Abstract

A system and method for generating a disguised password are provided. The method presets a real password via an input device, selects one or more characters from the real password as a verification code. The method further generates an encryption code corresponding to the verification code according to an encryption algorithm, generates a character string based on the encryption code, and displays a verification box on a display screen to receive an input key from the input device. In addition, the method determines whether the input key matches the encryption code of the character string, and generates a disguised password by replacing the verification code with the encryption code in the real password if the input key matches the encryption code of the character string.

Claims

1. A system for generating a disguised password, the system comprising:

a password disguising unit stored in a storage device; and

at least one processor operable to execute the password disguising unit, the password disguising unit comprising;

a key value encrypting module operable to preset a real password received from an input device, select one or more characters from the real password as a verification code, and generate an encryption code corresponding to the verification code according to an encryption algorithm;

a verification code identifying module operable to generate a character string based on the encryption code when the real password is input from the input device, display a verification box on a display screen to receive an input key from the input device, and determine whether the input key matches the encryption code of the character string; and

a disguised password generating module operable to generate a disguised password by replacing the verification code with the encryption code in the real password if the input key matches the encryption code of the character string.

2. The system according to claim 1, further comprising an input key monitoring module operable to monitor and obtain the real password from the input device.

3. The system according to claim 1, wherein the key value encrypting module is further operable to store the encryption code into the storage device.

4. The system according to claim 1, wherein the input key monitoring module determines whether any other real password is inputted from the input device.

5. The system according to claim 1, wherein the input device is a keyboard, a keypad, or a touch screen.

6. A method for generating a disguised password, the method comprising:

presetting a real password received from an input device;

selecting one or more characters from the real password as a verification code;

setting an encryption code corresponding to the verification code according to an encryption algorithm;

generating a character string based on the encryption code when the real password is input from the input device;

displaying a verification box on a display screen to receive an input key from the input device;

determining whether the input key matches the encryption code of the character string; and

generating a disguised password by replacing the verification code with the encryption code in the real password if the input key matches the encryption code of the character string.

7. The method according to claim 6, further comprising:

storing the encryption code into a storage device; and

displaying the disguised password on the display screen to an authorized user.

8. The method according to claim 6, further comprising:

determining whether any other real password is inputted from the input device; and

monitoring and obtaining the real password if any other real password is inputted from the input device.

9. The method according to claim 6, wherein the input device is a keyboard, a keypad, or a touch screen.

10. A storage medium having stored thereon instructions that, when executed by a processor of a computing device, cause the computing device to perform a method for generating a disguised password, the method comprising:

presetting a real password received from an input device;

selecting one or more characters from the real password as a verification code;

setting an encryption code corresponding to the verification code according to an encryption algorithm;

generating a character string based on the encryption code;

displaying a verification box on a display screen to receive an input key from the input device;

determining whether the input key matches the encryption code of the character string; and

generating a disguised password by replacing the verification code with the encryption code in the real password if the input key matches the encryption code of the character string.

11. The storage medium according to claim 10, wherein the method further comprises:

storing the encryption code into a storage device; and

displaying the disguised password on the display screen to an authorized user.

12. The storage medium according to claim 10, wherein the method further comprises:

determining whether any other real password is inputted from the input device; and

monitoring and obtaining the real password if any other real password is inputted from the input device.

13. The storage medium according to claim 10, wherein the input device is a keyboard, a keypad, or a touch screen.
