识别出一维码中白条，生成第二私钥要素；
根据一维码中的黑条和白条排列顺序对第一私钥要素和第二私钥要素进行排列。
当条形码为一维码时，一维码由黑条和白条组成，识别出一维码中的黑条生成第一私钥要素，识别出一维码中的白条生成第二私钥要素，第一私钥要素与第二私钥要素不相同，私钥由第一私钥要素和第二私钥要素组成。在得到第一私钥要素和第二私钥要素之后，将第一私钥要素和第二私钥要素根据一维码中的黑条和白条排列顺序进行相对应的排列。例如，一维码依次为黑条、白条、黑条，黑条代表二进制的0，白条代表二进制的1，在识别一维码中的黑条生成0，在识别一维码中的白条生成1，在识别完成黑条和白条，再按照黑条和白条的排列顺序对0、1进行排列，最终得到一组数据为010。
在识别出所述一维码中黑条，生成第一私钥要素的步骤中，包括：
识别出所述一维码中各黑条的宽度，根据各黑条的宽度不同，生成相应数量的第一私钥要素。
在识别出所述一维码中白条，生成第二私钥要素的步骤中，包括：
识别出所述一维码中各白条的宽度，根据各白条的宽度不同，生成相应数量的第二私钥要素。
当条形码为一维码时，一维码由黑条和白条组成，识别出一维码中的黑条生成第一私钥要素，识别出一维码中的白条生成第二私钥要素，第一私钥要素与第二私钥要素不相同，私钥由第一私钥要素和第二私钥要素组成。在得到第一私钥要素和第二私钥要素之后，将第一私钥要素和第二私钥要素根据一维码中的黑条和白条排列顺序进行相对应的排列。
在完成排列第一私钥要素和第二私钥要素之后，识别一维码中各黑条的宽度，根据各黑条的宽度不同，各黑条所对应位置的第一私钥要素的生成数量不同。具体地，黑条宽度越大，第一私钥要素数量越多。
在完成排列第一私钥要素和第二私钥要素之后，识别一维码中各白条的宽度，根据各白条的宽度不同，各白条所对应位置的第二私钥要素的生成数量不同。具体地，白条宽度越大，第二私钥要素数量越多。例如，一维码依次为黑条、白条、黑条，其中第一条黑条的宽度为3L，第二条白条的宽度为L，第三条黑条的宽度为2L，黑条代表二进制的0，白条代表二进制的1，在识别一维码中的黑条生成0，在识别一维码中的白条生成1，在识别完成黑条和白条，再按照黑条和白条的排列顺序对0、1进行排列，得到一组数据为010，再根据黑条和白条的宽度，第一条黑条的宽度为3L生成二进制0的数量为3个，第二条白条的宽度为L生成二进制1的数量为1个，第三条黑条的宽度为2L生成二进制0的数量为2个，为此，最终得到一组数据为000100。
在本实施例中，在步骤S102之后，所述方法包括：
将私钥发送给预设的移动终端。
在智能音箱扫描条形码生成私钥之后，将生成的私钥复制一份发送给预设移动终端。
移动终端具有私钥，在移动终端中使用私钥可以读取用户数据的内容。
在一些实施例中，在移动终端中生成条形码供智能音箱进行扫描，同时，移动终端根据该条形码生成私钥。其中，移动终端具有与智能音箱相同的私钥生成规则，为此，对于同一个条形码，在移动终端中生成的私钥与在智能音箱中生成的私钥是相同的。
步骤S103、使用所述私钥对用户数据进行加密。
在获得私钥之后，使用私钥对用户数据进行加密，加密后的用户数据需要私钥才能打开用户数据的内容。
私钥对用户数据的加密方式是将用户数据进行封装，对其进行加密，在没有获取私钥时，打开用户数据后是提供要求输入密码，或者，打开用户数据后是乱码，不能正常阅读。
步骤S104、将加密后的用户数据发送至云端。
将加密后的用户数据发送至云端，在云端中的用户数据，由于是已被加密，所以需要私钥才能打开。
综上所述，通过扫描条形码生成私钥，之后使用私钥对用户数据进行加密，最后才将用户数据发送至云端，本方法可随时更换私钥，且随机性高，不易破解，旨在解决现有的智能音箱的用户数据大多数都是没有进行任何的加密发送到云端，导致容易被别人读取使用者的用户数据的问题。
