以下本發明茲以第一實施例之具有可追溯驗證機制的非集中化電子交易紀錄系統1進行範例說明，惟第二實施例之具有可追溯驗證機制的非集中化電子交易紀錄方法亦可達到相同或相似之技術功效，特以說明之。 The following invention is exemplified by the decentralized electronic transaction record system 1 having the traceability verification mechanism of the first embodiment, but the decentralized electronic transaction record method with the traceability verification mechanism of the second embodiment can also be achieved. The same or similar technical effects, specifically to illustrate.
於一實施範例中，本案具有可追溯驗證機制的非集中化電子交易紀錄系統1係運行於伺服器，並利用雜湊函數串接為基礎作為銀行帳戶的各種金融交易記錄的區塊鏈，以達到交易紀錄的唯一性與防止紀錄遭竄改困難度為目的。 In an embodiment, the decentralized electronic transaction record system 1 with traceability verification mechanism runs on the server and uses the hash function to be cascaded as a blockchain of various financial transaction records of the bank account to achieve The uniqueness of the transaction record is aimed at preventing the record from being falsified.
前述系統產生器11(運算雜湊值及產生電子檔案)在接收銀行端2傳來的交易資料時①，會將儲存模組12中前一筆雜湊值與最新之交易資料作雜湊值後，組成新「區塊」傳送至用戶端3顯示③，並且將此計算出的雜湊值備存回儲存模組12取代前一筆值②，換句話說每一個「區塊」的組成，都會包含最新一筆交易訊息與上一個交易紀錄雜湊值，因此每一個區雜湊塊的生成，都重新確認了歷史上所有的區塊(僅有一條鍊上面能夠創造經過雜湊後有效的下一個區塊)，因此不容易被竄改。儲存模組12用以儲存最新的一筆雜湊交易紀錄值為辨識資料。 The system generator 11 (operating the hash value and generating the electronic file), when receiving the transaction data sent from the bank terminal 1, will make a hash value of the previous hash value in the storage module 12 and the latest transaction data to form a new one. The "block" is transmitted to the client 3 display 3, and the calculated hash value is stored back to the storage module 12 to replace the previous value 2, in other words, the composition of each "block" will contain the latest transaction. The message is hashed with the previous transaction record, so the generation of each region's hash block reconfirms all the blocks in history (only one chain can create the next block that is valid after hashing), so it is not easy Was tampered with. The storage module 12 is configured to store the latest hash transaction record value as identification data.
當用戶端3傳送儲存資料之需求時④，產生器11將回傳之所有交易明細中最後一筆交易紀錄作雜湊值後，傳至驗證模組13作比對，驗證與儲存模組12裡的雜湊值與是否相等⑤。當符合時，將此交易紀錄值分別取出雜湊與交易資料，保留此雜湊值於儲存模組12中。若還有上一筆交易紀錄時，將繼續驗證交易資料，取出上一筆交易紀錄作雜湊值，驗證是否與儲存模組12中雜湊值相等，一筆一筆回推交易紀錄的雜湊值是否屬 實，確認交易資料沒有被竄改。驗證無誤後將其所有交易明細傳送到產生器11⑥，產生電子檔案傳至用戶端3備存⑦，達到資料的隱私與傳遞安全的目的。 When the client 3 transmits the demand for storing data, the generator 11 passes the last transaction record in all the transaction details of the returned message as a hash value, and then passes it to the verification module 13 for comparison, and the verification and storage module 12 The hash value is equal to 5. When the match is made, the transaction record value is separately extracted from the hash and the transaction data, and the hash value is retained in the storage module 12. If there is a previous transaction record, it will continue to verify the transaction data, take the previous transaction record as a hash value, verify whether it is equal to the hash value in the storage module 12, and whether the hash value of a round-back transaction record belongs to In fact, it is confirmed that the transaction information has not been tampered with. After the verification is correct, all the transaction details are transmitted to the generator 116, and the electronic file is transmitted to the client 3 for storage 7, thereby achieving the purpose of data privacy and transmission security.
請參閱圖2，其為顯示用戶端3查詢交易紀錄之流程圖。圖中本方法接收銀行端2傳來的一筆交易資料S101，檢查儲存模組12中是否存在前一筆的雜湊值(Hpre)S102，若不成立，此筆交易紀錄為第一筆資料，伺服器將此筆資料作雜湊值儲存於儲存模組12後，傳給用戶端3顯示此筆交易紀錄S104。若儲存模組12中已存在Hpre值，產生器11則將Hpre串接此筆交易紀錄，組成新的區塊作雜湊值(Hpre+1)儲存於儲存模組12中S103。 Please refer to FIG. 2, which is a flow chart showing the client 3 querying the transaction record. In the figure, the method receives a transaction data S101 sent from the bank terminal 2, and checks whether there is a previous hash value (Hpre) S102 in the storage module 12. If not, the transaction record is the first data, and the server will The data is stored in the storage module 12 as a hash value, and is transmitted to the client terminal 3 to display the transaction record S104. If the Hpre value already exists in the storage module 12, the generator 11 concatenates the Hpre in the transaction record to form a new block as a hash value (Hpre+1) and stores it in the storage module 12 in S103.
