Exploring Approaches for Secure Medical Image Storage and Retrieval: A Comprehensive Survey

Abstract

Medical images, the backbone of digital healthcare, hold critical information for accurate diagnoses and lead to advancements in medical research. However, the increasing amount of these images often entails storage on third-party cloud servers where security and privacy are major concerns. In digital healthcare operations, securely storing and retrieving medical images involves considerable difficulties. This paper investigates how existing techniques handle medical images while maintaining performance and security. It analyzes secure storage strategies like blockchain and encryption and covers secure retrieval strategies like indexing that preserve data security and effective search capabilities. The paper provides insights into the advantages, disadvantages, and applicability of current systems through an extensive evaluation. It also offers thoughtful suggestions and future research paths that could establish a trustworthy and secure medical image management.
