ACRP LRD 42 73 APPENDIX: AIRPORT TECHNOLOGY AND PRIVACY A. Technology Use Case Review 1. Objective & Scope This document aims to identify and categorize airport tech- nology that captures or processes PII. It focuses on PII related to passengers and public users of the airport environment. While the airport is at the center of this research the analysis is adapt- able to other airport stakeholders collecting, retaining, and using data. It does not address the regular capture of data of employees in the ordinary course of business of the airport, airlines, FAA, TSA, CBP, or any other third party contracted to support the airport except that data used in conjunction with airport access control measures. It focuses on technology typically operated by or for an airport (not by the airlines, FAA, CBP, TSA etc.). 2. Defining PII For this review, we use the definition of PII as provided by the NIST in its âGuide to Protecting the Confidentiality of Per- sonally Identifiable Information (PII).â PII is âany information about an individual maintained by an agency, including (1) any information that can be used to distinguish or trace an individ- ualâs identity, such as name, social security number, date and place of birth, motherâs maiden name, or biometric records; and (2) any other information that is linked or linkable to an indi- vidual, such as medical, educational, financial, and employment information.â B. Use Case Analysis The analysis below offers a summary of use cases im ple- mented or under consideration for implementation at U.S. air- ports. A brief description is provided for each use case. Also provided is a brief summary of the types of data involved in supporting the use case. This involves use case application for the following areas of airports: â¢ Technology Services; â¢ Terminal Operations; â¢ Landside Operations; â¢ Concessions; and â¢ Security. The outlines for theses use cases demonstrate common data types that will need to be understood and addressed by airports and airport stakeholders. These use cases will be expanded, and additional use cases may be added as this project continues.
