Description
本发明涉及信息安全技术领域，尤其涉及一种触摸设备解锁方法和装置。
随着信息化的高速发展，触摸设备的普及，人们越来越重视个人信息的安全。目前，主要通过在触摸设备的操作系统中安装加密软件，通过软件方式实现对触摸设备的加密。但是，如果非法用户对操作系统进行了破解，或者进行了刷机等操作，则会使得加密软件失效，从而非法用户能够对触摸设备进行完全控制。因此，亟需一种在触摸设备的操作系统被破解后，防止非法用户正常使用触摸设备的方法，以保证用户个人信息的安全。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本发明的一个目的在于提出一种触摸设备解锁方法，能有效提高触摸设备的保密性能和安全性。
本发明的第二个目的在于提出一种触摸设备解锁装置。
为了实现上述目的，本发明第一方面实施例提出了一种触摸设备解锁方法，包括：接收用户对触摸设备的解锁操作，所述解锁操作包括输入解锁信息；将所述解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配；以及当所述解锁信息与所述加密信息匹配一致时，控制所述触摸屏控制芯片解锁所述触摸设备。
本发明实施例的触摸设备解锁方法，通过将加密信息保存在触摸屏控制芯片中，能够有效地防止非法用户绕过系统加密正常使用触摸设备，从而保证用户的个人信息安全，提升触摸设备的安全性。
本发明第二方面实施例提出了一种触摸设备解锁装置，包括：接收模块，用于接收用户对触摸设备的解锁操作，所述解锁操作包括输入解锁信息；匹配模块，用于将所述解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配；以及控制模块，用于当所述解锁信息与所述加密信息匹配一致时，控制所述触摸屏控制芯片解锁所述触摸设备。
本发明实施例的触摸设备解锁装置，通过将加密信息保存在触摸屏控制芯片中，能够有效地防止非法用户绕过系统加密正常使用触摸设备，从而保证用户的个人信息安全，提升触摸设备的安全性。
本发明所述的和/或附加的方面和优点从下面结合附图对实施例的描述中将变得明显和容易理解，其中：
图1是根据本发明一个实施例的触摸设备解锁方法的流程图一；
图2是根据本发明一个实施例的触摸设备解锁方法的流程图二；
图3是根据本发明一个实施例的触摸设备解锁方法的流程图三；
图4是根据本发明一个实施例的触摸设备解锁装置的结构示意图一；
图5是根据本发明一个实施例的触摸设备解锁装置的结构示意图二；
图6是根据本发明一个实施例的触摸设备解锁装置的结构示意图三；
图7是根据本发明一个实施例的触摸设备解锁装置的结构示意图四。
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的模块或具有相同或类似功能的模块。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述本发明实施例的触摸设备解锁方法和装置。
图1是根据本发明一个实施例的触摸设备解锁方法的流程图。
如图1所示，触摸设备解锁方法可包括：
S1、接收用户对触摸设备的解锁操作。
其中，解锁操作可包括输入解锁信息。
在相关技术中，主要通过加密软件对触摸设备进行加密，而加密信息均保存在操作系统中，因此很容易通过破解、ROOT、刷机等方式绕过加密软件，从而使得非法用户对触摸设备进行正常操作。
为解决上述问题，在本发明的一个实施例中，用户可先通过操作系统录入加密信息，并将加密信息保存至触摸屏控制芯片中。其中，加密信息可以是用户滑动触摸屏产生的轨迹信息，也可以是密码。密码可以是数字，也可以是字母等字符。该加密信息保存至独立的触摸屏控制芯片中，即使触摸设备的操作系统被破解，非法用户也无法触摸设备进行输入操作，使得触摸设备的可利用价值降低，保证用户个人信息安全。
在当用户需要对触摸设备进行解锁时，用户可输入解锁信息。
S2、将解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配。
