Abstract

The invention discloses an identity recognition method, device and equipment based on keystroke characteristics of mobile equipment and a medium, and the method comprises the steps: extracting the keystroke characteristics of a user whose identity is to be recognized from the keystroke process of logging in the mobile equipment: a leap time sequence, a residence time sequence and a contact coordinate sequence; calculating the variance, Euler distance and Pearson's correlation coefficient between each keystroke feature and the keystroke feature during registration, and obtaining nine feature parameters of user login; inputting the obtained nine characteristic parameters into a pre-trained identity recognition model, and judging whether the identity of the current login user is legal or not according to model output, wherein the identity recognition model is obtained by adopting a feedforward neural network and training based on a plurality of positive and negative samples, and the positive and negative samples are respectively composed of nine characteristic parameters obtained when legal and illegal users log in.

Description

technical field [0001] The invention belongs to the technical field of identification, and in particular relates to an identification method, device, equipment and medium based on keystroke characteristics of a mobile device. Background technique [0002] Currently, in computer systems / platforms that require users to perform login verification, user accounts and passwords are often the most common verification methods. However, this verification method cannot avoid the risk of account theft. Therefore, many systems / platforms have adopted SMS verification, email verification, fingerprint / face recognition and other methods to confirm user identity, but the above methods often have limitations such as information leakage and unsupported equipment. Therefore, some systems / platforms combine keystroke feature recognition modules to ensure user information security. [0003] The keystroke feature in the traditional sense refers to the rhythm of the user typing on the keyboard whe...
