[Emerging Technologies and Threats] Which of the following best explains the business requirement a healthcare provider fulfills by encrypting…

The primary business requirement for a healthcare provider to encrypt patient data at rest is driven by regulatory compliance, most notably the Health Insurance Portability and Accountability Act (HIPAA). HIPAA's Security Rule mandates the protection of electronic Protected Health Information (e-PHI). Encrypting data at rest ensures its confidentiality, directly addressing the core requirement to protect patient privacy. This control is critical for supporting the "portability" aspect, as it allows data to be stored on mobile devices, laptops, or backup media and moved securely without exposing sensitive information if the physical media is lost or stolen.

A. Securing data transfer between hospitals: This describes protecting data in transit (e.g., using TLS), not data at rest (stored on a disk).

B. Providing for non-repudiation of data: Non-repudiation ensures a party cannot deny an action. This is typically achieved through digital signatures or audit logs, not by encrypting stored data for confidentiality.

C. Reducing liability from identity theft: While a positive outcome, this is a secondary benefit. The primary business requirement is the direct mandate to protect patient privacy, which in turn reduces liability.

1. U.S. Department of Health & Human Services (HHS). The Security Rule

45 C.F.R. § 164.312(a)(2)(iv). The rule lists "Encryption and Decryption" as an addressable implementation specification for access control to e-PHI. The overall purpose of the Security Rule is to "ensure the confidentiality

integrity

and security of electronic protected health information

" which directly aligns with protecting privacy.

936-943. This article discusses the balance required by HIPAA: "The HIPAA Security Rule... requires covered entities to implement safeguards to protect the confidentiality

integrity

and availability of e-PHI... Encryption is one such technical safeguard that can be used to protect e-PHI at rest and in transit." This highlights the link between encryption and the confidentiality (privacy) needed for interoperability (portability). DOI: https://doi.org/10.1001/journalofethics.2016.18.9.sect1-1609

3. Johns Hopkins University. IT Policies: 5.2 - Data and Information Security and Protection. In its policy for protecting sensitive data (including PHI)

the university mandates encryption for data at rest on portable devices and media. This demonstrates the real-world application of encryption to protect privacy while enabling the portability of data on various devices

a core business need in healthcare and research.
