Claim:
A tolerant key verification method, comprising the steps of: generating a first key instantly according to a plurality of first characteristic values from a user terminal; transmitting the first key to a verification server; comparing the first key with a data stored in the verification server; when the data in the verification server matches the first key, the verification server makes no response to the user terminal and requests a network-service server to provide a network service to the user terminal; when the data doesn't match the first key, the verification server makes no response to the user terminal; and when the data is not available, the verification server makes no response to the user terminal and requests a message server to send a key-regeneration signal to the user terminal such that the user terminal generates a second key instantly according to a plurality of second characteristic values and transmits the second key to the verification server so that the verification server saves the second key and requests the network-service server to provide the network service to the user terminal, wherein the message server and the verification server are whether the same server or two different servers.
