Embodiment Construction

[0012] As shown in FIG. 1 , it is a hardware architecture diagram of an input device realizing its internal data protection in an embodiment. In this embodiment, for ease of description, the input device is a mouse, but it is not limited thereto, and it can be other types of input devices, such as track balls, stylus pens, joysticks and other input devices. The mouse 11 includes a connection interface 110, a storage unit 111, a pressure sensor 112, a microcontroller 113, a locking unit 114, a plurality of input keys 115, a coordinate output circuit 116, a button / wheel control circuit 117 and A display screen 118 .

[0013] The connection interface 110 is used to connect the mouse 11 to a computer system 10, and the connection interface 110 can be a USB interface or a PS / 2 interface. The input keys 115 can be number keys, letter keys, or a combination of number keys and letter keys, and are used to generate input signals. The input key 115 also includes a password setting key...

Abstract

An input device and its code control method, and it has the data storage function. It includes the coordinate output circuit, a button and roller control circuit, many input button, a storage element and a microcontroller which contains a code compare module and an unlock module. The input button can be numerical button, alpha button or alphanumeric button. The code compare module accepts the input signal from the input button, when the signal is consistent with the code, it can produce an unlock information to the unlock module which can release the lock of the storage element according to the unlock information and restore the validity of the visit operation. When the input signal includes a password setting information, the password compare module will change the password to the input information of the setting password. So based on the password control function, it can decrease the risk of password unlock and prevent others visiting the storage element randomly to protect the data on the input device.

Description

【Technical field】 [0001] The invention relates to a password control device and a password control method thereof, in particular to an input device with a password control function and a password control method thereof. 【Background technique】 [0002] As society enters informationization, computers have become an indispensable product in people's lives. The input device, as one of the main tools for providing the operation interface between the human and the computer, makes the input of the computer simpler and more convenient. There are many kinds of computer input devices, such as mouse, trackball, stylus, joystick and other input devices. Among them, the mouse is a frequently used input device, and its function design is changing with each passing day, from wired mouse to wireless mouse, from mechanical From optics to infrared rays, etc., enabling users to enjoy the convenience brought by technology. The continuous development of input devices can be seen from the devel...
