密码检测方法、装置及终端 技术领域
本申请涉及通信技术领域，尤其涉及密码检测方法、装置及终端。
背景技术
随着通信技术的发展，终端(例如智能手机、平板电脑、可穿戴设备等)可以支持多用户访问，为了用户的隐私安全，可以为不同用户设置不同的密码，同时为不同用户设置不同的访问空间，进而，终端可以通过密码来区分用户身份，并允许用户访问与该用户身份匹配的空间，例如，终端可以将主用户密码设置为1234，将子用户密码设置为5678，并允许主用户访问主用户空间，主用户空间可以包括通讯录、相册中的数据等，允许子用户访问子用户空间，子用户空间可以包括音乐应用中的数据等。
通常，终端在接收到用户输入的密码时，可以无需用户输入确认指令而直接进入终端系统，以提高用户体验。但是，在主用户密码与子用户密码的前几位存在重叠时，或者在子用户密码与主用户密码的前几位存在重叠时，会导致主用户密码或者子用户密码无法使用，例如，若终端将主用户密码设置为1234，子用户密码设置为123456，则子用户输入1234时，终端将直接进入主用户空间；若终端将主用户密码设置为123456，子用户密码设置为1234，则主用户输入1234时，终端将直接进入子用户空间。

本申请中，终端可以获取主用户密码的修改请求，该修改请求可以携带用户输入的第一主用户密码，该第一主用户密码用于对主用户的身份验证，以提高修改密码的安全性。
作为一种可选的实施例，终端在执行步骤S101之前还可以执行以下步骤：终端可以获取主用户密码的注册请求，该注册请求携带输入的第二主用户密码，并获取该第二主用户密码的第二不可逆参考值。
本申请中，通常终端会首先对主用户密码注册，然后对子用户密码注册，因此，终端在对主用户密码注册时，可以不对主用户密码进行合规性检测。终端可以获取主用户密码的注册请求，该注册请求携带输入用户的第二主用户密码，并使用不可逆加密算法对该第二主用户密码进行加密，以获取该第二主用户密码的第二不可逆参考值，并可以将该第二不可逆参考值存储在终端中，由于终端中存储的不是该第二密码的明文，因此可以提高主用户密码的安全性。
需要说明的是，该不可逆加密算法可以包括基于密码的密钥派生函数(Password-Based Key Derivation Function 2，PBKDF2)、基于哈希运算的消息认证码(Hash-based Message  Authentication Code，HMAC)或消息摘要算法(Message Digest Algorithm 5，MD5)等加密算法，上述加密算法仅是举例，而非穷举，包含但不限于上述加密算法。为了增加各个不可逆参考值的可比性，本发明中，均使用同一种不可逆加密算法对各个主用户密码及子用户密码进行加密。另外，子用户密码或者主用户密码的不可逆参考值可以包括数值、中文文字、字母或符号中的一种或多种。
需要进一步说明的是，若终端存储子用户密码的明文或主用户密码的明文，则容易导致主用户密码或子用户密码泄漏，因此本发明中，终端存储的是子用户密码的不可逆参考值或主用户密码的不可逆参考值，可以提高用户密码的安全性。
S102、获取该第一主用户密码的第一不可逆参考值，以及该主用户当前的第二主用户密码的第二不可逆参考值。
本申请中，终端可以使用不可逆加密算法对第一主用户密码进行加密，以获取该第一主用户密码的第一不可逆参考值，以及可以从该终端中获取该主用户当前的第二主用户密码的第二不可逆参考值。
S103、判断该第一不可逆参考值与该第二不可逆参考值是否一致，若一致，则可以执行步骤S104，否则，结束本次流程。
本申请中，终端可以将该第一不可逆参考值与该第二不可逆参考值进行比较，以判断该第一不可逆参考值与该第二不可逆参考值是否一致，以对该主用户进行身份验证，并可以提高修改密码的安全性。当该第一不可逆参考值与该第二不可逆参考值一致时，终端可以执行步骤S104，否则，结束本次流程，同时，终端也可以输出提示信息，以提示输入密码错误。
需要说明的是，步骤S101～S103是使用接收用户输入密码的方式对主用户进行身份验证，终端还可以接收用户输入指纹的方式对主用户进行身份验证，也可以使用其他方式对该主用户进行身份验证，本发明对此不做限定。
S104、接收输入的第三主用户密码。
