Objective To discuss allocation method of personnel access in the fingerprint entrance guard system and solution to the problem of the authority personnel's being tailed or or coerced in the specific area.Methods Using database to implement personnel rights allocation;using two security doors to form a closed space to implement the anti-tail function:setting up the linkage of the two doors,making switch state of the first door become precondition of opening and closing of the second door.Results When people came into a particular area,their fingerprints were scanned;the scanned fingerprint was compared with the fingerprint information saved in the database,thus successfully shutting out of those without permissions;when authorized personnel was followed or coerced,the anti-tail function module sent signals to alarm management personnel to take corresponding measures,thus avoiding accidental damage.Conclusion Permission setting is to used define personnel's access scope,which,to a great extent,alleviates the burden of the management;design of anti-tail and anti-coerce module effectively prevents some criminals,reduces economic loss and ensures the staff's personal safety at the same time.
