Abstract

A tolerant key verification method is provided. The tolerant key verification method comprises the following steps. A first key is generated instantly according to first characteristic values from a user terminal and is transmitted to a verification server to perform a comparison. When a data in the verification server matches the first key, the verification server makes no response and asks 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. When no data is available, the verification server makes no response and asks 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 second characteristic values. The verification server saves the second key and asks the network-service server to provide the network service to the user terminal.

Claims

1. 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 thefirst key, the verification server makes no response and asks 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; and

when the data is not available, the verification server makes no response and asks a message server to send a key-regeneration signal to the user is 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 asks 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.

2. The tolerant key verification method of claim 1, wherein the plurality of the first and the second characteristic values comprise an external characteristic value.

3. The tolerant key verification method of claim 2, wherein the external characteristic value is date information, time information, geographical information, country information, network-related information or weather information related to the time that the first and the second keys are generated.

4. The tolerant key verification method of claim 1, wherein the first and the second characteristic values comprise an internal characteristic value.

5. The tolerant key verification method of claim 4, wherein the internal characteristic value is a media access control (MAC) address, a storage serial number, a computer identification number or a storage directory information of the user terminal.

6. The tolerant key verification method of claim 1, wherein the first and the second characteristic values comprise a user account.

7. The tolerant key verification method of claim 1, wherein the first characteristic values comprise a first random number and the second characteristic values comprise a second random number.

8. The tolerant key verification method of claim 7, wherein the first random number and the second random number are generated by a random number generator.

9. The tolerant key verification method of claim 8, wherein the random number generator maintains the first random number at the same value after the generation of the first key and the random number generator makes the second random number different from the first random number when the random number generator generates the second key.

10. The tolerant key verification method of claim 1, wherein the network service is a network TV service, a network radio station service, an e-book database or an internet database.

11. The tolerant key verification method of claim 1, wherein when the verification server detects an abnormal condition of the user terminal, the verification server deletes the data corresponding to the user terminal that is stored in the verification server.

12. The tolerant key verification method of claim 1, wherein the verification server deletes the data corresponding to the user terminal that is stored in the verification server every fixed time interval.
