為了使本領域技術人員更好地理解本說明書實施例中的技術方案，下面將結合本說明書實施例中的圖式，對本說明書實施例中的技術方案進行詳細地描述，顯然，所描述的實施例僅僅是本說明書的一部分實施例，而不是全部的實施例。基於本說明書中的實施例，本領域普通技術人員所獲得的所有其他實施例，都應當屬於保護的範圍。
以下結合圖式，詳細說明本說明書各實施例提供的技術方案。
圖1是本說明書實施例提供的一種透過網頁監測對網頁進行區塊鏈存證的方法的流程示意圖，包括以下步驟：
S100：接收使用者發送的網頁位址，並存取所述網頁位址對應的目標網頁。
本方法的執行主體一般是區塊鏈存證方的伺服器。在後文中，為了描述的方便，以“存證伺服器”代指“區塊鏈存證方的伺服器”。
所述區塊鏈存證方可以是提供區塊鏈存證服務的機構。所述區塊鏈存證方可以是區塊鏈網路中的節點，對外受理資料存證請求，基於資料存證請求獲取需要存證的資料，然後基於需要存證的資料構建資料存證交易並廣播，此外，還會參與區塊鏈網路中的各節點間的共識，以便將需要存證的資料寫入自身維護的區塊鏈(共用帳本)中。
所述區塊鏈存證方也可以是不是區塊鏈網路中的節點，而是負責代理受理資料存證請求，對需要存證的資料進行一定的處理(如對需要存證的網頁進行截圖並雜湊化)後，將處理結果提交給區塊鏈網路進行存證。
圖1所示的方法可以應用於版權侵權證據保全的場景，也可以應用於其他領域的證據保全的場景。下文將以版權侵權證據保全的場景為例，對本方案進行說明。本領域技術人員應當理解，在其他領域的證據保全的場景下，也可以透過圖1所示的方法流程，透過網頁監測實現對網頁的區塊鏈存證。
在版權侵權證據保全的場景下，所述使用者一般是持有作品版權的版權人。所述使用者當發現某個呈現了侵權作品的網頁(目標網頁)時，可以透過瀏覽器存取存證伺服器，並將目標網頁的網頁位址提供給存證伺服器，由存證伺服器對目標網頁進行存取。
S102：從所述目標網頁的文檔中提取標籤。
眾所周知，網頁實際上是基於超文字標記語言(Hyper Text Markup Language，HTML)文檔進行載入的，本文中所述的文檔一般是指網頁的HTML文檔。在HTML文檔中，使用若干HTML標籤對不同部分的文檔內容進行標記。針對每個標籤，該標記所標記的文檔內容對應於目標網頁的一個元素，用於對該元素進行載入。
在本說明書實施例中，存證伺服器可以從目標網頁的文檔中，提取所述目標網頁的標籤。具體地，存證伺服器可以提取所述目標網頁的全部標籤，也可以提取所述目標網頁的部分標籤。
進一步地，當存證伺服器提取的是所述目標網頁的部分標籤時，針對存證伺服器提取的每個標籤，該標籤具有如下性質：該標籤所標記的文檔內容有較大可能隨著時間的推移而發生變化(因而有監測的必要)。
例如，目標網頁的用於標記網站資訊(如網站功能變數名稱)的標籤一般不會被存證伺服器提取，因為網站資訊通常是固定不變的。而目標網頁的用於標記文章閱讀數的標籤一般會被存證伺服器提取，因為文章閱讀數通常會持續增加。
S104：從提取的標籤中判定所述使用者指定的標籤，作為指定標籤；以及獲取所述使用者指定的存證觸發條件。
S106：針對所述指定標籤進行監測，並當監測到所述指定標籤所標記的文檔內容滿足所述存證觸發條件時，對所述目標網頁進行區塊鏈存證。
在本說明書實施例中，所述使用者可以預先在存證伺服器上進行註冊，並預先指定若干標籤。於是，存證伺服器在步驟S104中，可以直接從提取的標籤中判定所述使用者預先指定的標籤，作為指定標籤。需要說明的是，指定標籤的數量可以大於1。
此外，存證伺服器也可以將提取的標籤提供給所述使用者進行選擇。具體地，假設使用者透過瀏覽器存取存證伺服器，存證伺服器可以將展示有提取的標籤的選擇介面提供給所述使用者，並對所述選擇介面進行監測；針對所述選擇介面中展示的每個標籤，當監測到該標籤被選擇時，將該標籤判定為所述使用者指定的標籤。
例如，在所述選擇介面中，提取的各標籤可以順序排列，每個標籤的旁邊有相應的核取方塊，所述使用者透過點擊核取方塊的方式，選擇相應的標籤。
進一步地，所述存證伺服器可以透過分析所述使用者在網際網路上產生的行為資料，推測出所述使用者有較大機率會選擇的標籤。例如，所述存證伺服器發現所述使用者是一位小說作者，那麼，推測所述使用者對目標網頁的用於標記文章閱讀數的標籤感興趣，也就是說，所述使用者有較大機率會選擇用於標記文章閱讀數的標籤。於是，存證伺服器在提供的選擇介面中，可以將所述使用者有較大機率會選擇的標籤進行突出顯示(如高亮顯示)，以提示所述使用者進行選擇。
在本說明書實施例中，存證伺服器還需要獲取所述使用者指定的存證觸發條件。具體地，存證伺服器可以將條件設置介面提供給所述使用者，透過所述條件設置介面，接收所述使用者輸入的存證觸發條件。
在本說明書實施例中，當指定標籤的數量為1時，存證伺服器可以針對所述指定標籤進行監測，一旦存證觸發條件滿足，就觸發對目標網頁的區塊鏈存證操作。
在本文中，將所述目標網頁用於呈現的作品稱為所述目標網頁的關聯作品。所述目標網頁的關聯作品可以有不止一個。並且，將所述目標網頁的關聯作品中所述使用者所關注的作品，稱為指定關聯作品。
例如，所述目標網頁是某個音樂網站的音樂清單網頁，所述目標網頁的關聯作品為音樂作品A、音樂作品B、音樂作品C，音樂作品B的版權人發現，該音樂網站未經授權提供了音樂作品B的下載服務，那麼，音樂作品B的版權人可以請求存證伺服器對目標網頁進行存證。所述目標網頁的指定關聯作品就是音樂作品B，該版權人會指定目標網頁的文檔中用於標記音樂作品B的標籤，作為指定標籤。
在版權侵權證據保全的場景下，如果所述指定標籤所標記的文檔內容包括所述目標網頁的指定關聯作品所對應的相關統計量，那麼，當所述目標網頁的指定關聯作品所對應的相關統計量達到備選量集合中的任一備選量時，意味著所述指定標籤所標記的文檔內容滿足所述存證觸發條件。
其中，所述目標網頁的文檔內容是指所述目標網頁所呈現的作品。所述指定關聯作品對應的相關統計量包括但不限於以下：下載量、閱讀量、收藏量、播放量、點讚量等。
所述備選量集合中的各備選量可以根據實際需要指定。進一步地，假設所述備選量集合中包含N個備選量，這N個備選量可以透過以下方式判定：
設所述目標網頁的指定關聯作品所對應的相關統計量當前為x，指定比例為y(小於1)；
將x*(y+1)作為第一個備選量；
將x*(y+1)2
作為第二個備選量；
……
將x(y+1)N
作為第N個備選量。
可見，透過上述方式判定備選量集合，實際上可以實現所述相關統計量每增加指定比例(如20%)，就及時對目標網頁進行一次區塊鏈存證。
例如，目標網頁的指定關聯作品對應的相關統計量每增加20%，就會觸發存證伺服器對目標網頁執行一次區塊鏈存證操作。如此，版權人總是可以對侵權作品的最大相關統計量進行存證，以便盡可能要求更大數額的侵權損害賠償，最大程度地懲罰目標網頁的所有者。
版權侵權證據保全的場景下，如果所述指定標籤所標記的網頁相關資訊為，所述目標網頁的指定關聯作品或所述指定關聯作品對應的版權相關資訊，那麼，當所述目標網頁的指定關聯作品發生改變時，或，當所述指定關聯作品對應的版權相關資訊發生改變時，意味著所述指定標籤所標記的文檔內容滿足所述存證觸發條件。
其中，所述指定關聯作品對應的版權相關資訊，是指標識所述指定關聯作品的版權狀態的資訊，如授權有效期資訊、是否授權的資訊、作品作者資訊等。一旦版權相關資訊發生變化，就意味著目標網頁是否侵權的結論需要重新評估，此時，需要重新對目標網頁進行區塊鏈存證。
所述目標網頁中的指定關聯作品如果發生變化，也意味著目標網頁是否還是侵權網頁需要重新評估，此時，需要重新對目標網頁進行區塊鏈存證。
在版權侵權證據保全的場景下，如果所述指定標籤所標記的文檔內容包括所述目標網頁的指定關聯作品對應的網頁位置資訊，那麼當所述目標網頁的指定關聯作品對應的網頁位置資訊發生改變時，意味著所述指定標籤所標記的文檔內容足所述存證觸發條件。
進一步地，所述目標網頁的指定關聯作品對應的網頁位置資訊發生改變，具體可以是：所述目標網頁的指定關聯作品對應的網頁位置資訊發生改變，並且，第一位置與所述目標網頁中的參考位置的相近程度低於第二位置與所述參考位置的相近程度。其中，所述第一位置是根據改變前的所述網頁位置資訊判定的、所述目標網頁中對應於所述指定關聯作品的位置；所述第二位置是根據改變後的所述網頁位置資訊判定的、所述目標網頁中對應於所述指定關聯作品的位置。所述參考位置可以根據需要進行設定。
舉例來說，假設目標網頁是用於呈現某音樂網站上下載量top10的音樂作品的排行榜，那麼，隨著時間的推移，所述目標網頁上，top10音樂作品的排名情況有可能發生改變。對於版權人而言，其關注指定關聯作品(未經版權人授權)在排行榜中的名次，指定關聯作品的下載量越高，排名越靠前，版權人可訴求的侵權損害賠償越高。於是，可以將目標網頁的左上角設定為參考位置，並監測指定關聯作品對應的位置在目標網頁中的變化。當監測到指定關聯作品對應的位置發生變化，且距離參考位置更近時(意味著指定關聯作品排名上升)，對目標網頁進行一次區塊鏈存證。
此外，如果指定標籤的數量大於1，則存證伺服器可以針對每個指定標籤，獲取所述使用者指定的對應於該指定標籤的存證觸發條件。存證伺服器可以針對每個指定標籤進行監測，一旦監測到指定數量的指定標籤滿足自身對應的存證觸發條件，就觸發對目標網頁的區塊鏈存證操作。也就是說，若存在指定數量的指定標籤滿足：針對所述指定數量的指定標籤中的每個指定標籤，該指定標籤所標記的文檔內容滿足自身對應的存證觸發條件；則觸發對目標網頁的區塊鏈存證操作。
透過圖1所示的方法，區塊鏈存證方的伺服器可以應版權人的請求，一態樣從目標網頁的文檔中判定出版權人指定的標籤進行監測，另一態樣獲取版權人指定的存證觸發條件。區塊鏈存證方的伺服器當監測到版權人指定的標籤所標記的文檔內容滿足所述存證觸發條件時，就會觸發一次對目標網頁的區塊鏈存證操作。如此，版權人透過指定標籤與指定存證觸發條件，將監測目標網頁的任務交由區塊鏈存證方的伺服器執行。版權人不需要耗費精力持續關注目標網頁的動態，對版權人而言更為便利。
另外，在本說明書實施例中，存證伺服器還可以獲取所述使用者指定至少一個時間點，並針對每個時間點，當時間經過該時間點時，對所述目標網頁進行區塊鏈存證。如此，就實現了對所述目標網頁的定時存證。
需要說明的是，如果使用者需要存證伺服器每當經過指定週期對目標網頁進行一次區塊鏈存證，那麼，上述的各時間點實際上是使用者根據指定週期指定的。
此外，在本說明書實施例中，所述使用者可以重新配置對目標網頁的存證策略。具體地，存證伺服器可以接收所述使用者發送的重配置指令，並回應於所述重配置指令，重新提取所述網頁位址對應的目標網頁的標籤，以便所述使用者重新指定標籤和/或重新指定存證觸發條件。
還有，在本說明書實施例中，在獲取所述使用者指定的存證觸發條件之後，還可以根據所述存證觸發條件，判定監測工作量；根據所述監測工作量，判定付費金額；將付費介面提供給所述使用者，以便所述使用者支付所述付費金額。
其中，所述監測工作量與所述付費金額正相關。根據所述監測工作量判定付費金額的標準可以由區塊鏈存證方根據實際需要進行設置，本說明書對此不做具體限定。
進一步地，當目標網頁上存在使用者關注的侵權作品時，該侵權作品就是目標網頁的指定關聯作品。使用者不論指定目標網頁的文檔中的哪些標籤為指定標籤，事實上都是與對指定關聯作品的關注需求有關。例如，所述指定標籤所標記的文檔內容可以是指定關聯作品對應的相關統計量、版權狀態資訊或指定關聯作品本身。實踐中，一旦所述指定關聯作品被從目標網頁中撤下之後，也就沒必要對目標網頁進行監測了。對使用者而言，從對目標網頁中的指定標籤開始監測起，直至指定關聯作品被撤下，所經過的期間實際上可以認為是可證明的、指定關聯作品在目標網頁上存續的期間，這是比較重要的證據。
為此，在本說明書實施例中，當針對所述指定標籤進行開始監測時，記錄開始監測的時間；以及，當監測到所述目標網頁的指定關聯作品被刪除時，結束監測，並記錄結束監測的時間。進而，可以根據記錄的開始監測的時間與結束監測的時間，產生所述目標網頁對應的存續期間證據，並對所述存續期間證據進行區塊鏈存證。
進一步地，在步驟S106中，若所述目標網頁的指定關聯作品為可播放作品(如視訊、音訊等)，則對目標網頁進行區塊鏈存證，具體可以是：
對所述目標網頁進行截圖，得到網頁截圖；從所述目標網頁中讀取所述指定關聯作品的作品儲存位址，並從所述作品儲存位址獲取可播放作品；將所述網頁截圖與所述可播放作品處理成目標雜湊；將所述目標雜湊發佈至區塊鏈進行存證。
圖2是本說明書實施例提供的一種透過文件獲取對網頁進行區塊鏈存證的方法的流程示意圖，包括以下步驟：
S200：存取目標網頁。
