附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的一种信息处理系统的结构示意图；
图2为本发明实施例提供的一种基于区块链的数据管理方法的流程示意图；
图3为本发明实施例提供的另一种基于区块链的数据管理方法的流程示意图；
图4是本发明实施例提供的一种基于区块链的数据管理装置的示意性框图；
图5是本发明实施例提供的一种区块链系统的结构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
区块链技术是一种互联网数据库技术，其本质是去中心化且寓于分布式结构的数据存储、传输和证明的方法。区块链系统正是基于区块链技术，用数据区块取代了目前互联网对中心服务器的依赖，使得所有数据变更或交易项目都记录在一个云系统之上，实现了数据传输中对数据的自我证明。一旦信息经过验证并添加至区块链系统，就会永久的存储起来，并且登记在区块链系统上的数据具备不可篡改性。在区块链系统上部署的智能合约是一份可以在中央处理器(Central Processing Unit，CPU)执行合约代码的数字合同，当满足智能合约的条款内容时，可以自动化的执行预先定义好的规则和条款。
目前，传统的数据系统一般为中心化系统，这种系统在数据发生改变时，对于客户或者消费者来说是不知情的，那么这类数据系统就很容易出现数据篡 改的情况，使得数据的真实性无法得到保证。基于这种需求，区块链技术应运而生，但对于已存在传统数据系统或者需要具有中心化管理的企业而言，如果仅仅应用区块链技术，不能满足企业的实际需求。其中，中心化系统可以是银行系统、贷款系统、证券或保险等金融系统，也可以是任一公司的总部系统等等。
为了解决上述问题，请参见图1，本发明实施例提供了一种信息处理系统，该信息处理系统包括中心化系统和区块链系统，可以应用于贷款、证券、保险、金融等领域，其中，区块链系统为一个分布式管理系统，该分布式管理系统包括至少一个节点。本发明实施例中，可以一个节点对应一个节点设备，也可以多个节点对应一个节点设备。其中，该节点设备可以为一种终端设备，终端设备可包括但不限于：PC(Personal Computer，个人计算机)、PAD(平板电脑)、手机、智能手机、笔记本电脑等设备；还可以为一种服务器。
在一个实施例中，中心化系统可以将所变更的数据(即第一变更数据)发送至区块链系统。进一步地，区块链系统接收到来自中心化系统的第一变更数据后，可以检测是否存在与第一变更数据相关联的账户信息，如果存在，则向账户信息对应的目标账户发出提示信息，用于提示目标账户对应的数据已被变更。本发明实施例建立这种区块链系统与中心化系统结合的信息处理系统，一方面可以在不需要对传统数据系统做较大调整的情况下，实现数据基于区块链的分布式管理；另一方面还保留了传统数据系统的中心化管理特权，从而更加满足行业实际需求；又一方面还可以在数据发生变更时通知所变更数据对应的目标账户，使得数据变更的消息及时有效的传达。
需要说明的是，本发明所描述的第一变更数据和第二变更数据可以指代任何数据，两者可以相同或者不同。针对不同的应用场景，第一变更数据和第二变更数据可以指代不同的数据。例如，当应用场景为贷款系统时，第一变更数据可以为某企业的销售数据，第二变更数据可以为某企业的贷款金额等等；又例如，当应用场景为保险系统时，第一变更数据可以为张三在某年投保的数额，第二变更数据可以张三在某年的出险次数等等。本发明对此不作具体限定。
本发明所描述的与上述第一变更数据相关联的账户信息，可以包括以下至少一种：第一变更数据的数据类型对应的账户信息和第一变更数据中包括的账 户信息。该账户信息可以是预先设置的，例如可以为企业账户、用户ID等等。本发明所描述的目标账户为区块链系统上与上述账号信息对应的区块链账户(以下简称区块链目标账户)。
本发明所描述的对数据进行变更，其中，所述变更包括对数据进行增加、修改和删除中的至少一种，本发明对此不作具体限定。
再参见图2，图2是本发明实施例提供的一种基于区块链的数据管理方法的流程示意图，该方法应用于信息处理系统，该信息处理系统包括中心化系统和区块链系统，如图所示，该数据管理方法可包括：
S201：区块链系统接收中心化系统发送的第一变更数据，并将第一变更数据更新至区块链系统中包括的各个节点。
在一个实施例中，当中心化系统检测到数据变更时，可以通过已建立连接的上述第一节点将变更的数据(即第一变更数据)发送至区块链系统。进一步地，区块链系统接收到第一变更数据后，可以将该第一变更数据更新至区块链系统中的各个节点，从而实现数据的分布式管理。
