Systems and methods for continuous authentication and monitoring

A computer-implemented method for providing continuous session authentication, the computer-implemented method comprising:

• authenticating, by session authentication circuitry at a first time, a session for a user of a client device based on an authentication image data structure and a plurality of first video frames captured before the first time;
• determining, by video monitoring circuitry, a plurality of monitor regions associated with a plurality of second video frames captured after the first time;
• assigning, by the video monitoring circuitry, a plurality of weighting values to each of the plurality of monitor regions;
• extracting, by the video monitoring circuitry, sample data from the plurality of monitor regions for each of the plurality of second video frames;
• generating, by the video monitoring circuitry, motion data based on the extracted sample data, wherein the motion data comprises motion vector data indicative of motion vectors;
• applying, by the video monitoring circuitry, the plurality of weighting values to the motion vector data to generate weighted motion vectors;
• and
• detecting, by the video monitoring circuitry at a second time, a re-authentication trigger event based on the motion data, including determining whether a magnitude of an average weighted motion vector exceeds a threshold motion vector value.

A computer program product for providing continuous session authentication, the computer program product comprising at least one non-transitory computer-readable storage medium storing computer-executable program code instructions that, when executed by a computing apparatus, cause the computing apparatus to:

• authenticate, by session authentication circuitry at a first time, a session for a user of a client device based on an authentication image data structure and a plurality of first video frames captured before the first time;
• determine, by video monitoring circuitry, a plurality of monitor regions associated with a plurality of second video frames captured after the first time;
• assign, by the video monitoring circuitry, a plurality of weighting values to each of the plurality of monitor regions;
• extract, by the video monitoring circuitry, sample data from the plurality of monitor regions for each of the plurality of second video frames;
• generate, by the video monitoring circuitry, motion data based on the extracted sample data, wherein the motion data comprises vector data indicative of motion vectors;
• apply, by the video monitoring circuitry, the plurality of weighting values to the motion vector data to generate weighted motion vectors;
• and
• detect, by the video monitoring circuitry at a second time, a re-authentication trigger event based on the motion data, including determining whether a magnitude of an average weighted motion vector exceeds a threshold motion vector value.