本方法的執行主體也可以是存證伺服器。
S202：對所述目標網頁進行截圖，得到網頁截圖；以及，讀取所述目標網頁關聯的文件儲存位址，並從所述文件儲存位址獲取可播放文件。
在本說明書實施例中，存證伺服器在存取目標網頁之後，可以一態樣對目標網頁進行截圖，得到網頁截圖；另一態樣，讀取所述目標網頁關聯的文件儲存位址，以便從所述文件儲存位址獲取可播放文件。
其中，所述目標網頁關聯的文件儲存位址，是指所述目標網頁用於播放的可播放文件的文件儲存位址。一般而言，對於用於播放可播放文件的網頁而言，由於可播放文件的儲存大小較大，因此該網頁並不包含可播放文件本身，而是僅包含可播放文件的文件儲存位址。當需要播放可播放文件時，瀏覽器需要從該網頁中解析出文件儲存位址，從文件儲存位址獲取可播放文件並播放。
S204：將所述網頁截圖與所述可播放文件處理成目標雜湊。
在本說明書實施例中，將資料處理成雜湊，是指以資料為雜湊演算法的輸入，進行雜湊計算，得到相應的雜湊值。
在步驟S204中，存證伺服器可以直接對所述網頁截圖與所述可播放文件進行雜湊計算，得到目標雜湊。也可以一態樣將所述網頁截圖處理成截圖雜湊，另一態樣將所述可播放文件處理成文件雜湊，最後，將所述截圖雜湊與所述文件雜湊處理成目標雜湊。
S206：對所述目標雜湊進行區塊鏈存證。
眾所周知，資料經過雜湊運算之後得到的雜湊值，可以唯一標識該資料，可以視為該資料的“指紋”。該資料一旦被篡改，該資料對應的雜湊值也會發生改變。因此，將所述網頁截圖與所述可播放文件對應的目標雜湊進行區塊鏈存證，相當於對所述目標網頁、所述目標網頁所用於播放的可播放文件以及所述目標網頁與所述可播放文件的對應關係進行了區塊鏈存證，可證明以下事實：
1、目標網頁是真實存在且未經篡改的；
2、可播放文件是真實存在且未經篡改的；
3、目標網頁是用於播放所述可播放文件的網頁。
於是，透過圖1所示的方法，就實現了對關聯有可播放文件，卻並未包含可播放文件本身的網頁的區塊鏈存證。
在本說明書實施例中，如果存證伺服器不是區塊鏈網路中的節點，那麼存證伺服器可以將所述目標雜湊提交給區塊鏈網路進行存證。
如果存證伺服器是區塊鏈網路中的一個區塊鏈節點，那麼，存證伺服器可以基於所述目標雜湊，構建目標交易，然後將所述目標交易廣播給除自身之外的其他區塊鏈節點，以使各區塊鏈節點基於共識機制，將所述目標交易存入自身的區塊鏈。
需要說明的是，在本說明書中所描述的交易(transaction)，是指使用者透過區塊鏈的使用者端建立，並需要最終發佈至區塊鏈的分散式資料庫中的一筆資料。
也就是說，區塊鏈中的交易，存在狹義的交易以及廣義的交易之分。狹義的交易是指使用者向區塊鏈發佈的一筆價值轉移；例如，在傳統的比特幣區塊鏈網路中，交易可以是使用者在區塊鏈中發起的一筆轉帳。而廣義的交易是指使用者向區塊鏈發佈的一筆具有業務意圖的業務資料；例如，運營方可以基於實際的業務需求搭建一個聯盟鏈，依託於聯盟鏈部署一些與價值轉移無關的其它類型的線上業務(比如，租房業務、車輛調度業務、保險理賠業務、信用服務、醫療服務等)，而在這類聯盟鏈中，交易可以是使用者在聯盟鏈中發佈的一筆具有業務意圖的業務消息或者業務請求。
透過圖2所示方法，對於關聯有可播放文件，卻並未包含可播放文件本身的目標網頁，區塊鏈存證方一態樣對所述目標網頁進行截圖，得到網頁截圖；另一態樣讀取所述目標網頁關聯的文件儲存位址，從所述文件儲存位址獲取可播放文件。隨後，對所述網頁截圖與所述可播放文件進行雜湊運算，得到目標雜湊，進而將所述目標雜湊發佈至區塊鏈進行存證。這相當於實現了對包含可播放文件的網頁的區塊鏈存證。如此，區塊鏈存證方的伺服器不需要耗費時間對可播放文件的播放過程進行記錄，提升了存證效率。
此外，實際應用中，所述目標網頁可以用於播放不止一個可播放文件，這也意味著，所述目標網頁關聯有不止一個文件儲存位址。
於是，存證伺服器可以針對所述目標網頁關聯的每個文件儲存位址，從該文件儲存位址獲取可播放文件，作為該文件儲存位址對應的可播放文件。然後，將所述網頁截圖與所述目標網頁關聯的各文件儲存位址分別對應的可播放文件處理成目標雜湊。
進一步地，有時，所述目標網頁可以包含不止一個子網頁連結，使用者點擊任一子網頁連結後，可以進入該子網頁連結對應的子網頁，該子網頁用於播放一個可播放文件。
這種情況下，存證伺服器讀取所述目標網頁關聯的不止一個文件儲存位址，具體可以是針對所述目標網頁中包含的每個子網頁連結，存取該子網頁連結，然後讀取該子網頁連結對應的子網頁中包含的文件儲存位址。
並且，由於目標網頁中各子網頁連結一般是按一定順序進行排列的，因此，在上述的步驟S204中，具體可以是根據所述目標網頁中各子網頁連結的排列順序，對各子網頁連結分別對應的文件儲存位址進行排序；根據各文件儲存位址的排列順序，各文件儲存位址分別對應的可播放文件進行排序，得到可播放文件序列；將所述網頁截圖與所述可播放文件序列處理成目標雜湊。
如此，一旦目標網頁中各子網頁連結的排列順序發生變化，就會導致基於目標網頁得到的目標雜湊發生變化。將所述目標雜湊進行區塊鏈存證，不僅相當於將所述目標網頁的內容進行了區塊鏈存證，還相當於將所述目標網頁的內容佈局進行了區塊鏈存證。
更進一步地，存證伺服器將所述網頁截圖與所述可播放文件序列處理成目標雜湊，具體可以是將所述網頁截圖處理成截圖雜湊；針對所述可播放文件序列中的每個可播放文件，將該可播放文件處理成文件雜湊；根據各可播放文件的排列順序，對各可播放文件對應的文件雜湊進行排序，得到文件雜湊序列；基於所述文件雜湊序列，構建梅克爾樹；將所述截圖雜湊與所述梅克爾樹的根雜湊處理成目標雜湊。
圖3是本說明書實施例提供的基於文件雜湊序列構建的梅克爾樹示意圖。如圖3所示，基於所述文件雜湊序列構建的梅克爾樹的根雜湊可以唯一標識所述文件雜湊序列，可以視為所述文件雜湊序列的“指紋”。而所述文件雜湊序列，實際上是所述目標網頁中，各可播放文件分別對應的子網頁連結的排列情況的映射。
一旦所述目標網頁中某個子網頁連結被更換，就需要對所述目標網頁重新進行一次存證。具體地，仍然會採用上述方式，基於當前的目標網頁得到新的文件雜湊序列。然後，基於新的文件雜湊序列重新構建梅克爾樹得到新的根雜湊進行存證。
需要說明的是，採用梅克爾樹的方式對文件雜湊序列進行儲存的優勢在於，當目標網頁的內容變動較少時，相應的文件雜湊序列的變動也會較少，此時，只需要將舊的梅克爾樹中與變動相關的路徑上的雜湊值重新計算即可得到新的梅克爾樹。
如圖4所示，假設目標網頁中網頁子連結3被更換網頁子連結8，相應的文件雜湊3也就被更換為文件雜湊8，於是，再重新構建梅克爾樹時，只需要將舊的梅克爾樹中文件雜湊3-雜湊6-雜湊7這一路徑進行更新即可(更新為文件雜湊8-雜湊9-雜湊10)。最終，將根雜湊更新為雜湊10。如此，節省了存證伺服器的計算資源。
基於圖1所示方法，本說明書實施例還對應提供了一種透過網頁監測對網頁進行區塊鏈存證的裝置，如圖5所示，包括：

Obviously, the described implementation Examples are only a part of the embodiments of this specification, but not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art should fall within the scope of protection. The technical solutions provided by the embodiments of this specification will be described in detail below in conjunction with the drawings. FIG. 1 is a schematic flowchart of a method for performing blockchain certificate deposit on a webpage through webpage monitoring provided by an embodiment of the present specification, including the following steps: S100: Receive a webpage address sent by a user, and access the webpage address The corresponding landing page. The execution subject of this method is generally the server of the blockchain depositor. In the following, for convenience of description, "certificate deposit server" refers to "blockchain depositor's server". The blockchain certificate depositor may be an institution that provides blockchain certificate deposit service. The blockchain depositor can be a node in the blockchain network, which accepts data deposit requests externally, obtains the data required for deposit based on the data deposit request, and then constructs the data deposit transaction based on the data required for deposit And broadcast, in addition, will also participate in the consensus among the various nodes in the blockchain network, in order to write the data that needs to be stored in the blockchain (shared ledger) that it maintains. The blockchain depositor may also be a node in the blockchain network, but is responsible for accepting the data deposit request from the agent and performing certain processing on the data that needs to be deposited (such as the webpage that needs to be deposited) (Screenshot and hashed), submit the processing results to the blockchain network for certificate storage. The method shown in FIG. 1 can be applied to the scenario of copyright infringement preservation, and can also be applied to the scenario of evidence preservation in other fields. In the following, the scenario of copyright infringement evidence preservation will be taken as an example to explain this solution. Those skilled in the art should understand that, in the scenario of evidence preservation in other fields, it is also possible to deposit certificates on the blockchain of the webpage through the method flow shown in FIG. 1 and through webpage monitoring. In