The purpose of this study is to analyze the legal responsibility of banks towards customers in cases of personal data leaks, examine the extent of legal protection provided to customers, and describe efforts that can be made to minimize the risk of data leaks. This study uses a literature study method by collecting and analyzing various legal sources, such as laws and regulations, court decisions, journals, and literature related to data protection in the banking sector. The results of the study indicate that banks have legal responsibilities based on the Personal Data Protection Law (UU PDP) and banking provisions to maintain the confidentiality of customer data. If a data leak occurs, the bank can be subject to administrative, civil, or even criminal sanctions depending on the level of negligence. In addition, this study found that customers have the right to claim compensation if the data leak causes material or immaterial losses. However, the effectiveness of law enforcement still faces challenges, such as lack of customer awareness and complexity of evidence. Therefore, it is necessary to strengthen regulations, improve cybersecurity systems by banks, and educate customers to mitigate the risk of data leaks. The implications of this study are expected to provide recommendations for regulators and banking industry players in strengthening the protection of customer personal data.

This research aims to explore the role of the Deposit Insurance Corporation (LPS) in protecting customers when banks fail. The research methods used include policy analysis, case studies of failed banks, and reviews of related laws. It is hoped that the research results will provide a deeper understanding of the effectiveness of the legal protection provided by LPS to customers in the context of bank failures and the related compensation claims process. The Deposit Insurance Corporation (LPS) has a crucial role in protecting customer deposits when banks experience liquidation. In this context, LPS functions as a legal protection strategy for customer deposits held in banks. This action is important to maintain public confidence in banking amidst economic uncertainty. In response to the 1998 monetary crisis, the Indonesian government issued a policy of guaranteeing bank payments, including public deposits, through LPS. The importance of LPS is revealed when banks experience failures that have the potential to threaten the security of customer funds. In this situation, LPS guarantees the customer's refund up to a certain limit, providing the necessary financial protection. This creates a sense of security for customers and promotes banking system stability. With LPS, customers can be assured that their funds are safe even if unexpected events occur in the banking world. The role of LPS as a deposit insurance institution is inherent in the government's efforts to regulate and supervise the financial sector. LPS plays a role as the front guard in protecting customer interests, maintaining financial system stability, and preventing potential losses that could arise due to the possibility of bank failure.
