Identity authentication code generation system and method based on user input habits

The invention relates to an identity authentication code generation system and method based on user input habits, and the identity authentication code generation method comprises the steps that a userinput habit collection module collects the user input habits of a user, and the user input habits comprise historical search words and/or browsing records, and a user input habit graph is generated according to the user input habits; a comparison data storage module generates a comparison data graph according to the content of the system; and when an identity authentication code generation modulereceives an identity authentication request of a user input account, one user input habit graph and one or more comparison data graphs are randomly selected to generate a group of identity authentication codes, and the identity authentication codes are pushed to a user side display interface to be displayed. The identity authentication code is generated according to the usual input habit of the user, and the user can comp
