Description

一种通过网页监测对网页进行区块链存证的方法及装置 技术领域
本说明书实施例涉及信息技术领域,尤其涉及一种通过网页监测对网页进行区块链存证的方法及装置。
背景技术
目前,用户出于网络证据保全的需要,可以借助区块链技术,对呈现了网络证据的网页进行存证。例如,在版权保护领域,区块链存证机构可以应版权人的请求,对侵权网页(呈现了侵权作品的网页)进行截图并存证,为后续的维权环节保全证据。
在实践中,网页所呈现的内容往往是动态变化的,用户有时需要对网页进行持续关注,以便选择在合适的实际对该网页进行区块链存证。
还是以版权保护领域为例说明。例如,假设网页不仅呈现了侵权作品,还会呈现了与侵权作品的相关统计量,如下载量、阅读量等,那么,版权人出于自身利益的考虑,可以持续关注该网页,在发现侵权作品的下载量达到某个较大数量时,对该网页进行区块链存证,以便为后续在维权环节要求较大的侵权赔偿数额提供证据支持。
又如,假设网页呈现的作品已经经过版权人授权,但是该授权即将过期,那么,版权人可以持续关注该网页,一旦发现授权已过期而该网页仍未撤下该作品,就立刻对该网页进行区块链存证,及时保全证据。
基于现有技术,需要一种对版权人而言更为便利的网页存证方法。
发明内容
为了解决现有的网页存证方法对版权人而言不够便利的问题,本说明书实施例提供一种通过网页监测对网页进行区块链存证的方法及装置,技术方案如下:
根据本说明书实施例的第1方面,提供一种通过网页监测对网页进行区块链存证的方法,包括:
接收用户发送的网页地址,并访问所述网页地址对应的目标网页;
从所述目标网页的文档中提取标签;
从提取的标签中确定所述用户指定的标签,作为指定标签;以及获取所述用户指定的存证触发条件;
针对所述指定标签进行监测,并当监测到所述指定标签所标记的文档内容满足所述存证触发条件时,对所述目标网页进行区块链存证。
根据本说明书实施例的第2方面,提供一种通过网页监测对网页进行区块链存证的装置,包括:
接收模块,接收用户发送的网页地址,并访问所述网页地址对应的目标网页;
提取模块,从所述目标网页的文档中提取标签;
确定获取模块,从提取的标签中确定所述用户指定的标签,作为指定标签;以及获取所述用户指定的存证触发条件;
监测存证模块,针对所述指定标签进行监测,并当监测到所述指定标签所标记的文档内容满足所述存证触发条件时,对所述目标网页进行区块链存证。
本说明书实施例所提供的技术方案,区块链存证方的服务器可以应版权人的请求,一方面从目标网页的文档中确定出版权人指定的标签进行监测,另一方面获取版权人指定的存证触发条件。区块链存证方的服务器当监测到版权人指定的标签所标记的文档内容满足所述存证触发条件时,就会触发一次对目标网页的区块链存证操作。如此,版权人通过指定标签与指定存证触发条件,将监测目标网页的任务交由区块链存证方的服务器执行。版权人不需要耗费精力持续关注目标网页的动态,对版权人而言更为便利。
应当理解的是,以上的一般描述和后文的细节描述仅是示例性和解释性的,并不能限制本说明书实施例。
此外,本说明书实施例中的任一实施例并不需要达到上述的全部效果。

具体实施方式
为了使本领域技术人员更好地理解本说明书实施例中的技术方案,下面将结合本说明书实施例中的附图,对本说明书实施例中的技术方案进行详细地描述,显然,所描述的实施例仅仅是本说明书的一部分实施例,而不是全部的实施例。基于本说明书中的实施例,本领域普通技术人员所获得的所有其他实施例,都应当属于保护的范围。
以下结合附图,详细说明本说明书各实施例提供的技术方案。
图1是本说明书实施例提供的一种通过网页监测对网页进行区块链存证的方法的流程示意图,包括以下步骤:
S100:接收用户发送的网页地址,并访问所述网页地址对应的目标网页。