本申请中，当该第一不可逆参考值与该第二不可逆参考值一致时，终端可以接收输入的第三主用户密码，以便可以对该第三主用户密码进行第一合规性检测。
S105、根据子用户密码的第三不可逆参考值，对该第三主用户密码进行第一合规性检测，该第一合规性检测用于检测该第三主用户密码是否满足该主用户密码的设定条件，若满足，则终端可以执行步骤S106，否则，执行步骤S107。
举例来说，若子用户密码为12345，该第三主用户密码为1234，由于该第三主用户密码与该子用户密码的前四位重叠，因此终端可以根据子用户密码的第三不可逆参考值，确定该第三主用户密码不满足该第一合规性；若子用户密码为12345，该第三主用户密码为123456，由于该子用户密码与该第三主用户密码的前五位重叠，因此终端可以根据子用户密码的第三不可逆参考值，确定该第三主用户密码不满足第一合规性；若子用户密码为12345，该第三主用户密码为45614，由于该子用户密码与第三主用户密码不重叠，因此终端可以根据子用户密码的第三不可逆参考值，确定该第三主用户密码满足第一合规性。
本申请中，终端可以根据该第三不可逆参考值，对该第三主用户密码进行第一合规性检测，可以防止该第三主用户密码与子用户密码冲突，即可以防止该第三主用户密码与该 子用户密码的前几位重叠或者防止子用户密码与该第三主用户密码的前几位重叠。
需要说明的是，终端在对该第三主用户密码进行第一合规性检测之前，可以检测是否已经注册子用户密码，若已经注册，则终端可以执行步骤S105对第三主用户密码进行第一合规性检测；否则，终端可以结束本次流程。
S106、将该第三主用户密码作为更新后的主用户密码。
本申请中，若该第三主用户密码满足该第一合规性，即在该第三主用户密码与子用户密码不冲突时，终端可以将该第三主用户密码作为更新后的主用户密码。
具体的，若该第三主用户密码满足该第一合规性，则终端可以将该第三主用户密码作为第二主用户密码，将第三主用户密码的不可逆参考值作为该第二主用户密码的不可逆参考值，并存储该第二主用户密码的不可逆参考值及该第二主用户密码的长度。
S107、输出第一提示信息，该第一提示信息用于提示所述第三主用户密码不满足该第一合规性。
本申请中，若所述第三主用户密码不满足该第一合规性，即在该第三主用户密码与子用户密码冲突时，终端可以输出第一提示信息，该第一提示信息用于提示该第三主用户密码不满足该第一合规性，以便用户可以根据提示信息做出相应的操作，如重新输入第三主用户密码。
需要说明的是，输出的第一提示信息可以是以文字的方式传输的，还可以是以语音的方式输出的，还可以是两者结合的方式输出的，本发明对此不做限定。
需要说明的是，如果子用户密码或主用户密码的长度太短，子用户密码和主用户密码容易被破解，即用户密码的安全性较低；如果子用户密码或主用户密码的长度太长，需要较长时间来进行冲突检测，从而导致用户密码的可用性较低，因此可以综合考虑用户密码的安全性及可用性来限制子用户密码或主用户密码的长度。
需要说明的是，终端可以在子用户密码注册之前，对主用户密码进行修改；也可以在子用户密码注册之后，对主用户密码进行修改，若终端在子用户密码注册之前，对主用户密码进行修改，则不需要对主用户密码进行合规性检测；若终端在子用户密码注册之后，对主用户密码进行修改，则需要对主用户密码进行合规性检测。
本申请中，终端在修改主用户密码时，终端通过将输入的第一主用户密码的第一不可逆参考值与该主用户当前的第二主用户密码(即旧主用户密码)的第二不可逆参考值进行比较，以对主用户进行身份验证，可以提高修改密码的安全性，当该第一不可逆参考值与该第二不可逆参考值一致时，接收输入的第三主用户密码，并对第三主用户密码(即新主用户密码)进行第一合规性检测，以防止该第三主用户密码与子用户密码冲突，可以提高用户密码的安全性。
基于上述密码检测方法的实施例的描述，本申请实施例提供的再一种密码检测方法的流程示意图。请参见图2，如图2所示的密码检测方法，可以包括以下几个步骤：
S201、根据主用户当前的第二主用户密码派生得到第二派生密钥。
S202、使用该第二派生密钥对预设私钥进行加密，得到该预设私钥的密文。
