An Efficient Multilayer approach for Securing E-Healthcare Data in Cloud using Crypto – Stego Technique

Healthcare data has been moving to cloud platforms in recent years, which has increased accessibility and scalability but also raised security issues. Ensuring data integrity and safeguarding private health information from unwanted access are critical. This paper presents a comprehensive strategy to integrate effective Elliptic Curve Cryptography ECC-AES with steganography techniques to improve the security of healthcare data in the cloud. ECCAES is especially well-suited for cloud situations with limited resources since it provides strong security with reduced key sizes. Confidentiality is guaranteed by encrypting healthcare data using ECC- AES before storage, reducing the possibility of data breaches. Steganography techniques are also integrated to improve security against skilled adversaries by adding an extra degree of obfuscation by concealing encrypted data inside innocuous files or images. Strict key management procedures, access control systems, and frequent security audits are important components of the proposed system that ensure adherence to Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR) compliance requirements pertaining to healthcare data protection. Programs for employee awareness and training are also crucial for reducing the likelihood of human mistakes. Healthcare businesses can safely use cloud technology while protecting patient data integrity and privacy by putting in place multi-layered security safeguards. The proposed system provides the multilayer security on healthcare data in cloud environment than other existing systems.
