# Introduction

The IDOL PHI Package contains tools that allow you to locate Protected Healthcare Information (PHI) in your data, to ensure compliance with regulations such as the Standards of Privacy of Individually Identifiable Health Information implemented as part of the Health Insurance Portability and Accountability Act (HIPAA).

The IDOL PHI Package has two types of tools:

- IDOL Eduction Grammars (.ecr and files). IDOL Eduction is a tool for finding entities (small pieces of information such as names and phone numbers) in text. Eduction grammars contain descriptions of the entities. In some cases, this might be a list of fixed values (such as names), and in others it might be pattern matching tools that find data of a particular type (such as a set of digits that make up a phone number). The Eduction grammars included in the IDOL PHI Package describe different kinds of personally identifiable information, so that you can find these in your data.

- IDOL AgentBoolean IDX. IDOL AgentBoolean is a method of storing entities and querying for them that uses the IDOL Agentstore component (a specially configured IDOL Content component), rather than Eduction. The IDX files are index files that contain the details of the entities, which you can index into the IDOL Agentstore component.
