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. Our method and system ensure the privacy of the proctoring data by explicitly authorizing every entity that processes a proctoring data fragment, and limiting number of views of the fragment, while allowing independent evaluation of proctoring data for different forms of cheating.

The use of a magnetic particle based “PUF” (Physically Unclonable Function) disk, when read by magnetic sensor(s), as a positional encoder is described. It is often necessary to include a linear or rotary encoder within a device for tracking motor movements, or to enable a closed-loop control algorithm on the motor system. These randomly dispersed magnetic particle disks can be used as a positional encoder, where the speed of movement and the direction of movement may be monitored.

A method of calculating a carbon credit includes performing, for each segment of a route, a segmental carbon-emission calculation procedure to calculate a segmental carbon emission amount, calculating a one-trip carbon emission amount for this round of taking the route by adding up the segmental carbon emission amounts of all segments, calculating a one-trip emission comparison amount based on the one-trip carbon emission amount and a carbon emission average amount, adding the one-trip emission comparison amount to a cumulative comparison carbon credit, outputting the cumulative comparison carbon credit thus updated, and updating the carbon emission average amount.

Various aspects described herein relate to presenting drug dispensing information. Data related to a plurality of dispensing events initiated by one or more employees, of an electronic drug dispensing system can be received. A set of dispensing events of the plurality of dispensing events can be determined as constituting possible misappropriation of drugs by the one or more employees. An alert related to the set of dispensing events can be provided based on determining that the set of dispensing events constitute possible misappropriation of drugs.

Apparatus and methods of artificial intelligent based provision of digital content where and when the digital content is needed based upon where a user is located and a purpose for accessing the content as well as credentials of a user seeking to access the digital content. Persistent digital content is linked to location coordinates. More specifically, the present invention links a physical onsite location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with location specific digital content. In addition, access to digital content may be limited to users in defined access areas.

A collectible is provided. The collectible includes a viewer operable to display content. The viewer has a body which at least partially encapsulates a processor and a display. The body forms a recess which is operable to at least partially receive a remote. The remote is operable to control the viewer. When the remote is at least partially received within the viewer, the remote and the viewer together form a design which corresponds to a theme. The content displayed by the viewer also corresponds to the theme. The display has a size that is smaller than 2 inches.