在一个实施例中，区块链系统接收到第一变更数据后，可以将第一变更数据发送至区块链系统中的各节点，并在各节点各自对应的存储装置中查找到第一变更数据对应的目标数据，并将目标数据变更为第一变更数据，从而达到将第一变更数据更新至区块链系统中的各个节点的目的，实现数据的分布式管理。其中，第一变更数据和目标数据两者是相关关联或者相互对应的，例如，第一变更数据为3月份企业A的还款金额，那么目标数据也为3月份企业A的还款金额。
示例性地，中心化系统发送的第一变更数据为张三2018年的车险缴纳金额，具体金额为3500，区块链系统接收到中心化系统发送的该第一变更数据后，则可以将第一变更数据发送到区块链系统的各个节点，并在各节点各自对应的存储装置中查找到张三2018年的车险缴纳金额对应的这部分数据，并将张三2018年的车险缴纳金额变更为3500。
S202：区块链系统检测是否存在与第一变更数据相关联的账户信息。其中，该与第一变更数据相关联的账户信息，可以包括以下至少一种：第一变更数据 的数据类型对应的账户信息和第一变更数据中包括的账户信息。该账户信息可以是预先设置的，例如可以为企业账户、用户ID等等。
在一个实施例中，区块链系统可以针对不同类型的数据预先绑定各自对应的账户信息，如表1-1所示。这种情况下，区块链系统可以在接收到来自中心化系统的第一变更数据后，确定第一变更数据的数据类型，进而检测数据类型是否绑定有账户信息，若第一变更数据的数据类型绑定有账户信息，即可认为检测到存在与第一变更数据相关联的账户信息；与之对应地，若第一变更数据的数据类型未绑定有账户信息，即可认为检测到不存在与第一变更数据相关联的账户信息。示例性的，数据类型与账户信息的绑定关系可以如表1-1所示，如果区块链系统确定出第一变更数据的数据类型为Type-1，那么则可以根据预先设置的该绑定关系检测到Type-1绑定的账户信息为M-01，也即可确定第一变更数据的数据类型存在绑定的账户信息。或者，如果区块链系统确定出第一变更数据的数据类型为Type-3，则根据预先设置的该绑定关系无法检测到与Type-3绑定的账户信息，也即可确定第一变更数据的数据类型不存在绑定的账户信息。
表1-1
数据类型 账户信息
Type-1 M-01
Type-2 M-02
在一个实施例中，区块链系统可以在接收到来自中心化系统的第一变更数据后，确定第一变更数据中是否存在有账户信息。进一步地，如果区块链系统在第一变更数据中识别到账户信息，则可以确定存在与第一变更数据相关联的账户信息；如果区块链系统在第一变更数据中未识别到账户信息，则可以确定不存在与第一变更数据相关联的账户信息。
S203：若区块链系统检测到存在与第一变更数据相关联的账户信息，则向账户信息对应的目标账户发出提示信息。该提示信息用于提示目标账户对应的数据已被变更。
在一个实施例中，区块链系统如果检测到存在与第一变更数据相关联的账户信息，则可以从账户信息中识别出目标账户，并向该目标账户发出提示信息，用于提示目标账户对应的数据已被变更，可以在数据发生变更时，通知所变更数据对应的目标账户，不仅有利于保证数据安全性，还有利于保证数据的真实性。在一个实施例中，该提示信息除了可以提示目标账号对应的数据已被更改以外，还可以提示目标账号第一变更数据对应的数据已被更改。例如，第一变更数据为企业A的销售金额，其具体金额为1万元，那么该提示信息则可以为“企业A的销售金额已被变更为1万元”。
在一个实施例中，区块链系统还可以获取目标账户相关联的联系方式，进而通过该联系方式向目标账户发出提示信息。其中，该联系方式例如可以为短信、邮件、聊天工具消息等。示例性地，若第一变更数据为4月份企业A的销售数据，区块链系统从与该第一变更数据关联的账号信息中识别出的目标账户包括：number-01和number-02。这种情况下，区块链系统可以向目标账户number-01和number-02发出提示信息，用于提示目标账户4月份企业A的销售数据已被变更。
本发明实施例中，区块链系统可以接收中心化系统发送的第一变更数据，将第一变更数据更新至区块链系统中包括的各个节点，并检测是否存在与第一变更数据相关联的账户信息，如果检测到存在与第一变更数据相关联的账户信息，则向账户信息对应的目标账户发出提示信息。采用本发明，一方面可以在不需要对传统数据系统做较大调整的情况下，实现数据基于区块链的分布式管理；另一方面还可以在数据发生变更时通知所变更数据对应的区块链目标账户，使得数据变更的消息及时有效的传达。
