ATTRIBUTE BASED ENCRYPTION IN PERSONAL HEALTH RECORD

Abstract

Cloud computing is newly formed technology in which resources of the computing infrastructure are used as services on web. It easily handles new challenges for the PHR data security and access to the PHR data when user wants to transmission of data for sharing on cloud, which is not between same trusted owners of data. To provide security against the unauthorized server, previously or existing method usually used is cryptography, encrypting the data using key which is only decrypted by the authorized user. It is hard to manage key arrangement and management of data. It is not suitable and well scale. The scalability and security related to access control of data still not remove. In this, the new access policy is introduced that the encryption is based on data attributes. Attribute Based Encryption method (ABE) used to encrypt each patient’s PHR data file. It is different from previously used method of data outsourcing, in that we considering the multiple PHR data owner. This technique reduces the key arrangement problem of owner and user. We achieve the goal data security and sharing problem of data between multiple domain data owner is resolved. After extensive analysis and test results shows that our system technology are highly suitable and properly secure under the previous security techniques[1][2][3]
