Abstract—The rapid advancement of IoT has greatly revolutionized the healthcare sector, giving rise to the Internet of Medical Things (IoMT). While IoMT has significantly enhanced healthcare services by incorporating smart and intelligent sensor devices into hospital settings, it also introduces critical challenges related to security and privacy. As more devices connect to the IoMT, the need for robust security and privacy protection grows, particularly due to the sensitive nature of medical data. Medical information contains extensive personal details, making it vulnerable to privacy breaches and complicating its sharing. So, it is crucial to establish a framework that ensures the secure and efficient exchange and storage of vast amounts of medical data. Current approaches mainly support image-level sharing and rely on standard cryptographic algorithms. To overcome these limitations, this paper introduces a healthcare information security storage solution based on IPFS and Blockchain. This research enhances the security of decentralized storage by employing a hybrid crypto-compression scheme based on Wavelet Transform and Elliptic Curve Cryptography (ECC). This method utilizes first a joint compression and encryption strategy, ensuring secure encryption of medical data while preserving its privacy and confidentiality. The encrypted medical information is then stored on the InterPlanetary File System (IPFS), which provides a decentralized and secure storage solution. Instead of transmitting the medical data itself, only the Content Identifier (CID) generated by IPFS is sent over a public channel. This solution integrates IPFS technology to reduce the blockchain’s storage burden. The finding confirms the feasibility of the proposed approach, ensuring both the secure storage and integrity of medical information while effectively addressing security challenges in IPFS. By combining these concepts, the approach aims to establish a secure, reliable, and confidential ecosystem tailored for the evolving landscape of healthcare data management in IoMT environments.