the context of the preservation of copyright infringement evidence, the user is generally the copyright owner holding the copyright of the work. When the user finds a webpage (target webpage) that presents infringing works, he can access the certificate storage server through a browser, and provide the webpage address of the target webpage to the certificate storage server, which is served by the certificate storage server To access the target webpage. S102: Extract tags from the document of the target webpage. As we all know, web pages are actually loaded based on Hyper Text Markup Language (HTML) documents. The documents described in this article generally refer to HTML documents of web pages. In HTML documents, several HTML tags are used to mark different parts of the document content. For each tag, the document content marked by the tag corresponds to an element of the target webpage, and is used to load the element. In the embodiment of the present specification, the certificate storage server may extract the tag of the target webpage from the document of the target webpage. Specifically, the certificate storage server may extract all tags of the target webpage, or may extract part of tags of the target webpage. Further, when the certification server extracts some tags of the target webpage, for each tag extracted by the certification server, the tag has the following properties: the content of the document marked by the tag is more likely to Changes over time (thus monitoring is necessary). For example, the tags used to mark website information (such as website function variable names) on the landing page are generally not extracted by the registration server, because the website information is usually fixed. The tags used to mark the number of article readings of the target webpage are generally extracted by the certificate storage server, because the number of article readings usually continues to increase. S104: Determine, from the extracted labels, the label designated by the user as a designated label; and obtain the trigger condition for certificate deposit designated by the user. S106: Monitor the specified tag, and when it is detected that the content of the document marked by the specified tag satisfies the trigger condition for certificate deposit, perform blockchain certificate deposit on the target webpage. In the embodiment of the present specification, the user may register on the certificate storage server in advance, and specify a number of tags in advance. Therefore, in step S104, the certificate storage server can directly determine the label designated by the user as the designated label from the extracted labels. It should be noted that the number of specified tags can be greater than one. In addition, the certificate storage server may also provide the extracted tags to the user for selection. Specifically, assuming that the user accesses the certificate storage server through a browser, the certificate storage server may provide the user with a selection interface displaying the extracted tags, and monitor the selection interface; for the selection For each label displayed in the interface, when it is detected that the label is selected, the label is determined as the label designated by the user. For example, in the selection interface, the extracted labels may be arranged in sequence, and each label has a corresponding check box next to it. The user selects the corresponding label by clicking the check box. Further, the certificate storage server can infer the tags that the user has a greater chance to select by analyzing the behavior data generated by the user on the Internet. For example, if the certificate storage server finds that the user is a novel author, then it is presumed that the user is interested in the tag used to mark the number of article readings on the target webpage, that is, the user has A higher probability will select the label used to mark the number of articles read. Therefore, in the selection interface provided by the certificate storage server, the label that the user has a greater chance to select may be highlighted (such as highlighted) to prompt the user to make a selection. In the embodiment of the present specification, the certificate storage server also needs to obtain the certificate trigger condition specified by the user. Specifically, the certificate storage server may provide a condition setting interface to the user, and receive the certificate trigger condition input by the user through the condition setting interface. In the embodiment of the present specification, when the number of designated tags is 1, the certificate depositing server may monitor the designated tags, and once the deposit triggering condition is met, trigger the blockchain deposit operation on the target webpage. In this document, the work used for presenting the target webpage is referred to as the related work of the target webpage. There may be more than one related works of the target webpage. In addition, the work concerned by the user among the related works of the target webpage is called a designated related work. For example, the target webpage is a music list webpage of a music website, and the related works of the target webpage are music work A, music work B, music work C, and the copyright owner of music work B finds