Sağlıkta blockchaın: Karma diş dönemindeki çocuklar için diş sağlığını iyileştirmeye yönelik akıllı sözleşmeler

Privacy preserving is a matter of great importance in many sensitive fields including financial and healthcare areas. As the blockchain technology has achieved an obvious success in privacy protection at the financial level when the Bitcoin has been introduced in 2008, there are considerable attempts and later on successful projects to introduce the blockchain technology to the healthcare fields, where the patient privacy and access control to the personal information is at high priority. The aim of our thesis mainly considers the introduction of the smart contracts that essentially depend on the technology of blockchain to act as a method for preserving patients' privacies along with improving the reality of dental healthcare providing services. The main focus will be on the treatment plan of the patient by building a smart contract system between multiple partners. Firstly, the problem will be presented that is why there is a need for implementing blockchain system of smart contracts to improve dental healthcare providing? And why we need to provide digital organizing of treatment plan? Secondly, The Blockchain is discussed as a relatively new technology. Thirdly, the design to solve the problem will be proposed and the system of smart contracts will be built, with explanation of the way by which the system will meet the requirement to give the solutions. Finally, there will be a discussion of how proposed design will be implemented. By using "the five types models" our proposed smart contract system is built combining the advantages of the blockchain technology with the smart contracts benefits to provide decentralized, tamper resistant, and privacy preserving properties. The programming language that we have used is Solidity along with proof of authority algorithm on Ethereum blockchain. The proposed blockchain-based smart contract system can provide high level of privacy preservation in the field of patient records in addition to the digitalization of healthcare data.
