基于区块链的知识管理方法、终端及服务器
技术领域
本发明涉及物联网技术领域，尤其涉及一种基于区块链的知识管理方法、终端及服务器。
背景技术
区块链(Blockchain)是比特币的一个重要概念，区块链是一串使用密码学方法相关联产生的数据块，每一个数据块中包含了过去十分钟内所有比特币网络交易的信息，用于验证其信息的有效性(防伪)和生成下一个区块。
区块链提供了一种去中心化的、无需信任积累的信用建立范式。区块链技术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，用数据区块(Block)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者交易项目都记录在一个云系统之上，理论上实现了数据传输中对数据的自我证明。
区块链可以应用于数据存储、数据鉴证以及资产管理等领域，但是现有的区块链无法保证知识信息记录的及时有效性。
发明内容
本发明的主要目的在于提供一种基于区块链的知识管理方法、终端及服务器，能够保证知识信息记录的及时有效性。
为实现上述目的，本发明提供一种基于区块链的知识管理方法，包括以下步骤：发送数据信息至服务器；接收服务器根据数据信息的条目信息创建的唯一码；根据条目信息以及唯一码结合形成数据包并发送至服务器；接收服务器为数据包加盖的时间戳；将包含时间戳的数据包写入区块链。
优选地，根据条目信息以及唯一码结合形成数据包并发送至服务器的步骤，包括：对条目信息进行哈希运算获得哈希码；将唯一码与哈希码结合形成数据包并发送至服务器。
优选地，基于区块链的知识管理方法还包括：发送查询信息至服务器；接收服务器根据查询信息进行唯一码的筛选而获得的条目信息；选择条目信息进行下载。
此外，为实现上述目的，本发明还提供一种终端，包括：数据发送模块，用于发送数据信息至服务器；创建模块，与发送模块连接，用于接收服务器根据数据信息的条目信息创建的唯一码；数据包形成模块，与创建模块连接，用于根据条目信息以及唯一码结合形成数据包并发送至服务器；时间戳接收模块，与数据包形成模块连接，用于接收服务器为数据包加盖的时间戳；写入模块，与时间戳接收模块连接，用于将包含时间戳的数据包写入区块链。
优选地，数据包形成模块包括：哈希码获取模块，与创建模块连接，用于对条目信息进行哈希运算获得哈希码； 结合模块，与哈希码获取模块连接，用于将唯一码与哈希码结合形成数据包并发送至服务器。
此外，为实现上述目的，本发明还提供一种终端，包括：第一存储器、第一处理器及存储在第一存储器上并可在第一处理器上运行的第一计算机程序，第一计算机程序被第一处理器执行时实现前述的基于区块链的知识管理方法的步骤。
此外，为实现上述目的，本发明还提供一种基于区块链的知识管理方法，包括以下步骤：接收终端发送的数据信息；采用预设编码方式为数据信息中的每一条目信息创建唯一码；为终端根据条目信息以及唯一码结合形成的数据包加盖时间戳；将时间戳发送至终端，以使终端将包含时间戳的数据包写入区块链。
优选地，基于区块链的知识管理方法还包括：接收终端发送的查询信息；根据查询信息进行唯一码的筛选并获得的条目信息；将条目信息发送至终端以使终端选择条目信息进行下载。
此外，为实现上述目的，本发明还提供一种服务器，包括：数据接收模块，用于接收终端发送的数据信息；唯一码创建模块，与数据接收模块连接，用于采用预设编码方式为数据信息中的每一条目信息创建唯一码；时间戳加盖模块，与唯一码创建模块连接，用于为终端根据条目信息以及唯一码结合形成的数据包加盖时间戳；时间戳发送模块，与时间戳加盖模块连接，用于将时间戳发送至终端，以使终端将包含时间戳的数据包写入区块链。
此外，为实现上述目的，本发明还提供一种服务器，包括：第二存储器、第二处理器及存储在第二存储器上并可在第二处理器上运行的第一计算机程序，第一计算机程序被第二处理器执行时实现前述的基于区块链的知识管理方法的步骤。
本发明通过发送数据信息至服务器；接收服务器根据数据信息的条目信息创建的唯一码；根据条目信息以及唯一码结合形成数据包并发送至服务器；接收服务器为数据包加盖的时间戳；将包含时间戳的数据包写入区块链，由于哈希运算信息一旦被写入区块链，则难以更改，一旦出现篡改，就算是一个字符的变化，都会导致运算结果出现显著变化，在知识产权保护领域中，哈希码配合时间戳能够提供一种可靠的时间证明，能够保证知识信息记录的及时有效性。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的主要解决方案是：终端发送数据信息至服务器，服务器为数据信息中的第一条目信息创建唯一码；终端根据条目信息以及唯一码结合形成数据包；服务器应终端请求为数据包加盖的时间戳，终端将包含时间戳的数据包写入区块链。