that the music website is unauthorized The download service of music piece B is provided, then, the copyright owner of the music piece B can request the certificate deposit server to deposit the certificate to the target webpage. The designated related work of the target webpage is music work B, and the copyright owner will designate the tag used to mark the music work B in the document of the target webpage as the designated label. In the context of preservation of copyright infringement evidence, if the document content marked by the designated tag includes relevant statistics corresponding to the designated related work of the target webpage, then when the relevant content of the designated related work of the target webpage When the statistical quantity reaches any candidate quantity in the candidate quantity set, it means that the content of the document marked by the specified label satisfies the trigger condition for certificate deposit. The document content of the target webpage refers to the works presented by the target webpage. The relevant statistics corresponding to the designated related works include, but are not limited to the following: downloads, readings, collections, playbacks, likes, etc. Each candidate amount in the candidate amount set may be specified according to actual needs. Further, assuming that the candidate quantity set includes N candidate quantities, the N candidate quantities can be determined in the following manner: Let the relevant statistics corresponding to the designated related works of the target webpage be currently x, specify The ratio is y (less than 1); x*(y+1) is the first candidate; x*(y+1) 2 is the second candidate; ……x(y+1) N is the Nth candidate. It can be seen that, by determining the set of candidate quantities through the above method, in fact, each time the relevant statistics increase by a specified percentage (for example, 20%), the target webpage is promptly registered with the blockchain. For example, every 20% increase in the relevant statistics corresponding to the specified related works of the target webpage will trigger the certificate deposit server to perform a blockchain certificate deposit operation on the target webpage. In this way, the copyright owner can always document the maximum relevant statistics of the infringing work in order to request as much damage compensation as possible and maximize the punishment of the owner of the target page. In the scenario where copyright infringement evidence is preserved, if the webpage-related information marked by the designated tag is, the designated related work of the target webpage or the copyright-related information corresponding to the designated related work, then, when the target webpage specifies When the related work changes, or when the copyright-related information corresponding to the specified related work changes, it means that the content of the document marked by the specified label meets the triggering condition for the certificate deposit. Wherein, the copyright-related information corresponding to the designated related work refers to information that identifies the copyright status of the designated related work, such as authorization validity period information, authorization information, and work author information. Once the copyright-related information changes, it means that the conclusion of whether the target page is infringing needs to be re-evaluated. At this time, the target page needs to be re-blockchained. If the designated related works in the target webpage change, it also means that whether the target webpage is still an infringing webpage needs to be re-evaluated. In a scenario where copyright infringement evidence is preserved, if the content of the document marked by the designated tag includes the webpage location information corresponding to the designated associated work of the target webpage, then the webpage location information corresponding to the designated associated work of the target webpage occurs When it is changed, it means that the content of the document marked by the specified tag is sufficient for the trigger condition for the deposit. Further, the position information of the webpage corresponding to the designated related work of the target webpage changes, which may specifically be: the positional information of the webpage corresponding to the specified related work of the target webpage changes, and the first position and the target webpage The similarity of the reference position of is lower than that of the second position and the reference position. Wherein, the first position is determined according to the position information of the webpage before the change, and corresponds to the position of the designated related work in the target webpage; the second position is based on the changed positional information of the webpage The determined position in the target webpage corresponding to the designated related work. The reference position can be set as required. For example, assuming that the target webpage is used to present a ranking of top ten downloaded music works on a music website, then, over time, the ranking of top10 musical works on the target web page may change. For copyright owners, they are concerned about the ranking of designated related works (unauthorized by the copyright