再参见图3，图3是本发明实施例提供的一种基于区块链的数据管理方法的流程示意图，该方法应用于信息处理系统，该信息处理系统包括中心化系统和区块链，如图所示，该数据管理方法可包括：
S301：区块链系统接收中心化系统发送的第一变更数据，并将第一变更数据更新至区块链系统中包括的各个节点。
S302：区块链系统检测是否存在与第一变更数据相关联的账户信息。
S303：若区块链系统检测到存在与变更数据相关联的账户信息，则向账户信息对应的目标账户发出提示信息。
其中，步骤S301～步骤S303的具体实现方式，可以参见上述实施例中步骤S201～步骤S203的相关描述，本发明在此不再赘述。
S304：区块链系统接收来自第一账户的携带有第二变更数据的数据变更请求，该数据变更请求用于请求根据第二变更数据对第一账户对应的数据进行变更。其中，该第一账户为至少一个区块链账户中的任一个。
在一个实施例中，第一账户需要对任一数据进行变更时，可以利用第一账户连接区块链系统中的任一节点，并通过该节点向区块链系统发布数据变更请求，该数据变更请求中携带有对任一数据的变更数据(即第二变更数据)。这种情况下，区块链系统可以在接收到该数据变更请求后，从数据变更请求中获取第二变更数据。
S305：区块链系统检测第二变更数据的数据类型。
S306：区块链系统根据预设的智能合约确定数据类型对应的目标信息处理策略，并对数据变更请求执行目标信息处理策略。
在一个实施例中，区块链系统可以预先建立预定义的各个数据类型与信息处理策略的对应关系，并根据对应关系生成上述智能合约。这种情况下，区块链系统检测出第二变更数据的数据类型后，可以在智能合约所指示的对应关系中确定出数据类型对应的目标信息处理策略，进而对该数据变更请求执行该目标信息处理策略。采用本发明，可以针对变更数据的数据类型，执行不同的目标信息处理策略，有利于提高对数据变更的处理效率。其中，上述预设的智能合约所指示的对应关系可以如表2-1所示。
表2-1
数据类型 信息处理策略
Type-1 Stra-01
Type-2 Stra-02
示例性地，预设的智能合约所指示的对应关系如表2-1所示，区块链系统 获取到第二变更数据后，检测到第二变更数据的数据类型为Type-1，则可以根据该智能合约确定出数据类型Type-1对应的目标信息处理策略为Stra-01，进而执行目标信息处理策略Stra-01。
需要说明的是，对于不同应用场景，本发明所描述的中心化系统、区块链系统、第二变更数据的数据类型以及信息处理策略均可以不同。示例性地，当应用场景为贷款系统时，本发明所描述的中心化系统可以为贷款平台，区块链系统可以为应用于贷款的区块链系统，第二变更数据的数据类型可以包括企业销售数据、企业贷款金额等。进一步地，与企业销售数据对应的目标信息处理策略，则可以为区块链系统将第二变更数据发送给与第二变更数据相关联的企业(以下简称相关企业)，那么是否同意数据变更则由相关企业决定。或者，企业贷款金额对应的目标信息处理策略，则可以为区块链系统将第二变更数据发送给贷款平台，那么是否同意数据变更则由贷款平台决定。
其中，区块链系统可以预定义多种数据类型，不同的数据类型各自对应着不同的目标信息处理策略。示例性，本发明可以包括至少一种目标信息处理策略，具体可以包括第一目标信息处理策略、第二目标信息处理策略等。
在一个实施例中，上述预设的智能合约可以包括对第一账户对应数据进行变更的变更条件。这种情况下，区块链系统对数据变更请求执行的目标信息处理策略，可以为向关联账户发送数据变更请求，并获取关联账户针对数据变更请求的反馈信息，如果反馈信息满足变更条件，则根据第二变更数据对第一账户对应的数据进行变更。
其中，上述关联账户可以包括以下至少一种：与第二变更数据相关联的账户和与第一账户相关联的账户。具体地，与第二变更数据相关联的账户可以为预先与第二变更数据具有绑定关系的账户，也可以为在第二变更数据中提取到的账户，也即第二变更数据中包括该账户；与第一账户相关联的账户可以为预先与第一账户具有绑定关系的账户。本发明实施例中，该关联账户可以包含中心化系统的账户，也可以不包含中心化系统的账户，本方案对此不做具体限定。
在一个实施例中，上述反馈信息可以包括关联账户允许数据变更请求的账户数量。在一个实施例中，区块链系统获取到关联账户针对数据变更请求的反馈信息之后，可以对反馈信息进行解析，以确定关联账户允许数据变更请求的 账户数量，在账户数量大于或者等于预设数量阈值时，则确定反馈信息满足变更条件。
