s101: the method comprises the steps of obtaining face identification information of a current user, and comparing the face identification information with preset target characteristic information of a legal authentication user, wherein the target characteristic information of the legal authentication user is generated on the basis of identity information of the user extracted from a preset block chain.
In some embodiments, before obtaining the face recognition information of the current user, the method includes the following steps: identity information of uplink users and transportation equipment use requirement information.
Illustratively, the transportation device is an elevator, the user a reserves a hotel room on the hotel reservation application, submits the personal identification information of the entrant during the reservation process, and the relevant floor information, such as 'foundational building 3302 room', can be known at the same time through the reservation order, so that the personal identification information of the entrant and the elevator use demand information for 33 floors can be obtained and loaded to the blocks on the preset block chain, and then the information can be called and processed.
In some embodiments, the identity information of the user and the information of the use requirement of the transportation device may also be information of other service personnel such as courier, takeaway personnel, and the like, which may be implemented by calling data in the relevant application program, which is not limited in this embodiment of the present invention.
Blockchains are a term of art in information technology. In essence, the system is a shared database, and the data or information stored in the shared database has the characteristics of 'unforgeability', 'whole-course trace', 'traceability', 'public transparency', 'collective maintenance', and the like. Based on the characteristics, the block chain technology lays a solid 'trust' foundation, creates a reliable 'cooperation' mechanism and has wide application prospect.
The embodiment of the invention can effectively avoid the situation that lawbreakers forge legal users by introducing the block chain technology, and can trace back users of the transportation equipment, thereby facilitating the follow-up tracing. In addition, in order to facilitate normal use of the authenticated user, the embodiment of the present invention, after obtaining the face recognition information of the current user, includes the following steps:
whether a transportation equipment use record meeting preset conditions exists in a preset time period is inquired on a preset block chain based on the face identification information, if yes, a standard authentication user mode is triggered, wherein the standard authentication user mode is a user use mode without limiting the stop floor and the use time of the transportation equipment.
Preferably, the preset condition is that the number of uses of the transportation device exceeds a first preset threshold value within a preset time period and the number of persons who use the standard authenticated user mode to take a ride at each use of the transportation device exceeds a second preset threshold value.
In some embodiments, the setting of the first preset threshold and the second preset threshold may be adaptively adjusted according to specific situations, such as a higher value for a larger flow amount, a lower value for a smaller flow amount, and the opposite for the preset time period, which is not limited by the embodiment of the present invention.
S103: if the face identification information is consistent with the target characteristic information of a preset legal authentication user, triggering a temporary authentication user mode, wherein the temporary authentication user is a transportation equipment use mode for limiting the stop floor of transportation equipment and the use time of the transportation equipment; the transportation equipment stop floor and the transportation equipment use limiting time are created based on the transportation equipment use requirement information of the current user extracted from a preset block chain.
In some embodiments, the steps of creating the transportation device stop floor and the transportation device use time based on the transportation device use requirement information of the current user extracted from the preset blockchain comprise:
acquiring the condition information of the current personnel taking the transportation equipment, and confirming that the transportation equipment consumes time based on the condition information of the current personnel taking the transportation equipment;
and creating the use time limit of the transportation equipment according to the consumption time of the transportation equipment and the extracted information of the use requirement of the transportation equipment of the current user.
Specifically, the situation information of the current personnel taking the transportation equipment can be acquired through the camera device, the personnel situations of the transportation equipment taking on each floor can be acquired, the stop situations of the transportation equipment can be judged according to the personnel situations, and finally, the time consumed by the transportation equipment is calculated. And finally, creating and limiting the using time of the transportation equipment according to the consumption time of the transportation equipment and the extracted using demand information of the transportation equipment of the current user.
In some embodiments, there may be a plurality of cases where the same transportation device needs to be taken in at the same time, that is, a plurality of temporary authentication user modes need to be triggered, and the restricted transportation device usage time at this time preferably is based on the longest restricted transportation device usage time among a plurality of users, that is, the corresponding restricted transportation device usage time may be directly refreshed. Of course, the use time of the transportation device may also be limited corresponding to the last user, which is not limited in the embodiment of the present invention.
In some embodiments, limiting the time of use of the transportation device may be further optimized based on historical data, which is not limited by the embodiments of the present invention.

For example, assuming that the stop floor of the transportation device triggered by the user is 75 floors, the usage time of the transportation device is 8 seconds, and the preset threshold interval is 3 to 5, when the usage time of the transportation device is 8 seconds, the user stays at 66 floors and does not reach 75 floors, and at this time, the current user needs to be delivered to the initial floor and steps S101 to S105 need to be executed again; when the user stays at layer 71 and does not reach layer 75, the current user can be delivered to layer 75. Thus, the safety can be further improved.
