The General Data Protection Regulation (GDPR) is a landmark data privacy law that governs how businesses and organizations handle personal data of individuals within the European Union (EU). Since its enforcement in May 2018, GDPR has significantly influenced the way businesses collect, process, and store data. Understanding data processing under GDPR is crucial for compliance, particularly in industries handling large amounts of personal information.
In this article, we will explore two concrete examples of data processing under GDPR. These examples will illustrate how businesses must handle data responsibly while ensuring compliance with GDPR’s core principles, such as transparency, accountability, and lawful processing.
What is Data Processing Under GDPR?
Under GDPR, data processing refers to any operation performed on personal data, whether automated or manual. This includes collection, storage, alteration, retrieval, use, disclosure, or deletion of personal data. Personal data encompasses any information related to an identifiable individual, such as names, email addresses, phone numbers, or IP addresses.
GDPR distinguishes between data controllers (who determine the purpose and means of processing) and data processors (who process data on behalf of the controller). Both entities must adhere to GDPR rules, ensuring that data subjects’ rights are upheld.
Example 1: E-commerce Website Handling Customer Data
Scenario
A popular e-commerce store, ShopX, collects and processes customer data for various purposes, including order fulfillment, customer service, and marketing. The company must ensure that its data processing activities comply with GDPR.
Data Processing Activities Involved
- Customer Account Creation
- When a customer signs up on ShopX, they provide personal details such as their name, email address, phone number, and shipping address.
- GDPR Considerations:
- ShopX must obtain explicit consent for processing this data.
- The company must have a clear and transparent privacy policy explaining how this data will be used.
- Order Processing & Payment
- To fulfill an order, ShopX processes payment details via a third-party payment processor.
- GDPR Considerations:
- ShopX must ensure that its payment provider is GDPR-compliant and that there is a data processing agreement (DPA) in place.
- Customer data should be processed only for the purpose of completing the transaction.
- Marketing and Advertising
- ShopX uses email marketing to send promotional offers to customers.
- GDPR Considerations:
- Customers must opt-in to receive marketing communications.
- ShopX must provide a clear unsubscribe option in every email.
- Data Retention and Deletion
- Customer data is retained for a specified period after order fulfillment.
- GDPR Considerations:
- ShopX must define a data retention policy and ensure that data is deleted after its intended use.
- Customers must have the right to request data deletion (right to be forgotten).
How ShopX Ensures GDPR Compliance
✅ Legal Basis for Processing: ShopX justifies data processing through contractual necessity (order fulfillment), consent (marketing), and legitimate interest (fraud prevention).
✅ Data Protection Measures: The company uses encryption and access controls to secure sensitive customer data.
✅ Data Subject Rights: Customers can access, modify, or delete their personal data via their account settings.
✅ Third-Party Compliance: The e-commerce platform only works with GDPR-compliant vendors for payment processing and marketing.
This example illustrates how an e-commerce store processes personal data while ensuring compliance with GDPR principles.
Example 2: Employee Data Processing in an HR System
Scenario
A multinational corporation, TechCorp, processes employee data for human resources (HR) purposes, such as payroll, performance evaluation, and employee benefits. The company operates in multiple EU countries and must comply with GDPR when handling employee information.
Data Processing Activities Involved
- Recruitment & Onboarding
- During the hiring process, TechCorp collects resumes, contact details, employment history, and references.
- GDPR Considerations:
- Job applicants must be informed about how their data will be processed.
- Data should be retained only for a specified period if the applicant is not hired.
- Payroll Processing
- Employee bank details, salary information, and tax identification numbers are processed for payroll.
- GDPR Considerations:
- The legal basis for processing is contractual obligation, as payroll is essential for employment.
- Access controls and encryption should be in place to secure financial data.
- Performance Evaluations & HR Records
- Employees’ performance data is stored for internal reviews and promotions.
- GDPR Considerations:
- Employees must be informed about how performance data will be used.
- There must be a legitimate interest or contractual necessity for processing.
- Data Sharing with Third Parties
- Employee data may be shared with third-party service providers, such as health insurance providers or pension schemes.
- GDPR Considerations:
- Third parties must sign a data processing agreement (DPA) with TechCorp.
- Employees should be informed if their data is shared externally.
- Employee Right to Access and Deletion Requests
- Employees can request access to their personal data or request corrections.
- GDPR Considerations:
- The company must respond to data access requests within one month.
- Employees have the right to rectification if their data is incorrect.
Example 3: Healthcare Clinic Processing Patient Data
Scenario
A private healthcare clinic, MedCare, offers medical consultations and diagnostic services. Since MedCare processes sensitive personal data, including medical history and patient health records, GDPR imposes strict requirements on data protection.
Data Processing Activities Involved
- Patient Registration & Medical History Collection
- New patients must provide their name, contact details, medical history, and insurance information.
- GDPR Considerations:
- MedCare must obtain explicit consent from patients before collecting their medical data.
- Patients must be informed about how their data will be used via a clear privacy notice.
- Appointment Scheduling & Reminders
- MedCare uses an online system to schedule appointments and send reminders via SMS or email.
- GDPR Considerations:
- Patients must opt-in for reminders, and the system must provide an option to unsubscribe.
- Data must be processed only for appointment management and not used for marketing without explicit consent.
- Storing Medical Records
- Patient health records are stored digitally in a secure electronic medical record (EMR) system.
- GDPR Considerations:
- Medical records must be encrypted and access-controlled, ensuring only authorized personnel can access them.
- MedCare must implement data minimization—only collecting and storing the necessary information.
- Sharing Patient Data with Third Parties
- MedCare may share patient data with insurance companies or external specialists for referrals.
- GDPR Considerations:
- Patients must be informed before their data is shared and give explicit consent.
- Third parties must sign a Data Processing Agreement (DPA) to ensure compliance.
- Right to Access & Deletion
- Patients can request access to their medical records or request corrections.
- GDPR Considerations:
- MedCare must provide patients with easy access to their data within one month of the request.
- Certain medical records cannot be deleted due to legal retention requirements, but MedCare must inform patients of this limitation.
How MedCare Ensures GDPR Compliance
✅ Explicit consent is obtained before processing medical data.
✅ Secure data storage, including encryption and restricted access.