由于现有技术区块链无法保证知识信息记录的及时有效性，本发明提供一种解决方案，终端发送数据信息至服务器，服务器为数据信息中的第一条目信息创建唯一码；终端根据条目信息以及唯一码结合形成数据包；服务器应终端请求为数据包加盖的时间戳，终端将包含时间戳的数据包写入区块链能够保证知识信息记录的及时有效性。
如图1所示，图1是本发明实施例方案涉及的硬件运行环境的终端的结构示意图。
本发明实施例终端可以是PC，也可以是智能手机、平板电脑、电子书阅读器、MP3（Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3）播放器、MP4（Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面3）播放器、便携计算机等具有显示功能的可移动式终端设备。
如图1所示，该终端可以包括：第一处理器1001，例如CPU，第一网络接口1004，第一用户接口1003，第一存储器1005，第一通信总线1002。其中，第一通信总线1002用于实现这些组件之间的连接通信。第一用户接口1003可以包括显示屏（Display）、输入单元比如键盘（Keyboard），可选的第一用户接口1003还可以包括标准的有线接口、无线接口。第一网络接口1004可选的可以包括标准的有线接口、无线接口（如WI-FI接口）。第一存储器1005可以是高速RAM存储器，也可以是稳定的存储器（non-volatile memory），例如磁盘存储器。第一存储器1005可选的还可以是独立于前述第一处理器1001的存储装置。
可选地，终端还可以包括摄像头、RF（Radio Frequency，射频）电路，传感器、音频电路、WiFi模块等等。其中，传感器比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示屏的亮度，接近传感器可在移动终端移动到耳边时，关闭显示屏和/或背光。作为运动传感器的一种，重力加速度传感器可检测各个方向上（一般为三轴）加速度的大小，静止时可检测出重力的大小及方向，可用于识别移动终端姿态的应用（比如横竖屏切换、相关游戏、磁力计姿态校准）、振动识别相关功能（比如计步器、敲击）等；当然，移动终端还可配置陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
本领域技术人员可以理解，图1中示出的终端结构并不构成对终端的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图1所示，作为一种计算机存储介质的第一存储器1005中可以包括第一操作系统、第一网络通信模块、第一用户接口模块以及第一计算机程序。
在图1所示的终端中，第一网络接口1004主要用于连接后台服务器，与后台服务器进行数据通信；第一用户接口1003主要用于连接客户端（用户端），与客户端进行数据通信；而第一处理器1001可以用于调用第一存储器1005中存储的第一计算机程序，并执行以下操作：
发送数据信息至服务器；
接收服务器根据数据信息的条目信息创建的唯一码；
根据条目信息以及唯一码结合形成数据包并发送至服务器；
接收服务器为数据包加盖的时间戳；
将包含时间戳的数据包写入区块链。
进一步地，第一处理器1001可以调用第一存储器1005中存储的第一计算机程序，还执行以下操作：
对条目信息进行哈希运算获得哈希码；
将唯一码与哈希码结合形成数据包并发送至服务器。
进一步地，第一处理器1001可以调用第一存储器1005中存储的第一计算机程序，还执行以下操作：
发送查询信息至服务器；
接收服务器根据查询信息进行唯一码的筛选而获得的条目信息；
选择条目信息进行下载。
参照图2，本发明第一实施例提供一种基于区块链的知识管理方法，所述基于区块链的知识管理方法包括：
步骤S10，发送数据信息至服务器。
