Embodiment Construction

[0016] In order to understand the present invention better, at first briefly introduce existing serial mouse:

[0017] 1. The serial mouse uses four wires in the DB9 connector:

[0018] 2 (RXD: for the positive power supply of the mouse);

[0019] 3 (TXD: used to send data);

[0020] 4 (DTR: for positive power supply, reset and mouse detection);

[0021] 7 (RTS: optional, for positive power supply)

[0022] 2. Simple communication protocol of serial mouse

[0023] (1) The serial data format of the mouse

[0024] The commonly used Microsoft mouse has two buttons and is a mouse system supported by most operating systems. The data format it sends is: baud rate 1200bps, stop bit 1.0, valid data per byte 7 bits, 3 bytes per frame. There are also mice from other companies, such as Logitech, that use mice with 3 buttons (some with a scroll wheel). Logitech has extended the protocol of the Microsoft mouse, using a baud rate of 1200bps, a stop bit of 1.0 bits, 8 bits of valid da...

Abstract

The invention discloses a password protection system, which comprises the following parts: an user boundary UI display unit, a saving unit with the password information and a comparison unit, wherein the password protection system includes a mouse operation dealing modular for sensing the mouse operation information in the password input frame of the UI display unit, analyzing the operation information and getting and outputting the mouse press key type information, the comparison unit is used to compare the output information of the mouse operation dealing modular with the saving password information in the saving unit, if the same, the right password signal is outputted, or the wrong password signal is outputted. The invention discloses a password protection method. The invention simplifies the landing operation, which safeguards the safety of the user' s information.

Description

technical field [0001] The invention relates to computer technology, in particular to a password protection system and method based on mouse operation. Background technique [0002] Nowadays, everyone relies more and more on the mouse when using a computer. Whether it is surfing the Internet or using various software, they all hope to use the mouse to complete the required operations. For example, in the existing password input methods, the password input box must be clicked with a mouse first, and then the password is input through the keyboard. The user is usually accustomed to holding the mouse with the right hand, and also needs the right hand to operate when inputting a numeric password (on the right side of the keyboard) or a mixed alphanumeric password. Like this, every time the user inputs a password, all need to click the mouse first, then let go of the mouse and use the keyboard to input the password, and then return to the mouse to continue the operation. The op...
