Data Privacy in AI: GDPR, PII Redaction, and ISO 27001 for Training Data
AI training data is full of privacy landmines — names in text, faces in images, voices in audio.
The Privacy Problem in AI Training Data
Training data collected from real-world sources inevitably contains personally identifiable information (PII). Using this data without proper redaction exposes organisations to regulatory penalties and reputational damage.
PII in Text: Names, Addresses, Phone Numbers, ID Numbers
Text datasets may contain names, email addresses, phone numbers, national ID numbers, financial account numbers, and medical record identifiers. Automated NER-based detection combined with human review is the standard approach.
PII in Audio: Voice Biometrics and Speaker Identification
Voices are biometric identifiers. Audio datasets must remove or pseudonymise speaker-identifying information and obtain proper consent from all contributors.
PII in Images: Face Blurring and License Plate Redaction
Computer vision datasets must blur faces and license plates before annotation and use. Automated detection with human verification is the minimum standard.
GDPR Requirements for AI Training Data
GDPR requires lawful basis for processing personal data used in training (typically consent or legitimate interest), data minimisation, purpose limitation, and the right to erasure.
Consent Management for Data Collection Contributors
All data contributors must provide informed consent for their data to be used in AI training. Consent must be specific, documented, and revocable.
ISO 27001 Certification: What It Means for Data Security
ISO 27001 is the international information security management standard. Certification demonstrates systematic controls across physical security, access management, incident response, and supplier security.
