The digital world has become an integral part of our daily lives, and with this increasing reliance comes a growing threat of cybercrime. Hackers and cybercriminals can exploit the open nature of the internet to access sensitive information, steal money, and disrupt operations. To combat this issue, organizations and individuals must implement advanced layers of security to protect their data and financial information. One key aspect of this security is data encryption, which uses mathematical algorithms to scramble data, making it unreadable to unauthorized parties. Cryptology is the science of encryption and plays a vital role in protecting data from cybercrime. It provides various layers of security such as data security, organizational security, and identity management, to ensure that only authorized personnel can access sensitive information. Different encryption methods such as RSA, Elliptic Curve, DES, and AES are commonly used, but each has its own unique set of strengths and weaknesses. Recently, a new approach to prevent cybercrime is proposed, which is based on blockchain technology. Blockchain is a distributed ledger technology that allows data to be stored in a decentralized and secure way. This makes it difficult for hackers to tamper with the data, and ensures the integrity of the information. By using blockchain-based cryptography methods, we can add an extra layer of security to the data, making it even more difficult for cybercriminals to access sensitive information.
