Abstract: Aiming at the characteristics of current smart phone unlocking, this paper proposes a smart phone slide unlock authentication method based on RL-DTW algorithm by using the different biological characteristics of user’s finger sliding screen acceleration. And through the data comparison between the traditional DTW algorithm and the optimized RL-DTW algorithm, it is concluded that the acceleration determination probability value of the RL-DTW algorithm in the aspect of identifying imitators is as high as 93%, which is much higher than 72% of the DTW algorithm. It is well satisfied the user’s demand for the random shape slide screen unlocking of the smart phone.

Keywords: biological characteristics; slide unlock; RL-DTW algorithm
