Description
一种键盘的设置方法和装. 技术领域
本发明涉及计算机技术领域, 尤其涉及一种处理计算机键盘的设置 方法和装置。 背景技术
科技的发展使得终端的应用越来越广泛, 例如, 使用计算机办公, 使用平板电脑随时随地的看电影和玩游戏, 以及使用手机与其他人通讯 等。 随着终端应用的发展, 保密性的要求也越来越高。 例如, 手机需要 输入密码才能使用, 终端中的一些重要文件也需要输入密码才能查看。
终端中通常是在屏幕的固定区域设置虚拟键盘来输入密码的, 所述 虚拟键盘中各个按键的位置和键值 (即输出内容) 是固定的。 例如, 以 屏幕的左上角为原点, 向右为 X轴方向, 向下为 y轴方向。 区域( 10, 10 , 30, 30 ) 为按键 1 , 输出内容为 " 1 " ; 区域(40 , 10, 60 , 30 ) 为 按键 2, 输出内容为 "2" 等。 在输入密码时, 只要点击区域就可以输入 相应的内容, 最终完成密码的输入。
因此就出现了一些密码破解软件, 利用键盘的固定性来破解密码。 该密码破解软件可以获取虚拟键盘在屏幕中的位置, 以及虚拟键盘中各 按键的位置和键值,然后通过 click命令实现对屏幕中区域即按键的点击, 例如, 依次输入命令序列 (40 , 10 , 60 , 30 , click ) , ( 10 , 10 , 30 , 30 , click ) 就相当于输入了字符串 21。 若密码刚好是 21 , 则破解成功, 若密码不是 21 , 则破解失败, 该密码破解软件可以调整命令序列, 继续 尝试破解密码。
通常在终端中是对时间进行限制以起到保密的作用, 例如, 可以设 置密码的失败阈值, 当密码输入的失败次数达到失败阈值时, 就会进行 时间限制, 如对密码的输入锁定一段时间, 例如 5分钟, 5分钟以后才能 重新尝试输入密码。 但是, 这种时间限制通常是对人工的输入而言的, 一个人在输入密码时, 有很多不可估量的因素导致他在尝试一段时间后, 可能会停止尝试, 从而起到了密码保护的作用。
而针对密码破解软件, 它在尝试破解密码时不存在不可估量的因素,
一旦使用密码破解软件去破解密码, 它可以忽略时间限制的问题, 在可 以输入密码的时间内不断地调整命令序列来进行尝试, 直到密码破解成 功为止。
因此, 本领域技术人员迫切解决的一个技术问题是, 提出一种虚拟 键盘的设置方法, 可以对虚拟键盘中的各个按键进行调整, 以防止密码 破解软件通过不断地尝试输入命令序列的方法来破解密码。 发明内容
鉴于上述问题, 提出了本发明以便提供一种克服上述问题或者至少 部分地解决或者减緩上述问题的虚拟键盘的设置方法和装置, 可以对虚 拟键盘中的各个按键进行调整, 以防止密码破解软件通过不断地尝试输 入命令序列的方法来破解密码。

在重置后的键盘布局中, 接收由所选的按键键值构成的字符串以继 续执行密码校验。
根据本发明的另一个方面, 提供了一种虚拟键盘的设置装置, 包括: 接收模块, 适于在当前键盘布局中, 接收由所选的按键键值构成的 字符串, 执行密码校验;
检验通过模块, 适于当检测到所述字符串与预设密码匹配时, 对所 述字符串的密码校验通过;

触发所述接收模块, 在重置的键盘布局中, 接收由所选的按键键值 构成的字符串以继续执行密码校验。
根据本发明的又一个方面, 提供了一种计算机程序, 包括计算机可 读代码, 当所述计算机可读代码在服务器上运行时, 导致所述服务器执
行根据权利要求 1-8中的任一个所述的虚拟键盘的设置方法。
根据本发明的再一个方面, 提供了一种计算机可读介质, 其中存储 了如权利要求 12所述的计算机程序。
本发明的有益效果为:
