Embodiment Construction

[0025] The present invention will be described in detail below through specific embodiments and accompanying drawings.

[0026] Due to the different finger strengths exerted by the user when touching the screen, the contact area and pressure sensed by the touch screen sensor will also be different. Such as figure 1 As shown, different fingers, touch postures, and strengths will all affect the difference in the size of the contact surface. figure 1 In (a), the finger touches the screen lightly, and the contact area is small; figure 1 In (b), the finger presses the screen heavily, and the contact area is larger. The change of this feature can only be perceived by the current user, and it is difficult to be peeped or noticed by a third party, such as figure 2 shown. The present invention utilizes these biometric features to enhance the security of the password authentication system.

Abstract

The invention discloses an anti-peeping code authentication method and an anti-peeping code authentication system based on biological metering characteristics. When a user inputs each code, the biological metering characteristics, namely touch screen pressing degrees of the user, can be authenticated. Furthermore, after the user inputs each code, feel that the user is not peeped can be fed back. The anti-creeping code authentication method and the anti-creeping code authentication system based on biological metering characteristics can effectively prevent peep, enhances code input safety, is convenient and quick to achieve, and can be widely applied to code authentication systems of equipment of mobile phones based on touch screens, automatic teller machine (ATM), tablet computers, access control systems and the like.

Description

technical field [0001] The invention relates to multiple technical fields such as computer software technology, password authentication, touch screen and biometric features, and in particular to an anti-peeping password authentication method based on biometric features, and a system using the method. Background technique [0002] With the popularity of touch screens (such as capacitive touch screens, resistive touch screens, etc.), it is becoming more and more common to input passwords through touch screen analog keyboards (or virtual keyboards), for example, touch screen mobile phones, touch screen ATM machines etc. But like the physical keyboard, this kind of simulated keyboard is also difficult to eliminate the hidden danger of "being peeped by others" when the user enters the password, so that privacy and property security cannot be guaranteed. [0003] Existing anti-peeping technologies include: (1) adding a visual barrier to the password input keyboard, and (2) random...
