Abstract:- Cloud computing has become an attractive and viable solution for outsourcing data. People can use cloud storage in pay per use fashion without capital investment. Enterprises from various industries are moving their data to cloud. Personal Health Records (PHRs) is a new model pertaining to health domain which has huge data that can be outsourced to cloud. Unlike data of other domains, the data of healthcare domain is highly sensitive. The patient’s control over his record is very important. To achieve this PHR is encrypted before outsourcing it to cloud storage. There are many concerns pertaining to security such as privacy. Therefore scalable and secure sharing of such data is essential. Recently Li et al. proposed a scheme known as Multi-Authority ABE, which is based on Attribute Based Encryption (ABE). This encryption mechanism when used before outsourcing to cloud ensures that the data owner is assured complete security to his sensitive data. Concurrent and scalable sharing beside high degree of privacy is guaranteed in this scheme. In this paper we implement the scheme proposed by Li et al. with a prototype application that demonstrates the proof of concept. The empirical results revealed that the scheme is effective and support scalable and secure sharing of PHRs. .
