In today's advanced healthcare systems, most smart healthcare platforms use Protected Health Information (PHI) systems to store and share patient data with medical professionals. Despite existing security measures, studies highlight potential risks to personal and health information. This research suggests enhancing PHI security through the BHKEM architecture, integrating Blockchain (B), Honey encryption/decryption (H) with Key Exchange Mechanism (KEM). Blockchain and honey encryption/decryption, known for cryptographic strength, make it challenging for intruders to compromise PHI integrity. The efficient KEM process adds an extra layer of security, reducing Blockchain (BC) overhead. Evaluation shows impressive results, with 98.4, 96.25, and 88.8% gains in storage, block time throughput, and block transaction throughput, and negligible 3.75% latency. Tests against AES confirm KEM's effectiveness against cyber attacks. Simulations and mathematical proofs collectively validate the BHKEM architecture's efficacy in strengthening PHI security in smart healthcare. Furthermore, by integrating Person-Centric Healthcare and Ambient Assistive Technology, the BHKEM architecture not only secures PHI but also enhances patient-centric care, enabling adaptive, context-aware support systems that improve patient outcomes and quality of life.

摘要

In today's advanced healthcare systems, most smart healthcare platforms use Protected Health Information (PHI) systems to store and share patient data with medical professionals. Despite existing security measures, studies highlight potential risks to personal and health information. This research suggests enhancing PHI security through the BHKEM architecture, integrating Blockchain (B), Honey encryption/decryption (H) with Key Exchange Mechanism (KEM). Blockchain and honey encryption/decryption, known for cryptographic strength, make it challenging for intruders to compromise PHI integrity. The efficient KEM process adds an extra layer of security, reducing Blockchain (BC) overhead. Evaluation shows impressive results, with 98.4, 96.25, and 88.8% gains in storage, block time throughput, and block transaction throughput, and negligible 3.75% latency. Tests against AES confirm KEM's effectiveness against cyber attacks. Simulations and mathematical proofs collectively validate the BHKEM architecture's efficacy in strengthening PHI security in smart healthcare. Furthermore, by integrating Person-Centric Healthcare and Ambient Assistive Technology, the BHKEM architecture not only secures PHI but also enhances patient-centric care, enabling adaptive, context-aware support systems that improve patient outcomes and quality of life.
