Abstract

CAPTCHA (Completely Automated Public Test to tell Computers and Humans Apart) data generation methods for use in a server and related management systems are provided. First, the server determines a first data set according to at least one first data corresponding to an operation to be performed, wherein the first data represents a sensitive data corresponding to the operation. Then, the server generates a group of CAPTCHA data corresponding to the first data set according to the first data.

Claims

1. A data generation method for CAPTCHA (Completely Automated Public Test to tell Computers and Humans Apart) data generation for a server, comprising:

determining a first data set according to at least one first data corresponding to an operation, wherein the first data represents sensitive data corresponding to the operation; and

generating a group of CAPTCHA data corresponding to the first data set according to the first data.

2. The data generation method as claimed in claim 1, further comprising:

hiding corresponding encrypted data into each CAPTCHA data, wherein the encrypted data includes information corresponding to the operation.

3. The data generation method as claimed in claim 2, wherein the group of CAPTCHA data with the encrypted data is transmitted to a client, which is used by the client with the encrypted data to perform the operation with the server.

4. The data generation method as claimed in claim 2, further comprising:

generating summary information according to the information corresponding to the operation.

5. The data generation method as claimed in claim 4, wherein the operation comprises a plurality of operational steps, and the information corresponding to the operation included in the encrypted data comprises second data, wherein the second data represents a corresponding operational step for the encrypted data.

6. The data generation method as claimed in claim 5, wherein the information corresponding to the operation included in the encrypted data comprises third data, wherein the third data represents identification information of a user of the client.

7. The data generation method as claimed in claim 2, wherein the encrypted data is a watermark.

8. The data generation method as claimed in claim 1, wherein the method of generating the group of CAPTCHA data corresponding to the first data set according to the first data further comprises:

dividing the first data set into a plurality of data segments according to a property of the first data; and

generating a corresponding CAPTCHA data for each data segment.

9. The data generation method as claimed in claim 8, wherein the first data comprises numeric data, and each data segment is one or a plurality of numbers.

10. The data generation method as claimed in claim 8, wherein the first data comprises character data, and each data segment is one or a plurality of characters.

11. The data generation method as claimed in claim 1, wherein each CAPTCHA data comprises image data, video data, or audio data.

12. A data generation system for CAPTCHA (Completely Automated Public Test to tell Computers and Humans Apart) data generation, comprising:

a server determining a first data set according to at least one first data corresponding to an operation, and generating a group of CAPTCHA data corresponding to the first data set according to the first data, wherein the first data represents sensitive data corresponding to the operation.

13. The data generation system as claimed in claim 12, wherein the server further comprises a generation module, and the generation module is configured to determine the first data set according to the first data, and generate the group of CAPTCHA data corresponding to the first data set.

14. The data generation system as claimed in claim 13, wherein the server further comprises an encryption module, and the encryption module is configured to hide corresponding encrypted data into each CAPTCHA data, wherein the encrypted data includes information corresponding to the operation.

15. The data generation system as claimed in claim 14, wherein the server transmits the group of CAPTCHA data with the encrypted data to a client, which is used by the client with the encrypted data to perform the operation with the server.

16. The data generation system as claimed in claim 14, wherein the generation module generates summary information according to the information corresponding to the operation.

17. The data generation system as claimed in claim 16, wherein the operation comprises a plurality of operational steps, and the information corresponding to the operation included in the encrypted data comprises second data, wherein the second data represents a corresponding operational step for the encrypted data.

18. The data generation system as claimed in claim 17, wherein the information corresponding to the operation included in the encrypted data comprises a third data, wherein the third data represents identification information of a user of the client.

19. The data generation system as claimed in claim 14, wherein the encrypted data is a watermark.

20. The data generation system as claimed in claim 12, wherein the generation module divides the first data set into a plurality of data segments according to a property of the first data, and generates a corresponding CAPTCHA data for each data segment.

21. The data generation system as claimed in claim 20, wherein the first data comprises numeric data, and each data segment is a number.

22. The data generation system as claimed in claim 20, wherein the first data comprises character data, and each data segment is one or a plurality of characters.

23. The data generation system as claimed in claim 12, wherein each CAPTCHA data comprises image data, video data, or audio data.

24. A non-transitory machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a data generation method for CAPTCHA (Completely Automated Public Test to tell Computers and Humans Apart) data, comprising:

a first program code for determining a first data set according to at least one first data corresponding to an operation, wherein the first data represents sensitive data corresponding to the operation;

a second program code for generating a group of CAPTCHA data corresponding to the first data set according to the first data; and

a third program code for hiding corresponding encrypted data into each CAPTCHA data in the group of CAPTCHA data, wherein the encrypted data includes information corresponding to the operation.