owner) in the ranking list. The higher the download amount of the designated related works, the higher the ranking, and the higher the infringement damages that the copyright owner can claim. Therefore, the upper left corner of the target webpage can be set as the reference position, and the change of the position corresponding to the designated related work in the target webpage can be monitored. When it is detected that the position corresponding to the designated related work changes and is closer to the reference position (meaning that the ranking of the designated related work increases), a block chain certificate is deposited on the target webpage. In addition, if the number of designated tags is greater than 1, the certificate storage server may acquire, for each designated tag, the deposit triggering conditions specified by the user corresponding to the designated tag. The certificate storage server can monitor each specified tag. Once the specified number of specified tags meets the corresponding trigger conditions of the certificate deposit, the blockchain certificate deposit operation on the target webpage is triggered. That is to say, if there is a specified number of specified tags satisfying: for each specified tag in the specified number of specified tags, the document content marked by the specified tag satisfies the corresponding triggering condition for deposit proof; then the target webpage is triggered The blockchain deposit operation. Through the method shown in Figure 1, the server of the blockchain depositor can, at the request of the copyright owner, determine the tags specified by the copyright owner from the document of the target web page for monitoring, and acquire the copyright owner in another aspect. The specified trigger condition for deposit. When the server of the blockchain certificate depositor detects that the content of the document marked by the tag specified by the copyright owner meets the trigger condition of certificate deposit, it will trigger a blockchain certificate deposit operation on the target webpage. In this way, the copyright owner assigns the task of monitoring the target webpage to the server of the blockchain depositor through the specified tag and the specified trigger condition of the certificate deposit. The copyright owner does not need to spend energy to continuously pay attention to the dynamics of the target page, which is more convenient for the copyright owner. In addition, in the embodiment of the present specification, the certificate storage server may also acquire the user-specified at least one time point, and for each time point, when the time passes the time point, perform a blockchain on the target webpage Deposit certificate. In this way, timed deposit of the target webpage is achieved. It should be noted that if the user needs the certificate storage server to perform block chain certificate registration on the target webpage after a specified period, then the above points in time are actually specified by the user according to the specified period. In addition, in the embodiment of the present specification, the user may reconfigure the certificate storage strategy for the target webpage. Specifically, the certificate storage server may receive the reconfiguration instruction sent by the user, and in response to the reconfiguration instruction, re-extract the label of the target webpage corresponding to the webpage address, so that the user can reassign the label And/or re-specify the trigger conditions for deposit. In addition, in the embodiment of the present specification, after acquiring the trigger condition for certificate deposit designated by the user, the monitoring workload may be determined according to the trigger condition for certificate deposit; the payment amount may be determined according to the monitoring workload; A payment interface is provided to the user so that the user can pay the payment amount. Among them, the monitoring workload is positively related to the payment amount. The standard for determining the payment amount based on the monitoring workload can be set by the blockchain depositor according to actual needs, which is not specifically limited in this specification. Further, when there is an infringing work that the user pays attention to on the target webpage, the infringing work is the designated related work of the target webpage. Regardless of which tags in the document of the designated target web page are designated tags by the user, in fact, they are all related to the need to pay attention to the designated related works. For example, the document content marked by the specified tag may be related statistics corresponding to the specified related work, copyright status information, or the specified related work itself. In practice, once the designated related work is removed from the target webpage, there is no need to monitor the target webpage. For the user, from the time when the designated tag in the target webpage is monitored until the designated related work is removed, the period elapsed can actually be regarded as a provable period during which the designated related work exists on the target webpage. This is more important evidence. For this reason, in the embodiment of the present specification, when the monitoring is started for the designated