Abstract: Electronic Health Records (EHRs) are used to maintain the history of the Patient’s records. But it is entirely controlled by the hospitals. Patients face a critical need to focus on the details of their own healthcare and restore management of their own medical data. The rapid development of block chain technology promotes a secure healthcare system, including medical records as well as patient-related data. This technology provides patients with an extensive, unaltered records and provides access to EHRs free from service providers and treatment websites. To guarantee the validity of EHRs encapsulated in block chain, we present an attribute-based signature scheme with multiple authorities, in which a patient endorses a message according to the attribute while disclosing no information other than the evidence that he has attested to it. 

Keywords: Electronic Health Record System (EHRs), Blockchain, Multiple  Authorities, Attribute Based Signature  (ABS).
