Enhancing Security Through QR Code and Enriched Blowfish Cryptography for Sensitive Data

In today’s digital age, data security is of utmost importance as sensitive information is being stored, processed, and transmitted online. Recent advancement in banking cybersecurity strides in encompassing advanced threat detection, biometric authentication, and the integration of artificial intelligence and block chain to fortify defences against cyber threats. It provides insights into the industry’s evolving strategies for robust financial system security. Confidential information such as personal details, financial information, trade secrets, and other sensitive data must be protected to avoid misuse, theft, or unauthorized access. Compliance with legal and regulatory requirements, maintaining customer trust, preventing cyberattacks, and ensuring business continuity are some other reasons why data security is critical. Implementing effective data security measures such as encryption, access controls, monitoring, and employee training is necessary to safeguard against potential threats and protect the privacy and confidentiality of individuals and organizations. The proposed system provides such protection by using enhanced blowfish algorithm with Attribute based DNA (ADNA) cryptography and Digital Signature Algorithm (DSA) along with a QR key transmission. This way, the system will secure the data shared between both sender and receiver, requiring more cryptanalysis efforts without much impact on performance and computational requirement.
