In the digital age, health data has moved online at an astounding rate. Personal health information and records that once existed solely on paper in doctor's offices and hospitals are now stored digitally, transmitted electronically, and accessed through websites and mobile apps. This incredible convenience has opened the door to unprecedented access and use of medical data that can enhance healthcare. However, it has also created new threats and vulnerabilities that compromise patient privacy and data security.


Recent large-scale health data breaches highlight the need for more vigilance and care around how sensitive medical information is handled. Patients are often unaware of the many ways their data is gathered, used, and shared by various healthcare stakeholders. They may not realize the extent to which their information is accessible online or how exposed it can be to cyberattacks and data breaches. As technology continues advancing rapidly, healthcare organizations, technology vendors, lawmakers, and patients themselves all share responsibility for safeguarding medical data privacy and security. There is an urgent need to examine the risks, implement thoughtful solutions, and restore patient trust and control over personal health information in the digital age. This discussion explores key areas where health data security is most at risk and provides insights on how to better protect patient privacy.


Health Data Breaches

In recent years, there have been several high-profile data breaches that exposed highly sensitive patient information. In 2015, health insurer Anthem revealed that hackers had gained access to records containing personal data like names, birthdays, social security numbers, and medical IDs for nearly 80 million people. In 2018, hackers were able to access personal information from Singapore's government health database, compromising information on 1.5 million patients.


These large-scale breaches have serious consequences. They undermine patient trust and damage the reputations of healthcare organizations. There are also significant risks of medical identity theft if social security numbers and other information get into the hands of criminals. Patients whose data is exposed may also face discrimination from employers, lenders, or insurers who find out about certain medical conditions. 


Data breaches also highlight vulnerabilities in legacy health IT systems and electronic medical records. As more providers transition to digital records, it's critical that security is built into these systems from the start. Strong encryption, access controls, and routine audits can help safeguard sensitive patient data. Ongoing staff training is also key, as many breaches originate from employee errors like lost laptops or misdirected emails.


Digital Health Records


The healthcare industry has been rapidly transitioning from paper-based records to digital health records in recent years. This shift to electronic health records (EHRs) has enabled easier storage, retrieval and sharing of patient data between healthcare providers. However, it has also introduced new risks related to patient privacy and security.


EHR systems store sensitive patient information such as medical history, examination notes, test results, and billing data. This data is often linked across multiple healthcare providers like hospitals, clinics, pharmacies and specialists. While EHRs improve coordination of care, their interconnected nature means a data breach at one facility can expose patient data across multiple access points.


Centralized databases of EHRs present an attractive target for hackers. Breaches can expose private health details of thousands of patients at once. A 2018 attack on a pediatric clinic compromised data of over 55,000 patients. Medical identity theft is also a rising problem - patient information in EHRs can be used to fraudulently obtain healthcare services.

Apart from external attacks, insider threats - like snooping by employees - are a key concern. Encryption, access controls and patient consent protocols are vital when implementing EHR systems. Ongoing staff training and audits help minimize internal abuse of health data access privileges. Overall, the digitization of healthcare data requires vigilant and proactive measures to protect patient privacy. As EHR adoption grows, data security must be an integral focus.


Mobile Health Apps


The use of mobile health apps has exploded in recent years. These apps allow users to track health data like steps, heart rate, sleep patterns and more. Many connect to wearable devices and sync data to create comprehensive health profiles. However, mobile apps present risks to patient privacy in several ways:


  • Data collection - Apps can collect very sensitive health information like heart rate, blood pressure, menstrual cycles, etc. This data is stored on users' phones and often transferred to the app company's servers. There are questions around how securely this data is stored and who has access.  

  • Third-party sharing - App privacy policies often allow data sharing with third parties for purposes like advertising or analytics. Users may not realize how widely their health data is being distributed.  

  • Security vulnerabilities - Like all apps, mobile health apps can contain security flaws that hackers exploit to access stored data. Several fitness apps have been found leaking user data online.  

  • Lack of HIPAA compliance - Many health apps don't store data in a HIPAA compliant manner or allow users to request records. This limits patient control over private medical information.  

  • Unauthorized access - Apps may allow access to data even when a phone is locked. Anyone gaining physical access to the device could view sensitive health information.


Patients should scrutinize app privacy policies, limit data sharing, and enable security features like app passcodes. More regulation may be needed around health apps to ensure adequate privacy safeguards are in place.


Wearable Devices

Wearable health devices like Fitbits, Apple Watches, and glucose monitors are growing in popularity. These devices can track steps, heart rate, sleep patterns, blood pressure, blood glucose levels, and more. While wearables provide convenience for patients to monitor their own health data, they also raise privacy concerns. 


Wearable devices connect to phones and cloud services to sync data. If these services are hacked, sensitive health information could be stolen. The small size of wearables also makes them easy to lose or misplace, risking physical access to stored data. Manufacturers of wearable devices need stringent security protocols to encrypt data and prevent breaches. 


Some medical wearables like pacemakers and insulin pumps are implanted inside patients' bodies. These devices are vulnerable to cyberattacks that could threaten patients' safety. Security researchers have already demonstrated the ability to hack some medical wearables, underscoring the need for improved safeguards. 


