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.

Security management system and security management method

A method and device for event displaying, a computer-readable storage medium, and an electronic device. The method comprises: acquiring parameter information of multiple users in a preset area (S); determining, on the basis of parameter information, the probabilities of events to be displayed being triggered (S); and determining, on the basis of the probabilities, a duration for displaying said events in the preset area (S). The method overcomes the problem of data resource wastage in the prior art in which a greater number of invalid events are displayed when displaying events without taking into consideration parameter information of users.

Method and device for event displaying, storage medium, and electronic device

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.

Pedestrian tracking method, computing device, pedestrian tracking system and storage medium

The present application relates to the technical field of computers, and provides a user request response method, a user request response apparatus, a computer-readable storage medium, and an electronic device. The user request response method comprises: upon the reception of a user request sent from a first-type terminal, sending reminder messages to a plurality of second-type terminals according to the user request; receiving message receipts for the reminder messages within a preset time period; selecting a target message receipt from among the message receipts according to a preset rule; and using the second-type terminal corresponding to the target message receipt as a target second-type terminal and determining to respond to the user request according to the target second-type terminal.

User request response method and apparatus, computer-readable storage medium, and device

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.

Target tracking method, device, system and non-transitory computer readable storage medium

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