Data Protection in the Digital Age: Indian Banking Sector’s Cyber Security Imperative
Sonal Rawal · Journal of international commercial law and technology · 2025
The rapid advancement of technology has transformed the Indian banking sector, leading to the emergence of online and digital banking services such as mobile banking, e-payments, and virtual cards. Innovations including Artificial Intelligence, blockchain, and robotics have further enhanced efficiency and convenience in financial services. However, these developments have also heightened vulnerabilities associated with large-scale data collection and exchange, exposing the sector to significant cyber security threats. Ensuring privacy and data protection has thus become a critical concern, as customers entrust banks with sensitive personal and financial information, creating an obligation of confidentiality. Global incidents, such as the Cambridge Analytica scandal, highlight the potential misuse of data and reinforce the urgency of strong safeguards. Within the Indian context, the issue assumes particular importance due to the increasing digitalization of financial systems and growing reliance on customer data. This paper examines the existing legislative and regulatory framework for cyber security and data protection in the Indian banking sector, analyzing the duties of confidentiality imposed on banks and the adequacy of current mechanisms. It argues that while cyber security is essential to protect data, robust data protection norms are equally necessary to preserve privacy, ensure customer trust, and secure the integrity of the banking system
