Securely Managing the Personal Health Records Using Attribute Based Encryption in Cloud Computing

S.Aarthika

Personal Health Record (PHR) is stored in cloud server for confidential purpose. In past works Identity Based Encryption (IBE) is used. Since twentieth Century Attribute Based Encryption process is used for securely store the PHR data in cloud.PHR is a developing patient-centric model of health information exchange which is often outsourced to be stored at a third party, such as cloud provider. To assure the PHR security, PHR data can be encrypted before outsource. In this process ABE is used to secure data outsourcing. In previous work single owner process is used so that key management is complex. Here proposing a multi owner scenario and divide the user into multiple security domains that reduces the key management complexity for owners and users. A high degree of PHR security is assured by using Multi Authority-Attribute Based Encryption (MA-ABE).By enhancing the MA-ABE, the public user domain security has introduced Distributed Attribute Based Encryption (DABE) concept to independently maintain attribute authorities who contains arbitary number of attributes. The key values are maintained and distributed to authorities. The data privacy is assured in DABE process in PHR
