Mechanisms for Ensuring Confidentiality and Integrity in Digital Information Storage Systems

In the conditions of the digital economy, the security of information assets—particularly data confidentiality and integrity—has become a top priority for information storage systems such as databases, cloud storage, and distributed file systems. This article analyzes modern cryptographic and system-level mechanisms aimed at ensuring these security requirements in data storage systems. In particular, database encryption methods, advanced cryptographic primitives such as Zero-Knowledge Proofs, and the capabilities of blockchain technology in maintaining data integrity are examined. The study includes a comparative analysis of various mechanisms in terms of efficiency, computational overhead, and security level.
