A secure framework for medical image storage based on multi-cloud

Cloud-based medical image is a promising technology. In fact, it provides cost-efficient services and allows collaboration between healthcare ecosystem. Despite its multiple advantages, migrating to this new paradigm arises several challenges: technical, legal and managerial. Recently, the healthcare sector has been interested in adopting this technology to improve the quality of medical care. In this study, we propose a secure framework based on multi-cloud environment. For that, we use a secret share scheme to improve data confidentiality. Moreover, reversible watermarking technique is proposed to verify the integrity of medical image.
