GDPR-Focused Security & Compliance Whitepaper (EU / Germany)

Document Version: 1.0 (GDPR Edition)
Applicable Jurisdiction: European Union / Germany
System: Farm Management Platform -- Camera Snapshot Webhook Integration

This document describes how the Farm Management Platform processes camera snapshot data in a manner aligned with:

• Regulation (EU) 2016/679 (GDPR)
• German Federal Data Protection Act (BDSG)
• General EU data protection best practices

It is intended for:

• Data Protection Officers (DPOs)
• IT Security Auditors
• Compliance Departments
• Enterprise Customers

2. Role Definition Under GDPR

2.1 Data Controller

The customer operating the farm and configuring camera capture is the Data Controller under Art. 4(7) GDPR.

The customer determines:

• Purpose of camera usage
• Capture frequency
• Image resolution
• Retention duration
• Recipients (webhook configuration)

2.2 Platform Provider

The Farm Management Platform acts as:

• Data Processor under Art. 4(8) GDPR
• Processing limited to documented customer instructions

No independent profiling or secondary processing is performed.

The system processes:

• Periodic still images (JPEG format)
• Camera identifier
• Timestamp metadata

Potential personal data: - Identifiable persons in images - Vehicle license plates - Employee activity - Visitors

The platform does not process biometric data or perform facial recognition.

The lawful basis for camera image processing must be determined by the customer (Controller), typically:

• Art. 6(1)(f) -- Legitimate interest (e.g., security, operational monitoring)
• Art. 6(1)(b) -- Contract performance (limited use cases)
• Art. 6(1)(c) -- Legal obligation (rare cases)

The platform does not determine the lawful basis.

The system supports data minimization through:

• Still-image transmission only (no continuous streaming)
• Configurable capture interval
• Adjustable resolution
• Optional local-only preview

Customers are encouraged to:

• Use lowest resolution necessary
• Limit capture frequency
• Avoid capturing public areas unnecessarily

6. Integrity & Confidentiality (Art. 5(1)(f))

6.1 Transport Security

• HTTPS enforced (TLS 1.2+)
• Strong cipher suites
• Certificate validation required

6.2 Cryptographic Authentication

Each camera upload uses:

HMAC-SHA256 signature with unique per-camera secret

Protection includes:

• Message integrity
• Authenticity verification
• Replay attack prevention
• Secret never transmitted in plaintext

6.3 Access Control

• Role-based permissions
• Strong password policy
• Optional Multi-Factor Authentication
• Session expiration and secure cookies

The platform allows configurable retention policies.

Customers can:

• Define automatic deletion periods
• Manually delete stored snapshots
• Disable storage entirely if desired

No indefinite retention occurs by default.

The system supports controller obligations for:

• Right of access
• Right to erasure
• Right to restriction of processing
• Right to objection

Since the customer is the Controller, they are responsible for fulfilling data subject requests.

The platform provides tools to:

• Locate stored images by date/camera
• Delete specific records
• Export records if required

The system maintains logs for:

• Webhook creation
• Webhook modification
• Secret rotation
• Administrative actions

Logs contain:

• Timestamp
• User ID
• Source IP address

This supports accountability obligations under GDPR.

Technical and organizational measures (TOMs):

• Encrypted transport (TLS)
• HMAC request authentication
• Rate limiting and abuse prevention
• Maximum upload size restrictions
• Input validation
• Secure coding practices
• Regular dependency updates

Risk-based approach applied according to:

• Nature of data (potential personal data in images)
• Volume (periodic still images only)
• Sensitivity (no biometric processing)

The platform hosting environment must be documented separately.

If hosted within the EU:

• No third-country transfer occurs.

If hosted outside the EU:

• Standard Contractual Clauses (SCCs) must apply.
• Additional safeguards assessed per Schrems II guidance.

Any infrastructure provider (e.g., hosting provider) acts as subprocessor under Art. 28 GDPR.

A Data Processing Agreement (DPA) should:

• Define processing scope
• Define security measures
• Define breach notification obligations

In case of a security incident:

• Customers are notified without undue delay
• Incident details documented
• Risk assessment performed
• Cooperation provided for supervisory authority notification

The system design incorporates:

• Minimal data collection (still images only)
• No default external forwarding
• Transparent webhook visibility
• Optional retention configuration
• No hidden tracking mechanisms

Webhook destinations are visible and auditable.

Primary Risks: - Unauthorized admin access - Misconfiguration of webhook destination - Excessive retention period

Mitigations: - Strong authentication - Audit logging - Role restrictions - Cryptographic request signing - Retention controls

Residual risk level: Moderate and proportionate to operational monitoring use cases.

Customers must:

• Establish lawful basis
• Inform affected individuals where required
• Display camera signage where applicable
• Define retention policy
• Conclude DPA with platform provider
• Perform Data Protection Impact Assessment (DPIA) if required

The Farm Camera Snapshot Integration is designed to align with GDPR principles through:

• Secure transmission
• Cryptographic integrity protection
• Data minimization
• Audit logging
• Configurable retention
• Clear controller-processor separation

Final compliance responsibility remains with the Controller (customer), as required under GDPR.