在一个实施例中，上述反馈信息还可以包括关联账户允许数据变更请求的百分比。在一个实施例中，区块链系统获取到关联账户针对数据变更请求的反馈信息之后，可以对反馈信息进行解析，以确定关联账户允许数据变更请求的百分比，在百分比大于或者等于预设百分比阈值时，则确定反馈信息满足变更条件。例如，预设百分比阈值为95％，区块链系统对反馈信息进行解析，确定出关联账户允许数据变更请求的百分比为96％，那么则可以确定该反馈信息满足变更条件。
示例性地，如果上述方法应用于保险系统，区块链系统可以应用于该保险系统，来自第一账号的第二变更数据为张三意外险的赔偿金额，具体数额为10万，对第一账号对应数据进行变更的变更条件(即智能合约中包括的变更条件)为允许数据变更请求的账户数量达到5个，关联账户包括number-01、number-02、number-03、number-04、number-05以及number-06。这种情况下，区块链系统可以向number-01、number-02、number-03、number-04、number-05以及number-06发送关于第二变更数据的数据变更请求，各相关账号接收到该数据变更请求后，会发出是否允许该数据变更请求的指示信息，区块链系统统计这些指示信息，确定出这6个关联账户中允许数据变更请求的账户数量达到6个(即反馈信息)，经过判断允许数据变更请求的账户数量大于5，则可以确定反馈信息满足变更条件，进而根据第二变更数据将张三意外险的赔偿金额变更为10万。
在一个实施例中，区块链系统对数据变更请求执行的目标信息处理策略，还可以为向中心化系统发送上述数据变更请求，该数据变更请求用于指示中心化系统在对数据变更请求验证通过后，发出验证通过的响应信息。进一步地，区块链系统可以接收响应信息，并在接收到该响应信息后根据第二变更数据对第一账户对应的数据进行变更。
在一个实施中，区块链系统可以向中心化系统发送来自第一账号的携带有第二数据变更的数据变更请求，中心化系统接收到该数据变更请求后，可以对该数据变更请求进行验证，并在对该数据变更请求验证通过的情况下，向区块 链系统发出验证通过的响应信息，以使得区块链系统接收到该响应信息后，根据第二变更数据对第一账户对应的数据进行变更。
例如，中心化平台为贷款平台，来自第一账户的数据变更请求携带的第二变更数据为企业XYD的贷款金额，其具体数额为2万元。这种情况下，当第一账户的用户想要将企业XYD的贷款金额变更为2万元时，可以通过区块链系统向贷款平台发送数据变更请求，该数据变更请求中携带有第二变更数据，用于请求将企业XYD的贷款金额变更为2万元。进一步地，贷款平台接收到该数据变更请求后，对该数据变更请求进行验证，如果同意将企业XYD的贷款金额变更为2万元，则确定对该数据变更请求验证通过，向区块链系统发出验证通过的响应信息，区块链接收到该响应信息后，则根据第二变更数据将企业XYD的贷款金额变更为2万元。
本发明实施例中，区块链系统可以接收中心化系统发送的第一变更数据，并将第一变更数据更新至所述区块链系统中包括的各个节点并检测是否存在与第一变更数据相关联的账户信息，如果检测到存在与第一变更数据相关联的账户信息，则向账户信息对应的目标账户发出提示信息。进一步地，区块链系统还可以接收来自第一账户的携带有第二变更数据的数据变更请求，并检测第二变更数据的数据类型，进而根据预设的智能合约确定数据类型对应的目标信息处理策略，并对数据变更请求执行目标信息处理策略。采用本发明，一方面可以在不需要对传统数据系统做较大调整的情况下，实现数据基于区块链且结合智能合约的分布式管理；另一方面还可以保留传统数据系统的中心化管理的特权，从而更加满足行业实际需求；又一方面还可以在数据发生变更时通知所变更数据对应的区块链目标账户，使得数据更新的消息及时有效的传达。
本发明实施例还提供了一种计算机可读存储介质，该计算机可读存储介质中存储有程序指令，该程序指令被执行时，用于实现上述实施例中描述的相应方法。
再请参见图4，是本发明实施例的一种基于区块链的数据管理装置的结构示意图，该装置包括用于执行前述如图2或者图3所述的方法的模块。具体地，本实施例的装置包括：收发模块40以及检测模块41，其中：
收发模块40，用于接收所述中心化系统发送的第一变更数据，并将所述第一变更数据更新至所述区块链系统中包括的各个节点；
检测模块41，用于检测是否存在与所述第一变更数据相关联的账户信息；
所述收发模块40，还用于若检测模块检测到存在与所述变更数据相关联的账户信息，则向所述账户信息对应的目标账户发出提示信息，所述提示信息用于提示所述目标账户对应的数据已被变更。
