The General Data Protection Regulation (GDPR) is a comprehensive data protection law implemented by the European Union (EU) to safeguard the privacy and personal data of individuals. One of its key components is the classification of sensitive personal data, which requires stringent protection due to its potential to harm individuals if misused. Sensitive data includes details related to health, biometrics, racial or ethnic origin, religious beliefs, political opinions, genetic data, and sexual orientation, among others.
To better understand the significance of GDPR compliance, this article explores two real-world examples of GDPR-sensitive data: health data in the healthcare industry and biometric data in workplace security.
Example 1: Healthcare Data Breach in a Medical Institution
The Scenario
A large private hospital in Germany stored patient health records, including medical history, prescriptions, and test results, on an unsecured server. Due to an internal misconfiguration, thousands of these records were left accessible to unauthorized individuals. Hackers exploited this vulnerability, leading to a massive data breach.
GDPR Compliance Issues
Under GDPR, health data is classified as special category data, meaning it requires heightened protection. The breach in this case resulted in multiple violations of GDPR regulations:
- Failure to Implement Adequate Security Measures – Article 32 of GDPR requires organizations to implement appropriate technical and organizational measures to protect personal data. The hospital failed to properly secure patient records.
- Lack of Data Encryption – Health data should be encrypted to prevent unauthorized access. In this case, patient records were stored in plaintext, making them easily readable.
- Delayed Breach Notification – GDPR mandates that organizations report data breaches to authorities within 72 hours. The hospital took two weeks to disclose the breach, violating Article 33.
Consequences
The data breach resulted in significant legal and financial repercussions for the hospital:
- The Data Protection Authority (DPA) fined the institution €5 million for failing to safeguard patient records adequately.
- Affected patients filed lawsuits, demanding compensation for their compromised medical history.
- The hospital’s reputation suffered, leading to a decline in patient trust and potential revenue loss.
Lessons Learned
Organizations dealing with health data must:
- Encrypt sensitive records and store them in a secure database.
- Implement multi-layered security measures to prevent unauthorized access.
- Develop a robust breach notification process to comply with GDPR reporting timelines.
Example 2: Biometric Data Misuse in Workplace Security
The Scenario
A multinational company implemented a biometric time-tracking system that required employees to scan their fingerprints for attendance monitoring. However, employees were not properly informed about the purpose and legal basis for collecting their biometric data, nor were they given the option to opt out. Additionally, the company stored fingerprint scans without adequate security, making them vulnerable to cyberattacks.
GDPR Compliance Issues
Biometric data falls under special category data according to GDPR. The company’s practices violated several key GDPR provisions:
- Failure to Obtain Explicit Consent – Article 9 of GDPR states that organizations must obtain explicit consent before collecting biometric data. The company did not provide employees with a clear choice or adequate information.
- Unlawful Processing of Data – Employers must demonstrate a legitimate legal basis for processing biometric data. In this case, the company did not establish a valid reason beyond convenience.
- Inadequate Data Security Measures – Biometric data must be hashed or encrypted to prevent theft. The company stored raw fingerprint data, making it easy for hackers to misuse.
Consequences
- The company was fined €1.2 million by the regulatory authorities for improper data handling.
- Employees took legal action, citing invasion of privacy and lack of informed consent.
- The company had to discontinue the biometric system and revert to non-invasive attendance tracking methods.
Lessons Learned
Companies using biometric data should:
- Obtain clear and explicit consent before collecting sensitive biometric data.
- Implement stringent security measures, such as encryption and hashing.
- Offer employees an alternative method to ensure data processing remains voluntary.

- Implement multi-layered security measures to prevent unauthorized access.
- Develop a robust breach notification process to comply with GDPR reporting timelines.
Example 4: Biometric Data Misuse in Workplace Security
The Scenario
A multinational company implemented a biometric time-tracking system that required employees to scan their fingerprints for attendance monitoring. However, employees were not properly informed about the purpose and legal basis for collecting their biometric data, nor were they given the option to opt out. Additionally, the company stored fingerprint scans without adequate security, making them vulnerable to cyberattacks.
