Philter

Take Control of PHI and PII

Philter can remove and anonymize Personally Identifiable Information (PII) and Protected Health Information (PHI) from text.

Capabilities of Philter

  • Removal of PHI from text. Philter uses natural language processing to identify protected health information from text.
  • Anonymization (de-identification) of PHI from text. Philter can replace PII and PHI with similar but random values. For example, names are replaced with random names and phone numbers with random phone numbers. With consistent anonymization your documents can remain useful for other applications and uses by not losing meaning.
  • Detection of PHI in text. (Answers the question, “Is there PHI in my text?”) This capability involves analyzing your text to assign it a numeric score that indicates the likelihood of protected health information in the text.
  • Configurable sensitivity level to control Philter’s detection and removal.

How Philter Works

Philter uses a multi-phased approach to identify and remove PII and PHI. Philter analyzes the text it receives for PII and PHI. Some information is recognizable through patterns, such as social security numbers and phone numbers. Detecting other types of PHI is more complex because it does not follow patterns. Information such as patient names are identified through trained neural network models created specifically to detect these types of information.

Please note that model-based detection is not an exact science and Philter’s accuracy and performance should be evaluated against your data prior to a production deployment. Adjusting Philter’s configured sensitivity can have a significant impact on the accuracy.

Community and Enterprise Editions

Philter will be available in community and enterprise editions.

Getting Started

Philter Enterprise Edition can be launched on Amazon Web Services and Microsoft Azure via their respective marketplaces.
