Redacting or identifying personally identifiable information - Amazon Transcribe

Redacting or identifying personally identifiable information

Use content redaction to omit sensitive personally identifiable information (PII) from your transcription results. Use content identification to flag PII in your transcript without redacting it.


The redaction feature is designed to identify and remove sensitive data. However, due to the predictive nature of machine learning, Amazon Transcribe may not identify and remove all instances of sensitive data in your transcript. We strongly recommend that you review any redacted output to ensure it meets your needs.

The redaction feature does not meet the requirements for de-identification under medical privacy laws, such as the U.S. Health Insurance Portability and Accountability Act of 1996 (HIPAA).

PII redaction can be performed on batch transcription jobs and streaming transcriptions, whereas PII identification can only be performed on streaming transcriptions. With batch transcription jobs, you can choose to have both a redacted and an unredacted transcript.

Amazon Transcribe can identify the following types of PII:
