System and method for privacy-aware analysis of video streams

A system for performing privacy-aware movement tracking, the system comprising:

• at least one processor;
• at least one memory coupled to the processor and storing instructions executable by the processor and that such execution causes the processor to perform operations comprising:
• receiving a first series images of containing movement of a first unidentified person;
• generating a first movement dataset for the first unidentified person based on tracking movement of the first unidentified person within the first series of images;
• determining a first characterizing feature set for the first unidentified person;
• associating the first characterizing feature set with the first movement dataset, thereby forming a first track entry;
• receiving a second series of images containing movement of a second unidentified person;
• generating a second movement dataset for the second unidentified person based on tracking movement of the second unidentified person within the second series of images;
• determining a second characterizing feature set for the second unidentified person;
• associating the second characterizing feature set with the second movement dataset, thereby forming a second track entry;
• and
• determining a match between the first track entry and the second track entry;
• wherein:
• for at least one given image of the first series of images, a first body region corresponding to the first unidentified person is anonymized by removing identifying features within the first body region, thereby generating a first anonymized body region;
• for at least one given image of the second series of images, a second body region corresponding to the second unidentified person is anonymized by removing identifying features within the second body region, thereby generating a second anonymized body region;
• the first characterizing feature set for the first unidentified person is determined based on processing of the first anonymized body region and is associated with the first movement dataset to form the first track entry;
• and
• the second characterizing feature set for the second unidentified person is determined based on processing of the second anonymized body region;
• and is associated with the second movement dataset to form the second track entry.
