BDPPP: A Novel Blockchain-Based Data Protection and Privacy-Preserving Framework for the IOT Healthcare Applications
Main Article Content
Abstract
In this research, the Blockchain-Based Data Protection and Privacy-Preserving (BDPPP) framework for IoT healthcare applications was designed and established to improve the data security and privacy of IoT healthcare applications by adopting blockchain and other cryptographic techniques. The study adopted a descriptive-analytical approach that involved a harmonious synthesis of several research papers to establish important security threats in IoT systems, emphasizing healthcare infrastructure. Both interviews and case studies were conducted with healthcare professionals and IT specialists to examine data privacy issues and weaknesses of IoT devices. The BDPPP framework was developed exploiting blockchain technology framework and cryptographic approaches including homomorphism encryption and zero-knowledge proofs to protect the information of the patient. Both smart contracts and edge computing were also applied to manage access to data as well as enhance real-time computation. The performance of the healthcare IoT network was assessed through a range of statistical parameters including latency, throughout, as well as encryption overhead were tested in a simulated IoT network environment. The findings showed that the proposed BDPPP framework provided maximum data confidentiality (encryption) at 100 percent and achieved high privacy standards (95% privacy performance) over IoT devices and also proved scalability up to 5000 IoT devices. Statistical tests used included; Logistic regression results showed that demographic characteristics including age and health conditions were not predictors of consent status. This means that the framework implemented in this study also achieved a low latency of 120 ms and a high through-put of 200 TPS despite the added layer of encryption. Overall, the proposed BDPPP framework is an innovative decentralized approach for further improvement of the IoT HC and data protection and privacy.
