Patients Data Centre (PDC) is a coming forth patient- centric framework of health data interchange, large scale data centric applications. In which the data is been outsourced to be stored to general IT providers, such as cloud providers and how to assure their private data while being stored in the cloud servers and to untrusted parties. To secure the patients information governs over entree to their own PDC, it is a hopeful method to encrypt the PDC and personal information before outwards. Yet, effects such as danger of privacy view, measurability in key management, compromising entree and efficient user revocation, have continued the most significant disputes accomplishing finegrained, cryptographically imposed information entree assure. In this thesis, propose a new patient data centric role model and a suit of method for information access control to personal profiles put in half-believed servers. To reached close–grained and measurable information entree assure for PDC’s, and gained Distributed Multi Authority-Attribute Based Encryption (DMA-ABE) method to generation cipher text of data through ECC (Elliptic Curve Cryptography) algorithm for encrypt each patient’s data file. Different from past works in assure information outsourcing, focus on the more than one data proprietor security script, and split the users in the PDC scheme into multiple assured area that heavily shrinks the key management complexity for proprietors and consumers. A peak of data privacy is ensured at the same time by working distributed multi-authority ABE. Our scheme also enables dynamic alteration of access policies or file attribute, confirms efficient availability of data that can be needed by users/attribute revocation and break-glass approach under casualty assumption. Extended analytical and observational outcomes are presented which show the protection, measurable and efficiency of proposed system.