Patients must weigh the benefits of accessing their own health data through wearable devices versus potential privacy risks. Manufacturers have a responsibility to implement safety features and encryption to keep patients' data secure. More oversight may be needed to regulate and audit the security of medical wearable devices.


Genetic Testing


Genetic testing has become increasingly popular and accessible to consumers in recent years. Direct-to-consumer genetic testing companies like 23andMe and Ancestry allow people to purchase at-home test kits, submit DNA samples, and receive personalized reports about their genetic ancestry and health risks. While this expanded access provides benefits, it also raises privacy concerns.


When consumers use direct-to-consumer genetic tests, their genetic data is collected, analyzed, and stored by the testing companies. There are questions about how this sensitive information is secured and shared. Some companies have proprietary rights to their customers' genetic data and can sell or share it with third parties for research and product development. Customers may not fully understand or consent to these secondary uses.

There are also concerns that genetic data could be hacked or leaked. As testing databases grow, they become increasingly valuable targets for cybercriminals. If a bad actor gained access, customers' genetic codes and health profiles could be stolen and exploited. Discrimination based on pre-existing conditions or genetic diseases is another potential risk if private data was compromised.


Strong data privacy regulations like HIPAA and GINA provide some safeguards for consumers in the US. However, policies and enforcement remain uneven. More transparency from testing companies and proactive protections are needed to fully secure customers' sensitive genetic information. Consumers should research companies' data policies before submitting their DNA. While convenience is appealing, individuals must weigh benefits against potential privacy risks.


Telehealth Services

The rise of telehealth services during the COVID-19 pandemic has allowed patients to access healthcare from the comfort of their homes. However, telehealth also presents new privacy challenges that patients and providers must consider.


When using telehealth services, sensitive patient information is transmitted and stored digitally. This includes health history details, audio/video of patient appointments, and more. If not properly secured, this data could be vulnerable to cyberattacks or unauthorized access.


Providers offering telehealth must take steps to encrypt data and communications. Strong authentication methods should be used to verify patient identities. Policies need to be in place for where telehealth data is stored, who can access it, and how long it is retained.

Patients using telehealth services should inquire about the platform's privacy safeguards before sharing personal information. Only use telehealth through trusted providers who can demonstrate compliance with healthcare privacy laws. Be cautious of telehealth apps that do not clearly explain how they protect user data.


As telehealth continues to evolve, regulators will need to develop frameworks that balance innovation and privacy. Organizations like the U.S. Department of Health and Human Services (HHS) may issue new telehealth privacy guidelines for providers to follow. Patients must also educate themselves on privacy risks and exercise caution when seeking care through online platforms. With vigilance from all parties, telehealth can fulfill its promise of convenient care while still upholding patient privacy.


Cloud Storage


Storing patient health records in the cloud can offer benefits like easier access and collaboration between providers. However, it also comes with vulnerabilities that patients should be aware of. When health data is stored by third-party cloud providers, the patient has less control over the security of their private medical information. 


Some concerns with cloud storage of health data include:


  • Data breaches - Cloud servers can be targets for hacking attempts and malware. A breach could expose sensitive health records.  

  • Unauthorized access - Cloud provider employees may have the ability to view patient data. There should be safeguards to prevent abuse.  

  • Geo-location of data - When data is stored in the cloud, patients may not know exactly where their data is located geographically. Different locations have varying laws and regulations.  

  • Data availability - If a cloud provider has an outage, health records could become temporarily inaccessible. This could impede urgent care.  

  • Long-term viability - If a cloud provider goes out of business, patients could lose access to their data. Proper export and backups are essential.


Patients should inquire about the specific security measures that cloud providers implement before agreeing to have their health information stored in the cloud. Understanding the risks allows patients to make informed decisions about the privacy tradeoffs involved with digital health data.

The emergence of blockchain technology presents promising opportunities to better secure patient health data. A blockchain is a decentralized, distributed ledger that records transactions in a verifiable and permanent way.


Blockchain technology allows for secure sharing of medical data between healthcare providers, while maintaining patient privacy. Each participant in the network has their own encrypted copy of the ledger. Any updates or changes are synchronized across all copies in real-time. This makes tampering with or hacking data extremely difficult.


One major advantage of blockchain for healthcare is the ability to authorized different levels of access control. Patients can grant access to their medical records to specific providers, for limited time periods. This prevents the exposure of sensitive health data to those without permission.


Blockchain also enables patients to be stewards of their own medical data. Rather than health records being stored in multiple siloed databases, patients could control their comprehensive health history in a personal blockchain wallet. They could then provide direct access to healthcare providers when required.


The immutable nature of blockchain ledgers also creates detailed audit trails. Any access or changes to a patient's medical history would be time-stamped and verifiable. This improves overall accountability and data integrity.


While there are regulatory and adoption hurdles, blockchain technology shows much promise for healthcare data security. Solutions built on blockchain can empower patients with ownership over their medical records, while enabling secure data sharing between providers. Implementing blockchain solutions has the potential to greatly strengthen patient privacy and enhance data security.
