In this research article, the design and implementation of security mechanism by user authentication for voting system based on Fernet encryption and Blockchain technique is presented along with the simulation results. Blockchain is a technology that has gained a lot of attention recently because it uses an immutable distributed ledger to offer security and anonymity. It serves as the foundation for bitcoin, the most well-known cryptocurrency. It is commonly used in situations where trust is given top priority because of its reliable consensus mechanism and tamper-proof data storage. The key is a unique, random string of data that is used to both encrypt and decrypt the message. Without the key, Fernet promises that a message that has been encrypted with it cannot be altered or deciphered. Data may be transferred and stored securely in cloud systems using these technologies. In this paper, we provide a method for developing a trustworthy, impenetrable, and effective voting system using Blockchain technology along with Fernet encryption method. The application voting uses several security layers and OTP to prevent unauthorized access and manipulation of votes. We have also implemented a two-factor authentication (2FA) system and a third-party audit system to ensure the integrity of the voting process. We have also made our system tamper-proof by using hashing cryptographic techniques by encrypting the votes. The system is also equipped with an automated alert system to notify the user of any suspicious activity. Finally, we have tested the system and have found it to be secure and reliable.