首先, 本发明可以在当前键盘布局中, 接收由所选的按键键值构成 的字符串, 然后在所述字符串与预设密码不匹配时, 重置键盘布局, 更 改按键键值在虚拟键盘中对应的按键位置。 则密码破解软件无法正确的 获取键盘在屏幕中的按键位置, 也无法正确的获取键盘中各按键键值。 在密码破解软件尝试输入密码时, 可能输入之前曾输入过的字符串, 也 可能无法输入字符串, 使得密码破解软件破解失败, 从而使需密码保护 得终端、 终端中文件和终端中的应用更加安全, 密码可以起到其作用。

再次, 本发明还包括键盘布局列表、 按键区域列表和按键内容列表, 通过上述的列表可以快速的获取按键区域列表、 按键位置和按键键值, 快速的构成各按键位置与按键键值的对应关系, 从而快速的构成重置的 键盘布局。
上述说明仅是本发明技术方案的概述, 为了能够更清楚了解本发明 的技术手段, 而可依照说明书的内容予以实施, 并且为了让本发明的上 述和其它目的、 特征和优点能够更明显易懂, 以下特举本发明的具体实 施方式。 附图说明

下面结合附图和具体的实施方式对本发明作进一步的描述。
现有技术中, 虚拟键盘的布局是固定的, 即终端中输入密码的区域 和位置是固定的, 因此, 可以设置密码破解软件, 利用键盘的固定性来 破解密码。 所述密码破解软件获取键盘在屏幕中的位置, 以及键盘中各 按键的位置和键值后, 可以通过不断调整命令序列来尝试输入密码, 直 到密码破解成功为止。
本发明提供一种键盘的设置方法, 可以自动更改键盘的布局, 更改 按键键值在虚拟键盘中对应的按键位置, 使得密码破解软件无法获知虚 拟键盘在屏幕中的位置, 以及虚拟键盘中的按键键值, 从而无法尝试破 解密码。
参照图 1 , 给出了本发明实施例所述一种键盘的设置方法流程图。 参照图 2, 给出了本发明实施例所述键盘布局示意图。
其中, a为第一种键盘布局, al为第一种键盘布局中的屏幕部分, a2 为第一种键盘布局中的按键位置部分, 其中的 "0" " 1 " ... ... "9" "*" "#" 分别代表一个按键位置。
b为第一种键盘布局, bl为第一种键盘布局中的屏幕部分, b2为第 一种键盘布局中的按键位置部分, 其中的 "0" " 1 " ... ... "9" "*" "#" 分别代表一个按键位置。
下面结合图 2具体论述本实施例。
步骤 101 ,在当前键盘布局中,接收由所选的按键键值构成的字符串, 执行密码校验;
随着终端应用的发展, 保密性的要求也越来越高。 例如, 手机需要
输入密码才能使用, 终端中的一些重要文件也需要输入密码才能查看, 终端中的有些应用需要输入密码才能使用。
在提示用户输入密码后, 会显示密码输入界面, 用户本次输入密码 时, 所显示的密码输入界面就是当前键盘布局, 假设图 2 中的第一种键 盘布局 a为当前键盘布局。用户可以在当前键盘布局下输入密码,如 1234 , 即分别点击当前键盘布局中的按键位置 " 1 " "2" "3" "4" , 可以获 取按键键值构成的字符串 " 1234" 。
则在当前键盘布局中, 接收由所选的按键键值构成的字符串, 图 2 中, 按键位置 " 1 " "2" "3" "4" 分别对应按键键值 1234, 则输入字 符串 " 1234" 作为本次输入的密码, 而后执行密码校验过程。
步骤 102, 检测所述字符串与预设密码是否匹配;
所述预设密码可以是当前所设置的密码, 如, 进入应用 1 时, 预设 密码是为应用 1 配置的密码, 又如, 使用手机时, 预设密码是为手机配 置的解锁密码。 密码验证通过才能进入设置了密码的项目, 如应用, 手 机等。
在密码校验过程中, 要检测所述字符串与预设密码是否匹配, 即验 证输入的密码是否正确。 如预设密码是 1234 , 则匹配, 如预设密码不是 1234, 则不匹配。
若是, 即检测到所述字符串与预设密码匹配, 则后续执行步骤 103 ; 若否, 即检测到所述字符串与预设密码不匹配, 则后续执行步骤 104。
步骤 103 , 对所述字符串的检验通过;
