Healthcare organizations in the United States are being asked more and more to use artificial intelligence (AI) in their work and patient care. AI can help make better decisions, improve patient care, and make administrative tasks easier. But using AI with healthcare data also brings challenges. It raises concerns about keeping data private, safe, and following the rules. Since health information is very sensitive, healthcare leaders such as practice administrators, owners, and IT managers need to know how to use technologies that protect patient data while still benefiting from AI.
One approach to handle these challenges is using Privacy Enhancing Technologies (PETs). These include methods like differential privacy, federated learning, and cryptographic protocols. PETs help meet healthcare data rules like HIPAA and new federal guidelines. They do this while letting AI study and learn from complex healthcare data.
This article explains how PETs and differential privacy work with AI in healthcare, especially in the U.S. It covers rules, technical setups, and strategies for healthcare administrators and IT workers who want to safely use AI tools.
AI in healthcare needs large amounts of patient data. This includes data like electronic health records (EHRs), medical images, and other personal health information. Often, this data is stored on cloud servers or advanced computers. These tools allow strong data analysis but also increase the risk of unauthorized access and data leaks. Since healthcare data is sensitive, a privacy mistake can cause legal problems, loss of patient trust, and harm to patients, such as discrimination or emotional distress.
Privacy Enhancing Technologies (PETs) use technical and organizational ways to lower these risks. PETs cover many strategies to keep data safe and anonymous but still useful for AI training and use. For example, PETs protect data by reducing exposure, encrypting transmissions, and hiding identities without losing the value found in the data.
These technologies are more important now because of growing rules. The U.S. Department of Health and Human Services (HHS) Office for Civil Rights (OCR) and the Federal Trade Commission (FTC) have made HIPAA rules stricter. This happened especially after recent cyber attacks affecting many patients. These agencies warn about certain online tracking methods that were ignored before. They also punish organizations that don’t protect health information properly. For example, in 2023, the FTC charged GoodRx Holdings $1.5 million for not handling health data privacy correctly.
Several PETs help protect healthcare data used in AI. Healthcare administrators and IT staff should know the strong points and drawbacks of these technologies.
Federated learning lets AI learn from many separate data sources, like hospitals or clinics, without sharing raw patient data in one place. Instead of collecting all sensitive records centrally, AI goes to each site to learn and update on the data locally. These updates are then combined to make a global AI model without showing individual patient data.
This method fits well with HIPAA privacy rules. It also lowers the chance of cyber attacks. More healthcare places are now using federated learning to keep data private while working together.
Differential privacy adds random “noise” to datasets or AI outputs to stop anyone from identifying specific patients. This method tries to keep data useful while protecting privacy. It lets researchers and AI study healthcare trends and results without sharing personal details.
The National Institute of Standards and Technology (NIST) has draft rules on differential privacy, showing it’s becoming important in federal rules. Even so, this method can make AI models less accurate. It might also cause fairness problems by favoring common data patterns. Healthcare groups must balance privacy benefits with AI model quality.
Homomorphic encryption allows calculations on encrypted data without decrypting it first. This lets AI work on health data in the cloud without exposing information during sending or storing. Although it needs lots of computing power, this technology is growing, especially for AI tasks done off-site where data privacy is very important.
SMPC lets several parties work together on a calculation using their private inputs without sharing those inputs with each other. In healthcare AI, SMPC helps institutions train models together for jobs like fraud detection or diagnosis aids, all while keeping patient data private.
Data anonymization removes personal identifiers permanently. Pseudonymization replaces identifiers with fake labels that can be reversed but only under strict rules. Both methods help lower privacy risks. But care is needed to avoid re-identifying patients by linking data with public sources.
In 2024, HIPAA rules are changing to keep up with new healthcare methods and AI technology. The HHS OCR is finishing updates to the HIPAA Privacy Rule. These updates make it easier to coordinate care based on value and support patient rights related to substance use disorder (SUD) treatment records with one prior consent. The goal is to reduce administrative work but keep privacy strong.
At the same time, authorities are increasing enforcement of cybersecurity and privacy rules to protect patient health information (PHI). OCR and FTC have warned about third-party online tracking tools due to privacy risks. These warnings influence healthcare IT practices.
Using AI with patient data also must follow the 21st Century Cures Act Information Blocking Rule. This rule requires fast and clear sharing of PHI. Providers who do not follow it may face penalties like Medicare payment cuts and losing access to CMS programs.
To handle these complex rules, healthcare providers and managers must create strong data policies. This includes doing detailed Data Protection Impact Assessments (DPIAs), updating security policies, assessing risks, and training staff on new rules.
