具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本说明书一个或多个实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本说明书一个或多个实施例的一些方面相一致的装置和方法的例子。
需要说明的是：在其他实施例中并不一定按照本说明书示出和描述的顺序来执行相 应方法的步骤。在一些其他实施例中，其方法所包括的步骤可以比本说明书所描述的更多或更少。此外，本说明书中所描述的单个步骤，在其他实施例中可能被分解为多个步骤进行描述；而本说明书中所描述的多个步骤，在其他实施例中也可能被合并为单个步骤进行描述。
在传统设计领域中，大师或者优秀的设计师会创造设计风格，其他设计师会学习、临摹甚至抄袭这些图形风格，应用在其绘画或设计作品中。这会戳伤原创者的利益，尤其是模仿者拿模仿产品进行了盈利之后，无法监管，也无法进行利益再分配；而对于现有侵权认定，周期长、成本大，很难贯彻。上述问题对原创者的原创地位的认定和分配机制均不够公平。
为解决以上提出的问题，本说明书的一个或多个实施例提供了一种基于区块链的著作权分配方法，应用于包括著作权分配平台节点设备和用户客户端的区块链网络。
本说明书一个或多个实施例所述的区块链网络，具体可指一个各节点设备通过共识机制达成的、具有分布式数据存储结构的P2P网络系统，该区块链内的数据分布在时间上相连的一个个“区块(block)”之内，后一区块包含前一区块的数据摘要，且根据具体的共识机制(如POW、POS、DPOS或PBFT等)的不同，达成全部或部分节点的数据全备份。本领域的技术人员熟知，由于区块链网络系统在相应共识机制下运行，已收录至区块链数据库内的数据很难被任意的节点篡改，例如采用Pow共识的区块链，至少需要全网51％算力的攻击才有可能篡改已有数据，因此区块链系统有着其他中心化数据库系统所无法比拟的保证数据安全、防攻击篡改的特性。由此可知，被收录至区块链的分布式数据库中的数据不会被攻击或篡改，从而保证了存证入区块链的分布式数据库的数据信息的真实可靠性。
区块链网络的示例类型可以包括公有区块链网络、私有区块链网络和联盟区块链网络。尽管术语区块链通常与比特币加密货币网络相关联，但是本文使用的区块链可指代不参考任何特定用例的DLS(分布式账本系统)。
在公有区块链网络中，共识过程由共识网络的节点控制。例如，数百、数千、甚至数百万个实体可以在公有区块链网络中协作，每个实体在公有区块链网络中操作至少一个节点。因此，公有区块链网络可以被认为是相对于参与实体的公有网络。示例公有区块链网络包括比特币网络，比特币网络是对等支付网络。比特币网络利用分布式账本，被称为区块链。然而如上所述，术语区块链通常用于指代不特别参考比特币网络的分布式账本。
通常，公有区块链网络支持公有交易。公有交易与公有区块链网络内的所有节点共享，并存储在全局区块链中。全局区块链是跨所有节点复制的区块链。也就是说，对于全局区块链，所有节点处于完全一致的状态。为了达成共识(例如，同意向区块链添加块)，在公有区块链网络内实施共识协议。示例共识协议包括但不限于，在比特币网络中实施的工作量证明(proof-of-work，POW)。
通常，私有区块链网络提供给特定实体，特定实体集中控制读取和写入权限。该实体控制哪些节点能够参与区块链网络。因此，私有区块链网络通常被称为许可网络，其对允许谁参与网络及其参与水平(例如，仅在某些交易中)施加限制。可以使用各种类型的访问控制机制(例如，现有参与者投票添加新实体，监管机构可以控制准入)。
通常，联盟区块链网络在参与实体中是私有的。在联盟区块链网络中，共识过程由授权的一组节点(联盟成员节点)控制，一个或多个节点由相应的实体(例如，企业)操作。例如，由十(10)个实体(例如，企业)组成的联盟可以操作联盟区块链网络，每个实体在该联盟区块链网络中操作至少一个节点。因此，就参与实体而言，联盟区块链网络可以被认为是私有网络。在一些示例中，每个实体(节点)必须对每个块进行签名，以使该块有效并将有效的块添加到区块链。在一些示例中，至少实体(节点)的子集(例如，至少7个实体)必须对每个块进行签名以使该块有效，并且将有效的块添加到区块链。
可以预期，本说明书所提供的实施方式能够在任何合适类型的区块链网络中实现。
