Brand Protection and KVKK: How Can Data Privacy Be Ensured in Product Verification?

Data Privacy • KVKK • Brand Protection

Product origin verification systems play a critical role in combating counterfeiting while also creating new responsibilities for personal data security. Under KVKK, Türkiye’s Personal Data Protection Law, brands must process customer data collected during verification in a minimal, anonymous and secure manner.

1. Data Flows in Product Verification Systems

When a customer scans a product’s QR or NFC code, the system may collect:

📍 Geographic location: based on IP or GPS
📱 Device type and browser information
⏱️ Timestamp
🧾 Verification result: genuine / counterfeit / suspicious

Although not every item individually constitutes personal data under KVKK, combining them can make an individual identifiable. The guiding principle should therefore be data minimisation.

“Verification should be secure, but should not become a means of tracking the user.”

2. Fundamental Principles Under KVKK

Principle	Description	Implementation
Data minimisation	No more data than necessary should be collected	Location should be processed only at country/region level
Anonymisation	Personal data is de-identified	IP addresses should be stored as hashes
Explicit consent	The user’s informed approval	Display consent wording on the verification page
Data security	Prevent unauthorised access	Data transmission over SSL/TLS 1.3

3. Anonymising Customer Data

IP Hashing: Anonymising IP addresses with SHA-256 makes retrospective identification impossible.
UUID Tokenization: Each verification session receives a random identity, without association with a real user.
Data Lifecycle Management: All verification logs are automatically deleted after 30 days or moved to an anonymous archive.

Technical recommendation: Instead of retaining user data, retain only the verification transaction’s hash result (e.g. “verification_hash”).

4. Balancing KVKK and Brand Protection

Brands generally want to collect more data to improve product security. Under KVKK, however, this may be considered excessive processing. The right balance is:

🔍 The minimum data necessary for verification
📉 Anonymous reporting that does not identify individuals
📜 Transparent privacy notices

“Protecting data is an extension of protecting reputation.”

5. Data Processing Policy: A Transparency Standard

Core KVKK information to include in verification systems:

Data controller and contact information
Processing purpose: “Product verification and counterfeit detection”
Data retention period and destruction policy
International transfers: for example, CDNs or global verification APIs
User rights: access, rectification, erasure, etc.

B10 LegalSync™ infrastructure adds an automatic KVKK compliance layer to brand verification systems, dynamically updating privacy notices and processing records.

6. International Data Transfer Risks

Verification systems generally run on global infrastructure such as Cloudflare, AWS or Google Cloud, creating a risk of international data transfers. In these cases:

Transferred data should be anonymised,
Data processing agreements (DPAs) and EU Standard Contractual Clauses (SCCs) should be followed,
Explicit consent or safe-country criteria compliant with Article 9 of KVKK should be satisfied.

7. Automated Compliance Auditing

AI Audit: Analyses KVKK logs to detect unnecessary data fields.
Consent Tracker: Stores users’ consent preferences by version.
Data Purge Scheduler: Automatically deletes personal data at the end of the specified period.

“Data privacy is the invisible side of brand security.”

Make your verification systems fully compliant with KVKK.
B10 CounterShield™ and LegalSync™ strike the ideal balance between product security and data privacy, protecting your brand’s reputation and legal integrity.