AI tools that automate tasks can improve how healthcare offices run. They help with activities like booking appointments, sorting patients, billing questions, and answering phones. Companies like Simbo AI offer AI-based front-office phone automation. In these tools, it is very important to keep patient information safe because calls contain sensitive data.
Using PETs in automated workflows helps healthcare balance efficiency and privacy. For example:
As HIPAA cybersecurity rules get stricter in 2024, automated workflows must have strong protections. These include regular phishing tests, checking system logs, planning to reduce risks, and removing old systems. OCR highlights these steps in recent advice.
Administrators should make sure AI automation platforms follow these standards and use PETs to stop unauthorized PHI leaks. Including these technologies in telephony and scheduling systems lowers breach risks and helps meet HIPAA rules.
Although PETs offer good solutions, there are real problems to using them widely:
To solve these problems, administrators and IT staff can work with trusted technology providers who know AI and PETs. They should attend ongoing training and join industry groups to share good ideas. Using many layers of privacy controls instead of just one method gives better protection.
The Privacy Enhancing Technologies market was worth about $2.45 billion in 2023. It is expected to grow by 25% each year until 2032. North America leads this growth because of strict rules like HIPAA and CCPA, plus rising cybersecurity threats in healthcare.
Big tech companies like IBM, Microsoft, and Google are working on homomorphic encryption and federated learning for secure computing in healthcare. Startups and universities are speeding up research on multi-party computation and quantum-safe cryptography.
Privacy-as-a-Service (PaaS) models are becoming popular. These give healthcare groups scalable PET solutions that meet compliance without needing big internal development. This helps practices of all sizes meet privacy needs more easily.
Using AI in healthcare work and clinical care offers many benefits but also brings serious privacy and safety duties. Medical practice administrators and IT managers in the United States must understand why using Privacy Enhancing Technologies and differential privacy is important to follow HIPAA and federal cybersecurity rules.
Key recommended steps include:
By following these steps, healthcare groups can use AI-driven tools effectively while protecting patient data and following the law.
Pending updates include exceptions to the ‘minimum necessary’ standard to better support individual-level care coordination and case management, shortened timeframes for responding to PHI access requests, and elimination of requirements like signed acknowledgments of Privacy Practices, all aimed at reducing administrative burdens and enhancing coordinated, value-based care.
The alignment facilitates use and disclosure of SUD treatment records based on a single prior patient consent covering all future uses for treatment, payment, and operations while expanding prohibitions on disclosures in legal proceedings without court orders, enhancing patient privacy and simplifying provider compliance.
The NPRM proposes restricting use and disclosure of reproductive health PHI in investigations or proceedings, requiring providers to obtain written attestation that requests are not for prohibited purposes, thereby strengthening privacy safeguards following the Dobbs decision and protecting patient-provider trust.
The OCR expanded the definition of PHI to include information from website visits under certain conditions, considering site visits as evidence of a patient-provider relationship. This imposes HIPAA obligations on data collection via tracking technologies, raising privacy and security risks for providers and health app developers.
The FTC has pursued companies for deceptive sharing of individually identifiable health information, violations involving tracking technologies, and false privacy representations, highlighting plans to monitor AI tool developers for privacy compliance and emphasizing protection of sensitive health data including biometric and reproductive information.
OCR focuses on risk assessments, phishing attack prevention, timely review of system logs, and retiring obsolete IT infrastructure. The HHS Cybersecurity Performance Goals aim to enhance sector-wide resiliency against cyber threats, with potential updates to the HIPAA Security Rule to integrate stronger cybersecurity requirements in 2024 and beyond.
The Proposed Rule includes financial penalties and public disclosure of information blocking incidents to deter providers from withholding PHI. Enforcement may reduce Medicare payments or bar participation in CMS programs, incentivizing timely and transparent sharing of PHI to support patient access and interoperability.
HIPAA permits use of de-identified data without restrictions; however, risks remain for re-identification due to large and diverse datasets. Differential privacy and privacy-enhancing technologies are being evaluated to mitigate these risks, although adoption and regulatory incorporation are under development.
PETs aim to reduce privacy risks in data processing by improving security, disassociability, and manageability of data. Differential privacy adds noise to data outputs to prevent identification of individuals. NIST guidelines guide federal and healthcare entities on integrating these technologies to safeguard AI training and use under evolving privacy standards.
Organizations should review and update privacy and security policies, conduct data mapping to identify PHI flows, strengthen cybersecurity practices, and stay informed on federal rulemaking related to AI use and privacy. Early adoption of PETs and alignment with NIST guidelines can support compliance and risk reduction in 2024 and beyond.