在步骤S10之前，将用户身份信息传输至服务器创建一对密钥，其中，密钥包括私钥和公钥；将经私钥加密的登录信息发送至服务器进行登录。具体地，终端提供用户身份信息等内容注册，并发送至服务器以验证用户身份信息，进而使服务器为用户创建一对密钥。其中，公钥全网公开，私钥用户自己保存。用户需要进行登录时，终端使用私钥加密登录信息并发送至服务器，以使服务器能够采用相应终端的公钥解密并认证登录信息。
在步骤S10中，终端对需要发送的数据信息进行高级加密标准(Advanced Encryption Standard，AES)等方式的加密，并将加密后的数据信息发送至服务器。在本发明实施例中，数据信息可以包括文本、图片、音频、视频等信息内容。
步骤S11，接收服务器根据数据信息的条目信息创建的唯一码。
其中，唯一码包括身份、条目类别、条目摘要的至少之一。当然唯一码还可以包括其他信息，在此不再赘述。
步骤S12，根据条目信息以及唯一码结合形成数据包并发送至服务器。
在步骤S12中，对条目信息进行哈希运算获得哈希码；将唯一码与哈希码结合形成数据包并发送至服务器。由于哈希运算信息一旦被写入区块链，则难以更改，一旦出现篡改，就算是一个字符的变化，都会导致运算结果出现显著变化，在知识产权保护领域中，哈希码配合时间戳能够提供一种可靠的时间证明，能够保证知识信息记录的及时有效性。
步骤S13，接收服务器为数据包加盖的时间戳。
具体地，首先向服务器发送时间戳请求信息，以使服务器根据该时间戳请求信息为数据包加盖时间戳，终端接收该时间戳。
步骤S14，将包含时间戳的数据包写入区块链。
如此完成基于区块链技术的数据存储与管理，能够保证知识信息记录的及时有效性。
在本发明实施例中，区域链的高冗余存储（每个节点存储一份数据）、去中心化、高安全性和隐私保护等特点使其特别适合存储和保护重要隐私数据，以避免因中心化机构遭受攻击或权限管理不当而造成的大规模数据丢失或泄露。与比特币交易数据类似地，任意数据均可通过哈希运算生成相应的梅克尔（Merkle）树并打包记入区块链，通过内共识节点的哈希运算和非对称加密技术来保证安全性。区块链的多重签名技术可以灵活配置数据访问的权限，例如必须获得指定5个人中3个人的私钥授权才可获得访问权限。另外，利用区块链来存储个人健康数据（如电子病历、基因数据等）是极具前景的应用领域，此外存储各类重要电子文件（视频、图片、文本等）乃至人类思想和意识等也可以有一定应用空间。
另外，区块链数据带有时间戳、由共识节点共同验证和记录、不可篡改和伪造，这些特点使得区块链可以永久地安全存储由政府机构核发的各类许可证、登记表、执照、证明、认证和记录等，并可在任意时间方便地证明某项数据在存在性和一定程度上的真实性。
区块链在资产管理领域能够实现有形和无形资产的确权、授权和实时监控。对于无形资产来说，基于时间戳技术和不可篡改等特点，可以将区块链技术应用于知识产权保护、域名管理、积分管理等领域；而对有形资产来说，通过结合物联网技术为资产设计唯一标识并部署到区块链上，能够形成“数字智能资产”，实现基于区块链的分布式资产授权和控制。例如，通过对房屋、车辆等实物资产的区块链密钥授权，可以基于特定权限来发放和回收资产的使用权，有助于爱彼迎（AirBed and Breakfast，Airbnb）等房屋租赁或车辆租赁等商业模式实现自动化的资产交接；通过结合物联网的资产标记和识别技术，还可以利用区块链实现灵活的供应链管理和产品溯源等功能。
在本实施例中，终端需要进行信息查询时，终端首先进行用户登录，登录方法与前者相同，不再赘述。然后终端发送查询信息至服务器；接收服务器根据查询信息进行唯一码的筛选而获得的条目信息；选择条目信息进行下载。其中，查询信息包括身份信息、存储时间等。
在本实施例中，通过发送数据信息至服务器；接收服务器根据数据信息的条目信息创建的唯一码；根据条目信息以及唯一码结合形成数据包并发送至服务器；接收服务器为数据包加盖的时间戳；将包含时间戳的数据包写入区块链，由于哈希运算信息一旦被写入区块链，则难以更改，一旦出现篡改，就算是一个字符的变化，都会导致运算结果出现显著变化，在知识产权保护领域中，哈希码配合时间戳能够提供一种可靠的时间证明，能够保证知识信息记录的及时有效性。
