Cloud computing is developed as the most influential perfect models in the IT businesses starting late. Because of the progress implied in cloud computing, it will help data innovation in the healthcare industry. In existing healthcare model, outsourcing storage or accessing record from untrusted cloud servers become a challenging issue for security and privacy of data. An access control model is a productive approach that guarantees the information security in the cloud-based framework. In this work, we present a framework to provide expressive, proficient and revocable healthcare access control for a federation-based model using multi-Authority Ciphertext-Policy based Encryption (CP-ABE) scheme. The existing CP-ABE scheme is not able to fulfil all security need to protect healthcare records and control of privilege revocation problem. This research paper proposes the federation-based multi-Authority CP-ABE (F-CPABE) scheme for healthcare system with its subordinate strategies to outline design to healthcare records in federation-based access control scheme. The attribute revocation technique in this scheme helps to resolve both forward and backward security challenges. It has reduced attribute management overhead from a centralized system and also reduces time complexity.