在接收到用户对触摸设备的解锁操作之后，可将解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配。例如：如果加密信息为则滑动触摸屏产生的轨迹信息，那么对应的
解锁信息也应该是滑动触摸屏产生的轨迹信息。
S3、当解锁信息与加密信息匹配一致时，控制触摸屏控制芯片解锁触摸设备。
具体地，如果用户输入的解锁信息与保存在触摸屏控制芯片中的加密信息匹配一致，则由触摸屏控制芯片确定触摸设备解锁成功。在解锁成功后，用户可对触摸设备进行控制，使得触摸设备的主控芯片能够执行对应的指令。
另外，如图2所示，本发明实施例的触摸设备解锁方法还可包括步骤S4和步骤S5。
S4、控制触摸屏控制芯片以第一预设时间向主控芯片上报预设信息。
具体地，在将加密信息录入至触摸屏控制芯片，且开启对应的加密功能之后，触摸屏控制芯片可以第一预设时间如每隔1秒钟向触摸设备的主控芯片上报预设信息。与预设信息对应的是主控芯片向触摸屏控制芯片返回的响应信息。预设信息和响应信息主要用于判断触摸设备的操作系统是否处于异常状态。如果触摸屏控制芯片接收到主控芯片返回的响应信息，说明操作系统处于正常状态；如果未接收到响应信息，说明操作系统处于异常状态。其中，异常状态可能是主控芯片与触摸屏控制芯片的通信信号中断、连接故障引起的，也可能是操作系统被破解或刷机引起的。
S5、如果触摸屏控制芯片在第二预设时间内未接收到主控芯片返回的响应信息，则确定操作系统处于异常状态。
具体地，如果触摸屏控制芯片在第二预设时间内如5分钟内，未接收到触摸设备的主控芯片返回的与预设信息对应的响应信息，则说明触摸设备的操作系统处于异常状态，无法向触摸屏控制芯片产生应答。例如：由于触摸屏控制芯片每隔1秒钟都会向主控芯片发送预设信息，而如果操作系统如果处于正常状态，则主控芯片会针对每一个预设信息向触摸屏控制芯片返回一个响应信息。因此，如果触摸屏控制芯片持续了5分钟都没有收到响应信息，则说明操作系统可能被破解，或已刷机，或者主控芯片与触摸屏控制芯片的通信信号中断、主控芯片与触摸屏控制芯片连接故障等，操作系统处于异常状态。
此外，如图3所示，本发明实施例的触摸设备解锁方法还可包括步骤S6。
S6、当触摸设备的操作系统处于异常状态，且触摸设备处于锁屏状态时，如果检测到触摸设备接收到输入操作，则控制触摸屏控制芯片向主控芯片发送干扰信息，以使主控芯片无法执行输入操作对应的指令。
在确定操作系统处于异常状态后，例如操作系统可能被破解的情况下，并且触摸屏控制芯片并未解锁触摸设备时，如果此时检测到有用户对触摸设备进行输入操作，则可控制触摸屏控制芯片向主控芯片发送干扰信息，使得主控芯片无法执行输入操作对应的指令，从而能够有效防止非法用户正常使用触摸设备。
干扰信息可以是对触摸设备的输入操作产生干扰的其他操作信息，例如持续的按键触
发信息。其中，输入操作可以是通过鼠标、键盘等外部命令方式进行输入的操作。也就是说，如果操作系统被破解，非法用户是可以通过鼠标、键盘等非触摸的方式对触摸设备进行操作的。由于加密信息是保存在触摸屏控制芯片中的，因此即使操作系统被破解，也无法绕过加密信息，必须通过输入与之对应的解锁信息才能解锁屏幕，从而正常使用触摸设备。因此，将加密信息保存在触摸屏控制芯片中，有效提高了触摸设备的安全性。
应当理解的是，触摸设备可以是包括触摸屏的电子设备，如智能手机、平板电脑、带触摸屏的一体电脑等。
虽然相关技术中，公开了一种基于安全触控屏控制芯片的安全密码输入系统和方法，主要应用场景为电子支付或电子交易。利用安全触摸屏控制芯片将接收到的系统处理器发送的密码输入界面图像加密并发送给显示屏显示和将触摸屏生成的包含位置信息的电信号转化为真实密码并加密保存，在系统处理器发出读取密码命令时自动将密码解密发送。具体来说，就是在输入支付密码时，利用安全触摸屏控制芯片对密码输入界面图像进行加密，如打乱按键键值与按键坐标信息的对应关系，从而防止支付密码被恶意程序截获。在用户输入正确的密码之后，再对该密码进行解密，生成真实的密码，发送给系统，最后由系统完成对应的密码验证操作，如密码正确支付成功。因此，与本发明的技术方案本质并不相同。
