| Summary: | In this final project, the security system of medical records using blockchain
technology is studied. The Elliptic Curve Digital Signature Algorithm (ECDSA)
and Elliptic Curve Integrated Encryption Scheme (ECIES) procedures are also
used in this final project. This final project also employs elliptic curves and
group law of elliptic curve that will be used in ECDSA and ECIES. Medical
record documents consist of public information and sensitive information, with
sensitive information being encrypted using ECIES to prevent unauthorized access
to this information. The function of ECDSA is to sign public information and the
encrypted sensitive information to ensure data authenticity, data integrity, and nonrepudiation
of the signature on the document. After four blocks of electronic health
record documents, namely EHR, EMR, PHR, and APHR, are formed, the nonce
values with a certain difficulty level will be determined to prevent easy modification
of the block contents. Once all nonce values for each block are found, the
blockchain system for the patient is formed. |