本方法的执行主体一般是区块链存证方的服务器。在后文中,为了描述的方便,以“存证服务器”代指“区块链存证方的服务器”。
所述区块链存证方可以是提供区块链存证服务的机构。所述区块链存证方可以是区块链网络中的节点,对外受理数据存证请求,基于数据存证请求获取需要存证的数据,然后基于需要存证的数据构建数据存证交易并广播,此外,还会参与区块链网络中的各节点间的共识,以便将需要存证的数据写入自身维护的区块链(共享账本)中。
所述区块链存证方也可以是不是区块链网络中的节点,而是负责代理受理数据存证请求,对需要存证的数据进行一定的处理(如对需要存证的网页进行截图并哈希化)后,将处理结果提交给区块链网络进行存证。
图1所示的方法可以应用于版权侵权证据保全的场景,也可以应用于其他领域的证据保全的场景。下文将以版权侵权证据保全的场景为例,对本方案进行说明。本领域技术人员应当理解,在其他领域的证据保全的场景下,也可以通过图1所示的方法流程,通过网页监测实现对网页的区块链存证。
在版权侵权证据保全的场景下,所述用户一般是持有作品版权的版权人。所述用户当发现某个呈现了侵权作品的网页(目标网页)时,可以通过浏览器访问存证服务器,并将目标网页的网页地址提供给存证服务器,由存证服务器对目标网页进行访问。
S102:从所述目标网页的文档中提取标签。
众所周知,网页实际上是基于超文本标记语言(Hyper Text Markup Language,HTML)文档进行加载的,本文中所述的文档一般是指网页的HTML文档。在HTML文档中,使用若干HTML标签对不同部分的文档内容进行标记。针对每个标签,该标记所标记的文档内容对应于目标网页的一个元素,用于对该元素进行加载。
在本说明书实施例中,存证服务器可以从目标网页的文档中,提取所述目标网页的标签。具体地,存证服务器可以提取所述目标网页的全部标签,也可以提取所述目标网页的部分标签。
进一步地,当存证服务器提取的是所述目标网页的部分标签时,针对存证服务器提取的每个标签,该标签具有如下性质:该标签所标记的文档内容有较大可能随着时间的推移而发生变化(因而有监测的必要)。
例如,目标网页的用于标记网站信息(如网站域名)的标签一般不会被存证服务器提取,因为网站信息通常是固定不变的。而目标网页的用于标记文章阅读数的标签一般会被存证服务器提取,因为文章阅读数通常会持续增加。
S104:从提取的标签中确定所述用户指定的标签,作为指定标签;以及获取所述用户指定的存证触发条件。
S106:针对所述指定标签进行监测,并当监测到所述指定标签所标记的文档内容满足所述存证触发条件时,对所述目标网页进行区块链存证。
在本说明书实施例中,所述用户可以预先在存证服务器上进行注册,并预先指定若干标签。于是,存证服务器在步骤S104中,可以直接从提取的标签中确定所述用户预先指定的标签,作为指定标签。需要说明的是,指定标签的数量可以大于1。
此外,存证服务器也可以将提取的标签提供给所述用户进行选择。具体地,假设用户通过浏览器访问存证服务器,存证服务器可以将展示有提取的标签的选择界面提供给所述用户,并对所述选择界面进行监测;针对所述选择界面中展示的每个标签,当监测到该标签被选择时,将该标签确定为所述用户指定的标签。
例如,在所述选择界面中,提取的各标签可以顺序排列,每个标签的旁边有相应的复选框,所述用户通过点击复选框的方式,选择相应的标签。
进一步地,所述存证服务器可以通过分析所述用户在互联网上产生的行为数据,推测出所述用户有较大概率会选择的标签。例如,所述存证服务器发现所述用户是一位小说作者,那么,推测所述用户对目标网页的用于标记文章阅读数的标签感兴趣,也就是说,所述用户有较大概率会选择用于标记文章阅读数的标签。于是,存证服务器在提供的选择界面中,可以将所述用户有较大概率会选择的标签进行突出显示(如高亮显示),以提示所述用户进行选择。