本发明实施例的触摸设备解锁方法，通过将加密信息保存在触摸屏控制芯片中，能够有效地防止非法用户绕过系统加密正常使用触摸设备，从而保证用户的个人信息安全，提升触摸设备的安全性。
为实现上述目的，本发明还提出一种触摸设备解锁装置。
图4是根据本发明一个实施例的触摸设备解锁装置的结构示意图一。
如图4所示，该触摸设备解锁装置可包括：接收模块110、匹配模块120和控制模块130。
接收模块110用于接收用户对触摸设备的解锁操作。
其中，解锁操作可包括输入解锁信息。
匹配模块120用于将解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配。
在接收到用户对触摸设备的解锁操作之后，可将解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配。例如：如果加密信息为则滑动触摸屏产生的轨迹信息，那么对应的解锁信息也应该是滑动触摸屏产生的轨迹信息。
控制模块130用于当解锁信息与加密信息匹配一致时，控制触摸屏控制芯片解锁触摸设备。
具体地，如果用户输入的解锁信息与保存在触摸屏控制芯片中的加密信息匹配一致，则由触摸屏控制芯片确定触摸设备解锁成功。控制模块130控制触摸屏控制芯片解锁触摸设备。在解锁成功后，用户可对触摸设备进行控制，使得触摸设备的主控芯片能够执行对应的指令。
另外，如图5所示，本发明实施例的触摸设备解锁装置还可包括保存模块140。
保存模块140用于在将解锁信息与加密信息进行匹配之前，通过操作系统录入加密信息，并将加密信息保存至触摸屏控制芯片中。在本发明的一个实施例中，用户可先通过操作系统录入加密信息，保存模块140可将加密信息保存至触摸屏控制芯片中。其中，加密信息可以是用户滑动触摸屏产生的轨迹信息，也可以是密码。密码可以是数字，也可以是字母等字符。该加密信息保存至独立的触摸屏控制芯片中，即使触摸设备的操作系统被破解，非法用户也无法触摸设备进行输入操作，使得触摸设备的可利用价值降低，保证用户个人信息安全。
此外，如图6所示，本发明实施例的触摸设备解锁装置还可包括上报模块150和确定模块160。
上报模块150用于控制触摸屏控制芯片以第一预设时间向主控芯片上报预设信息。具体地，在将加密信息录入至触摸屏控制芯片，且开启对应的加密功能之后，上报模块150可控制触摸屏控制芯片以第一预设时间如每隔1秒钟向触摸设备的主控芯片上报预设信息。与预设信息对应的是主控芯片向触摸屏控制芯片返回的响应信息。预设信息和响应信息主要用于判断触摸设备的操作系统是否处于异常状态。如果触摸屏控制芯片接收到主控芯片返回的响应信息，说明操作系统处于正常状态；如果未接收到响应信息，说明操作系统处于异常状态。其中，异常状态可能是主控芯片与触摸屏控制芯片的通信信号中断、连接故障引起的，也可能是操作系统被破解或刷机引起的。
确定模块160用于当触摸屏控制芯片在第二预设时间内未接收到主控芯片返回的响应信息时，确定操作系统处于异常状态。
具体地，如果触摸屏控制芯片在第二预设时间内如5分钟内，未接收到触摸设备的主控芯片返回的与预设信息对应的响应信息，则说明触摸设备的操作系统处于异常状态，无法向触摸屏控制芯片产生应答。例如：由于触摸屏控制芯片每隔1秒钟都会向主控芯片发送预设信息，而如果操作系统如果处于正常状态，则主控芯片会针对每一个预设信息向触摸屏控制芯片返回一个响应信息。因此，如果触摸屏控制芯片持续了5分钟都没有收到响应信息，则说明操作系统可能被破解，或已刷机，或者主控芯片与触摸屏控制芯片的通信信号中断、主控芯片与触摸屏控制芯片连接故障等，操作系统处于异常状态。
此外，如图7所示，本发明实施例的触摸设备解锁装置还可包括发送模块170。
发送模块170用于当触摸设备的操作系统处于异常状态，且触摸设备处于锁屏状态时，如果检测到触摸设备接收到输入操作，则控制触摸屏控制芯片向主控芯片发送干扰信息，以使主控芯片无法执行输入操作对应的指令。