举例来说，终端可以使用PBKDF2算法对第二主用户密码派生出第一派生密钥(即 AES-KEY)，并使用AES-KEY对该预设私钥进行加密，以得到该预设私钥的密文。或使用PBKDF2算法对第二主用户密码派生出固定值，并基于该固定值派生出第一派生密钥(即ECIES公私钥对)，使用ECIES公私钥对，对该预设私钥进行加密，以得到该预设私钥的密文。上述对该预设私钥进行加密的方式仅是举例，而非穷举，包含但不限于上述加密方式。
本申请中，终端可以执行步骤S201及S202，基于该第二主用户密码派生得到第二派生密钥对该预设私钥进行加密，得到该预设私钥的密文，可以提高该预设私钥的安全性。
S203、使用预设公钥分别对各个第四不可逆参考值进行加密，得到各个该第四不可逆参考值的密文。
本申请中，终端可以使用预设公钥分别对各个该第四不可逆参考值进行加密，得到各个该第四不可逆参考值的密文，可以提高该第四不可逆参考值的安全性。
需要说明的是，上述预设公钥和预设私钥可以是公私钥对，该公私钥对可以是安全性较高的非对称加密算法的公私钥对，如非对称加密算法(Rivest Shamir Adleman-2048，RSA-2048)或ECIES-256的公私钥对。上述的公私钥对仅是举例，而非穷举，包含但不限于上述公私钥对。
需要说明的是，该第四不可逆参考值为该子用户密码所包含的多个子用户子密码的不可逆参考值，该子用户子密码为该子用户密码的一个密码段，如该子用户子密码为1456，则该子用户密码所包含的多个子用户子密码为145、14、1，该第四不可逆参考值为该多个子用户子密码的不可逆参考值。
需要说明的是，终端可以在主用户密码注册时执行步骤S201及S202，在子用户密码注册时，执行步骤S203。
S204、获取主用户密码的修改请求，该修改请求携带输入的第一主用户密码。
S205、获取该第一主用户密码的第一不可逆参考值，以及该主用户当前的第二主用户密码的第二不可逆参考值。

S207、获取该子用户密码的长度及该第三主用户密码的长度。
S208、当该子用户密码的长度大于该第三主用户密码的长度时，根据该第一主用户密码派生得到第一派生密钥。
S209、使用该第一派生密钥对该预设私钥的密文进行解密，得到该预设私钥。
举例来说，终端可以使用PBKDF2算法对第一主用户密码派生出第一派生密钥(即AES-KEY)，并使用高级加密标准密钥(Advanced Encryption Standard-KEY，AES-KEY)对该预设私钥的密文进行解密，以得到该预设私钥。或使用PBKDF2算法对第一主用户密码派生出固定值，并基于该固定值派生出第一派生密钥(即ECIES公私钥对)，使用椭圆曲线集成加密策略(Elliptic Curve Integrated Encryption Scheme，ECIES)公私钥对，对该预设私钥的密文进行解密，得到该预设私钥。上述对该预设私钥的密文进行解密的方式仅是举例，而非穷举，包含但不限于上述解密方式，同时在实际操作中，由于解密过程是加密过程的逆过程，因此解密方式主要由加密方式确定。
本申请中，终端可以执行步骤S208及S209，根据该第一主用户密码派生得到第一派生密钥，使用该第一派生密钥对该预设私钥的密文进行解密，得到该预设私钥，以便可以使用该预设私钥对第四不可逆参考值的密文进行解密。
S210、使用预设私钥对各个第四不可逆参考值的密文进行解密，得到各个该第四不可逆参考值。
本申请中，当该子用户密码的长度大于该第三主用户密码的长度时，终端可以将子用户子密码的第四不可逆参考值与第三主用户的第五不可逆参考值进行比较，以判断该第三主用户密码是否与该子用户密码冲突，另外，终端将子用户子密码的第四不可逆参考值进行加密存储，可提高子用户密码的穷举安全性。因此，当该子用户密码的长度大于该第三主用户密码的长度时，终端可以使用预设私钥对各个第四不可逆参考值的密文进行解密，得到各个该第四不可逆参考值。
S211、将该第三主用户密码的第五不可逆参考值与第一子用户子密码的第四不可逆参考值进行比较，以判断该第三主用户密码是否满足该第一合规性，若满足，则终端可以执行步骤S212；否则，执行步骤S213。
