图 2为发明基于重力加速的加密方法的流程示意图;
图 3为本发明基于重力加速的解密装置的结构示意图;
图 4为发明基于重力加速的解密方法的流程示意图。 具体实施方式
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。 本发明基于重力加速的加密解密方案的主要思想是: 通过重力加速器 来检测移动终端的运动状态, 确定移动终端的具体动作, 然后获取该动作 对应的字符, 将该字符作为密钥, 对移动终端进行加密或解密。
下面通过具体的实施例来说明本发明的方案。
图 1 所示为本发明基于重力加速的加密装置, 该装置应用于移动终端 中, 包括: 动作识别模块 20、 以及分别与其相连的重力加速器 10和加密模 块 30, 其中:
重力加速器 10, 用于检测移动终端的运动状态, 并输出所述运动状态 的相关数据。
本发明所应用的重力加速器 10具有对矢量运动进行检测、 以及对运动 的角速度进行检测的特点, 因此, 该重力加速器 10不仅可以检测到水平运 动、 垂直运动等直线运动, 还可以检测到正弦线运动、 半圓运动等有角度 的运动。 相应的, 用户在通过运动移动终端进行密钥的输入时, 可以有多 种动作的选择, 提高了用户的体验度。
重力加速器 10检测到移动终端运动状态的同时能够生成运动状态的相 关数据。 运动状态的相关数据是一组数据, 一般包括以下几种特征参数: 三维空间中 x、 y、 z的加速度值及角速度值。
动作识别模块 20, 用于对运动状态的相关数据进行处理, 确定运动状 态对应的动作, 并获取该动作对应的字符, 输出给加密模块 30。
动作识别模块 20获取了移动终端运动状态的相关数据后, 对其进行分 析处理, 先确定当前运动状态具体对应哪个动作: 首先将运动状态的相关 数据进行过滤, 去掉高频部分, 例如在线形动作 (只有 x、 y、 z 的加速度 而不含角速度、 即旋转的运动) 中, 将数据平滑滤波, 剔出其中非正常的 数据, 滤波方法可以用统计平均、 均方差等方式来处理; 对该线性动作的 相关数据进行滤波处理后得到一个二进制的编码值, 其在三维空间可以判 断为直线运动(旋转动作可同理处理, 同时直线与旋转动作也可组合处理); 然后 4艮据该编码值通过查询确定对应的动作。
进一步地, 本发明的加密装置还可以包括一个动作数据库 40, 与动作 识别模块 20相连, 用于存储动作和编码值的对应关系, 如此, 动作识别模 块 20得到运动状态的编码值后, 通过查询动作数据库 40中动作和编码值 的对应关系即可确定与编码值对应的动作。 需要指出的是, 在实际应用中, 运动状态的相关数据转换得到的编码值可能与动作数据库 40存储的多个编 码值相似, 此时, 从动作数据库 40中选择与转换得到的编码值匹配度最高 的编码值 , 从而确定对应的动作。
动作识别模块 20确定了移动终端的动作后, 通过查询获取该动作对应 的字符, 进一步地, 动作数据库 40还用于存储动作与字符的对应关系, 供 动作识别模块 20查询。
需要指出的是, 对于加密过程, 动作与字符的对应关系可以是预先设 置在动作数据库 40中的、 如用户根据自身需要预先设置的、 或者第三方提 供的; 或者, 在运动移动之前, 动作数据库 40没有存储动作与字符的对应 关系, 此时, 可以是运动移动终端时, 对应该动作随机产生的该动作与字 符的对应关系。 不管上述哪种情况, 当移动终端完成一次动作后, 都可以 从动作数据库 40存储的动作与字符的对应关系中查询到该动作对应的字 符。 其中, 一个动作可以对应一个字符, 也可以对应多个字符, 如从左向 右的水平动作 "→" 对应的字符为 "A"、 也可以对应字符 "12"、 也可以对 应字符 "*4@" 等等。
另外, 密钥的长度、 如 6个字符、 4个字符等可以是预先设置的, 也可 以是任意长度。 在输入密钥时, 用户可以多次运动移动终端, 直到所有字 符输入完毕。
这里, 动作识别模块 20可以在获取到所有动作对应的字符后, 再输出 给加密模块 30, 也可以依次将每个动作的字符输出给加密模块 30, 直到所 有的字符输出完毕。
加密模块 30,用于接收动作识别模块 20输出的与移动终端的动作对应 的字符, 将其作为密钥, 对移动终端进行加密。
