An multi-authority attribute based encryption for personal health record in cloud computing

One of the major problem existing in the cloud is to manage or to secure the data's from the unauthorized persons. Here in medical field, Patient — centric model describes about the patients Personal Health Record (PHR), where the health information is to be secured from the third party servers. The security scheme Multi Authority Attribute Based Encryption (MA-ABE) is used to protect the patient's record. The personal and professional file access is done in a structured way and policy management is also maintained by using MA-ABE. The proposed results are compared with the existing CP-ABE and the results shows that MA-ABE model is more secured with less delay.