在本说明书实施例中,存证服务器还需要获取所述用户指定的存证触发条件。具体地,存证服务器可以将条件设置界面提供给所述用户,通过所述条件设置界面,接收所述用户输入的存证触发条件。
在本说明书实施例中,当指定标签的数量为1时,存证服务器可以针对所述指定标签进行监测,一旦存证触发条件满足,就触发对目标网页的区块链存证操作。
在本文中,将所述目标网页用于呈现的作品称为所述目标网页的关联作品。所述目标网页的关联作品可以有不止一个。并且,将所述目标网页的关联作品中所述用户所关注的作品,称为指定关联作品。
例如,所述目标网页是某个音乐网站的音乐列表网页,所述目标网页的关联作品为音乐作品A、音乐作品B、音乐作品C,音乐作品B的版权人发现,该音乐网站未经授权提供了音乐作品B的下载服务,那么,音乐作品B的版权人可以请求存证服务器对目标网页进行存证。所述目标网页的指定关联作品就是音乐作品B,该版权人会指定目标网页的文档中用于标记音乐作品B的标签,作为指定标签。
在版权侵权证据保全的场景下,如果所述指定标签所标记的文档内容包括所述目标网页的指定关联作品所对应的相关统计量,那么,当所述目标网页的指定关联作品所对应的相关统计量达到备选量集合中的任一备选量时,意味着所述指定标签所标记的文档内容满足所述存证触发条件。
其中,所述目标网页的文档内容是指所述目标网页所呈现的作品。所述指定关联作品对应的相关统计量包括但不限于以下:下载量、阅读量、收藏量、播放量、点赞量等。
所述备选量集合中的各备选量可以根据实际需要指定。进一步地,假设所述备选量集合中包含N个备选量,这N个备选量可以通过以下方式确定:
设所述目标网页的指定关联作品所对应的相关统计量当前为x,指定比例为y(小于1);
将x*(y+1)作为第一个备选量;
将x*(y+1) 2作为第二个备选量;
……
将x(y+1) N作为第N个备选量。
可见,通过上述方式确定备选量集合,实际上可以实现所述相关统计量每增加指定比例(如20%),就及时对目标网页进行一次区块链存证。
例如,目标网页的指定关联作品对应的相关统计量每增加20%,就会触发存证服务器对目标网页执行一次区块链存证操作。如此,版权人总是可以对侵权作品的最大相关统计量进行存证,以便尽可能要求更大数额的侵权损害赔偿,最大程度地惩罚目标网页的所有者。
版权侵权证据保全的场景下,如果所述指定标签所标记的网页相关信息为,所述目标网页的指定关联作品或所述指定关联作品对应的版权相关信息,那么,当所述目标网页的指定关联作品发生改变时,或,当所述指定关联作品对应的版权相关信息发生改变时,意味着所述指定标签所标记的文档内容满足所述存证触发条件。
其中,所述指定关联作品对应的版权相关信息,是指标识所述指定关联作品的版权状态的信息,如授权有效期信息、是否授权的信息、作品作者信息等。一旦版权相关信息发生变化,就意味着目标网页是否侵权的结论需要重新评估,此时,需要重新对目标网页进行区块链存证。
所述目标网页中的指定关联作品如果发生变化,也意味着目标网页是否还是侵权网页需要重新评估,此时,需要重新对目标网页进行区块链存证。
在版权侵权证据保全的场景下,如果所述指定标签所标记的文档内容包括所述目标 网页的指定关联作品对应的网页位置信息,那么当所述目标网页的指定关联作品对应的网页位置信息发生改变时,意味着所述指定标签所标记的文档内容足所述存证触发条件。
进一步地,所述目标网页的指定关联作品对应的网页位置信息发生改变,具体可以是:所述目标网页的指定关联作品对应的网页位置信息发生改变,并且,第一位置与所述目标网页中的参考位置的相近程度低于第二位置与所述参考位置的相近程度。其中,所述第一位置是根据改变前的所述网页位置信息确定的、所述目标网页中对应于所述指定关联作品的位置;所述第二位置是根据改变后的所述网页位置信息确定的、所述目标网页中对应于所述指定关联作品的位置。所述参考位置可以根据需要进行设定。
