The Homeland Security Department is looking to upgrade the software it uses to analyze biometric data on hundreds of millions of people around the globe, and it plans to store that information in Amazon’s cloud.

The agency’s Office of Biometric Identity Management will replace its legacy biometric analysis platform, called the Automated Biometric Identification System, or IDENT, with a new, more robust system hosted by Amazon Web Services, according to a request for information released Monday.

IDENT essentially serves as an enterprisewide clearinghouse for troves of biometric and biographic data collected by the Transportation Security Administration, Customs and Border Protection, Secret Service and other Homeland Security components. The system links fingerprint, iris and face data to biographic information, allowing officials to quickly identify suspected terrorists, immigration violators, criminals and anyone else included in their databases.

In total, IDENT contains information on more than 250 million people, a Homeland Security spokesperson told Nextgov.

According to the solicitation, Homeland Security is in the process of replacing IDENT with the Homeland Advanced Recognition Technology System, or HART. The new system will include the same biometric recognition features as its predecessor, and potentially additional tools that could identify individuals based on DNA, palm prints, scars, physical markings and tattoos.

Whereas IDENT stores records in government-run data centers, the Homeland Security solicitation states “HART will reside in the Amazon Web Services (AWS) FedRAMP certified GovCloud.” Further, “biometric matching capabilities for fingerprint, iris, and facial matching will be integrated with HART in the Amazon Web Services GovCloud.” Amazon Web Services will also store HART’s biometric image data.

Amazon Web Services’ GovCloud US-East and US-West regions are data centers specifically built by the company to house some of the government’s most restricted information. AWS is no stranger to hosting sensitive government data, having already claimed the CIA, Defense Department, NASA and other federal agencies as customers in part because of perceived security improvements over government legacy systems.

When reached for comment, an AWS spokesperson referred inquiries to DHS.

In 2018, Northrop Grumman won a $95 million contract to develop the first two stages of the HART system, and its contract is set to expire in 2021. The department plans to use responses to the latest solicitation to inform its strategy for further developing the platform, the DHS spokesperson said.

Specifically, officials are asking vendors for ideas on how to build those multiple identification functions into the new system, while leaving room to add any new recognition “modalities” as they arise. Officials also want input on developing a handful of general reporting, analytics and search tools, as well as desktop and mobile web portals where Homeland Security employees can access the system.

Interested vendors must respond to the request by July 17.

In addition to the hundreds of millions of records stored locally in its IDENT system, Homeland Security can also access swaths of biometric information housed at other agencies.

According to the solicitation, the agency shares biometric data and technology with the Defense Department and the FBI, which can access some 640 million photos for its own facial recognition operations. Officials also said they can tap into the State Department’s Consular Consolidated Database—which contained nearly 500 million passport, visa and expat records as of 2016—as well as the databases of “several foreign governments as well as state, local, tribal and territorial law enforcement agencies.”

The government’s use of biometric technology, particularly facial recognition, has come under sharp scrutiny in recent months. Members of the House Oversight Committee have expressed broad bipartisan support for reining in the use of biometrics at agencies like the FBI, and on Monday, a group of lawmakers raised concerns about CBP’s expanding facial recognition program.