請參閱圖3，其為用戶端3儲存交易之流程圖。其步驟說明如下： Please refer to FIG. 3, which is a flow chart of the client 3 storing the transaction. The steps are as follows:
S201：當用戶端3欲傳送交易紀錄儲存需求時，用戶端3會回傳所有交易紀錄。 S201: When the client 3 wants to transmit the transaction record storage requirement, the client terminal 3 returns all transaction records.
S202：產生器11將傳回之最後一筆交易紀錄作雜湊值後，比對儲存模組12中的雜湊值，驗證其是否相同？若為相同則執行S203；若不同則執行S206。 S202: The generator 11 compares the last transaction record returned as a hash value, and compares the hash values in the storage module 12 to verify whether they are the same. If it is the same, S203 is executed; if it is different, S206 is executed.
S203：將此交易紀錄值分別取出雜湊值與交易資料，並保留此雜湊值於儲存模組中。 S203: The transaction record value is respectively taken out of the hash value and the transaction data, and the hash value is retained in the storage module.
S204：判斷是否還有上一筆交易紀錄？若有則執行S207；若無則執行S205。 S204: Is there a previous transaction record? If yes, execute S207; if not, execute S205.
S205：則將所有交易紀錄轉為電子檔案，並將檔案回傳給用戶端3。 S205: All transaction records are converted into electronic files, and the files are transmitted back to the client 3.
S206：回傳錯誤資訊給用戶端3。 S206: Return error information to the client terminal 3.
S207：伺服器將取出每筆交紀錄之雜湊值，驗證每筆交紀錄之雜湊值與此 筆資料串接上一筆雜湊值所產生的雜湊值是否相等？若有則執行S203；若無則執行S206。 S207: The server will take out the hash value of each record and verify the hash value of each record. Is the hash value generated by the string data connected to a hash value equal? If yes, execute S203; if not, execute S206.
本案藉由每筆交易資料與上一筆交易紀錄產生之雜湊值作新的雜湊值，繼而串接每筆金融交易記錄，形成緊密關聯的區塊鏈，確保交易明細之連續性與完整性。 In this case, the new hash value is generated by the hash value generated by each transaction data and the previous transaction record, and then each financial transaction record is concatenated to form a closely related blockchain to ensure the continuity and integrity of the transaction details.
請參閱圖4，其為交易資料進行雜湊配置之示意圖，當用戶端3傳送查詢交易紀錄請求給伺服器時，伺服器經雜湊值運算後將此筆交易紀錄傳回給用戶端3顯示、用戶端3此時傳送儲存交易紀錄要求並將所有交易明細給伺服器，伺服器驗證資料無竄改之嫌疑後，轉為電子檔案傳回用戶端3留存。 Please refer to FIG. 4 , which is a schematic diagram of hash configuration of transaction data. When the client 3 transmits a request for querying a transaction record to the server, the server transmits the transaction record back to the client 3 for display and user after the hash value operation. At this time, terminal 3 transmits and stores the transaction record request and all the transaction details are sent to the server. After the server verifies that the data is not falsified, it is transferred to the electronic file and returned to the client terminal 3 for retention.
進一步說明之，伺服器在接收銀行端2傳來的交易資料，檢查儲存模組12中是否存在前一筆的雜湊值(Hpre)，若存在，伺服器中之產生器11則將Hpre串接其後銀行端2傳來的第一筆交易資料，組成新的區塊作雜湊值(Hpre+1)儲存於儲存模組12中並將此筆交易紀錄傳送給用戶端3顯示；若儲存模組12中無雜湊值，其第一筆交易資料直接作雜湊值後儲存並傳送給用戶端3顯示。 Further, the server receives the transaction data sent from the bank terminal 2, and checks whether there is a previous hash value (Hpre) in the storage module 12. If it exists, the generator 11 in the server connects the Hpre in series. The first transaction data sent from the bank 2 is formed into a new block for hash value (Hpre+1) stored in the storage module 12 and transmitted to the client 3 for display; if the storage module There is no hash value in 12, and the first transaction data is directly stored as a hash value and transmitted to the client 3 for display.
若含多筆交易資料，則重複(1)動作，直到全部資料更新完成。使用端傳送儲存要求給伺服器，伺服器將驗證所有傳來之交易明細資料，經確認無誤後，產生器11轉換成電子檔案，回傳至用戶端3，提供用戶端3備存。 If there are multiple transaction data, repeat (1) action until all data updates are completed. The server transmits the storage request to the server, and the server verifies all the transaction details. After confirmation, the generator 11 converts the file into an electronic file and transmits it back to the client 3 to provide the client 3 for storage.
上列詳細說明係針對本發明之一可行實施例之具體說明，惟該實施例並非用以限制本發明之專利範圍，凡未脫離本發明技藝精神所為 之等效實施或變更，均應包含於本案之專利範圍中。 The detailed description above is a detailed description of one of the possible embodiments of the present invention, which is not intended to limit the scope of the invention, which is not Equivalent implementations or changes shall be included in the scope of the patent in this case.
