Textract and Comprehend

Amazon Textract pulls the text and structural information from files and Amazon Comprehend performs a deeper analysis to detect Personal Identifiable Information (PII) Any representation of information that permits the identity of an individual to whom the information applies to be reasonably inferred by either direct or indirect means. Further, PII is defined as information: (i) that directly identifies an individual (e.g., name, address, social security number or other identifying number or code, telephone number, email address, etc.) or (ii) by which an agency intends to identify specific individuals in conjunction with other data elements, i.e., indirect identification. Additionally, information permitting the physical or online contacting of a specific individual is the same as personally identifiable information. in English or Spanish text documents. Depending on your needs, you can specify one or more types of PII you want to identify.

Amazon Comprehend refers to the different types of PII as entities. A list of PII entities is included in this topic. There is an ALL option available in the Comprehend Type configuration that includes all the options listed. Keep in mind the maximum number character for a text field is 100.

Here we provide the steps to set up a basic configuration using Comprehend PII detection.

Requirements

Before you start a new Textract configuration you need the following:
