Enhancing Access Control in Healthcare Blockchain Using LSTM-Based Breast Cancer Detection and Blowfish Encryption

Abstract

By providing a secure and transparent platform for the exchange and storage of medical records, blockchain technology revolutionizes data management in the healthcare sector. Patient record confidentiality and integrity are ensured by this decentralized system, which forbids unauthorized access and tampering. Smart contracts speed up processes like insurance claims and simplify administrative work by enabling automated, trustless transactions. Additionally, blockchain facilitates seamless data- sharing by facilitating communication between various healthcare systems. Through a distributed ledger, medical professionals can access a patient’s whole medical history in real time, facilitating better diagnosis and treatment. Despite challenges like regulatory worries, blockchain’s potential for the healthcare industry holds promise for improved patient outcomes, security, and efficiency ( Kumar et al., 2021 ).
