本申请是以CN申请号为201711042241.2，申请日为2017年10月31日的申请为基础，并主张其优先权，该CN申请的公开内容在此作为整体引入本申请中。
本公开涉及智能终端技术领域，特别是一种二维码信息读取、生成方法和装置。
随着互联网及智能移动设备的逐渐普及，二维码正广泛的深入人们的日常生活中，现在二维码在共享单车、社交网络、移动支付、食品安全追溯、快递等应用场景中随处可见。众所周知二维码的面积一般比较小，如何利用这有限之地使二维码图像存储更多信息是一个值得思考的问题。
相关二维码的扩充的方案主要包括以下几种：
1、三维码，即利用颜色信息或其他信息(比如形状等)将一个点由二进制信息变成多进制，从而扩充二维码的容量。
2、增加二维码的面积和单位面积内点的个数。
3、二维码指向一个互联网链接，通过链接访问服务器上的更多内容。
发明内容
发明人发现，相关的二维码扩充方案中，三维码颜色信息太多种，若要做到统一标准很难，另外如果将一个点的信息从二进制扩充到多进制，编码规则相应的也需要变化，原有的扫描设备需要做很多修改才能使用；增加二维码的面积和单位面积内点的个数会导致二维码占用空间增大或点的密度增大，不容易识别；通过互联网链接访问网页的方式不够便捷，且会在断网的情况下失效。
本公开的一个目的在于实现不同用户扫描相同二维码获取不同信息，提高二维码的信息容量。
根据本公开的一些实施例的一个方面，提出一种二维码信息读取方法，包括：获取用户扫描的二维码图像信息和用户身份信息；根据用户身份信息获取二维码图像中 的隐藏二维码图像；获取与隐藏二维码图像相关联的数据信息。
在一些实施例中，二维码图像中隐藏有一层或多层隐藏二维码图像。
在一些实施例中，获取二维码图像中的隐藏二维码图像包括：根据用户身份确定允许解析的隐藏二维码图像的层数；从二维码图像中逐层获取下一层的隐藏二维码图像，直至达到层数。
在一些实施例中，二维码图像隐藏的方法包括：基于离散小波变换的图像隐藏算法、基于混沌的图像隐藏算法、图像水印算法中的一种或多种。
通过这样的方法，以不同用户身份扫描相同的二维码图像能够解析出不同的隐藏二维码图像，进而得到与对应的隐藏二维码图像相关联的数据信息，从而将为不同给用户准备的数据信息集中至同一个二维码中，提高二维码的信息容量，也提高了二维码信息解析的自适应能力。

下面通过附图和实施例，对本公开的技术方案做进一步的详细描述。
本公开的二维码信息读取方法的一些实施例的流程图如图1所示。
在步骤101中，获取用户扫描的二维码图像信息和用户身份信息。在一些实施例中，用户身份信息可以是用户终端的等级信息，或者登陆用户终端的用户的等级信息，或者其他身份信息，如普通用户、高级用户、会员或者管理员等。
在步骤102中，根据用户身份信息获取二维码图像中的隐藏二维码图像。在一些实施例中，二维码图像隐藏的方法可以包括基于离散小波变换的图像隐藏算法、基于混沌的图像隐藏算法、图像水印算法中的一种或多种，可以根据预先的协议确定算法，进而获取隐藏二维码图像。
在一些实施例中，可以对用户身份信息进行核查，若用户身份满足要求，则解析隐藏二维码，否则不执行隐藏图像解析，直接获取与扫描到的二维码图像相关联的数据信息。
在步骤103中，获取与隐藏二维码图像相关联的数据信息。
通过这样的方法，以不同用户身份扫描相同的二维码图像能够解析出不同的隐藏二维码图像，进而得到与对应的隐藏二维码图像相关联的数据信息，从而将为不同给用户准备的数据信息集中至同一个二维码中，提高二维码的信息容量，也提高了二维码信息解析的自适应能力。