tag, the time when the monitoring starts is recorded; and, when the designated related work monitored by the target webpage is deleted, the monitoring is ended, and the recording ends Monitoring time. Furthermore, according to the recorded time of starting monitoring and the time of ending monitoring, the evidence of the duration corresponding to the target webpage can be generated, and the blockchain evidence can be stored for the evidence of the duration. Further, in step S106, if the designated related work of the target webpage is a playable work (such as video, audio, etc.), then block chain certification is performed on the target webpage, which may specifically be: Take a screenshot to get a screenshot of the webpage; read the work storage address of the specified associated work from the target webpage, and obtain the playable work from the work storage address; process the webpage screenshot and the playable work To form a target hash; publish the target hash to the blockchain for certificate storage. FIG. 2 is a schematic flowchart of a method for obtaining a webpage for blockchain certificate deposit through file acquisition provided by an embodiment of the present specification, including the following steps: S200: access to a target webpage. The execution subject of this method may also be a certificate storage server. S202: Take a screenshot of the target webpage to obtain a screenshot of the webpage; and read the file storage address associated with the target webpage and obtain a playable file from the file storage address. In the embodiment of the present specification, after accessing the target webpage, the certificate storage server may take a screenshot of the target webpage to obtain a screenshot of the webpage; in another aspect, read the file storage address associated with the target webpage, In order to obtain playable files from the file storage address. Wherein, the file storage address associated with the target webpage refers to the file storage address of the playable file used for playing by the target webpage. Generally speaking, for a webpage used to play a playable file, since the playable file has a larger storage size, the webpage does not include the playable file itself, but only includes the file storage address of the playable file. When the playable file needs to be played, the browser needs to parse out the file storage address from the webpage, obtain the playable file from the file storage address and play it. S204: Process the webpage screenshot and the playable file into a target hash. In the embodiment of the present specification, processing data into a hash means that the data is used as an input of a hash algorithm to perform a hash calculation to obtain a corresponding hash value. In step S204, the certificate storage server may directly perform a hash calculation on the webpage screenshot and the playable file to obtain a target hash. Alternatively, the webpage screenshot may be processed into a screenshot hash, in another aspect, the playable file may be processed into a file hash, and finally, the screenshot hash and the file hash may be processed into a target hash. S206: Perform blockchain certificate storage on the target hash. As we all know, the hash value obtained after the data is hashed can uniquely identify the data and can be regarded as the "fingerprint" of the data. Once the data has been tampered with, the hash value corresponding to the data will also change. Therefore, performing block chain certification on the target hash corresponding to the screenshot of the webpage and the playable file is equivalent to the target webpage, the playable file used for playback by the target webpage, and the target webpage and all The corresponding relationship between the playable files is verified by the blockchain, which can prove the following facts: 1. The target webpage is real and has not been tampered with; 2. The playable file is real and has not been tampered with; 3. The target The webpage is a webpage for playing the playable file. Therefore, through the method shown in FIG. 1, the blockchain certificate for the web page associated with the playable file but not including the playable file itself is realized. In the embodiment of the present specification, if the certificate storage server is not a node in the blockchain network, the certificate storage server may submit the target hash to the blockchain network for certificate storage. If the deposit server is a blockchain node in the blockchain network, then the deposit server can build a target transaction based on the target hash, and then broadcast the target transaction to other than itself Block chain nodes, so that each block chain node stores the target transaction into its own block chain based on the consensus mechanism. It should be noted that the transaction described in this specification refers to a piece of data created by the user through the user end of the blockchain and needs to be finally released to the distributed database of the blockchain. That is to say, there are narrow transactions and broad transactions in the transactions in the blockchain. A narrowly defined transaction refers to a value transfer issued by the user to the blockchain; for example, in the traditional Bitcoin blockchain network, the transaction can be a