AI Vendor Privacy Due Diligence

Overview

AI services create complex controller-processor relationships that differ significantly from traditional data processing arrangements. Whether an AI vendor is a processor, joint controller, or independent controller depends on the degree of autonomy the vendor has over personal data processing — particularly regarding model training on customer data, data retention for model improvement, and the vendor's independent purposes for the data. This skill provides the framework for determining controller-processor roles in AI service relationships, conducting privacy due diligence on AI vendors, and establishing appropriate contractual protections.

Controller-Processor Determination for AI

Decision Framework

AI Service Model	Typical Role	Key Factors	GDPR Article
SaaS AI — Customer data processed per instructions	Vendor = Processor	Vendor processes data solely on controller's instructions; no independent use	Art. 28 DPA required
SaaS AI — Customer data used for model training	Vendor = Joint Controller or Independent Controller	Vendor uses customer data for own model improvement beyond contracted service	Art. 26 JCA or separate controller notice
Embedded AI — Pre-trained model in customer infrastructure	Customer = Controller; Vendor = may be processor for support	Model runs in customer environment; vendor may access data for support/updates	Art. 28 if vendor accesses data
API-based AI — Customer sends data for inference	Vendor = Processor (if no data retention) or Joint Controller (if training on inputs)	Depends on whether vendor retains, uses, or trains on input data	Assessment required
AI Platform — Customer builds models on vendor platform	Vendor = Processor for infrastructure; Controller for platform data	Vendor provides compute; customer controls data and model	Art. 28 DPA + audit rights
AI Marketplace — Pre-built models with customer data	Depends on data flow	If customer data enters vendor model → joint controller assessment	Case-by-case

Key Determination Questions

Who determines the purpose of processing? — The entity deciding why personal data is processed
Who determines the means of processing? — The entity deciding how data is processed (but "non-essential means" may be delegated to processor)
Does the vendor use data for its own purposes? — Model training, benchmarking, product improvement using customer data
Does the vendor retain data beyond service delivery? — Data kept after inference, stored for training, retained in logs
Does the vendor make independent decisions about the data? — Choosing to train models, sharing with sub-processors not instructed by customer

Common AI Vendor Patterns

Pattern 1: Pure Inference API (Vendor = Processor)

Customer sends data; receives inference result
Vendor does not retain input data beyond processing
Vendor does not train on customer data
Vendor acts solely on customer's instructions
Contractual: Art. 28 DPA with clear scope

Pattern 2: AI with Model Improvement (Vendor = Joint Controller)

Customer sends data; receives inference result
Vendor retains data to improve its models
Vendor determines that model training is a purpose
Both parties benefit from the model improvement
Contractual: Art. 26 Joint Controller Agreement

Pattern 3: AI with Anonymised Analytics (Assessment Required)

Customer sends data; receives inference result
Vendor claims to anonymise data and use aggregated analytics
If anonymisation is effective: no personal data processing for analytics
If anonymisation is not effective (re-identification possible): vendor is controller for analytics
Assessment: Verify anonymisation effectiveness per WP216

Pattern 4: Embedded AI with Telemetry (Vendor = Processor + may be Controller)

AI model runs in customer environment
Vendor collects telemetry data including model performance
If telemetry contains personal data: vendor may be controller for telemetry processing
Contractual: Art. 28 DPA for model support + separate arrangement for telemetry

Due Diligence Assessment Framework

Phase 1: Vendor AI Processing Inventory

For each AI vendor, document:

Element	Documentation Required
AI capabilities	What AI functions does the vendor provide?
Personal data inputs	What personal data is sent to the vendor?
Personal data outputs	What personal data does the vendor return?
Data retention	Does the vendor retain input data? For how long?
Model training	Does the vendor train on customer data?
Sub-processors	Does the vendor use sub-processors for AI processing? Where?
Data location	Where is AI processing performed? What jurisdictions?
Security measures	What security controls protect data during AI processing?
Human review	Does vendor personnel access customer data?

Phase 2: Privacy Risk Assessment

Risk Factor	Assessment	Risk Level
Data sensitivity	Special category data sent to AI vendor?
Data volume	Volume of personal data processed by vendor
Vendor data use	Vendor uses customer data for own purposes?
International transfers	Data processed outside EU/EEA?
Sub-processor chain	Number and location of sub-processors
Security posture	Certifications (ISO 27001, SOC 2)?
Incident history	Prior data breaches or enforcement actions?
AI-specific risks	Model memorization, output leakage, bias?

Phase 3: Contractual Assessment

Contractual Element	Required?	Status
Art. 28 DPA or Art. 26 JCA	Yes
Processing scope and purpose limitation	Yes
Prohibition on data use beyond instructions (if processor)	Yes
Model training opt-out	Yes (if vendor trains on data)
Sub-processor notification and approval	Yes
International transfer safeguards	If applicable
Data deletion on termination	Yes
Audit rights	Yes
Breach notification obligations	Yes
AI-specific: model privacy testing	Recommended
AI-specific: bias assessment obligations	Recommended for high-risk
AI-specific: output accuracy warranties	Recommended

AI-Specific Contractual Clauses

Model Training Restrictions

The Processor shall not use Customer Data to train, improve, fine-tune, or
otherwise develop any machine learning model, algorithm, or AI system,
whether for the Customer's benefit or for any other purpose, without prior
written consent from the Customer. Any consent granted shall specify the
scope of permitted training, the data categories involved, and the privacy
safeguards to be applied.

AI Output Accuracy

The Provider acknowledges that AI system outputs about identifiable data
subjects must comply with the accuracy principle under Art. 5(1)(d) GDPR.
The Provider shall implement measures to minimise inaccurate outputs about
data subjects and shall promptly correct inaccurate outputs upon
notification.

Model Privacy and Bias Obligations

The Provider shall conduct periodic privacy audits of AI models processing
Customer Data, including membership inference testing and training data
extraction testing, and shall make results available to the Customer upon
request. The Provider shall monitor AI systems for discriminatory outcomes
and shall implement bias mitigation measures as required.

Enforcement Relevance

EDPB Guidelines 07/2020 on Controller-Processor: Determination depends on factual circumstances, not contractual labels. A vendor labelled "processor" that uses data for its own purposes is factually a controller.
Garante v. OpenAI (2023): OpenAI's role as controller for ChatGPT training data confirmed — processing personal data for model training is an independent controller purpose.
CJEU C-40/17 (Fashion ID): Joint controller status can arise when a party has influence over the purpose and means of processing, even without access to the data.
DPC v. Meta (WhatsApp, 2023): EUR 5.5M fine — processor-controller determination must reflect actual data use, not just contractual terms.

Integration Points

ai-dpia: Vendor AI processing must be included in DPIA scope
ai-training-lawfulness: Vendor training on customer data requires lawful basis assessment
ai-transparency-reqs: Data subjects must be informed about AI vendor processing
ai-deployment-checklist: Vendor due diligence is a pre-deployment checklist item