举例来说,假设目标网页是用于呈现某音乐网站上下载量top10的音乐作品的排行榜,那么,随着时间的推移,所述目标网页上,top10音乐作品的排名情况有可能发生改变。对于版权人而言,其关注指定关联作品(未经版权人授权)在排行榜中的名次,指定关联作品的下载量越高,排名越靠前,版权人可诉求的侵权损害赔偿越高。于是,可以将目标网页的左上角设定为参考位置,并监测指定关联作品对应的位置在目标网页中的变化。当监测到指定关联作品对应的位置发生变化,且距离参考位置更近时(意味着指定关联作品排名上升),对目标网页进行一次区块链存证。
此外,如果指定标签的数量大于1,则存证服务器可以针对每个指定标签,获取所述用户指定的对应于该指定标签的存证触发条件。存证服务器可以针对每个指定标签进行监测,一旦监测到指定数量的指定标签满足自身对应的存证触发条件,就触发对目标网页的区块链存证操作。也就是说,若存在指定数量的指定标签满足:针对所述指定数量的指定标签中的每个指定标签,该指定标签所标记的文档内容满足自身对应的存证触发条件;则触发对目标网页的区块链存证操作。
通过图1所示的方法,区块链存证方的服务器可以应版权人的请求,一方面从目标网页的文档中确定出版权人指定的标签进行监测,另一方面获取版权人指定的存证触发条件。区块链存证方的服务器当监测到版权人指定的标签所标记的文档内容满足所述存证触发条件时,就会触发一次对目标网页的区块链存证操作。如此,版权人通过指定标签与指定存证触发条件,将监测目标网页的任务交由区块链存证方的服务器执行。版权人不需要耗费精力持续关注目标网页的动态,对版权人而言更为便利。
另外,在本说明书实施例中,存证服务器还可以获取所述用户指定至少一个时间点,并针对每个时间点,当时间经过该时间点时,对所述目标网页进行区块链存证。如此, 就实现了对所述目标网页的定时存证。
需要说明的是,如果用户需要存证服务器每当经过指定周期对目标网页进行一次区块链存证,那么,上述的各时间点实际上是用户根据指定周期指定的。
此外,在本说明书实施例中,所述用户可以重新配置对目标网页的存证策略。具体地,存证服务器可以接收所述用户发送的重配置指令,并响应于所述重配置指令,重新提取所述网页地址对应的目标网页的标签,以便所述用户重新指定标签和/或重新指定存证触发条件。
还有,在本说明书实施例中,在获取所述用户指定的存证触发条件之后,还可以根据所述存证触发条件,确定监测工作量;根据所述监测工作量,确定付费金额;将付费界面提供给所述用户,以便所述用户支付所述付费金额。
其中,所述监测工作量与所述付费金额正相关。根据所述监测工作量确定付费金额的标准可以由区块链存证方根据实际需要进行设置,本说明书对此不做具体限定。
进一步地,当目标网页上存在用户关注的侵权作品时,该侵权作品就是目标网页的指定关联作品。用户不论指定目标网页的文档中的哪些标签为指定标签,事实上都是与对指定关联作品的关注需求有关。例如,所述指定标签所标记的文档内容可以是指定关联作品对应的相关统计量、版权状态信息或指定关联作品本身。实践中,一旦所述指定关联作品被从目标网页中撤下之后,也就没必要对目标网页进行监测了。对用户而言,从对目标网页中的指定标签开始监测起,直至指定关联作品被撤下,所经过的期间实际上可以认为是可证明的、指定关联作品在目标网页上存续的期间,这是比较重要的证据。
为此,在本说明书实施例中,当针对所述指定标签进行开始监测时,记录开始监测的时间;以及,当监测到所述目标网页的指定关联作品被删除时,结束监测,并记录结束监测的时间。进而,可以根据记录的开始监测的时间与结束监测的时间,生成所述目标网页对应的存续期间证据,并对所述存续期间证据进行区块链存证。
