Abstract
本創作係有關於一種分散式車輛行駛歷程記錄系統：利用一汽車之一車上診斷系統將該汽車之一車輛行駛資料上傳至一區塊鏈資料庫。該車輛行駛資料上傳至該區塊鏈資料庫時，進行一資料驗證程序，包括里程驗證程序及數位簽章程序。當該車輛行駛資料通過該資料驗證程序時，該區塊鏈資料庫接收並儲存該車輛行駛資料；當該車輛行駛資料沒有通過該資料驗證程序時，該區塊鏈資料庫拒絕儲存該車輛行駛資料。藉此確保上傳至區塊鏈資料庫的車輛行駛資料的正確性。 This creation is about a decentralized vehicle driving history recording system: using a car-by-vehicle diagnostic system to upload the driving data of one car to a blockchain database. When the vehicle driving data is uploaded to the blockchain database, a data verification procedure is carried out, including a mileage verification procedure and a digital signature procedure. When the vehicle driving data passes the data verification procedure, the blockchain database receives and stores the vehicle driving data; when the vehicle driving data fails the data verification procedure, the blockchain database refuses to store the vehicle driving data. This ensures the correctness of the vehicle driving data uploaded to the blockchain database.
Description
本創作係有關於一種分散式車輛行駛歷程記錄系統，特別是指利用區塊鏈資料庫儲存車輛行駛資料的創作，且車輛行駛資料上傳至區塊鏈資料庫時，需執行資料驗證程序，以確保車輛行駛資料的正確性。 This creation is about a decentralized vehicle driving history recording system, especially the creation of using the blockchain database to store vehicle driving data, and when the vehicle driving data is uploaded to the blockchain database, data verification procedures are required to be executed. Ensure the correctness of the vehicle driving data.
車輛行駛資料為車輛保養、車輛銷售時的重要資料，目前車輛行駛歷程記錄之方法有里程表、行車紀錄器等。而不論是里程表或是行車紀錄器，都存在有被竄改或是被偽造的風險。 Vehicle driving data are important data for vehicle maintenance and vehicle sales. At present, the methods for recording vehicle driving history include odometer and driving recorder. Regardless of whether it is an odometer or a driving recorder, there is a risk of being tampered with or forged.
其中，區塊鏈(Blockchain)是藉由密碼學串接並保護內容的串連文字記錄的一種演算法，區塊鏈中每一個區塊包含了前一個區塊的加密雜湊、相應時間戳記以及交易資料，且區塊鏈數據節點由所有節點的電腦共同維護，每個參與節點的用戶都能擁有一份完整的區塊鏈資料庫內容，由於所有區塊鏈資料庫內容是透過各個節點共同維護，所以無需集中控制與維護而達成去中心化並實現去中心化之優點，這樣的設計使得區塊內容具有難以篡改的特性。因此目前區塊鏈已被廣泛應用在加密貨幣如比特幣、以太幣與萊特幣等。 Among them, the Blockchain is an algorithm that uses cryptography to concatenate and protect the concatenated text records of the content. Each block in the block chain contains the encrypted hash of the previous block, the corresponding time stamp, and Transaction data, and the blockchain data nodes are jointly maintained by the computers of all nodes. Each user participating in the node can have a complete block chain database content, because all the block chain database content is shared by each node Maintenance, so there is no need to centralize control and maintenance to achieve decentralization and achieve the advantages of decentralization. This design makes the block content difficult to tamper with. Therefore, blockchain has been widely used in cryptocurrencies such as Bitcoin, Ethereum and Litecoin.
而藉由區塊鏈資訊難以篡改的特性，中華民國發明專利第I684948號「分散式車險評估系統及其方法」、中華民國發明專利第202013218號「非圖像判斷之行車事件紀錄方法及系統」，以及中華民國發明專利第202004706號「車輛資訊監控系統及其方法」等相關前案，皆提出將車輛行駛資 料以區塊鏈資料庫進行儲存，而作為車輛保險、車輛內/外部行車資訊儲存、車輛維修等相關應用。 Due to the fact that blockchain information is difficult to tamper with, the Republic of China Invention Patent No. I684948 "Distributed Auto Insurance Evaluation System and Method", and the Republic of China Invention Patent No. 202013218 "Non-Image Judgment Method and System for Recording Driving Events" , And the Republic of China Invention Patent No. 202004706 “Vehicle Information Monitoring System and Method The materials are stored in a blockchain database and used for related applications such as vehicle insurance, vehicle internal/external driving information storage, vehicle maintenance, etc.