若所述字符串与预设密码匹配, 即密码输入正确, 则对所述字符串 的检验通过, 用户根据不同的应用场景执行后续的操作, 例如, 可以使 用终端, 又如可以打开并查看文件等。
步骤 104, 重置键盘布局, 更改按键键值在虚拟键盘中对应的按键位 置。
本发明中, 为了防止密码破解软件通过不断地尝试输入命令序列的 方法来破解密码, 此后会更改键盘布局。
实际上, 终端的显示界面可以显示出各个按键, 则用户选择按键可 以输入该按键的按键键值, 即在按键布局中存储有各个按键位置, 各按 键位置和按键键值是具有对应关系的, 通过选择按键位置可以输入按键 键值。 因此在重置键盘布局时, 可以更改按键键值在虚拟键盘中对应的
按键位置。
例如, 将图 2中第一种键盘布局 a的 al和 a2位置调换, 即将第一种 键盘布局中的屏幕部分和按键位置部分上下颠倒, 构成重置的键盘布局。 重置前按键键值 " 1 " 对应的按键位置为 ( 10, 100, 30, 120 ) , 重置后 按键键值 " 1 " 对应的按键位置为 ( 10, 10 , 30 , 30 ) 。
又如, 将图 2中第一种键盘布局 a中, 按键位置部分 al中第一排和 第二排的按键键值调换, 即原本对应按键键值 " 1 " 的按键位置, 重置后 对应按键键值 "4" , 以此类推, 构成重置的键盘布局。
在重置后的键盘布局中, 接收由所选的按键键值构成的字符串以继 续执行密码校验。
当重置键盘布局后, 在终端中所显示的密码输入界面就是重置后的 键盘布局,也即将重置后的键盘布局为当前键盘布局,然后返回步骤 101 , 接收由所选的按键键值构成的字符串以继续执行密码校验, 具体的, 可 以重复上述步骤, 直至密码校验通过。
键盘布局重置后, 后续返回步骤 101 , 可以重新接收字符串, 进行密 码输入和验证。 键盘布局更改后, 密码破解软件无法正确的获取键盘在 屏幕中的位置, 也就无法正确的获取按键键值。 则密码破解软件在不断 地尝试输入密码时, 可能输入之前曾输入过的字符串, 也可能无法输入 字符串。
综上所述, 本发明可以在当前键盘布局中, 接收由所选的按键键值 构成的字符串, 然后在所述字符串与预设密码不匹配时, 重置键盘布局, 更改按键键值在虚拟键盘中对应的按键位置。 则密码破解软件无法正确 的获取屏幕中的按键位置, 也无法正确的获取按键键值。 在密码破解软 件尝试输入密码时, 可能输入之前曾输入过的字符串, 也可能无法输入 字符串, 使得密码破解软件破解失败, 从而使需密码保护得终端、 终端 中文件和终端中的应用更加安全, 密码可以起到其作用。
可选的, 检测到所述字符串与预设密码不匹配之后, 还包括: 检测输入次数是否达到失败阈值, 若达到阈值, 则重置键盘布局, 否则, 重新接收字符串。
若所述字符串与预设密码不匹配, 检测当前键盘布局下输入次数是 否达到失败阈值, 其中, 若所述输入的字符串与预设密码匹配, 则所述 字符串会直接通过验证, 不需要记录次数, 因此, 所述输入次数可以是
当前键盘布局中所述输入的字符串与预设密码不匹配的次数。 所述失败 阈值是一种键盘布局中字符串输入的最大失败次数, 例如, 设失败次数 为 3 , 则检测在当前键盘布局下, 输入次数是否达到 3。
若是, 即输入次数达到失败阈值, 则需要重置键盘布局, 如执行上 例步骤 105 操作; 若否, 即输入次数未达到失败阈值, 则对继续检测后 续输入的字符串后的输入次数是否超过失败阈值。
现有技术中, 若输入次数达到失败阈值, 现有技术就会进行时间限 制, 如对密码的输入锁定一段时间, 例如 5分钟, 5分钟以后才能重新尝 试输入密码。 但若密码破解软件在锁定时间过后继续尝试输入密码, 则 最终密码会被破解。
而本发明在输入次数达到失败阈值后, 可以重置键盘布局, 使得密 码破解软件无法获取到正确的按键键值, 防止密码被破解, 保护了终端 的安全。 可选的, 所述更改按键键值在虚拟键盘中对应的按键位置, 包括:
