Cost-Effectively Searchable Blackbox Data with Unlinkability Based on Public Blockchain

Aim:

        The aim of this project is to propose a novel approach to create a cost-effective and searchable blackbox data storage system utilizing blockchain technology.

Abstract:

        A blackbox data can be used to identify the cause of an accident. And we may need to find blackbox videos recorded by the third party to accurately analyze the cause of the accident. One of the basic requirements of blackbox data is integrity, and this integrity can be provided by uploading the data to blockchains. Blackbox data plays a crucial role in accident analysis, providing insights into the causes of incidents. The need for third-party blackbox videos for accurate analysis is evident. Ensuring the integrity of blackbox data is a fundamental requirement, and leveraging blockchains for data storage can address this need. However, existing blackbox data storage systems face challenges related to cost and privacy. This situation renders the use of these platforms for uploading blackbox videos potentially expensive for users. Additionally, there is a privacy risk where sensitive information, such as driving routes, may be exposed through uploaded data. We suggest a cost-effective searchable blackbox data storage system with strong anonymity, i.e. unlinkability, using blockchains. In our scheme, the cost of registering a blackbox video is costtrn , where costtr is the cost necessary to upload a transaction to a blockchain and n is the number of uploading users at the same time.

 Existing System:

               The existing blackbox data storage systems have two big problems, cost and privacy. The transaction fees are the costs necessary to upload data to the blockchains. The transaction fees of the major public blockchain are getting higher. Therefore, if a user uses Bitcoin or Ethereum to upload its blackbox video, the costs could be very expensive. On the other hand, the private information such as driving route could be revealed from the uploaded information to the blockchain. However, existing blackbox data storage systems significant challenges, primarily centered around cost and privacy. The other problem of the simple scheme is that a user pays a lot of cost.

Disadvantage:

            Searchable blackbox storage during the video recording, we don’t use GPS to retrieve the location; instead, we retrieve the current location through a browser, which means we can’t obtain the precise location. The application will provide you with an approximate location. The simple scheme reveals some private information of the users. To upload a hash of blackbox data to a blockchain, a user must make a transaction including the hash of blackbox data. Usually, the transaction is made by signing the hash of blackbox data using the user’s private key.

Proposed System:

           Proposed a blockchain based architecture to enhance the security of a vehicle ecosystem and privacy of users. Each user has a storage that can store sensitive data such as driving information. To provide the integrity of the stored data, the hash of the data is also stored in the blockchain. We propose a searchable and unlikable blackbox data storage systems. In this system, we assume that each user who store blackbox data to the blockchain has added hash verification part for before users and client for access any datas.

Advantage:

• The paper suggests a cost-effective and searchable blackbox data storage system with strong anonymity, specifically unlinkability, using blockchains. Recognizes the importance of privacy in blackbox data.
• Introduces a searchable blackbox data storage system, suggesting an efficient way to retrieve and analyze relevant information after an accident.
• Searchable Blackbox Data with Unlinkability Based on Public Blockchain It is easy to understand the working principles of blockchain technology.
