A Survey on Healthcare Data: A Security Perspective

With the remarkable development of internet technologies, the popularity of smart healthcare has regularly come to the fore. Smart healthcare uses advanced technologies to transform the traditional medical system in an all-round way, making healthcare more efficient, more convenient, and more personalized. Unfortunately, medical data security is a serious issue in the smart healthcare systems. It becomes a fundamental challenge that requires the development of efficient innovative strategies towards fulfilling the healthcare needs and supporting secure healthcare transfer and delivery. This article provides a comprehensive survey on state-of-the-art techniques for health data security and their new trends for solving challenges in real-world applications. We survey the various notable cryptography, biometrics, watermarking, and blockchain-based security techniques for healthcare applications. A comparative analysis is also performed to identify the contribution of reviewed techniques in terms of their objective, methodology, type of medical data, important features, and limitations. At the end, we discuss the open issues and research directions to explore the promising areas for future research.

A Secure and Privacy-Aware Smart Health System with Secret Key Leakage Resilience

With the development of the smart health (s-health), data security and patient privacy are becoming more and more important. However, some traditional cryptographic schemes can not guarantee data security and patient privacy under various forms of leakage attacks. To prevent the adversary from capturing the part of private keys by leakage attacks, we propose a secure leakage-resilient s-health system which realizes privacy protection and the safe transmission of medical information in the case of leakage attacks. The key technique is a promising public key cryptographic primitive called leakage-resilient anonymous Hierarchical Identity-Based Encryption. Our construction is proved to be secure against chosen plaintext attacks in the standard model under the Diffie-Hellman exponent assumption and decisional linear assumption. We also blind the public parameters and ciphertexts by using double exponent technique to achieve the recipient anonymity. Finally, the performance analysis shows the practicability of our scheme, and the leakage rate of the private key approximates to 1/6.

The Critical Need for Empowering Leadership Approaches in Managing Health Care Information Security Millennial Employees in Health Care Business and Community Organizations

According to the Ponemon (2012) Third Annual Benchmark Study on Patient Privacy & Data Security, 94 percent of healthcare organizations surveyed suffered at least one data breach; 45 percent experienced more than five in the past two years. Data breaches cost the U.S. healthcare industry an average of $7 billion annually (Ponemon, 2012). Electronic health records are becoming more pervasive at hospitals and clinics in the United States. Meanwhile, healthcare organizations are taking small steps toward meaningful exchange and secure data security of patient information. This has created a need for new expertise in health data security from a newly degreed and young in information security professionals from the “Millennial Generation”. This chapter explores the attraction, recruitment, and retention of younger-generation professionals with critical and emerging health information security skills.
