while preserving privacy of test-taker is disclosed. Proctoring data, which include video and audio data from at least one camera and a microphone monitoring the test-taker and the test environment, is chopped up into data fragments. Each fragment is altered to replace personally identifiable information, and the altered fragment is encrypted using a cryptographic key. The chronological order of fragments is also scrambled. Encrypted and altered data fragments are distributed to a pool of proctors who review the encrypted fragment for suspicious behavior. Suspicious fragments are further compared with original, unaltered versions of the fragments to confirm suspicious behavior, and render a verdict. The test-taker is aware of, and explicitly consents to the processing of a fragment by a proctor. A secure, custom viewer for the fragments also allows the test-taker to control the number of times a proctoring data segment can be viewed.

Abstract: A digital store comprising of a method to store digital data in live micro-organisms, and a method to selectively retrieve subsets of stored data, is disclosed. Digital data is represented as a plurality of key-value pairs. The proposed system stores copies of key-value pairs in a plurality of live micro-organisms. Upon presentation of a retrieval key, the proposed digital store retrieves the value associated with the retrieval key.

Abstract: A method of monitoring and reporting domestic abuse is disclosed. Our method and system allow a domestic abuse victim to report abuse in a safe, private, and automatic manner, and without the victim leaving any digital trail that can be traced back to the victim. Our real-time monitoring and reporting system also enables authorized agents to intervene in a timely manner and assist the victim. Our method and system detect a hand gesture made by a domestic abuse victim by analyzing video captured by an image or video capture device, and uses computer vision techniques to track the victim to a vehicle that the victim embarks or is already traveling in. Subsequently, our method positions a second image or video capture device to obtain a video that includes identifying attributes of the victim's vehicle. Computer vision techniques are used to detect the identifying attributes of the victim's vehicle like license plate, make and model of the car.
