Algorithm 2

EHR generating contract.

 Input: certificate, EHR, DataChainTxID, Agreement

 Output: success of Transaction generation

 if Verify(certificate) == True then

  EHREncrypted = Encrypt(EHR);

  EHR@ = Store(EMREncrypted);

  SPID = Resolve (certificate);

  initServiceChainTx (DataChainTxID.PatientID,

  SPID, Agreement.Ref, Agreement.Instance, EHR.DPlevel, timestmp, Signature, DataChainTxID, EHR@);

  return SUCCESS

 else

  return CERTIFICATION ERROR

 end