1 )保留虚拟键盘中各按键位置, 更改各按键位置对应的按键键值。 在重置键盘布局时, 不改变终端中所显示的各个按键的位置, 但改 变每个位置所对应的按键键值, 即可以保留虚拟键盘中各个按键位置, 而更改各按键位置对应的按键键值, 以实现键盘布局的重置。
如上例中,按键位置部分 al不变,将按键位置部分 al中第一排和第 二排的按键键值调换, 即原本对应按键键值 " 1 " 的按键位置 ( 10, 100 , 30 , 120 ) , 重置后对应按键键值 "4" , 以此类推, 构成重置的键盘布 局。
2 ) 改变虚拟键盘中各按键位置, 并为各按键位置配置按键键值。 在重置键盘布局时, 也可以改变终端中所显示的各个按键的位置, 再为各个位置配置上相应的按键键值, 即改变虚拟键盘中各按键位置, 并为每一个按键位置配置唯一的按键键值。
如上例中, 将图 2中第一种键盘布局 a的 al和 a2位置调换, 构成重 置的键盘布局。 重置前按键键值 " 1 " 对应的按键位置为 ( 10 , 100, 30 , 120 ) , 重置后按键键值 " 1 " 对应的按键位置为 ( 10, 10, 30, 30 ) 。
因此,若釆用上述 1 )所述的方法,重置的键盘布局中按键位置未变, 但各按键位置对应的按键键值变化了, 因此, 密码破解软件选择按键位
置后, 预期输入的按键键值和实际输入的按键键值会发生变化。 如 1 )的 例子中, 密码破解软件选择按键位置 ( 10 , 100 , 30 , 120 ) 以期输入按 键键值 " 1 " 时, 实际的按键键值却是 "4" 。
而釆用上述 2 )所述的方法,重置的键盘布局中各按键的位置改变了, 因此, 密码破解软件选择按键位置可能出现无法输入的问题。 如 2 )的例 子中密码破解软件选择按键位置 ( 10 , 100 , 30 , 120 ) 以期输入按键键 值 " 1 " 时, 而此时键盘布局在坐标 ( 10 , 100, 30, 120 ) 上是不存在按 键的, 因此无法输入按键键值。
当然, 2 ) 所述的方法也可能出现密码破解软件选择按键位置后, 预 期输入的按键键值和实际输入的按键键值不同的情况, 此处为——列举, 不应理解为是对本发明的限制。
综上所述, 本发明可以保留虚拟键盘中各按键位置, 更改各按键位 置对应的按键键值, 或, 改变虚拟键盘中各按键位置, 并为各按键位置 配置按键键值。 方法灵活多变, 并且通过这两种方法可以快速的重置键 盘布局, 从而实现在不影响用户输入的情况下, 起到安全保护的作用。
可选的, 在按键区域列表中保存键盘布局中的各个按键位置; 在按 键区域列表组中保存各种按键区域列表; 在按键内容列表中保存按键键 值; 在按键布局列表内保存选定的按键区域列表中各按键位置与按键键 值的对应关系。
为了更快速地更改键盘布局, 本发明可以预置按键区域列表, 所述 按键区域列表适于保存键盘布局中的各个按键位置, 也即保存屏幕中所 显示的按键位置, 每个按键位置对应于屏幕中的一个位置, 则屏幕中的 所有按键位置可以构成一种按键区域列表。例如, 图 2中 a和 b就是由两 种不同的按键区域列表构成的, 假设: a所显示的是第一种按键区域列表 中的按键位置, b所显示的是第二种按键区域列表中的按键位置。 又如, 图 2中 a所显示的是第一种按键区域列表中的按键位置,若从中任意选择 一个按键位置, 在保持其他按键位置不变的情况下, 将所选择的按键位 置更改到屏幕中的其他位置, 则可构成一种新的按键区域列表。
则选定某一种按键区域列表, 同上例, 图 2中 a为当前键盘布局, 则 当前键盘布局选定的是第一种按键区域列表, 因此若要更改按键位置, 可以选择另一种按键区域列表, 其与当前键盘布局所选定的按键区域列 表不同, 例如选择图 2中 b所选定的第二种按键区域列表。
