摘　　要：针对当前智能手机解锁的特点,利用用户手指滑动屏幕加速度不同的生物特性,提出了一种基于RL-DTW算法的智能手机滑动解锁认证方法。并通过对传统DTW算法和优化RL-DTW算法进行数据对比,得出RL-DTW算法在辨别模仿者方面的加速度确定概率值高达93%,远高于DTW算法的72%,很好地满足了用户对智能手机随意形状滑屏解锁的需求。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.
