Abstract

The present invention discloses an information processing device and the switching method for the password input mode thereof. The information processing device includes a usage scene monitoring unit configured to monitor the usage scene or the usage environment of the information processing device and a password input switching unit, configured to judge the usage scene or the usage environment of the information processing device 1 based on the output of the usage scene monitoring unit and to determine whether the password input mode should be switched based on the judgment result.

Claims

1. An information processing device, comprising:

a usage scene monitoring unit, configured to monitor the usage scene or the usage environment of the information processing device; and

a password input switching unit, configured to judge the usage scene or the usage environment of the information processing device based on the output of the usage scene monitoring unit and determine whether the password input mode should be switched based on the judgment result.

2. The information processing device according to claim 1, wherein:

if the password input switching unit determines that the information processing device is in a first usage scene or use environment, the password input switching unit sets the password input mode to a first password input mode; and

if the password input switching unit determines that the information processing device is in a second usage scene or usage environment, the password input switching unit sets the password input mode to a second password input mode.

3. The information processing device according to claim 2, wherein:

the first usage scene of the information processing device is a notebook usage scene of the information processing device;

the second usage scene of the information processing device is a pad usage scene of the information processing device;

in the first password input mode, the password is acquired by pressing the keyboard or clicking the mouse; and

in the second password input mode, the password is acquired by the user'"'"'s touch track on the touch screen.

4. The information processing device according to claim 2, wherein

the usage scene monitoring unit is an ambient light sensing unit, configured to monitor the ambient light intensity around the information processing device;

the first usage environment is an environment where the ambient light intensity around the information processing device is higher than a preset threshold value; and

the second usage environment is an environment where the ambient light intensity around the information processing device is lower than the preset threshold value.

5. The information processing device according to claim 4, further comprising:

a face recognition unit, configured to recognize the user'"'"'s face image taken by the information processing device, in order to enable/disable the user to use the information processing device; and

a voice recognition unit, configured to recognize the user'"'"'s voice recorded by the information processing device, in order to enable/disable the user to use the information processing device,

wherein in the first password input mode, the user is enabled/disabled to use the information processing device based on the user'"'"'s face recognition; and

in the second password input mode, the user is enabled/disabled to use the information processing device based on the user'"'"'s voice recognition.

6. A switching method for password input modes of the information processing device, comprising:

monitoring the usage scene or usage environment of the information processing device;

judging the usage scene or usage environment of the information processing device based on the monitoring result; and

determining whether the password input mode should be switched based on the judging result.

7. The switching method according to claim 6, wherein:

if it is determined that the information processing device is in a first usage scene or use environment, the password input mode is set to a first password input mode; and

if it is determined that the information processing device is in a second usage scene or usage environment, the password input mode is set to a second password input mode.

8. The switching method according to claim 7, wherein:

the first usage scene is a notebook usage scene of the information processing device;

the second usage scene is a pad usage scene of the information processing device;

in the first password input mode, the password is acquired by pressing the keyboard or clicking the mouse; and

in the second password input mode, the password is acquired by the user'"'"'s touch track on the touch screen.

9. The switching method according to claim 7, wherein the monitoring the usage scene or usage environment of the information processing device further comprises:

monitoring the ambient light intensity around the information processing device,

wherein, the first usage environment is an environment where the ambient light intensity around the information processing device is higher than a preset threshold value; and

the second usage environment is an environment where the ambient light intensity around the information processing device is lower than the preset threshold value.

10. The switching method according to claim 9, wherein

in the first password input mode, the user is enabled/disabled to use the information processing device based on the user'"'"'s face recognition;

and

in the second password input mode, the user is enabled/disabled to use the information processing device based on the user'"'"'s voice recognition.
