HealthCare Monitoring Solution with Decryption Outsourcing by Parallel Computing in Cloud

Mr.K.Ganesan, Mr.C.Vijayakumaran

Mobile devices have reached a wide development range and proved its assistance in health care with the combination of Cloud Server. The health monitoring offers various services such as monitoring of physiological data through remote sensors. These are achieved in collaboration with Cloud Servers providing software as a service, thus providing healthcare solutions at low cost. But there is a high risk of security violation of patient’s private data as there is a lack of data management. The proposed approach identifies the existing system’s design problems and proposes private key proxy re-encryption scheme that helps in reduction of computation complexity of securing data. This system is used to transmit patient’s personal information from smart mobile phone to a monitoring system installed by a health service provider in cloud, such that the third party collaborator of the healthcare company is then responsible for private key distribution to clients which can be used for querying his data. When the user requires accessing his data, he/she passes the private key and the healthcare company index to the collaborator, who in turn inputs the master key to the cloud that provide parallel access to the databases. The user finally receives a token from collaborator and pass to the cloud, which respond back to the user with semi-decrypted data and final decryption takes place at the end user’s place. Hence the cloud has no reach to unencrypted private data of the user. Also the advantage of this model is drastically reduces the workload of encryption/decryption tasks by outsourcing them to the cloud server.