本说明书一个或多个实施例所述的节点(或节点设备)是指可通过遵循相应节点协议、运行节点协议程序的安装来加入该区块链，作为该区块链的节点。本领域的技术人员通常将具有区块链分布式数据库的数据全备份的节点设备称为全节点，将具有区块链分布式数据库的部分备份数据(如仅有区块头的数据)的节点设备称为轻节点等。在本说明书的一个或多个实施例中，并不限定上述著作权分配平台节点设备的节点类型。
本说明书中一个或多个实施例所述的著作权分配平台用以接收平台用户提供的作品或作品相关的设计数据、并为作品对应的著作权进行分配。本说明书所述的作品包括图片等设计作品、文字作品、音频视频作品等具备作者独有的创作风格的作品。基于平台用户提供的目标作品的原创性(是否与已有作品构成风格近似)，平台用户可以在该平台上获得目标作品的一定比例的著作权，或按照上述比例享有基于目标作品的使用而获得收益的权利。
在本说明书提供的一个或多个实施例中，平台用户实体通过在终端运行客户端安装程序加入到上述区块链网络中来，上述客户端安装程序可以为区块链节点设备的安装程序，相应地，该用户客户端也作为上述区块链的节点设备，在备份区块链的分布式数据库副本时向其邻近的节点设备(如上述著作权分配平台节点设备)发起数据获取请求，或通过向其邻近的节点设备进行数据广播而向区块链上发布数据；上述客户端安装程序也可以是与联盟区块链链中的一联盟成员节点设备(如上述著作权分配节点设备)连接的、被控制访问的区块链用户客户端程序，相应地，该客户端由于不具备直接访问区块链的分布式数据库的权限，而一般不被作为上述区块链的节点，需要向与其连接的一个或多个联盟成员节点进行具有权限获知的数据请求。本说明书并不限定上述用户客户端是否为上述区块链的节点设备。如上所述，上述客户端无论作为区块链节点设备还是联盟成员节点的用户端设备，可通过与著作权分配节点设备通信连接而获取存储于区块链的分布式数据库中的数据，或通过与著作权分配节点设备通信连接向区块链的分布式数据库中发送数据。
如图1所示，本说明书所提供的一种基于区块链的著作权分配方法实施方式中，该方法包括：
步骤102，所述区块链的节点设备接收目标交易，所述目标交易包括目标作品的设计数据和与所述目标作品对应的目标著作权用户的身份标识。
本说明书中一个或多个实施方式中所描述的交易(transaction)，是指通过区块链的节点设备创建，并需要最终发布至区块链的分布式数据库中的一笔数据。其中，区块链中的交易，存在狭义的交易以及广义的交易之分。狭义的交易是指用户向区块链发布的一笔价值转移；例如，在传统的比特币区块链网络中，交易可以是用户在区块链中发起的一笔转账。而广义的交易是指用户实体通过节点向区块链发布的一笔具有业务意图的业务数据。
本实施方式所述的目标交易，可包括目标作品的设计数据和与目标作品对应的目标著作权用户的身份标识，该目标著作权用户可以为上述目标作品的设计者、或享有目标作品的著作权的权利人、或享有目标作品的收益权的权利人等，上述目标著作权用户可以为一个，也可以为多个；目标著作权用户的身份标识可以包括该目标著作权用户在上述区块链网络的账户地址、公钥、CA证书号码、或目标著作权用户的身份证号码等具有唯一性的识别标识，在本说明书中不作限定。值得注意的是，上述目标作品的设计数据可以为目标作品本身，如文学作品、设计作品、视频或音频作品等，也可以是体现目 标作品独创性的设计特征数据，如体现图形设计作品独创性风格的圆角角度值、描边粗度值、大小尺寸值、颜色色号色素值，等等。
本实施方式并不限定上述目标交易的发送方身份。如上所述，当用户客户端作为上述区块链的节点设备时，用户客户端可直接向上述区块链发送上述目标交易，并经上述区块链的共识验证后，将上述目标交易收录入该区块链的分布式数据库中。在又一示出的实施方式中，上述实施方式所述的区块链为联盟链，上述著作权分配平台节点设备为联盟成员节点；则上述用户客户端作为上述著作权分配平台的用户端与所述著作权分配平台节点设备通信连接；用户通过向上述著作权分配平台发送目标作品设计数据后，由著作权分配平台节点设备将设计数据和目标著作权用户的身份标识整理成上述目标交易并向区块链发送。
由用户客户端直接向区块链发送目标交易的实施方式，相比于由平台节点设备在收集用户客户端信息后向区块链发送目标交易的实施方式，流程简化，数据真实性更强；但对用户客户端的硬件要求较高，且由于未经平台的数据处理，可能由于发送一些无效数据而造成区块链分布式数据库的空间浪费。本领域的技术人员可以从实际业务需求出发，搭建与业务模式契合的区块链模式(如联盟链模式)，并为用户客户端分配相应的参与方权限。
