BLOCKCHAIN-BASED SECURITY MODEL FOR SECURE DATA TRANSACTIONS
The frequency of online transaction between businesses and individuals is increasing every day, when it includes banking, data sharing and transaction record keeping. Many institutions today experience severe security issues such as ongoing data breaches and unauthorized access or modifications to their transaction records. These security issues show that there is very little to no secure and dependable way to manage digital transactions. A majority of people believe that blockchain technology can solve these issues because of its distinguishing features of being decentralized, allowing for the use of cryptographic techniques to secure data and providing a transparent public process for recording transactions.
This research proposes a new method for providing the security needed to conduct data transactions in a more trustworthy and efficient manner using blockchain technology. The proposed framework will provide additional integrity, transparency, reliability, and security to digital transaction systems by creating an alternative digital transaction system through blockchain network data storage and transaction validation without having a central authority. In addition to having the additional integrity, transparency, reliability and security provided to digital transaction systems, all transactions are also secured using cryptography and recorded in a series of blocks with secure links between blocks.
The proposed digital transaction model will ensure the integrity of individual transactions by supplying the means to prevent unauthorized modification and maintain the consistency of data generated by all transactions throughout the entire blockchain network. Therefore, the model will provide a secure and transparent platform for conducting digital transactions through the use of cryptographic hashes and consensus mechanisms. This research concludes that through the application of the proposed digital transaction model digital transactions will have a higher level of integrity and security through the implementation of integrated blockchain transactions.
