Abstract

The invention relates to a method for identity identification of a user of a computer and other terminal devices, in particular to a method for identity identification of users in the network world in the inputting process through a keyboard. The method is characterized in that a method for identification according to the characteristics of a user keystroke is added on the basis of a traditional username/password pair identification mechanism. Due to the adoption of the method, the safety of the system can be enhanced, and the disabled users are prevented from logging in by the identity of a validated user to access the resources in the system; and even if the disabled user knows the username/password pairs of the validated user, since the keystroke characteristic of the validated user is generally different from that of the user corresponding to the username/password pairs, the authentication is not available, therefore, the provided identification method has higher security.

Example Embodiment

[0024] The method proposed by the present invention is mainly improved and strengthened on the basis of the traditional user name/password pair authentication method. Embodiments of the method proposed by the present invention are described in detail below.
[0025] The implementation of the method proposed by the present invention mainly includes three aspects: keystroke information collection, training stage and authentication stage.
[0026] The keystroke information collection includes not only the keystroke information collection during the training phase when the user inputs several specified texts, but also the keystroke information collection during the authentication phase requiring the user to input the specified text.
[0027] The training phase mainly refers to requiring the user to input the specified text for several times. During this process, the user's keystroke model is established by processing the collected keystroke information. In fact, the keystroke models established for different users are different, so we can authenticate user identity through keystroke characteristics.
[0028] The authentication phase refers to the identity authentication that must be performed when users who pass the training phase need to log in to the system and access resources. Mainly, on the basis of user authentication through the user name/password pair, the user is required to enter the specified text. During this process, the user's keystroke information is collected and compared with the user name in the user name/password established during the training phase. The keystroke models of the corresponding users are compared, and according to whether the keystroke characteristics match, it is determined whether the user is indeed the corresponding user in the username/password.
[0029] If, during the authentication phase, the user is rejected, but the user wants to authenticate again, the authentication process can be repeated, starting by asking him to enter a username/password pair.
[0030] In the specific implementation process, the maximum number of failed logins allowed by the same user within a time period (eg, 24 hours) can be set to limit the user's continuous identity authentication and prevent illegal users from passing the authentication through continuous attempts.
