Abstract

An electronic device includes an access control module, a plurality of input areas, and a comparing module. The access control module has a predetermined password. The input areas are configured to be tapped to input characters in the electronic device. The number of the input areas is determined by the number of unique characters of the predetermined password. The comparing module is configured to compare a sequence of the characters entered with the predetermined password.

Claims

1. An electronic device comprising:

an access control module having a predetermined password comprising a plurality of characters, and at least two of the plurality of characters are identical in the predetermined password;

a plurality of input areas configured to be tapped to input characters in the electronic device, the plurality of input areas shown by a display module before inputting a password, the plurality of input areas displaying the plurality of characters before being tapped, and the at least two identical characters displayed in one of plurality of input areas, and the number of the input areas being less than the number of the plurality of characters of the predetermined password; and

a comparing module configured to compare the password consist of the inputted characters with the predetermined password.

2. The electronic device of claim 1, wherein the number of the input areas is equal to the number of different characters in the predetermined password.

3. The electronic device of claim 2, wherein a plurality of sensors is corresponding to the plurality of input areas and configured to enter the corresponding characters.

4. The electronic device of claim 2, wherein the comparing module is capable of comparing the sequence of tapping each of the input areas with the order of the characters presented in the predetermined password.

5. The electronic device of claim 1, wherein the display module is a touch screen.

6. The electronic device of claim 1, wherein the number of tapping times of all the input areas is more than the number of the plurality of input areas.

7. The electronic device of claim 1, wherein an order of the plurality characters displayed in the plurality of input areas is random.

8. An electronic device comprising:

an access control module having a predetermined password consist of a plurality of characters, and at least two of the plurality of characters are identical in the predetermined password;

a plurality of password input areas shown by a display module, each of the plurality of password input areas displays each different character in the plurality of characters before inputting a password, and the at least two identical characters displayed in one of plurality of input areas; and

each of the plurality of password input areas is adapted to be tapped to enter the displayed character in the electronic device; and

the number of the plurality of password input areas is determined by the number of the different characters; and

a comparing module capable of comparing the sequence and the number of tapping each of the password input areas with the order of the characters in the predetermined password.

9. The electronic device of claim 8, wherein the number of the password input areas is equal to the number of the plurality of different characters of the plurality of characters.

10. The electronic device of claim 9, wherein the number of tapping times of all the input areas is more than the number of the plurality of input areas.

11. The electronic device of claim 8, wherein a plurality of sensors is corresponding to the plurality of password input areas and configured to enter the corresponding characters when the corresponding password input area is tapped.

12. The electronic device of claim 8, wherein an order of each of the plurality of input areas is random.

13. The electronic device of claim 8, wherein the display module is a touch screen.

14. An electronic device comprising:

an access control module having a predetermined password comprising at least two identical characters and at least one another characters different from the two identical characters;

at least two input areas configured to be tapped to input characters in the electronic device, the plurality of input areas shown by a display module when prompting for a password;

the two identical characters displayed in one of the at least two input areas and the another character displayed in the other one of the at least two input areas when prompting for the password;

a plurality of sensors corresponding to the input areas and configured to enter the corresponding characters when the corresponding input area is tapped; and

a comparing module configured to compare the inputted characters input from the sensors with the predetermined password.

15. The electronic device of claim 14, wherein the comparing module is capable of comparing the sequence and a tapping times of tapping each of the input areas with the order of the characters presented in the predetermined password.

16. The electronic device of claim 14, wherein the number of the input areas is equal to the number of different characters of the predetermined password.

17. The electronic device of claim 14, wherein the number of the input areas is less than the number of all characters of the predetermined password.

18. The electronic device of claim 14, wherein an order of the characters displayed in the plurality of input areas is random.
