Secure and Scalable IoT Healthcare System with Blockchain Encrypted Framework and AES Encryption

Problem Definition

The problem at hand is the vulnerability of patient data in blockchain-based systems when transmitted over the cloud, leaving it open to potential attacks. This insecurity instills a feeling of unease among patients, leading them to withhold sensitive information. Existing solutions have proposed encrypting the data using various algorithms to mitigate these risks, but there is a scarcity of research in this area. The few studies that have explored encryption algorithms often suffer from high complexity and inefficient processing times for encryption and decryption processes. Therefore, in order to address the growing concerns about unauthorized access to patient data, a novel blockchain-based IoT framework for healthcare systems is essential to provide a secure and reliable platform for sharing sensitive information while maintaining data integrity.

Objective

The objective of the proposed work is to develop a novel blockchain-based IoT framework for healthcare systems that focuses on enhancing the security and accessibility of patient information. This framework aims to protect patient data from unauthorized access by utilizing encryption algorithms such as AES and SHA-256. The goal is to establish a secure platform for sharing sensitive information between patients and healthcare service providers, while also addressing issues related to discrepancies in medical records. The use of multi-layer blockchain-based IoT data security approach, with encryption algorithms like AES, DSA, and RSA, will ensure the reliability and trustworthiness of patient data. The proposed framework also aims to provide a robust security procedure for managing healthcare systems and securing sensitive information in IoT cloud-based data servers.

Additionally, the research will involve comparing the performance of different encryption algorithms to validate the effectiveness of the proposed security measures.

Proposed Work

By analyzing the existing literature, it was found that while numerous blockchain-based methods have been proposed for data security and integrity, there is a lack of focus on encryption algorithms to secure data while transmitting over the cloud. This gap in the research led to the proposal of an improved blockchain-based IoT framework for the healthcare system, aimed at protecting patient data from unauthorized access. The main objective of the proposed work is to enhance the security and accessibility of patient information by utilizing encryption algorithms such as AES and SHA-256 to build a trustworthy relationship between patients and healthcare service providers. The proposed framework aims to address the issue of discrepancies in medical records by implementing a blockchain approach that allows seamless updates and access to patient data across different medical institutions. The proposed work involves the development of a multi-layer blockchain-based IoT data security approach that securely stores patient information in an encrypted form to prevent unauthorized access.

By implementing encryption algorithms such as AES, DSA, and RSA in the second layer of the IoT framework, the reliability and trust between patients and healthcare providers are enhanced. The use of AES encryption algorithm specifically is chosen for its key expansion ability, which adds an extra layer of security to the sensitive medical information of patients. The encrypted data is further divided into blocks and hashed for double-layer security before being stored in the cloud layer. Through this approach, the proposed framework aims to provide a robust and effective security procedure for managing healthcare systems and securing sensitive information in IoT cloud-based data servers. The research also involves comparing the performance of different encryption algorithms to ensure the effectiveness of the proposed security measures.
