Abstract: The present disclosure provides a pedestrian tracking method including: acquiring at least one piece of first video data and at least one piece of second video data; performing facial recognition on at least some first images of the first image frames to obtain tracking data of a first pedestrian including position information thereof at N moments; performing human body detection on at least some second images of the second image frames to obtain tracking data of a second pedestrian including a movement track thereof; determining tracking data of a target pedestrian when deviation between the position information of the first pedestrian at the N moments and the position information of the movement track of the second pedestrian at the same moments is within a preset range. The present disclosure also relates to a pedestrian tracking apparatus, a computing device, a pedestrian tracking system, and a computer-readable storage medium.

Abstract: The present disclosure relates to a target tracking method, device, system, and a non-transitory computer-readable storage medium. The method includes: determining an area where a current target is located by performing target detection on a current frame image; extracting a current position information of the area where the current target is located; predicting a position information of an area where each historical target is located at a corresponding moment of the current frame image based on historical position information of an area where each historical target is located in one or more historical frame images; determining a historical target that is the same target as the current target based on a position difference between the current position information and the predicted position information, and tracking the current target.

Abstract: A security management system includes a first server. The first server is configured to: obtain access information of a terminal device; generate, if the access information of the terminal device meets an access condition, a first key based on a registration time of the terminal device, identification information of the terminal device, and fingerprint information of the terminal device; encrypt the first key using a second key, the first key being different from the second key; and send the encrypted first key to the terminal device, so that the terminal device decrypts the encrypted first key using the second key.