进一步地, 本发明的加密装置还可以包括密码数据库 50, 与加密模块 30相连, 用于保存移动终端的加密密钥, 以供后续解密时使用。 基于上述加密装置, 本发明基于重力加速的加密方法, 如图 2 所示, 包括如下步骤:
步骤 201 , 检测移动终端的运动状态, 得到运动状态的相关数据。
该步骤的操作由重力加速器来实现,如图 1中对重力加速器 10的描述, 此处不再赘述。
步骤 202,对运动状态的相关数据进行处理,确定运动状态对应的动作, 并获取动作对应的字符。
具体的, 对运动状态的相关数据进行处理, 得到对应的编码值, 并查 询编码值和动作的对应关系, 确定编码值对应的动作; 然后再查询动作和 字符的对应关系, 得到该动作对应的字符。
步骤 203 , 将字符作为密钥对移动终端进行加密。
加密的同时将密钥进行保存, 供后续解密时使用。
图 3 所示为本发明基于重力加速的解密装置, 该装置应用于移动终端 中, 包括动作识别模块 20、 以及分别与其相连的重力加速器 10和解密模块 60, 其中:
重力加速器 10, 用于检测移动终端的运动状态, 并输出所述运动状态 的相关数据。
该重力加速器 10的功能与图 1中重力加速器 10的功能相同, 此处不 再赘述。
动作识别模块 20, 用于对运动状态的相关数据进行处理, 确定运动状 态对应的动作, 并获取该动作对应的字符, 输出给解密模块 60。 该动作识 别模块 20的功能与图 1中动作识别模块 20的功能相同, 此处不再赘述。
该解密装置还包括动作数据库 40,用于存储编码值和动作的对应关系、 以及动作和字符的对应关系, 供动作识别模块 20查询。
需要指出的是, 在解密过程中, 动作识别模块 20需要根据预先设置在 动作数据库 40 中的动作与字符的对应关系, 或者加密时在动作数据库 40 中随机产生的该动作与字符的对应关系, 查询当前动作对应的字符。 这里, 动作识别模块 20可以在获取到所有动作对应的字符后, 再输出给解密模块 60, 也可以依次将每个动作的字符输出给解密模块 60, 直到所有的字符输 出完毕。
解密模块 60,用于接收动作识别模块 20输出的与移动终端的动作对应 的字符, 将其作为密钥, 对移动终端进行解密。
该解密装置进一步包括: 密码数据库 50, 与解密模块 60相连, 用于保 存移动终端的解密密钥; 该解密密码即为加密时输入的密码。
相应的, 解密模块 60, 进一步用于将动作识别模块 20输出的密钥与密 码数据库 50中保存的密钥进行比较, 两者一致时, 对移动终端进行解密。 解密模块 60获取的当前运动移动终端时输入的密钥不一定为正确的密钥, 因此,需要将其与密码数据库 50中保存的解密密钥进行比较,两者一致时, 说明前运动移动终端输入的密钥为正确的密钥, 则对移动终端解密成功。
基于图 3 的解密装置, 本发明提供了一种基于重力加速的解密方法, 如图 4所示, 包括如下步骤:
步骤 401 , 检测移动终端的运动状态, 得到运动状态的相关数据。
该步骤的操作由重力加速器来实现,如图 1中对重力加速器 10的描述, 此处不再赘述。
步骤 402,对运动状态的相关数据进行处理,确定运动状态对应的动作, 并获取动作对应的字符。
具体的, 对运动状态的相关数据进行处理, 得到对应的编码值, 并查 询编码值和动作的对应关系, 确定编码值对应的动作; 然后再查询动作和 字符的对应关系, 得到该动作对应的字符。
步骤 403 , 将字符作为密钥对移动终端进行解密。 当前运动移动终端时输入的密钥不一定为正确的密钥, 因此, 需要将 其与移动终端中保存的解密密钥进行比较, 两者一致时, 说明前运动移动 终端输入的密钥为正确的密钥, 则对移动终端解密成功。
另外, 当釆用本发明的加密装置和方法时, 在解密的过程中也可釆用 常规的输入密钥的方式、 如键盘输入, 此时用户需要知道加密时移动终端 的动作对应的字符; 当釆用常规的密钥输入方式来加密时, 在解密的过程 中也可以釆用本发明的解密装置和方法, 此时用户需要知道密钥 (字符) 对应的动作。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