transfer initiated by the user in the blockchain. The generalized transaction refers to a piece of business data released by the user to the blockchain with business intent; for example, the operator can build an alliance chain based on actual business needs, relying on the alliance chain to deploy some other types that are not related to value transfer Online business (for example, rental business, vehicle scheduling business, insurance claims business, credit service, medical service, etc.), and in this type of alliance chain, the transaction can be a business with business intent issued by the user in the alliance chain Message or business request. Through the method shown in FIG. 2, for a target webpage that is associated with a playable file but does not include the playable file itself, the blockchain depositor takes a screenshot of the target webpage to obtain a screenshot of the webpage; another state In this way, the file storage address associated with the target web page is read, and the playable file is obtained from the file storage address. Subsequently, a hash operation is performed on the screenshot of the web page and the playable file to obtain a target hash, and then the target hash is published to the blockchain for certificate storage. This is equivalent to realizing the blockchain certificate for the webpage containing the playable file. In this way, the server of the blockchain depositor does not need to spend time recording the playback process of playable files, which improves the efficiency of deposit certification. In addition, in actual applications, the target webpage can be used to play more than one playable file, which also means that there is more than one file storage address associated with the target webpage. Therefore, the certificate storage server may store an address for each file associated with the target webpage, and obtain a playable file from the file storage address as a playable file corresponding to the file storage address. Then, the playable files corresponding to the file storage addresses of the webpage screenshot and the target webpage respectively are processed into a target hash. Further, sometimes, the target webpage may include more than one subpage link. After a user clicks on any subpage link, the user may enter the subpage corresponding to the subpage link, and the subpage is used to play a playable file. In this case, the certificate storage server reads more than one file storage address associated with the target webpage, which may specifically be for each subpage link included in the target webpage, access the subpage link, and then read The subpage links to the file storage address contained in the corresponding subpage. In addition, since the sub-page links in the target web page are generally arranged in a certain order, in the above step S204, the sub-page links may be specifically linked according to the arrangement order of the sub-page links in the target web page Sort the corresponding file storage addresses respectively; sort the playable files corresponding to each file storage address according to the arrangement order of the file storage addresses to obtain a playable file sequence; compare the webpage screenshot with the playable The file sequence is processed into a target hash. In this way, once the arrangement order of the links of the subpages in the target webpage changes, the target hash based on the target webpage will change. Blockchain certification of the target hash is not only equivalent to blockchain certification of the content of the target webpage, but also blockchain certification of the content layout of the target webpage. Further, the certificate storage server processes the webpage screenshot and the playable file sequence into a target hash, which may specifically be processing the webpage screenshot into a screenshot hash; for each of the playable file sequences Play the file and process the playable file into a file hash; sort the file hash corresponding to each playable file according to the order of the playable files to obtain a file hash sequence; based on the file hash sequence, construct a Merkle tree ; Processing the screenshot hash and the root hash of the Merkel tree into a target hash. FIG. 3 is a schematic diagram of a Merkel tree constructed based on a file hash sequence provided by an embodiment of this specification. As shown in FIG. 3, the root hash of the Merkel tree constructed based on the file hash sequence can uniquely identify the file hash sequence, and can be regarded as a "fingerprint" of the file hash sequence. The file hash sequence is actually a mapping of the arrangement of the links of the subpages corresponding to the playable files in the target webpage. Once a link to a subpage in the target webpage is replaced, the target webpage needs to be registered again. Specifically, the above method will still be used to obtain a new file hash sequence based on the current target webpage. Then, the Merkel tree is reconstructed based on the new file hash sequence to obtain a new root hash for verification. It should be noted that the advantage of using Merkel tree to store the file hash sequence is that when the content of the target web page changes less, the corresponding file hash sequence will also change less. At this time, only the old A new