进一步地,在步骤S106中,若所述目标网页的指定关联作品为可播放作品(如视频、音频等),则对目标网页进行区块链存证,具体可以是:
对所述目标网页进行截图,得到网页截图;从所述目标网页中读取所述指定关联作品的作品存储地址,并从所述作品存储地址获取可播放作品;将所述网页截图与所述可播放作品处理成目标哈希;将所述目标哈希发布至区块链进行存证。
图2是本说明书实施例提供的一种通过文件获取对网页进行区块链存证的方法的流程示意图,包括以下步骤:
S200:访问目标网页。
本方法的执行主体也可以是存证服务器。
S202:对所述目标网页进行截图,得到网页截图;以及,读取所述目标网页关联的文件存储地址,并从所述文件存储地址获取可播放文件。
在本说明书实施例中,存证服务器在访问目标网页之后,可以一方面对目标网页进行截图,得到网页截图;另一方面,读取所述目标网页关联的文件存储地址,以便从所述文件存储地址获取可播放文件。
其中,所述目标网页关联的文件存储地址,是指所述目标网页用于播放的可播放文件的文件存储地址。一般而言,对于用于播放可播放文件的网页而言,由于可播放文件的存储大小较大,因此该网页并不包含可播放文件本身,而是仅包含可播放文件的文件存储地址。当需要播放可播放文件时,浏览器需要从该网页中解析出文件存储地址,从文件存储地址获取可播放文件并播放。
S204:将所述网页截图与所述可播放文件处理成目标哈希。
在本说明书实施例中,将数据处理成哈希,是指以数据为哈希算法的输入,进行哈希计算,得到相应的哈希值。
在步骤S204中,存证服务器可以直接对所述网页截图与所述可播放文件进行哈希计算,得到目标哈希。也可以一方面将所述网页截图处理成截图哈希,另一方面将所述可播放文件处理成文件哈希,最后,将所述截图哈希与所述文件哈希处理成目标哈希。
S206:对所述目标哈希进行区块链存证。
众所周知,数据经过哈希运算之后得到的哈希值,可以唯一标识该数据,可以视为该数据的“指纹”。该数据一旦被篡改,该数据对应的哈希值也会发生改变。因此,将所述网页截图与所述可播放文件对应的目标哈希进行区块链存证,相当于对所述目标网页、所述目标网页所用于播放的可播放文件以及所述目标网页与所述可播放文件的对应关系进行了区块链存证,可证明以下事实:
1、目标网页是真实存在且未经篡改的;
2、可播放文件是真实存在且未经篡改的;
3、目标网页是用于播放所述可播放文件的网页。
于是,通过图1所示的方法,就实现了对关联有可播放文件,却并未包含可播放文件本身的网页的区块链存证。
在本说明书实施例中,如果存证服务器不是区块链网络中的节点,那么存证服务器可以将所述目标哈希提交给区块链网络进行存证。
如果存证服务器是区块链网络中的一个区块链节点,那么,存证服务器可以基于所述目标哈希,构建目标交易,然后将所述目标交易广播给除自身之外的其他区块链节点,以使各区块链节点基于共识机制,将所述目标交易存入自身的区块链。
需要说明的是,在本说明书中所描述的交易(transaction),是指用户通过区块链的客户端创建,并需要最终发布至区块链的分布式数据库中的一笔数据。
也就是说,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向区块链发布的一笔具有业务意图的业务数据;例如,运营方可以基于实际的业务需求搭建一个联盟链,依托于联盟链部署一些与价值转移无关的其它类型的在线业务(比如,租房业务、车辆调度业务、保险理赔业务、信用服务、医疗服务等),而在这类联盟链中,交易可以是用户在联盟链中发布的一笔具有业务意图的业务消息或者业务请求。