然后, 在所选的按键区域列表中随机获取一个按键位置, 然后可以 选择一个按键位置对应的按键键值, 共同保存所述按键位置和对应的按 键键值。
其中, 更改按键位置时, 可以预先记录所述当前键盘布局中按键位 置对应按键键值的顺序, 则选择按键位置后可以依然按照所述顺序为按 键位置配置按键键值。 例如, 一种按键区域列表中的按键位置是与图 2 中 a所示的按键位置部分上下颠倒的,若选择该按键区域列表, 则若按照 所述顺序为按键位置配置按键键值, 则在屏幕中显示的效果可以是 al和 a2对调。
所述按键区域列表, 用以保存屏幕中显示的按键位置, 可以形如表 1
表 1
表 1 仅为按键区域列表的一种形式, 具体实施中还可以包含其他形 式, 不应理解为是对本发明的限制。
其中, 屏幕中的位置可以为屏幕中的一个坐标位置, 例如以左上角 为原点, 向右为正 X轴, 向下为正 y轴。
实际处理中, 可以预先对按键区域列表中各按键位置编号进行区分, 例如, 按照从左到右, 从上到下的顺序编号。
例如, 在按键区域列表中, 图 2中 a所显示的按键键值 " 1 " 对应的 按键位置为 yl , 按键键值 "*" 对应的按键位置为 y4 , 按键键值 "4" 对 应的按键位置为 y5等。 又如, b所显示的按键键值 " 1 " 对应的按键位置 为 yl , 按键键值 "*" 对应的按键位置为 12, 按键键值 "4" 对应的按 键位置为 y3等。
则在按键区域列表中可以记录各个按键位置的编号, 则通过所有按 键位置就可以唯一构成一种按键区域列表。 因此, 在选择按键区域列表 后, 可以为每个编号的按键位置配置一个按键键值, 即为终端中的一个 坐标位置配置了输出值 (即按键键值) 。
若要保留虚拟键盘中各按键位置, 更改按键位置对应的按键键值,
则可以保留当前键盘布局中的按键区域列表, 而针对每一个按键位置, 随机获取一个按键键值, 建立所述按键位置和所述按键键值的对应关系, 即为所述按键位置配置上该按键键值。
例如, 不更改选定的按键区域列表,如仍然是图 2中 a所选定的按键 区域列表, 则可以对原有按键键值 " 1 " 对应的按键位置, 随机获取一个 按键键值, 此时获取与之前相同的按键键值 (即更改前, 当前键盘布局 中按键位置对应的按键键值) 的概率是 1/12, 相同的概率比较低, 而所 有按键位置与之前的按键键值都相同的概率就是 1/ ( 12 ) 12, 概率非常 低, 可以认为不会发生, 当然若键盘中的按键位置更多, 则概率对更低。 此时为了更加确保按键位置和之前的按键键值不会重合, 还可以预先记 录更改前, 当前键盘布局中按键位置对应的按键键值, 则随机获取一个 按键键值后, 与记录内容进行比较, 不相同后, 就可以建立所述按键位 置和所述按键键值的对应关系, 若相同, 则可以重新选择。
本发明还可以包括键盘布局列表, 其中包括所要显示的键盘布局中 的按键位置和对应的按键键值, 在键盘布局列表中保存选定的按键区域 列表中各按键位置与按键键值的对应关系, 如表 2所示:
表 2
表 2 仅为键盘布局列表的一种形式, 具体实施中还可以包含其他形 式, 不应理解为是对本发明的限制。
实际处理中, 键盘布局列表中可以包括选定的按键区域列表, 并且 保存选定的按键区域列表中各编号对应的按键位置, 和按键键值的对应 关系。
如图 2中 a所显示的按键键值 " 1 " 对应的按键位置为 yl , 按键键值 "*" 对应的按键位置为 y4, 按键键值 "4" 对应的按键位置为 y5等。 又如, b所显示的按键键值 " 1 "对应的按键位置为 yl , 按键键值 "*" 对 应的按键位置为 12 , 按键键值 "4" 对应的按键位置为 y3等。
所述按键区域列表适于保存屏幕中所显示的按键位置, 因此按键位 置在屏幕中的不同位置, 对应于不同的按键区域列表, 则本发明中包含
