Breast Cancer Detection Using Modified Hough Transform
Biomedical Research • 2018
Breast cancer results from uncontrolled cell division and can spread through the bloodstream. This work proposes a tumor detection approach using geometric, texture, and gradient features. Regions of interest (ROIs) are identified using the Hough transform, then extracted from mammogram images for analysis. A set of 22 features is computed to distinguish between normal and cancerous tissues. The results are validated against expert radiologist assessments to evaluate the system's accuracy and effectiveness.

FarmIns: Blockchain Leveraged Secure and Reliable Crop Insurance Management System
Springer • July 23, 2023
Traditional crop insurance faces challenges such as delayed claim processing and fraud, leading to significant costs for both farmers and insurers. This paper proposes FarmIns, a blockchain-based framework that enables secure and transparent insurance agreements through smart contracts. By integrating Internet of Agro-Things (IoAT) devices and CCTV-based monitoring, FarmIns generates verifiable farm data to support faster and more reliable claim validation. Additionally, it functions as a decision support tool for both insurers and farmers, improving efficiency and trust in the insurance process.
hChain 3.0: Leveraging Blockchain for Personalized Patient Assessments and Improved Medication Adherence in Chronic Care Management
Chronic Care Innovation • 2024
This work explores blockchain applications in chronic care management, focusing on personalized patient assessment mechanisms and medication adherence tracking. The hChain 3.0 framework utilizes distributed ledger technology to create secure, transparent, and patient-centric care management systems.
hChain: Blockchain Based Large Scale EHR Data Sharing with Enhanced Security and Privacy
ArXiv • May 19, 2025
This article offers a blockchain-based smart healthcare system using IoMT devices for continuous patient monitoring. In addition, it employs edge resources in addition to IoMT devices to have extra computing power and storage to hash and encrypt incoming data before sending it to the blockchain. Symmetric key is utilized to keep the data private even in the blockchain, allowing the patient to safely communicate the data through smart contracts while preventing unauthorized physicians from seeing the data. Through the use of a verification node and blockchain, an asymmetric key is used for the signing and validation of patient data in the healthcare provider system. In addition to other security measures, location-based authentication is recommended to guarantee that data originates from the patient area. Through the edge device, SHA256 is utilized to secure the data's integrity and a secret key is used to maintain its secrecy. The hChain architecture improves the computing power of IoMT environments, the security of EHR sharing through smart contracts, and the privacy and authentication procedures.
hChain 4.0: A Secure and Scalable Permissioned Blockchain for EHR Management in Smart Healthcare
ArXiv • May 20, 2025
The proposed approach introduces a high-privacy method in which health data are encrypted using the Advanced Encryption Standard (AES) for time-efficient encryption, combined with Partial Homomorphic Encryption (PHE) to enable secure computations on encrypted data, thereby enhancing privacy. Moreover, it utilizes private channels that enable isolated communication and ledger between stakeholders, ensuring robust privacy while supporting collaborative operations. The proposed framework enables anonymized health data sharing for medical research by pseudonymizing patient identity. Additionally, hChain 4.0 incorporates Attribute-Based Access Control (ABAC) to provide secure electronic health record (EHR) sharing among authorized parties, where ABAC ensures fine-grained permission management vital for multi-organizational healthcare settings. Experimental assessments indicate that the proposed approach achieves higher scalability, cost-effectiveness, and validated security.
