Secure Medical Data Computation using Virtual_ID Authentication and File Swapping

PHR provides users with a great deal in leakage of sensitive information. However, securing the sensitive medical data also brings very serious security problems, especially for the data security which is stored in the medical cloud data. Once the data is leaked to a third party, then the data privacy has become a major problem, mainly such as authentication, availability of data, confidentiality etc., and which is to be taken into consideration very effectively. An authentication scheme based on virtual smartcard using hashing function for medical data is proposed to solve the problem of in which the illegal users access the resources of servers. Here, we also maintain PHR sensitive data in the cloud by using file swapping concept. Once the user access the data. The user data will be swapped into different places by file swapping concept, so the file will be more secured and no one can hack or theft our data.