在一些实施例中，二维码图像中的隐藏二维码图像可能包括一层或多层，每一层二维码图像可以与不同的数据相关联，从而提高二维码的容量。
在一些实施例中，还可以解析出每层的二维码，将不同层的二维码图像的数据信息按照次序拼接，得到完整的数据。这样的方法能够增加二维码的数据容量，仅使用二维码图像进行数据传递，达到无网络状态下的数据解析，减少二维码数据查看对网络的依赖。在一些实施例中，二维码图像中可以包括层数信息，以便终端确定解析隐藏二维码的次数，防止数据解析不完整或过度解析的情况出现。
在一些实施例中，与不同层二维码图像的相关的数据是为不同类型的用户准备的，不同类型的用户能够得到对应的数据。本公开的二维码信息读取方法的另一些实施例的流程图如图2所示。
在步骤201中，获取用户扫描的二维码图像信息和用户身份信息。
在步骤202中，根据用户身份确定允许解析的隐藏二维码图像的层数。如图3所示，二维码图像包括了5个二维码，用户看到的是第5层二维码图像，图像中隐藏了4层图像。每一次解析隐藏二维码会将隐藏的下一层二维码变为表面的二维码，如在二维码图像信息的基础上解析1次，得到的图像中包括1～4层二维码图像，其读取结 果与读取第4层隐藏二维码的关联数据相同。
例如，若用户为未注册用户，则不能解析隐藏图像，只能读取表面的第5层二维码图像的关联数据；若用户为普通用户，能够解析隐藏的第4层隐藏二维码图像；若用户为高级用户，能够解析隐藏的第3层隐藏二维码图像；若用户为会员，能够解析隐藏的第2层隐藏二维码图像；若用户为管理员身份，则能够解析隐藏的第1层隐藏二维码图像。
在步骤203中，从二维码图像中逐层获取下一层的隐藏二维码图像，直至达到层数。如，用户为会员，则在二维码图像信息的基础上逐层解析，解析3层，得到第2层二维码图像。
在步骤204中，获取与得到的隐藏二维码图像相关联的数据信息。
通过这样的方法，能够自动识别用户类型，为不同类型的用户展示不同内容，一方面将多个二维码隐藏至一个二维码中，减少了展示面积，也避免了用户主动去选择要扫描的二维码，提高了用户友好度；另一方面，避免了用户查看为别的类型的用户准备的信息，提高了信息的安全性。
在一些实施例中，同一个类型的用户能够查看的信息可以与多个二维码相关联，分别解析出各个二维码图像的关联数据后将数据拼接，得到向用户展示的数据信息。通过这样的方法，能够解决单个二维码容量有限的问题，提高二维码的容量。在一些实施例中，二维码中可以包括图像中隐藏或融合的二维码个数信息，方便进行隐藏二维码的解析和数据拼接。
本公开的二维码生成方法的一些实施例的流程图如图4所示。
在步骤401中，确定用户类型数量，如包括游客、普通用户、高级用户、会员以及管理员5种。
在步骤402中，生成与用户类型数量相等数量的二维码，每个二维码与一种类型的用户允许查看的数据相关联。
在步骤403中，将生成的二维码逐层隐藏，直至生成单个二维码图像。在一些实施例中，二维码图像隐藏的方法可以包括基于离散小波变换的图像隐藏算法、基于混沌的图像隐藏算法、图像水印算法中的一种或多种。
通过这样的方法，能够为提供给不同用户的数据分别生成二维码，并将二维码集中至一个二维码中，以不同用户身份扫描相同的二维码图像能够解析出不同的隐藏二维码图像，进而得到与对应的隐藏二维码图像相关联的数据信息，从而提高二维码的 信息容量，也提高了二维码信息解析的自适应能力。
本公开的二维码生成方法的另一些实施例的流程图如图5所示。
在步骤501中，将第一二维码隐藏入第二二维码中，生成一层嵌套二维码，设定计数器i＝1。
在步骤502中，将i层嵌套二维码隐藏入第i+2二维码中，生成i+1层嵌套二维码，如在步骤501的基础上，将一层嵌套二维码隐藏入第三二维码中，生成二层嵌套二维码中。二层嵌套二维码中包括三个二维码。
