’Show Me Your Papers’ Becomes ’Open Your Eyes’ as Borderland Sheriffs Expand Iris Surveillance George Joseph - The Intercept
go to original July 8, 2017

Since his inauguration, President Donald Trump has found little funding for his “big, beautiful wall.” In the meantime, however, another acquisition promised to deter unauthorized immigrants is coming to the border: iris recognition devices. Thirty-one sheriffs, representing every county along the U.S.-Mexico border, voted unanimously on April 3 to adopt tools that will capture, catalogue, and compare individuals’ iris data, for use both in jails and out on patrol. Biometric Intelligence and Identification Technologies, the company behind the push, has offered the sheriffs a free three-year trial, citing law enforcement’s difficulties in identifying unauthorized immigrants whose fingerprints can be disfigured through manual labor or self-inflicted wounds.

Iris recognition is just the latest surveillance technology helping fortify what the White House hopes will make up a “digital wall,” a concept that many border sheriffs view as less intrusive than Trump’s envisioned 30-foot barricade stretching from Brownsville, Texas, to San Diego, California. For law enforcement, the tool promises to help identify people without reliable fingerprints and to deter repeat border crossers. And for Biometric Intelligence and Identification Technologies, which frequently goes by BI2, rapid border expansion means its existing national iris database will receive a huge influx of biometric information on unauthorized immigrants, boosting its product’s capabilities to potential law enforcement clients across the country.

While this high-tech approach to immigration enforcement has not generated anything close to the controversy of Trump’s proposed wall, the campaign to expand iris scan collection on the border is of a piece with the president’s denunciations of Mexican immigrants as rapists and criminals.

... In the coming months, BI2’s iris recognition devices will be installed in every sheriff’s department along the U.S.-Mexico border. Each department will receive both a stationary iris capture device for inmate intake facilities and, eventually, a mobile version, according to Sheriff Joe Frank Martinez of Val Verde County, Texas, who currently serves as the president of the Southwestern Border Sheriff’s Coalition.

The technology works by taking a high-resolution image of a person’s iris with a special infrared illumination camera, and then creating an individualized iris template based on that image. The templates exploit nearly 240 unique characteristic elements in the iris, compared to the 40 to 60 used for fingerprints, resulting in far fewer false matches. To make an identification, BI2’s iris recognition program compares an individual’s iris against the over 987,000 iris scans held in its private database, which collects images from over 180 law enforcement jurisdictions nationwide.
