In brief: Amazon Nova 2 Lite orchestrates a pipeline for automatic anonymisation of personal data in images by coordinating segmentation and OCR tools, and captures complex cases such as mirrored or partially visible PII.
Amazon has unveiled a multi-stage pipeline that leverages the Amazon Nova 2 Lite language model to automatically detect and anonymise personal data in images. The solution coordinates specialised tools such as the Segment Anything Model (SAM 3) and Amazon Textract to reliably remove difficult-to-detect PII cases such as mirrored faces, ID numbers, or location information.
When sharing data between teams, with partners, or for training machine learning models, organisations must ensure that personal information (PII) is no longer identifiable. Regulatory requirements such as the GDPR and PCI-DSS mandate this; faulty anonymisation leads to fines, reputational damage, and loss of customer trust.
The challenge is that PII in images occurs in unexpectedly complex forms: a cropped face at the image edge, a face reflection on a car’s paint surface, partially visible street signs combined with other visual clues, or documents with names and addresses on a desk in the background. Such cases regularly overwhelm simple masking tools. Amazon Nova interprets image content holistically and can assess contextually whether something constitutes PII – even in subtle cases.
The solution uses Amazon Nova 2 Lite as the central coordination instance, which controls the detection of PII elements and delegates to specialised services: the Segment Anything Model (SAM 3) performs pixel-accurate segmentation once Nova has identified visual PII. Amazon Textract extracts text, handwriting, and layout from images via optical character recognition (OCR); Nova then assesses contextually which text fragments are sensitive. Redaction thus reaches difficult-to-detect cases such as fingerprints, ID documents, or licence plates at any angle.
All services are available through Amazon Bedrock. The procedure preserves the visual value of the image while removing personal data with pixel-level precision.