在确定操作系统处于异常状态后，例如操作系统可能被破解的情况下，并且触摸屏控制芯片并未解锁触摸设备时，如果此时检测到有用户对触摸设备进行输入操作，则发送模块170可控制触摸屏控制芯片向主控芯片发送干扰信息，使得主控芯片无法执行输入操作对应的指令，从而能够有效防止非法用户正常使用触摸设备。
干扰信息可以是对触摸设备的输入操作产生干扰的其他操作信息，例如持续的按键触发信息。其中，输入操作可以是通过鼠标、键盘等外部命令方式进行输入的操作。也就是说，如果操作系统被破解，非法用户是可以通过鼠标、键盘等非触摸的方式对触摸设备进行操作的。由于加密信息是保存在触摸屏控制芯片中的，因此即使操作系统被破解，也无法绕过加密信息，必须通过输入与之对应的解锁信息才能解锁屏幕，从而正常使用触摸设备。因此，将加密信息保存在触摸屏控制芯片中，有效提高了触摸设备的安全性。
应当理解的是，触摸设备可以是包括触摸屏的电子设备，如智能手机、平板电脑、带触摸屏的一体电脑等。
本发明实施例的触摸设备解锁装置，通过将加密信息保存在触摸屏控制芯片中，能够在触摸设备的操作系统被破解后，有效地防止非法用户绕过系统加密正常使用触摸设备，从而保证了用户的个人信息安全，提升了触摸设备的安全性。

- 一种触摸设备解锁方法，其特征在于，包括以下步骤：接收用户对触摸设备的解锁操作，所述解锁操作包括输入解锁信息；将所述解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配；以及当所述解锁信息与所述加密信息匹配一致时，控制所述触摸屏控制芯片解锁所述触摸设备。
- 如权利要求1所述的方法，其特征在于，还包括：控制所述触摸屏控制芯片以第一预设时间向主控芯片上报预设信息；如果所述触摸屏控制芯片在第二预设时间内未接收到所述主控芯片返回的响应信息，则确定所述触摸设备的操作系统处于异常状态，其中，所述响应信息与所述预设信息相对应。
- 如权利要求2所述的方法，其特征在于，还包括：当所述触摸设备的操作系统处于所述异常状态，且所述触摸设备处于锁屏状态时，如果检测到所述触摸设备接收到输入操作，则控制所述触摸屏控制芯片向所述主控芯片发送干扰信息，以使所述主控芯片无法执行所述输入操作对应的指令。
- 如权利要求3所述的方法，其特征在于，所述输入操作为通过外部命令方式进行输入的操作。
- 如权利要求1所述的方法，其特征在于，在将所述解锁信息与所述加密信息进行匹配之前，还包括：通过操作系统录入所述加密信息，并将所述加密信息保存至所述触摸屏控制芯片中。
- 如权利要求5所述的方法，其特征在于，所述加密信息包括轨迹信息或密码。
- 一种触摸设备解锁装置，其特征在于，包括：接收模块，用于接收用户对触摸设备的解锁操作，所述解锁操作包括输入解锁信息；匹配模块，用于将所述解锁信息与保存在触摸屏控制芯片中的加密信息进行匹配；以及控制模块，用于当所述解锁信息与所述加密信息匹配一致时，控制所述触摸屏控制芯片解锁所述触摸设备。
- 如权利要求7所述的装置，其特征在于，还包括：上报模块，用于控制所述触摸屏控制芯片以第一预设时间向主控芯片上报预设信息；确定模块，用于当所述触摸屏控制芯片在第二预设时间内未接收到所述主控芯片返回的响应信息时，确定操作系统处于异常状态，其中，所述响应信息与所述预设信息相对应。
- 如权利要求8所述的装置，其特征在于，还包括：发送模块，用于当所述触摸设备的操作系统处于所述异常状态，且所述触摸设备处于锁屏状态时，如果检测到所述触摸设备接收到输入操作，则控制所述触摸屏控制芯片向所述主控芯片发送干扰信息，以使所述主控芯片无法执行所述输入操作对应的指令。
- 如权利要求9所述的装置，其特征在于，所述输入操作为通过外部命令方式进行输入的操作。
- 如权利要求7所述的装置，其特征在于，还包括：保存模块，用于在将所述解锁信息与所述加密信息进行匹配之前，通过操作系统录入所述加密信息，并将所述加密信息保存至所述触摸屏控制芯片中。
- 如权利要求11所述的装置，其特征在于，所述加密信息包括轨迹信息或密码。
