Abstract

One-time password (OTP) generation apparatus and method using virtual input means are provided. Reference information generated by a reference information generation unit is compared with identification information. When the reference information is identical to the identification information, a value corresponding to indication information is generated as an OTP.

Claims

1. A one-time password (OTP) generation apparatus (10) for user authentication, comprising:

a reference information generation unit (110) configured to generate reference information; and

an OTP generation unit (130) configured to generate a value corresponding to indication information as an OTP when the reference information and identification information are identical to each other.

2. The OTP generation apparatus of claim 1, wherein the OTP generation unit (130) generates an OTP with reference to an initial value.

3. The OTP generation apparatus of claim 2, wherein the initial value is a password that is previously determined for user authentication.

4. The OTP generation apparatus of claim 2, wherein when the reference information and the identification information are different from each other, the OTP generation unit (130) sets the initial value as an OTP value.

5. The OTP generation apparatus of claim 1, wherein the reference information generation unit (110) generates the reference information by a user'"'"'s designation.

6. The OTP generation apparatus of claim 5, wherein the reference information is generated from a position, order or other terminal designated by a user.

7. The OTP generation apparatus of claim 1, wherein the reference information generation unit (110) includes a table generation unit (111) configured to generate a table of which columns is capable of being designated by a user, and information corresponding to the column of the table designated by the user is generated as the reference information.

8. The OTP generation apparatus of claim 1, wherein the reference information and the identification information are same type.

9. The OTP generation apparatus of claim 1, wherein the reference information and the identification information are information of one or more selected from the group consisting of a color, a sound, a symbol, an image, and a vibration.

10. The OTP generation apparatus of claim 1, wherein the indication information is direction indication information that indicates a specific direction.

11. The OTP generation apparatus of claim 10, wherein when the reference information and the identification information are identical to each other, an initial value is changed to a value of a direction corresponding to the direction indication information and is then generated as the OTP.

12. The OTP generation apparatus of claim 1, wherein when the OTP generation apparatus (10) is tilted or shaken the value corresponding to the indication information is a tilt or shaking value that is generated by a tilt and shaking detection unit (150).

13. The OTP generation apparatus of claim 1, further comprising a virtual input means generation unit (170) configured to generate virtual input means, wherein the generated OTP is input through the virtual input means.

14. The OTP generation apparatus of claim 13, wherein the virtual input means is a QWERTY keyboard or a virtual key pad.

15. The OTP generation apparatus of claim 13, wherein the value corresponding to the indication information is a pattern value, a repetitive input value of a specific value, or a continuous input value of a specific value, each of which is input through the virtual input means.

16. The OTP generation apparatus of claim 10, wherein the value corresponding to the indication information is a previously determined value.

17. The OTP generation apparatus of claim 1, wherein the OTP generation apparatus (10) is a server or user terminal (100).

18. The OTP generation apparatus of claim 1, wherein the reference information and the identification information are changed at every request for user authentication.

19. The OTP generation apparatus of claim 1, wherein when incorrect OTP is input three or more times, the reference information, the indication information, and the identification information are changed.

21. The OTP generation apparatus of claim 12, wherein the value corresponding to the indication information is a previously determined value.

22. The OTP generation apparatus of claim 15, wherein the value corresponding to the indication information is a previously determined value.

20. An OTP generation method for user authentication, comprising:

generating reference information by a reference information generation unit (110) (S10);

determining whether the reference information and identification information are identical to each other (S20); and

generating, by an OTP generation unit (130), a value corresponding to indication information as an OTP when the reference information and identification information are identical to each other (S30).
