Description

一种学生信息存储方法、可读存储介质、终端设备及装置
本申请要求于2018年2月7日提交中国专利局、申请号为CN201810121674.5、发明名称为“一种学生信息存储方法、计算机可读存储介质及终端设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请属于区块链技术领域,尤其涉及一种学生信息存储方法、计算机可读存储介质、终端设备及装置。
背景技术
目前通常使用的学生信息存储方式可以分为两类,一类是集中式存储,这种方式会将所有的学生信息集中存储在一个服务器中,但是这种存储方式在被黑客侵入或者发生故障时极易发生学生信息被篡改或者损坏的情况,安全性较低;另一类是分布式存储,这种方式会将学生信息分布存储在多个服务器中,也即形成了多套备份,有效地提高了信息的安全性,但是由于这种方式是以冗余度来换取安全性,在学生信息较多的情况下,会浪费大量的存储资源。
技术问题
有鉴于此,本申请实施例提供了一种学生信息存储方法、计算机可读存储介质、终端设备及装置,以解决现有的集中式存储安全性较低,以及分布式存储浪费大量的存储资源的问题。
技术解决方案
本申请实施例的第一方面提供了一种学生信息存储方法,所述方法应用于预设的学生信息存储区块链中的任意一个节点,所述学生信息存储区块链包括两条以上的子区块链,所述学生信息存储区块链中的任意一个节点属于一条以上的所述子区块链,所述方法包括:
接收目标终端发送的学生信息,所述学生信息由与所述目标终端对应的预设的第一私钥签名;
使用预设的第一公钥对所述学生信息进行解签,得到解签后的学生信息,所述第一公钥和所述第一私钥属于同一密钥对;
确定所述解签后的学生信息的数据类型;
根据预设的数据类型对应关系从所述学生信息存储区块链中选取与所述数据类型对应的子区块链,所述数据类型对应关系用于指示所述数据类型与所述子区块链之间的对应关系;
若所述学生信息存储区块链中存在与所述数据类型对应的子区块链,则将与所述数据类型对应的子区块链确定为目标子区块链;
根据所述解签后的学生信息生成用于在所述目标子区块链中存储的目标区块;
在所述目标子区块链中广播所述目标区块,以使所述目标子区块链中的各个节点根据所述目标区块更新本地存储的学生信息。
本申请实施例的第二方面提供了一种计算机可读存储介质,所述计算机可读存储介质存储有计算机可读指令,所述计算机可读指令被处理器执行时实现上述学生信息存储方法的步骤。
本申请实施例的第三方面提供了一种学生信息存储终端设备,所述终端设备包括存储器、处理器以及存储在所述存储器中并可在所述处理器上运行的计算机可读指令,所述处理器执行所述计算机可读指令时实现上述学生信息存储方法的步骤。
本申请实施例的第四方面提供了一种学生信息存储装置,可以包括用于实现上述学生信息存储方法的步骤的模块。
有益效果
本申请实施例与现有技术相比存在的有益效果是:通过本申请实施例,一方面,每个子区块链中的节点存储相同的学生信息,即各种数据类型的学生信息也都存在多个备份,整体的安全性较高,另一方面,将不同数据类型的学生信息分别存储在不同的子区块链中,大大降低了整体的冗余度,减少了对于存储资源的消耗。

图4为本申请实施例中一种学生信息存储终端设备的示意框图。
本发明的实施方式
本申请实施例中的学生信息存储方法应用于预设的学生信息存储区块链中的任意一个节点,所述学生信息存储区块链包括两条以上的子区块链,所述学生信息存储区块链中的任意一个节点属于一条以上的所述子区块链。
这些节点可以是学校、校外教育机构、教育监管机构等机构用于存储学生信息的服务器。例如,学校部署的节点分别为节点11、节点12和节点13,这三个节点分别配置有子区块链A、子区块链B和子区块链C;校外教育机构X部署的节点分别为节点21和节点22,这两个节点分别配置有子区块链A和子区块链B;校外教育机构Y部署的节点分别为节点31和节点32,这两个节点分别配置有子区块链A和子区块链C;教育监管机构部署的节点分别为节点41、节点42和节点43,这三个节点分别配置有子区块链A、子区块链B和子区块链C。
请参阅图1,本申请实施例中一种学生信息存储方法的一个实施例可以包括:
步骤S101、接收目标终端发送的学生信息。
所述学生信息是指由当前节点所服务的学生通过其终端发送的数据,例如,该学生信息可以是某学生发起的培训申请。
为了进一步提高学生信息存储过程的安全性,避免接收到恶意人员伪装发来的学生信息,所述学生信息可以由与所述目标终端对应的预设的第一私钥进行签名。
