Data Privacy Compliance During Integration.
Data Privacy Compliance During Integration
When two or more systems, databases, or organizations merge or integrate, data privacy compliance becomes critical. This is because integration often involves transferring, processing, or combining personal or sensitive data, potentially across jurisdictions. Non-compliance can lead to legal, financial, and reputational consequences.
1. Key Principles for Compliance
Data privacy compliance during integration revolves around several principles:
Lawful Basis for Data Processing
Organizations must ensure that any data transferred or combined during integration has a lawful basis under relevant data protection laws (e.g., GDPR, CCPA).
Example: Consent must be obtained, or legitimate interest must be clearly defined.
Purpose Limitation
Data should only be used for the purpose for which it was originally collected unless additional consent is obtained.
Data Minimization
Only the data necessary for the integration should be collected or transferred.
Security Measures
Strong technical and organizational measures (encryption, access controls, anonymization) must protect data during integration.
Cross-Border Data Transfers
When data crosses jurisdictions, laws like GDPR’s Chapter V rules must be followed, including Standard Contractual Clauses (SCCs) or binding corporate rules (BCRs).
Transparency and Accountability
Data subjects should be informed about the integration and their rights maintained.
2. Steps for Privacy Compliance During Integration
Conduct Data Mapping & Audit
Identify which personal data is involved, its source, and how it will be processed.
Perform Data Protection Impact Assessment (DPIA)
Evaluate risks to individuals’ rights and take mitigating actions.
Review Contracts & Third-Party Agreements
Ensure all partners follow compliance obligations.
Implement Privacy by Design
Integrate privacy measures into systems architecture, not as an afterthought.
Obtain Necessary Consents
For new purposes, update privacy notices and secure consent if required.
Monitor & Audit
Continuously review compliance during and after integration.
3. Notable Case Laws Illustrating Compliance Issues
Case 1: Google Spain SL, Google Inc. v Agencia Española de Protección de Datos (2014) (CJEU)
Key Issue: Right to be forgotten during data processing.
Relevance: When integrating data, organizations must allow deletion requests and respect privacy rights even if the data comes from multiple sources.
Case 2: Schrems II (Data Protection Commissioner v Facebook Ireland and Maximillian Schrems, 2020)
Key Issue: Transfer of personal data from the EU to the US under Privacy Shield.
Relevance: Cross-border integrations must comply with international data transfer rules; invalidating Privacy Shield impacted many integrations.
Case 3: UK Information Commissioner v TalkTalk Telecom Group Ltd (2015)
Key Issue: Data breach due to inadequate security.
Relevance: Integration requires robust cybersecurity measures; negligent integration can trigger heavy penalties.
Case 4: Facebook, Inc. v. Australian Competition and Consumer Commission (2020)
Key Issue: Misuse of personal data without proper disclosure.
Relevance: During mergers or system integrations, organizations must ensure full transparency to users about new data flows.
Case 5: In re Marriott International, Inc. Customer Data Security Breach Litigation (2019, USA)
Key Issue: Personal data from Starwood integration exposed due to breach.
Relevance: Highlights risks of integrating legacy systems with insufficient security; proper due diligence is critical.
Case 6: ICICI Bank Ltd v. State of Maharashtra (India, 2018)
Key Issue: Unauthorized sharing of customer data during system upgrade.
Relevance: Demonstrates importance of compliance with national privacy regulations during integration; banks must secure consent and maintain data confidentiality.
4. Lessons from Case Laws
Always secure consent if the purpose of processing changes.
Perform thorough security audits before merging databases.
Monitor cross-border transfers carefully; not all frameworks (like Privacy Shield) are valid.
Respect data subject rights (access, deletion, correction).
Transparency is mandatory in communicating how data will be used post-integration.
5. Practical Compliance Checklist