通过图2所示方法,对于关联有可播放文件,却并未包含可播放文件本身的目标网页,区块链存证方一方面对所述目标网页进行截图,得到网页截图;另一方面读取所述目标网页关联的文件存储地址,从所述文件存储地址获取可播放文件。随后,对所述网页截图与所述可播放文件进行哈希运算,得到目标哈希,进而将所述目标哈希发布至区块链进行存证。这相当于实现了对包含可播放文件的网页的区块链存证。如此,区块链存证方的服务器不需要耗费时间对可播放文件的播放过程进行记录,提升了存证效率。
此外,实际应用中,所述目标网页可以用于播放不止一个可播放文件,这也意味着,所述目标网页关联有不止一个文件存储地址。
于是,存证服务器可以针对所述目标网页关联的每个文件存储地址,从该文件存储地址获取可播放文件,作为该文件存储地址对应的可播放文件。然后,将所述网页 截图与所述目标网页关联的各文件存储地址分别对应的可播放文件处理成目标哈希。
进一步地,有时,所述目标网页可以包含不止一个子网页链接,用户点击任一子网页链接后,可以进入该子网页链接对应的子网页,该子网页用于播放一个可播放文件。
这种情况下,存证服务器读取所述目标网页关联的不止一个文件存储地址,具体可以是针对所述目标网页中包含的每个子网页链接,访问该子网页链接,然后读取该子网页链接对应的子网页中包含的文件存储地址。
并且,由于目标网页中各子网页链接一般是按一定顺序进行排列的,因此,在上述的步骤S204中,具体可以是根据所述目标网页中各子网页链接的排列顺序,对各子网页链接分别对应的文件存储地址进行排序;根据各文件存储地址的排列顺序,各文件存储地址分别对应的可播放文件进行排序,得到可播放文件序列;将所述网页截图与所述可播放文件序列处理成目标哈希。
如此,一旦目标网页中各子网页链接的排列顺序发生变化,就会导致基于目标网页得到的目标哈希发生变化。将所述目标哈希进行区块链存证,不仅相当于将所述目标网页的内容进行了区块链存证,还相当于将所述目标网页的内容布局进行了区块链存证。
更进一步地,存证服务器将所述网页截图与所述可播放文件序列处理成目标哈希,具体可以是将所述网页截图处理成截图哈希;针对所述可播放文件序列中的每个可播放文件,将该可播放文件处理成文件哈希;根据各可播放文件的排列顺序,对各可播放文件对应的文件哈希进行排序,得到文件哈希序列;基于所述文件哈希序列,构建梅克尔树;将所述截图哈希与所述梅克尔树的根哈希处理成目标哈希。
图3是本说明书实施例提供的基于文件哈希序列构建的梅克尔树示意图。如图3所示,基于所述文件哈希序列构建的梅克尔树的根哈希可以唯一标识所述文件哈希序列,可以视为所述文件哈希序列的“指纹”。而所述文件哈希序列,实际上是所述目标网页中,各可播放文件分别对应的子网页链接的排列情况的映射。
一旦所述目标网页中某个子网页链接被更换,就需要对所述目标网页重新进行一次存证。具体地,仍然会采用上述方式,基于当前的目标网页得到新的文件哈希序列。然后,基于新的文件哈希序列重新构建梅克尔树得到新的根哈希进行存证。
需要说明的是,采用梅克尔树的方式对文件哈希序列进行存储的优势在于,当目标网页的内容变动较少时,相应的文件哈希序列的变动也会较少,此时,只需要将旧的梅克尔树中与变动相关的路径上的哈希值重新计算即可得到新的梅克尔树。
如图4所示,假设目标网页中网页子链接3被更换网页子链接8,相应的文件哈希3也就被更换为文件哈希8,于是,再重新构建梅克尔树时,只需要将旧的梅克尔树中文件哈希3-哈希6-哈希7这一路径进行更新即可(更新为文件哈希8-哈希9-哈希10)。最终,将根哈希更新为哈希10。如此,节省了存证服务器的计算资源。
基于图1所示方法,本说明书实施例还对应提供了一种通过网页监测对网页进行区块链存证的装置,如图5所示,包括:
接收模块501,接收用户发送的网页地址,并访问所述网页地址对应的目标网页;