进一步的，参照图3，本发明还提供一种终端，基于上述图2所示的实施例，所述终端10包括：数据发送模块11、创建模块12、数据包形成模块13、时间戳接收模块14以及写入模块15。数据发送模块11用于发送数据信息至服务器。创建模块12与发送模块11连接，用于接收服务器根据数据信息的条目信息创建的唯一码。数据包形成模块13与创建模块12连接，用于根据条目信息以及唯一码结合形成数据包并发送至服务器。时间戳接收模块14与数据包形成模块13连接，用于接收服务器为数据包加盖的时间戳。写入模块15与时间戳接收模块14连接，用于将包含时间戳的数据包写入区块链，如此，能够保证知识信息记录的及时有效性。

在本发明实施例中，数据发送模块11发送数据信息至服务器时，对需要发送的数据信息进行高级加密标准(Advanced Encryption Standard，AES)等方式的加密，并将加密后的数据信息发送至服务器。在本发明实施例中，数据信息可以包括文本、图片、音频、视频等信息内容。
在本发明实施例中，时间戳接收模块14接收服务器为数据包加盖的时间戳之前，终端10首先向服务器发送时间戳请求信息，以使服务器根据该时间戳请求信息为数据包加盖时间戳，进而时间戳接收模块14接收该时间戳。
继续参照图4，终端10包括：查询信息发送模块18、条目信息接收模块19以及下载模块101。终端10需要进行信息查询时，终端10首先进行用户登录，登录方法与前者相同，不再赘述。然后查询信息发送模块18与登录信息发送模块17连接，用于发送查询信息至服务器；条目信息接收模块19与查询信息发送模块18连接，用于接收服务器根据查询信息进行唯一码的筛选而获得的条目信息；下载模块101与条目信息接收模块19连接，用于选择条目信息进行下载。其中，查询信息包括身份信息、存储时间等。

发送数据信息至服务器；
接收服务器根据数据信息的条目信息创建的唯一码；

进一步地，所述第一计算机程序被处理器执行时还实现如下操作：
发送查询信息至服务器；
接收服务器根据查询信息进行唯一码的筛选而获得的条目信息；
选择条目信息进行下载。
参照图5，本发明第二实施例提供一种基于区块链的知识管理方法，所述基于区块链的知识管理方法包括：
步骤S20：接收终端发送的数据信息。
其中，数据信息可以包括文本、图片、音频、视频等信息内容。
在步骤S20之前，接收终端发送的用户身份信息；根据用户身份信息创建一对密钥，其中，密钥包括私钥和公钥；接收终端发送的经私钥加密的登录信息，并应用公钥认证登录信息。在本实施例中，终端提供用户身份信息等内容注册，服务器接收终端发送的用户身份信息，并验证该用户身份信息，从而创建一对密钥。其中，公钥全网公开，私钥用户自己保存。用户需要进行登录时，终端使用私钥加密登录信息并发送至服务器，服务器采用相应终端的公钥解密并认证登录信息。
步骤S21：采用预设编码方式为数据信息中的每一条目信息创建唯一码。
其中，唯一码包括身份、条目类别、条目摘要的至少之一。当然唯一码还可以包括其他信息，在此不再赘述。在步骤S21之前，需要对接收数据信息进行解密审核。
步骤S22：为终端根据条目信息以及唯一码结合形成的数据包加盖时间戳。
在步骤S22中，服务器首先接收终端发送的时间戳请求，进而应该时间戳请求为数据包加盖时间戳。
在本发明实施例中，数据包的形成是终端对条目信息进行哈希运算获得哈希码，进而将唯一码与哈希码结合形成的。由于哈希运算信息一旦被写入区块链，则难以更改，一旦出现篡改，就算是一个字符的变化，都会导致运算结果出现显著变化，在知识产权保护领域中，哈希码配合时间戳能够提供一种可靠的时间证明，能够保证知识信息记录的及时有效性。
步骤S23：将时间戳发送至终端，以使终端将包含时间戳的数据包写入区块链。如此完成基于区块链技术的数据存储与管理，能够保证知识信息记录的及时有效性。

在本实施例中，数据信息可以包括文本、图片、音频、视频等信息内容。唯一码包括身份、条目类别、条目摘要的至少之一。当然唯一码还可以包括其他信息，在此不再赘述。唯一码创建模块22在采用预设编码方式为数据信息中的每一条目信息创建唯一码之前，需要对接收数据信息进行解密审核。而时间戳加盖模块23是应终端的时间戳请求为数据包加盖时间戳。
在本发明实施例中，数据包的形成是终端对条目信息进行哈希运算获得哈希码，进而将唯一码与哈希码结合形成的。由于哈希运算信息一旦被写入区块链，则难以更改，一旦出现篡改，就算是一个字符的变化，都会导致运算结果出现显著变化，在知识产权保护领域中，哈希码配合时间戳能够提供一种可靠的时间证明，能够保证知识信息记录的及时有效性。
