The application relates to a smart park
security management method,
system, device and medium, and belongs to the technical field of smart parks, which comprises the following steps: receiving an access reservation form, identifying the
unique identifier of a visitor and a reservation event, and querying historical records in a visit event
library according to the
unique identifier to calculate initial trust points. Based on the points and the reservation event, a dynamic
authorization seed is created, and an access link containing the seed is sent to the visitor end. After entering the park, the initial dynamic access corridor and the permission accompanying unit are generated by using the dynamic
authorization seed to guide the visitor to move. When the visitor approaches the
target site, the first sub-permission is granted in the adjacent area to allow entry; after entering the
target site, the second sub-permission is granted in combination with the historical visit information of the
target site and the visitor's own
record. When it is detected that the visitor is leaving, the permission
recovery instruction is broadcasted to all network edge nodes, the visitor portrait is updated, and the local cache is emptied; the visitor experience is improved, and the security protection capability of the park is strengthened.