在步骤503中，判断是否完成全部二维码的嵌套。若已完成，则执行步骤505；若未完成嵌套，则执行步骤504。
在步骤504中，设置i＝i+1，执行步骤502，继续进行下一层嵌套。
如图6所示，将第一二维码嵌套入第二二维码中，生成一层嵌套二维码，其展示的图像与第二二维码相同；将一层嵌套二维码嵌套入第三二维码中，生成二层嵌套二维码，其展示的图像与第三二维码相同，以此类推，直至生成图中所示的四层嵌套二维码，四层嵌套二维码中隐藏有第一至第五二维码图像，其展示的图像与第五二维码相同。
在步骤505中，展示嵌入全部二维码的i层嵌套二维码。
通过这样的方法，能够将二维码依次嵌套隐藏，最终以一个二维码的状态展示，以便在解析过程中逐次得到下一层二维码。
在一些实施例中，可以按照用户的私密等级由高到低的顺序隐藏二维码，以使与私密等级越高的用户允许查看的数据相关联的二维码隐藏的越深层。通过这样的方法，能够避免与高等级用户相关联的二维码被频繁解析，降低了隐藏二维码被泄露的可能性，提高了数据安全性。
在一些实施例中，可以先估计或确定每个用户类型中的用户数量，然后按照用户数量由少到多的顺序隐藏二维码。这样的方法能够减少隐藏二维码解析的次数，提高为多数用户展示关联数据的效率，也降低了系统的负担。
在一些实施例中，同一个类型的用户能够查看的信息可以与多个二维码相关联，在数据解析过程中分别解析出各个二维码图像的关联数据后将数据拼接，得到向用户展示的数据信息。通过这样的方法，能够解决单个二维码容量有限的问题，提高二维码的容量。在一些实施例中，可以在最终的二维码上提供融合的或隐藏的二维码个数的信息，从而方便扫描过程中的数据提取。

隐藏图像解析单元702能够根据用户身份信息获取二维码图像中的隐藏二维码图像。在一些实施例中，二维码图像隐藏的方法可以包括基于离散小波变换的图像隐藏算法、基于混沌的图像隐藏算法、图像水印算法中的一种或多种，可以根据预先的协议确定算法，还可以从二维码图像中读取采用的算法，进而获取隐藏二维码图像。在一些实施例中，可以对用户身份信息进行核查，若用户身份满足要求，则解析隐藏二维码，否则不执行隐藏图像解析，直接获取与扫描到的二维码图像相关联的数据信息。
数据获取单元703能够获取与隐藏二维码图像相关联的数据信息。
这样的二维码信息读取装置在以不同用户身份扫描相同的二维码图像时能够解析出不同的隐藏二维码图像，进而得到与对应的隐藏二维码图像相关联的数据信息，从而将为不同给用户准备的数据信息集中至同一个二维码中，提高二维码的信息容量，也提高了二维码信息解析的自适应能力。

这样的二维码生成装置能够为提供给不同用户的数据分别生成二维码，并将二维码集中至一个二维码中，提高了二维码的信息容量，也提高了二维码信息解析的自适应能力。
在一些实施例中，二维码合成单元803能够采用如图5所示的步骤实现二维码嵌套，能够将二维码依次嵌套隐藏，最终以一个二维码的状态展示，以便在解析过程中逐次得到下一层二维码。
在一些实施例中，二维码合成单元803可以按照用户的私密等级由高到低的顺序隐藏二维码，以使与私密等级越高的用户允许查看的数据相关联的二维码隐藏的越深层。这样的二维码生成装置能够避免与高等级用户相关联的二维码被频繁解析，降低了隐藏二维码被泄露的可能性，提高了数据安全性。
在一些实施例中，二维码合成单元803可以先估计或确定每个用户类型中的用户数量，然后按照用户数量由少到多的顺序隐藏二维码。这样的二维码生成装置能够减少隐藏二维码解析的次数，提高为多数用户展示关联数据的效率，也降低了系统的负担。
