s4, according to the use monitoring instruction, a monitoring flow is called, and based on the monitoring flow, image monitoring is carried out on the position of a requesting user and a card reading position through image acquisition equipment, so that a use monitoring image set is obtained;
s5, determining monitoring features according to the monitoring flow, and respectively carrying out feature traversal analysis on the using monitoring image set based on the monitoring features to obtain feature matching results;
and S6, when the feature matching result meets the requirement of using the monitoring parameters, generating tag execution information, wherein the tag execution information is used for opening tag control operation authority for a requesting user.
5. The method for multi-target identification based on radio frequency identification technology according to claim 4, wherein the performing the usage security analysis on the tags, determining the usage risk influence degree of each tag, and setting the security management requirement of each tag based on the usage risk influence degree, comprises the following steps:
b1, when the tag is stored, transmitting an RFID signal bound with the tag;
b2, receiving corresponding RFID signals based on the transmitted RFID signals;
b3, formulating a corresponding RFID monitoring protocol based on the received RFID signals;
when the labels are taken, obtaining label type information and label use range information;
b5, constructing a tag use record database based on the tag type information and the tag use range information;
b6, extracting tag risk events from the tag use record database, and analyzing the robbery frequency, the influence range and the multidimensional influence degree of the influence result according to the tag risk event record information to obtain the multidimensional risk influence degree;
b7, calculating the using risk influence according to the stealing frequency, the influence range, the preset weight value of the influence result and the multidimensional risk influence;
and B8, setting a security management level according to the influence of the use risk, and setting security management requirements of the tag based on the security management level.
6. The method of claim 5, wherein verifying the tag use request based on the request verification parameters comprises the steps of:
c1, obtaining user information of a tag use request;
performing authority verification on the user information, and performing level matching according to the user authority and the request verification parameters after passing the authority verification to determine authority level matching parameters;
and C3, generating a verification instruction to verify the tag use request based on the permission level matching parameter.
