Abstract :

The security of personal health records is a major problem when patients use commercial Web-based systems to store their health records. Previous access control techniques have many limitations with respect to enforcing access control policies and ensuring data security. In particular, the data has to be stored on a distributed server protected by the access control mechanism and the data owners or patients loses control on their health data from the moment when the data is stored on the server. Therefore, these mechanisms do not fulfill the requirements of data outsourcing scenarios where the unauthorized party storing the data should not have access to the unencrypted data and it is not trusted to enforce access policies. In this paper, we present a new type of attribute-based encryption that is multi-authority attribute-based encryption (MA-ABE) scheme which is used to enforce patient/organizational access control policies. In MA-ABE[8][9], the data is encrypted according to an access policy over a set of attributes. The various access policy specifies which attributes a user needs to have in order to decrypt the encrypted data. Once the data is encrypted, it can be safely stored in an untrusted distributed server such that every user can download the encrypted data but only authorized users who satisfy the access policy can decrypt. The originality of our construction is that attributes can be from two security domains: personal domain (e.g. family, friends) and privatedomain (e.g. hospital staff, insurance company).
