Method and apparatus for authentication based on fingerprint recognition

1. A fingerprint recognition based authentication method, comprising:

outputting a screen displaying a plurality of symbols;

obtaining, via a sequence of touch inputs to the screen,

a sequence of input symbols selected by a user from among the plurality of symbols displayed on the screen, the sequence of input symbols being symbols from among the displayed plurality of symbols that are touched by the sequence of touch inputs, and

a sequence of input fingerprints corresponding to the sequence of touch inputs; and

performing user authentication based on,

a comparison between the sequence of input symbols and a reference sequence of symbols, and

a comparison between to the sequence of input fingerprints and a reference sequence of fingerprints.

2. The method of claim 1 , further comprising:

determining whether registered fingerprints matching the input fingerprints are present among registered fingerprints stored in a storage device.

3. The method of claim 1 , wherein the performing of the user authentication comprises:

determining the user authentication to be unsuccessful in response to the sequence of input symbols differing from the reference sequence of symbols or the sequence of input fingerprints differing from the reference sequence of fingerprints.

4. A fingerprint recognition based authentication method, comprising:

outputting a screen displaying a plurality of symbols;

obtaining, via a touch input to the screen,

an input symbol selected by a user from among the plurality of symbols displayed on the screen, the input symbol being a symbol from among the displayed plurality of symbols that is touched by the touch input, and

an input fingerprint corresponding to the touch input; and

performing user authentication based on,

whether the input fingerprint matches a registered fingerprint of a user, and

whether a mapped symbol matches the input symbol,

the mapped symbol being a symbol that corresponds to the input fingerprint in accordance with preregistered fingerprint-symbol mapping information.

5. The method of claim 4 , wherein the performing of the user authentication comprises:

determining whether an input fingerprint detected from a touch input matches a registered fingerprint each time a touch input is made.

6. The method of claim 4 , wherein the obtaining of the input fingerprint comprises:

obtaining the input fingerprint from the touch input at a preset point in a time section in which the touch input is made.

7. The method of claim 4 , wherein the obtaining of the input fingerprint comprises:

obtaining the input fingerprint from the touch input when a number of touch inputs applied to the screen reaches a threshold value.

8. The method of claim 4 , wherein the performing of the user authentication comprises:

performing the user authentication based on whether a pattern corresponding to a sequence of touch inputs to the screen is identical to a preregistered pattern.

9. The method of claim 4 , wherein the obtaining of the input symbol and the input fingerprint comprises:

obtaining a sequence of input symbols and a sequence of input fingerprints based on a sequence of touch inputs to the screen.

10. The method of claim 4 , wherein the performing of the user authentication comprises:

determining whether a number of input fingerprints that match a registered fingerprint among input fingerprints detected from a touch input sequence to the screen, the number being based on a preset security level.

11. The method of claim 4 , wherein the obtaining of the input fingerprint comprises:

obtaining a plurality of input fingerprints from a multi-touch input.

12. The method of claim 4 , wherein the performing of the user authentication comprises:

performing the user authentication based on whether an input order of input fingerprints obtained from a touch input sequence to the screen is identical to a preregistered fingerprint input order.

13. A non-transitory computer readable medium storing a computer program which, when executed, configures a processor to perform the following:

outputting a screen displaying a plurality of symbols;

obtaining, via a sequence of touch inputs to the screen,

a sequence of input symbols selected by a user from among the plurality of symbols displayed on the screen, the sequence of input symbols being symbols from among the displayed plurality of symbols that are touched by the sequence of touch inputs, and

a sequence of input fingerprints corresponding to the sequence of touch inputs; and

perform user authentication based on,

a comparison between the sequence of input symbols and a reference sequence of symbols, and

a comparison between to the sequence of input fingerprints and a reference sequence of fingerprints.

14. A fingerprint recognition based authentication apparatus, comprising:

memory storing computer-executable instructions; and

a hardware processor configured to execute the computer-executable instructions such that the hardware processors is configured to,

output a screen displaying a plurality of symbols,

obtain, via a sequence of touch inputs to the screen,

a sequence of input symbols selected by a user from among the plurality of symbols displayed on the screen, the sequence of Input symbols being symbols from among the displayed plurality of symbols that are touched by the sequence of touch inputs, and

a sequence of input fingerprints corresponding to the sequence of touch inputs, and

perform user authentication based on,

a comparison between the sequence of input symbols and a reference sequence of symbols, and

a comparison between to the sequence of input fingerprints and a reference sequence of fingerprints.