本申请中，终端可以使用该第一子用户子密码的第四不可逆参考值与该第五不可逆参考值进行比较，不仅可以判断该第三主用户密码是否满足该第一合规性，即可以判断该第三主用户密码是否与该子用户密码冲突，还可以避免将所有的第四不可逆参考值与该第五不可逆参考值进行比较带来较大的系统内存消耗，进而可以提高冲突检测的效率。具体的，当该第三主用户密码的第五不可逆参考值与第一子用户子密码的第四不可逆参考值不相同时，可以确定该第三主用户密码满足该第一合规性；当该第三主用户密码的第五不可逆参考值与第一子用户子密码的第四不可逆参考值相同时，可以确定该第三主用户密码不满足该第一合规性。
需要说明的是，该第一子用户子密码的长度与该第三主用户密码的长度相同，如，第三主用户密码为123564，该子用户密码为14568456，则该第一子用户子密码可以为145684。
举例来说，假如第三主用户密码为123564，终端获取到的该子用户密码的长度为8，及该第三主用户密码的长度为6。终端可以使用不可逆加密算法对该第三主用户密码进行加密，以得到该第三主用户密码的第五不可逆参考值。终端可以将可以使用预设私钥对各个第四不可逆参考值的密文进行解密，得到各个该第四不可逆参考值，该第四不可逆参考值为该子用户密码所包含的多个子用户子密码的不可逆参考值。终端可以将该第一子用户子密码的第四不可逆参考值与该第五不可逆参考值进行比较，若该子用户子密码为14568456，则终端可以确定该第五不可逆参考值与第一子用户子密码(该第一子用户子密码为145684)的第四不可逆参考值不相同，并可以确定该第三主用户密码满足该第一合规性；若该子用户子密码为12356445，则终端可以确定该第五不可逆参考值与第一子用户子密码(该第一子用户子密码为123564)的第四不可逆参考值相同，并可以确定该第三主用户密码不满足该第一合规性。
S212、将该第三主用户密码作为更新后的主用户密码。

本申请中，在对主用户密码进行修改时，如果该子用户密码的长度大于该第三主用户密码(新主用户密码)的长度，终端可以将该第三主用户密码的第五不可逆参考值与第一子用户子密码的第四不可逆参考值进行比较，以判断该第三主用户密码是否满足该第一合规性，可以防止第三主用户密码与子用户密码冲突，并可以提高用户密码的安全性，另外，终端将子用户子密码的第四不可逆参考值进行加密存储，提高了子用户密码的穷举安全性。

S501、获取子用户密码的注册请求，该注册请求携带输入的该子用户密码。
需要说明的是，通常终端仅允许主用户对子用户密码进行注册，即在接收到子用户密码的注册请求时，终端可以使用密码或指纹的方式对主用户进行身份验证，在身份验证成功时，可以执行步骤S502；若验证失败，可以结束本次流程，并可以输出提示信息，以提示输入密码或者指纹信息错误。
S502、根据该当前主用户的第二主用户密码第二不可逆参考值，对该子用户密码进行第二合规性检测，该第二合规性检测用于检测该子用户密码是否满足该子用户密码的设定条件，若满足，则终端可执行步骤S503，否则，终端可以执行步骤S504。
举例来说，子用户密码为1234，第二主用户密码为12345，由于该子用户密码与该第二主密码的前四位重叠，因此终端可以根据该第二主用户密码的第二不可逆参考值，确定该子用户密码不满足第二合规性；若子用户密码为12345，该第二主用户密码为1234，由于该第二主用户密码与该子用户密码的前四位重叠，因此终端可以根据该第二主用户密码的第二不可逆参考值，确定该子用户密码不满足第二合规性；若子用户密码为12345，该第二主用户密码为1554，由于该第二主用户密码与该子用户密码不重叠，因此终端可以根据该第二主用户密码的第二不可逆参考值，确定该子用户密码满足第二合规性。

本申请中，当该子用户密码的长度小于该第二主用户密码的长度时，终端可以将各个子用户补齐密码的第七不可逆参考值与该第二不可逆参考值进行比较，当任一第七不可逆参考值与该第二不可逆参考值不相同时，可以确定该子用户密码满足该第二合规性，终端可以执行步骤S605；当存在第七不可逆参考值与该第二不可逆参考值相同时，终端可以确定该子用户密码不满足该第二合规性，可以执行步骤S606。
S605、完成该子用户密码的注册。
S606、输出第二提示信息，该第二提示信息用于提示该子用户密码不满足该第二合规性。
