Consistent with the DHS Fair Information Practice Principles (FIPPs), TSA retains personally identifiable information (PII) only for as long as is necessary to fulfill the specified purpose(s) of testing the accuracy of facial comparison technology. DHS FIPPs and TSA’s PIAs provide guidance on matters such as transparency, specific use limitations, data minimization, and purpose specification for our facial comparison technology. Additional information on data protection procedures for each test is available in TSA’s PIAs. In short, TSA informs the traveler in advance of data collection, securely transits the data and images for testing, then deletes the data.
