[Retracted] SmartMedChain: A Blockchain-Based Privacy-Preserving Smart Healthcare Framework

Algorithm 1

IoT data generating contract.

 Input: certificate, data

 Output: success of Transaction generation

 if Verify(certificate) == True then

  dataEncrypted = Encrypt(data);

  data@ = Store(dataEncrypted);

  initDataChainTx (data.PatientID, Timestmp, data@, data.DPLevel, Signature);

  return SUCCESS

 else

  return CERTIFICATION ERROR