但是區塊鏈資料庫雖然可防止資料被篡改，卻無法避免假的資訊進入區塊鏈資料庫中，例如在車輛行駛里程紀錄進入區塊鏈資料庫之前，先對車輛行駛里程紀錄調整(例如對二手車調降里程紀錄以利於販售)，因而仍然無法完全避免獲得不正確的車輛行駛資料。 However, although the blockchain database can prevent data from being tampered with, it cannot prevent false information from entering the blockchain database. For example, before the vehicle mileage record enters the blockchain database, adjust the vehicle mileage record (e.g. Reduce the mileage records of used cars to facilitate sales), so it is still impossible to completely avoid obtaining incorrect vehicle driving information.
為了確保上傳至區塊鏈資料庫的車輛行駛資料是正確的，本創作提出一種分散式車輛行駛歷程記錄系統，包括有：一汽車，有一車上診斷系統。一區塊鏈資料庫，透過網際網路連接該汽車之車上診斷系統。該車上診斷系統將該汽車之一車輛行駛資料上傳至該區塊鏈資料庫，且該車輛行駛資料於上傳時進行一資料驗證程序；通過該資料驗證程序時，該區塊鏈資料庫接收並儲存該車輛行駛資料；沒有通過該資料驗證程序時，該區塊鏈資料庫拒絕儲存該車輛行駛資料。 In order to ensure that the vehicle driving data uploaded to the blockchain database is correct, this creation proposes a distributed vehicle driving history recording system, including: a car and an on-board diagnostic system. A blockchain database is connected to the car's on-board diagnostic system via the Internet. The on-vehicle diagnostic system uploads the vehicle driving data of one of the cars to the blockchain database, and the vehicle driving data undergoes a data verification process when uploading; when the data verification process is passed, the blockchain database receives And store the vehicle driving data; if the data verification procedure is not passed, the blockchain database refuses to store the vehicle driving data.
進一步，該資料驗證程序包括一里程驗證程序，該里程驗證程序係該區塊鏈資料庫儲存有一上一次行駛總里程，該車輛行駛資料包括有一本此行駛總里程，當該本此行駛總里程低於該上一次行駛總里程時，該區塊鏈資料庫判別該車輛行駛資料沒有通過該資料驗證程序。 Further, the data verification program includes a mileage verification program. The mileage verification program stores a total mileage of the last trip in the blockchain database. The vehicle driving data includes a book of the total mileage traveled. When the total mileage is lower than the last time, the blockchain database judges that the vehicle driving data has not passed the data verification procedure.
進一步，該資料驗證程序包括一數位簽章程序，該數位簽章程序係該車上診斷系統將一數位簽章對象以一私鑰進行加密，而該區塊鏈資料庫以相對應之一公鑰進行解密，以完成數位簽章，而無法完成數位簽章時，該區塊鏈資料庫判別該車輛行駛資料沒有通過該資料驗證程序。更進一步，該數位簽 章對象係該汽車之車牌號碼，該私鑰係該車上診斷系統之一資料解譯器序號，該公鑰係該汽車之車輛識別碼。 Furthermore, the data verification procedure includes a digital signature procedure. The digital signature procedure is that the on-board diagnostic system encrypts a digital signature object with a private key, and the blockchain database uses a corresponding public key. The key is decrypted to complete the digital signature, and when the digital signature cannot be completed, the blockchain database determines that the vehicle driving data has not passed the data verification procedure. Furthermore, the digital sign The chapter object is the license plate number of the car, the private key is the serial number of a data interpreter of the on-board diagnostic system, and the public key is the vehicle identification code of the car.
根據上述技術特徵可達成以下功效： According to the above technical features, the following effects can be achieved:
該車輛行駛資料上傳至該區塊鏈資料庫時，必須通過該資料驗證程序，包括里程驗證程序及數位簽章程序，當該車輛行駛資料沒有通過該資料驗證程序時，該區塊鏈資料庫拒絕儲存該車輛行駛資料，藉此可確保上傳至該區塊鏈資料庫的車輛行駛資料的正確性。 When the vehicle driving data is uploaded to the blockchain database, it must pass the data verification process, including the mileage verification process and the digital signature process. When the vehicle driving data does not pass the data verification process, the blockchain database Refuse to store the vehicle driving data, so as to ensure the correctness of the vehicle driving data uploaded to the blockchain database.