步骤104，调用第一智能合约，执行所述第一智能合约声明的设计相似性对比逻辑和著作权分配逻辑，将所述目标作品的设计数据与所述区块链的分布式数据库存储的第一作品的设计数据进行相似性对比以获得第一目标相似度，并基于所述第一目标相似度在所述目标著作权用户和所述第一作品对应的第一用户之间进行所述目标作品的著作权分配。
为进一步提供本说明书的实施方式的背景，在区块链网络中，可以开发、测试和部署应用程序以在区块链网络内执行。示例应用程序可以包括但不限于智能合约。智能合约可以被描述为具有影响各方的合约条款的现实世界的法律合约的数字表示。智能合约被实施、存储、更新(根据需要)、并在区块链网络内执行。与智能合约相关联的合约方(例如，买方和卖方)可被表示为区块链网络中的节点。
在一些示例中，智能合约可以存储数据，该数据可以用于记录信息、事实、关联、余额以及实现合约执行逻辑所需的任何其他信息。智能合约可以被描述为由函数组成的计算机可执行程序，其中可以创建该智能合约的实例(instance)，调用函数以执行智能合约声明的逻辑。
在技术方面，可以基于对象和面向对象的类来实现智能合约。例如，智能合约的条款和组件可以表示为由实现智能合约的应用程序处理的对象。智能合约(或智能合约中的对象)可以像其他面向对象的对象一样调用另一个智能合约(或同一智能合约中的对象)。例如，对象进行的调用可以是创建、更新、删除、传播或与另一个类的对象通信的调用。对象之间的调用可以由函数、方法、应用程序编程接口(application programming interface，API)或其他调用机制实现。例如，第一对象可以调用函数来创建第二对象。
因此，基于以上关于智能合约的描述，本说明书提供的一个或多个实施例所述的上述目标交易作为第一智能合约的调用交易，还可包括所调用的第一智能合约地址、或所调用执行的逻辑函数名称等其他参数，在此不再赘述。通过调用上述第一智能行业，上述目标作品的设计数据及目标著作权用户的身份标识等数据信息，也被存储在该第一智能合约中。
上述实施例所述的已有作品的设计数据基于之前已完成的第一智能合约的调用交易，被存储在上述第一智能合约中，上述已有作品的数量不限。第一智能合约将所述目标作品的设计数据与所述第一智能合约存储的已有作品的设计数据进行相似性对比以获得目标相似度，相应地，上述目标相似度既可以是与一部相似的已有作品的设计数据相比所得的一个目标相似度，也可以是与多部相似的已有作品的设计数据相比所得的多个目标相似度。
本领域的技术人员可以根据目标作品的实际表现形式、或具体的业务应用场景设计上述相似性对比逻辑。例如，UI设计行业内通常会规定图标(icon)元素的设计规则及设计特征值，上述设计规则包括图标元素的设计尺寸、图层个数、轮廓线尺寸等参数的规定，并提炼出可体现图标元素的设计原创性的几个设计特征值：如点线尺寸、圆角弧度、拐角角度、色度、对比度等等，上述第一智能合约可基于上述目标作品的设计数据和预设的设计规则，获取上述目标作品的至少一个目标设计特征值；在基于所述已有作品的设计数据和所述预设的设计规则，获取所述已有作品的至少一个已有设计特征值；对比所述至少一个目标设计特征值和所述至少一个已有设计特征值，以获得至少一个目标相似度。
又如，对于音乐类的音频作品，可以基于音乐创作的设计规则，获取包括节拍节奏、或音律音程等设计特征值，来对比目标作品和已有作品的相似度；对于视频类的作品，可以基于视频的剧情类型、设计思路、演绎风格等设计规则获取到相应的设计特征值，来对比目标作品和已有作品的相似度；等等。
上述的设计相似性对比逻辑较适用于设计规则明确、设计特征值易获取的作品类型，对于开放性大、发散性强、难以总结设计规则及获得设计特征值的作品类型，可以借助于人工智能如无监督的机器学习算法(如生成对抗网络GAN)来计算执行上述目标作品的设计数据与已有作品的设计数据的相似度计算，从而获得所述目标相似度。
关于上述无监督的机器学习算法的具体计算逻辑可由本领域的技术人员基于目标作品的类型而具体设置，本说明书对此不作限定。
上述第一智能合约在计算获得上述目标相似度后，即可基于预设的分配逻辑，基于所述目标相似度在所述目标著作权用户和所述已有作品对应的著作权用户之间进行所述目标作品的著作权分配——当目标相似度达到预设阈值后，已有作品对应的著作权用户(作为原创者)可实现对目标著作权用户(作为模仿者)产出目标作品的部分著作权；当目标相似度未达到预设阈值时，目标著作权用户由于其目标作品不构成对已有作品的相似性模仿而享有全部的著作权。关于部分著作权的分配比例，可基于目标作品的类型而具体设置，如可采用阶梯式分配逻辑，目标相似度达到第一阈值(95％-100％)时，已有作品对应的著作权用户可获得目标作品50％的著作权；低于第二阈值(80％)时，已有作品对应的著作权用户不获得目标作品的著作权；居于第一和第二阈值之间，已有作品对应的著作权用户可获得目标作品20％的著作权，等等。