步骤S102、使用预设的第一公钥对所述学生信息进行解签,得到解签后的学生信息。
所述第一公钥和所述第一私钥属于同一密钥对。所述密钥对是在该学生在当前节点注册时由当前节点生成的,在密钥对生成后,当前节点保存其中的第一公钥,并将第一私钥发送给学生使用的所述目标终端进行保存。
步骤S103、确定所述解签后的学生信息的数据类型。
例如,数据类型a1可以为学生个人基本数据(姓名、性别、生日、籍贯等等),数据类型a2可以为学生成绩数据,数据类型b可以为在校外教育机构X的培训记录,数据类型c可以为在校外教育机构Y的培训记录等等。
步骤S104、根据预设的数据类型对应关系从所述学生信息存储区块链中选取与所述数据类型对应的子区块链。
所述数据类型对应关系用于指示所述数据类型与所述子区块链之间的对应关系。
考虑到合作的多家机构之间对不同数据类型的学生信息的共享需求不同,例如,四家机构合作,其中两家机构需要共享数据类型a2的学生信息,该四家机构需要共享数据类型a1的学生信息,因此为了更好地隔离不同数据类型的学生信息的存储权限,可以按照学生信息的数据类型,将不同数据类型的学生信息存储到不同的子区块链上。
步骤S105、判断所述学生信息存储区块链中是否存在与所述数据类型对应的子区块链。
若所述学生信息存储区块链中存在与所述数据类型对应的子区块链,则执行步骤S106, 若所述学生信息存储区块链中不存在与所述数据类型对应的子区块链,则执行步骤S107。
步骤S106、将与所述数据类型对应的子区块链确定为目标子区块链;
步骤S107、将所述学生信息存储区块链中预设的默认子区块链确定为所述目标子区块链;
为了便于多个机构之间不受数据类型的限制来共享数据,还可以配置一条共享的默认子区块链,该默认子区块链用于存储多个机构之间共享的学生信息,例如,对于具有普遍共享需求的学生个人基本数据或学生成绩数据等学生信息,均可以存储到默认子区块链中。
步骤S108、根据所述解签后的学生信息生成用于在所述目标子区块链中存储的目标区块。
具体地,获取本地存储的所述目标子区块链的链尾区块,所述链尾区块为最新添加入所述目标子区块链中的区块,所述目标子区块链的每个区块均包括区块头和区块主体;对所述链尾区块的区块头进行特征运算,得到第一特征值;对所述解签后的学生信息进行特征运算,得到第二特征值;根据所述第一特征值和所述第二特征值生成所述目标区块的区块头,并根据所述解签后的学生信息生成所述目标区块的区块主体。
步骤S109、在所述目标子区块链中广播所述目标区块,以使所述目标子区块链中的各个节点根据所述目标区块更新本地存储的学生信息。
需要注意的是,步骤S108和步骤S109采取的是由当前节点来进行目标区块生成以及广播的工作。在本实施例的另一种实现中,也可以由其它节点来进行目标区块生成以及广播的工作,具体地,当前节点可以从所述目标子区块链选取一个节点作为目标节点;将所述解签后的学生信息发送至所述目标节点,以使所述目标节点根据所述解签后的学生信息生成所述目标区块,并在所述目标子区块链中广播所述目标区块。
优选地,在所述目标子区块链中广播所述目标区块之后,所述学生信息存储方法还可以包括如图2所示的对广播的所述目标区块进行核对的过程:
步骤S201、接收所述目标子区块链中的各个节点反馈的对所述目标区块进行核对后的核对结果。
所述目标子区块链中的各个节点在接收到广播的所述目标区块后,各自独立地对其进行校验,即各自在本地重新进行一次目标区块的生成过程,并将本地生成的结果与所述目标区块进行对比,若两者一致,则向当前节点反馈正确的核对结果,若两者不一致,则向当前节点反馈错误的核对结果。
步骤S202、统计所述核对结果为正确的个数以及所述核对结果为错误的个数。
步骤S203、判断所述目标子区块链预设的节点总个数、所述核对结果为正确的个数以及所述核对结果为错误的个数是否满足预设的判定条件。
在本实施例中,将所述目标子区块链预设的节点总个数用Total_Num表示,将所述核对结果为正确的个数用Pos_Num表示,将所述核对结果为错误的个数用Neg_Num表示,则所述判定条件可表示为:
(Pos_Num+Neg_Num)/Total_Num>Threshold1
且Pos_Num/Neg_Num>Threshold2
其中,Threshold1和Threshold2均为预设的阈值。
若满足所述判定条件,则执行步骤S204,若不满足所述判定条件,则执行步骤S205。
步骤S204、向所述核对结果为错误的节点下发存储所述目标区块的指令。