Merkel tree can be obtained by recalculating the hash value on the path related to the change in the Merkel tree of. As shown in FIG. 4, suppose that the sub-link 3 of the target web page is replaced by the sub-link 8 of the web page, and the corresponding file hash 3 is also replaced by the file hash 8. Therefore, when rebuilding the Merkle tree, only the old The file hash 3-hash 6-hash 7 path in the Merkel tree can be updated (updated to file hash 8-hash 9-hash 10). Finally, the root hash is updated to hash 10. In this way, the computing resources of the certificate storage server are saved. Based on the method shown in FIG. 1, the embodiment of the present specification also correspondingly provides a device for depositing blockchain certificates on a webpage through webpage monitoring. As shown in FIG. 5, it includes: a receiving module 501 that receives webpage bits sent by users Address, and access the target webpage corresponding to the webpage address; extraction module 502, extract tags from the document of the target webpage; determination acquisition module 503, determine the tags specified by the user from the extracted tags As a designated tag; and to obtain the trigger condition for certificate deposit specified by the user; a monitoring and deposit module 504, which monitors the specified tag and detects that the document content marked by the specified tag satisfies the deposit When the card triggers the condition, a blockchain certificate is stored on the target webpage. The determination acquisition module 503 provides the selected interface with the extracted label to the user and monitors the selected interface; for each label displayed in the selected interface, when the label is detected When selected, the tag is determined as the tag specified by the user. The judgment acquisition module 503 provides a condition setting interface to the user; through the condition setting interface, receives the certificate deposit triggering condition input by the user. The number of designated tags is greater than 1; the determination acquisition module 503 acquires, for each designated tag, a trigger condition for deposit registration corresponding to the designated tag specified by the user. The content of the document marked by the specified tag satisfies the triggering condition of certificate deposit, which specifically includes: there is a specified number of specified tags satisfying: for each specified tag in the specified number of specified tags, the document marked by the specified tag The content satisfies the trigger condition for certificate deposit corresponding to the specified tag.

The content of the document marked by the specified tag includes: webpage position information corresponding to the specified associated work of the target webpage; the content of the document marked by the specified tag satisfies the triggering condition of the certificate deposit, and specifically includes: The location information of the webpage corresponding to the designated related works has changed. The position information of the webpage corresponding to the designated related work of the target webpage changes, specifically including: the positional information of the webpage corresponding to the specified related work of the target webpage changes, and the first position is different from the reference position in the target webpage The degree of similarity is lower than the degree of similarity between the second position and the reference position; wherein, the first position is determined based on the webpage position information before the change, and the position on the target webpage corresponding to the designated related work The second position is determined according to the changed position information of the web page, and corresponds to the position of the designated related work in the target web page. The device further includes: a charging module 505, after acquiring the trigger condition for certificate deposit designated by the user, determining the monitoring workload according to the trigger condition for certificate deposit; determining the payment amount based on the monitoring workload; The monitoring workload is positively related to the payment amount; a payment interface is provided to the user so that the user can pay the payment amount. The monitoring certificate storage module 504, if the designated related work of the target webpage is a playable work, then take a screenshot of the target webpage to obtain a screenshot of the webpage; read the specific associated work from the target webpage Work storage address, and obtain playable work from the work storage address; process the webpage screenshot and the playable work into a target hash; publish the target hash to the blockchain for certificate storage. The device further includes: an evidence generation module 506 during access, recording the time when the specified tag is started to be monitored; and, when the designated related work monitored by the target web page is deleted, the end Monitor and record the time when the monitoring ends; according to the recorded time when the monitoring starts and the time when the monitoring ends, generate the evidence of the duration corresponding to the target webpage, and perform block chain certification on the evidence of the duration.
