Systems and methods for passive continuous session authentication

A computer-implemented method for generating behavioral attribute data structures, the computer-implemented method comprising:

• generating, by video monitoring circuitry, a video data structure comprising a video stream captured over a duration of time, wherein the video stream comprises a plurality of video frames;
• extracting, by biometric attribute generation circuitry, a set of biometric attributes from the video stream;
• generating, by the biometric attribute generation circuitry, a biometric attribute data structure comprising the set of biometric attributes extracted from the video data structure;
• generating, by sensor circuitry, a sensor data structure comprising (i) a set of sensor data captured over the duration of time, wherein the set of sensor data comprises a plurality of subsets of native sensor data, and (ii) a plurality of pointers, wherein each of the plurality of pointers is associated with a respective one of the plurality of subsets of native sensor data;
• and
• generating, by behavioral attribute generation circuitry, a behavioral attribute data structure from the sensor data structure and the biometric attribute data structure, wherein the behavioral attribute data structure comprises a set of behavioral attributes of a user derived from the set of sensor data.

A computer program product for generating behavioral attribute data structures, 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:

• generate a video data structure comprising a video stream captured over a duration of time, wherein the video stream comprises a plurality of video frames;
• extract a set of biometric attributes from the video stream;
• generate a biometric attribute data structure comprising the set of biometric attributes extracted from the video data structure;
• generate a sensor data structure comprising (i) a set of sensor data captured over the duration of time, wherein the set of sensor data comprises a plurality of subsets of native sensor data, and (ii) a plurality of pointers, wherein each of the plurality of pointers is associated with a respective one of the plurality of subsets of native sensor data;
• and
• generate a behavioral attribute data structure from the sensor data structure and the biometric attribute data structure, wherein the behavioral attribute data structure comprises a set of behavioral attributes of a user derived from the set of sensor data.
