1、 本发明本实现了移动终端的加密解锁, 实用、 保密性强;
2、 本发明能够减少了对移动终端的物理按键或触摸屏的磨损。 尽管上文对本发明进行了详细说明, 但是本发明不限于此, 本技术领域技术人员 可以根据本发明的原理进行各种修改。 因此, 凡按照本发明原理所作的修改, 都应当 理解为落入本发明的保护范围。 工业实用性 本发明提供的上述技术方案, 可以应用于移动终端的解锁过程中, 采用移动终端 处于锁定状态期间,确定物体接近移动终端屏幕并保持在预定距离范围内的时间长度; 根据所述时间长度, 生成相应的解锁信号; 利用所述解锁信号, 对所述移动终端进行 解锁的技术方案,解决了相关技术中移动终端的物理按键或者触摸屏磨损严重的问题, 提高了移动终端解锁的保密性和实用性。