由于上述第一智能合约需经过区块链的节点设备的共识验证方可部署上链执行，因此，关于上述设计相似性对比逻辑和著作权分配逻辑的制定可采用行业内的惯例或其他通用约定，以确保上述逻辑制定的公平合理性。相比于由著作权分配平台独立制定并执行著作权分配逻辑的实施方式，本说明书提供的基于区块链的著作权分配方法的相似性对比逻辑机分配逻辑更加透明化、公开化，有效防止了平台内部操作带来的显失公平性；且第一智能合约可以在任何时候基于调用请求而执行，大大提升了著作权分配的执行效率。
上述目标作品的著作权分配结果可以以第一智能合约的执行输出事件的方式存储于交易日志中，被存储在区块链的分布式数据库中；以此分配结果为基础，上述目标著作权用户和上述已有作品的著作权用户可基于目标作品的著作权比例享受该目标作品的使用收益权。
因此，在又一示出的实施方式中，上述目标著作权用户和上述已有作品的著作权用户获取收益的方法包括：接收目标收益交易，所述目标收益交易包括用户用于使用目标作品而支付的第一数量的虚拟资源；调用所述第一智能合约，执行所述第一智能合约声 明的基于所述目标作品的著作权分配进行虚拟资源分配的逻辑，向所述目标著作权用户和所述已有作品对应的著作权用户分配第二数量的虚拟资源。
本说明书提供的一个或多个实施方式中所述的虚拟资源，可以包括区块链上流通的数字资产，例如类似于比特币、以太币等在上述区块链上定义流通的数字货币；还可对应于区块链外的资产，如现金、证券、优惠券、房产等链外资产，等等。本领域的技术人员可以从实际的业务场景需求出发，设计上述虚拟资源的具体表现形式，本发明对此不做限定。
当然，对上述目标著作权用户和上述已有作品的著作权用户基于其享有的目标作品的著作权而执行的收益分配逻辑，可以由另一智能合约，如第二智能合约执行；相应的，上述目标著作权用户和上述已有作品的著作权用户获取收益的方法包括：接收目标收益交易，所述目标交易包括用户用于使用目标作品而支付的第一数量的虚拟资源；调用第二智能合约，执行所述第二智能合约声明的对所述第一智能合约的调用逻辑，基于所述第一智能合约执行的所述目标作品的著作权分配，向所述目标著作权用户和所述已有作品对应的著作权用户分配第二数量的虚拟资源。通过第二智能合约对第一智能合约的调用，可获得目标作品的现有著作权分配结果，并基于第二智能合约声明的收益分配逻辑对享有目标作品全部或部分著作权的用户进行收益分配。相对于由第一智能合约全部实现著作权分配及收益分配的实施方式，可降低对第一智能合约的更新或管理成本，且收益分配方式更加灵活。
上述第一智能合约或第二智能合约均可由上述著作权分配平台编译部署上链，并由上述著作权分配平台负责第一智能合约或第二智能合约的维护和升级。为了保证著作权分配平台的盈利或成本支出，上述第一数量可不小于上述第二数量。
基于本说明书上述一个或多个实施例所提供的基于区块链的著作权分配方法，目标作品的现有创作者(目标著作权用户)和与目标作品符合预设的相似度的已有作品的创作者(与已有作品对应的著作权用户)均可获得目标作品的部分著作权，或基于上述部分著作权而获得相应的收益；该方法既积极地鼓励了原创者，又数值化地分析了模仿者所作出的创造性工作，一定程度上也给予了对模仿者所做出的创造性工作的鼓励，因此更加鼓励了用户对创造性工作的投入和支持。
在上述一个或多个实施例所提供的基于区块链的著作权分配方法中，关于已有作品对应的著作权用户的认定，通常是由已有作品被区块链(或第一智能合约)收录的时间早于目标作品被收录的时间来确定的。值得注意的是，在一些特殊的事件情况下，如恰 好用户A比用户B提前一小时向著作权分配平台公布其作品的设计数据，但实际上用户B创造的浏览量或者交易价值远远大于用户A等事件情况下，上述著作权分配平台节点设备可启动著作权归属公投程序，向区块链上发布著作权归属公投交易，上述著作权归属公投交易包括与目标作品的设计数据对应的多个著作权用户；调用第一智能合约，执行所述第一智能合约声明的著作权归属公投逻辑，在预设的时长内接收公投用户发送的投票交易，基于所述投票交易，在所述多个著作权用户中为所述目标作品分配著作权。
上述特殊事件前提下的著作权分配方法可作为对上述一个或多个实施例所提供的基于区块链的著作权分配方法的补充，从而为目标作品的著作权分配建立起更加公平合理的机制。
