Visual anonymization for images and graphics

Not all sensitive information is in text: signatures, photos, stamps and handwriting also identify people. Visual anonymization detects and hides these elements in PDFs.

Elements to protect

• Handwritten and digital signatures.
• Photos of people in reports.
• Stamps with identifying data.
• Handwritten margin notes.

Techniques

Combination of visual AI detection and irreversible redaction over identified areas.

When text anonymization is not enough

Scans, signed minutes and reports with patient or citizen photos need visual detection. Without covering signatures, faces and stamps, the document still identifies people even if the text is redacted.