很多种按键区域列表, 因此可以将所有按键区域列表构成按键区域列表 组, 在更改键盘布局是, 可以从所述按键区域列表组中选择按键区域列 表。
本发明中还可以包括按键内容列表, 包括按键键值和按键的显示内 容, 如表 3所示:
可选的, 所述按键内容列表中还包括按键的显示内容, 所述按键的 显示内容与按键键值——对应。
在键盘布局中每一个按键位置都对应着按键的显示内容, 通过所述 显示内容可以了解该按键位置对应的按键键值, 如图 2 中按键位置部分 所显示的 " 1 " "2" 等, 所述按键的显示内容与按键键值是相同的, 如 图 2中显示 " 1 " 的按键位置对应的按键键值为 1。 当然, 也可能出现所 述按键的显示内容与按键键值不相同的情况, 本发明对此不做限定。
参照图 3 ,给出了本发明优选实施例所述一种键盘的设置方法中第一 种键盘布局更改流程图。
可选的, 保留虚拟键盘中各按键位置, 更改各按键位置对应的按键 键值, 包括:
步骤 301 ,清空键盘布局列表内选定的按键区域列表中各按键位置与 按键键值的对应关系;
若要保留虚拟键盘中各按键位置, 更改各按键位置对应的按键键值, 也即更改按键位置对应的按键键值, 可以不更改选定的按键区域列表, 因此可以清空键盘布局列表内, 选定的按键区域列表中各中按键区域与 按键键值的对应关系。
则此时键盘布局列表中可以包括按键区域列表, 和该按键区域列表 中的各个按键位置。
步骤 302,针对键盘布局列表内选定的按键区域列表中的一个按键区
域, 随机从按键内容列表中获取一个按键键值;
然后针对键盘布局列表内选定的按键区域列表中的一个按键区域, 随机从按键内容列表中获取一个按键键值。 由于按键区域的数量比较多, 因此随机获取按键键值时, 所构成键盘布局与当前键盘布局完全一致的 概率非常低, 即所有按键区域与之前的按键键值都相同的概率非常低。
此时为了更加确保按键区域和之前的按键键值不会重合, 还可以预 先记录更改前, 当前键盘布局中按键区域对应的按键键值, 则随机获取 一个按键键值后, 与记录内容进行比较, 不相同后, 就可以建立所述按 键区域和所述按键键值的对应关系, 若相同, 则可以重新选择。
步骤 303 , 建立所述按键区域与所述按键键值的对应关系, 并保存到 键盘布局列表中, 构成重置的键盘布局。
然后建立所述按键区域与所述按键键值的对应关系, 即为每一个按 键区域配置上相应的按键键值, 然后将所述对应关系保存到键盘布局列 表中, 构成重置的键盘布局。
参照图 4,给出了本发明优选实施例所述一种键盘的设置方法中第二 种键盘布局更改流程图。
可选的, 改变虚拟键盘中各按键位置, 并为各按键位置配置按键键 值,包括:
步骤 401 , 清空键盘布局列表;
若要改变虚拟键盘中各按键位置, 则可以情况键盘布局列表, 即键 盘布局列表中没有记录选定的按键区域列表, 也没有个按键位置和按键 键值的对应关系。
步骤 402, 从按键区域列表组中选择一种按键区域列表, 其与当前键 盘布局所选定的按键区域列表不同;
然后, 从按键区域列表组中选择一种按键区域列表, 其与当前键盘 布局所选定的按键区域列表不同。 例如, 当前键盘布局所选定的按键区 域列表为第一种按键区域列表, 则此时可以选择除第一种按键区域列表 以外的任——种按键区域列表, 如第二种按键区域列表。
步骤 403 , 从所选的按键区域列表中随机获取一个按键位置; 然后可以从所选的按键区域列表中随机获取一个按键位置, 例如, 选择第二种按键区域列表, 从第二种按键区域列表中随机获取一个按键 位置, 如选择按键位置的编号 y2。
步骤 404, 从按键内容列表中随机获取一个按键键值;
由于此时各按键位置变化了, 因此还要为每个按键位置配置一个按 键键值, 因此在选择好按键区域列表和所选的按键区域列表中的一个按 键位置后, 可以随机从按键内容列表中获取一个按键键值。
