System and user pattern authentication method for prevention of shoulder and shoulder surfing attacks of mobile devices

摘要

Problem to be solved: to provide a pattern authentication method for preventing smudge and shoulder surfing attacks of mobile devices.The method includes pattern registration steps and pattern authentication steps.The pattern registration step isThe input of the pattern authentication device receives the pattern from the user andThe matching part matches the code value corresponding to the pattern input from the user.To store in the storage andThe KDI (key discovery ID) generator matches the code value and the quantum random number table containing the quantum random number generated by the quantum random number generatorIncludes generating a user KDI (key recommendation ID).Diagram
