Password verifying device and method

A password verifying device, comprising a control unit, a storage unit, several input circuits, and a display screen;

• the storage unit stores a password sequence;
• the control unit is intended to perform a program realized by said method;
• the display screen is used to provide interactive regions for the program implemented by the method;
• each input circuit is electrically connected to the control unit and corresponds to a respective interactive region;
• switching-on of each input circuit will transform this switching-on status into instructions of selecting a corresponding interactive region.

A password verifying device, comprising a control unit, a voice input unit, a storage unit, and a display screen. The storage unit stores a preset password sequence and said predefined label;

• the control unit is intended to perform a program realized by said method;
• the display screen is used to provide interactive regions for the program implemented by the method;
• the voice input unit is electrically coupled with the control unit. The voice input unit receives voice data input;
• when it is found by the control unit that the input voice data is identical to one of the predefined labels, an instruction of selecting an interactive region associated with said predefined label is output.

A password verifying device, comprising a control unit, an image recognition unit, a storage unit, and a display screen;

• the storage unit stores a preset password sequence and said predefined label;
• the control unit is intended to perform a program realized by said method;
• the display screen is used to provide interactive regions for the program implemented by the method;
• the image recognition unit is electrically coupled with the control unit;
• the image recognition unit captures face image of the user, extracts eyes feature information from the image, and recognizes open/close status of the eyes;
• when it is found by the control unit that the eyes feature information is identical to one of the predefined labels representing status data, an instruction of selecting an interactive region associated with said predefined label is output.
