WASHINGTON, (Reuters) – The U.S. House of Representatives has opened an investigation into ID.me’s identity verification contractor ID.me. They have expressed serious concerns about ID.me’s efficacy and privacy, as well as the security of the technology that it offers to 10 federal agencies.

First reported by The Washington Post was a letter sent to ID.me chief executive Blake Hall by Carolyn Maloney (chair of the House Oversight Committee) and Jim Clyburn (Democratic whip). The letter was dated Thursday.

This letter expresses concern over facial recognition software being used to protect important transactions with the Internal Revenue Service. There are also concerns about accuracy and privacy.

ID.me, on the other hand, highlighted its involvement in fighting foreign criminal gangs with government benefits fraud.

“We look forward to providing important information to the Committee on how ID.me has expanded access to government for disadvantaged Americans, including individuals who do not have credit history, are underbanked or are without a home,” the company said in a statement.

ID.me was contacted by the lawmakers to provide information on its services to federal agencies, 30 state governments and to show how frequently it fails to identify users, what biometric data has been collected, and how long they waited to get help.

Also, they wanted to know how many times ID.me found the ID.me suspected fraud. And if this determination was made by a human review or artificial intelligence.
