Limina supports scanning images for PII and creating de-identified or redacted copies. Limina’s supported entity types function across each file type, with localized variants of different PII (Personally Identifiable Information) entities, PHI (Protected Health Information) entities, and PCI (Payment Card Industry) entities being detected. Our Supported Languages and Supported Entity Types page provides a more detailed look.

How Images Are Processed

Image files are processed as follows:
  1. Non-text PII such as faces and license plates are detected.
  2. Additionally the image is run through an OCR system to detect any text present.
  3. The output of the OCR system is then passed to a PII detection module.
  4. Any PII found in the previous steps is de-identified via blurring or black box redaction.
You can configure the OCR System by setting it as an Environment Variable or sending it in the request object. Check out our OCR Guide to further understand the OCR modes and their usage.

​
Constraints

  • There is limited support for 8-bit PNG images.
  • Multi-page TIFF images are only supported on versions >=4.2.1. Earlier versions will process and return the first page of a multi-page TIFF.