GDPR Compliance Issues
Biometric data falls under special category data according to GDPR. The company’s practices violated several key GDPR provisions:
- Failure to Obtain Explicit Consent – Article 9 of GDPR states that organizations must obtain explicit consent before collecting biometric data. The company did not provide employees with a clear choice or adequate information.
- Unlawful Processing of Data – Employers must demonstrate a legitimate legal basis for processing biometric data. In this case, the company did not establish a valid reason beyond convenience.

- Employees took legal action, citing invasion of privacy and lack of informed consent.
- The company had to discontinue the biometric system and revert to non-invasive attendance tracking methods.
Lessons Learned
Companies using biometric data should:
- Obtain clear and explicit consent before collecting sensitive biometric data.
- Implement stringent security measures, such as encryption and hashing.
- Offer employees an alternative method to ensure data processing remains voluntary.
Example 5: Financial Data Exposure by an Online Retailer
The Scenario
A major European online retailer suffered a data breach when hackers gained access to credit card details, billing addresses, and purchase histories of over 250,000 customers. The breach occurred due to poor security measures in the company’s payment processing system, which stored unencrypted credit card information in a centralized database.
GDPR Compliance Issues
Financial data is highly sensitive, and GDPR mandates strict security measures:
- Failure to Use Data Minimization Techniques – Under Article 5(1)(c), organizations must limit the storage of personal data to what is strictly necessary. The retailer stored complete credit card details instead of encrypted tokens, violating GDPR guidelines.
- Lack of Encryption – GDPR Article 32 mandates the use of encryption to protect sensitive data. The company failed to encrypt stored credit card details, leading to unauthorized access.
- Delayed Breach Notification – According to Article 33, organizations must notify regulators within 72 hours of a breach. The company took over three weeks to disclose the incident, further compounding its non-compliance.
Consequences
- The retailer was fined €8 million for GDPR violations.
- Customers affected by identity theft filed lawsuits against the company.
- The company had to implement PCI DSS-compliant encryption and improve its cybersecurity measures.
Lessons Learned
- Encrypt and tokenize financial data to prevent exposure.
- Regularly audit security systems to identify vulnerabilities.
- Train employees on data breach response protocols.
Example 6: Racial Profiling in Targeted Advertising
The Scenario
A digital marketing agency partnered with a real estate firm to deliver targeted housing advertisements based on ethnic background and nationality. The company used AI algorithms that categorized users by racial and ethnic characteristics inferred from their browsing habits and online activity. As a result, certain minority groups were excluded from seeing housing advertisements.
GDPR Compliance Issues
- Illegal Processing of Special Category Data – According to Article 9, processing sensitive data (including racial and ethnic origin) requires explicit consent from individuals. The marketing agency did not obtain this consent.
- Discriminatory Practices – GDPR enforces the principle of fair processing (Article 5), ensuring that data use does not result in discrimination. The company’s AI system disproportionately disadvantaged minority groups, leading to unfair treatment.
- Failure to Conduct a Data Protection Impact Assessment (DPIA) – Under Article 35, organizations must conduct a DPIA when processing data that could result in high risks to individuals’ rights. The company neglected this requirement.
Consequences
- The company was fined €2.5 million by the EU’s Data Protection Authority.
- Consumer rights organizations sued the real estate firm for discriminatory advertising practices.
- The company had to modify its AI algorithms and conduct bias audits before running future targeted ad campaigns.
Lessons Learned
- Avoid processing racial or ethnic data without explicit user consent.
- Implement AI fairness checks to prevent biased targeting.
- Conduct Data Protection Impact Assessments (DPIAs) when handling sensitive user data.
Conclusion
The GDPR provides a strict framework for handling sensitive personal data, and failure to comply can result in severe penalties, reputational damage, and legal consequences. The healthcare industry and workplace security are just two of many areas where sensitive data breaches can occur. Organizations must prioritize data protection strategies, employee training, and security protocols to ensure GDPR compliance and protect individuals’ rights.
