Federal agencies are worried face masks may be used to evade facial recognition technology


Federal agencies in the US are worried face masks may be used to evade facial recognition technology

  • Documents show the DHS is worried that face masks may hinder the use of facial recognition technology
  • Officials worry that they could be used by ‘violent extremists’
  • There is no current evidence that masks are being used by threat groups 

The The US Department of Homeland Security is reportedly worried that face coverings will stymie the police’s use of facial recognition technology.

According to a report from The Intercept, a bulletin drafted by the DHS discusses the effects of widespread use of face coverings in a correspondence with other federal agencies, including Immigration and Customs Enforcement (ICE).

‘The potential impacts that widespread use of protective masks could have on security operations that incorporate face recognition systems — such as video cameras, image processing hardware and software, and image recognition algorithms — to monitor public spaces during the ongoing Covid-19 public health emergency and in the months after the pandemic subsides,’ reads the bulletin according to The Intercept.

The bulletin, which was obtained via a trove of police documents leaked in the ‘BlueLeaks’ hack on law enforcement agencies, mentions that the masks could be used by extremists to avoid facial recognition technology but says there is no current evidence that any such group is currently doing so.

‘[There is] no specific information that violent extremists or other criminals in the United States are using protective face coverings to conduct attacks,’ reads the document.

Facial recognition technology has risen to prominence among law enforcement in the US and around the world as a tool to identify and track suspects with the help of companies like Amazon and IBM who design the sophisticated AI software.

In recent months, the technology has also been used to track protesters of police brutality and supporters of Black Lives Matter in cities like San Diego.

Companies have reportedly tried to adapt their algorithms to recognize masked faces according to The Intercept, but there’s no evidence that those systems can identify faces accurately. 

Some of those efforts have involved photoshopping masks onto people’s faces in an effort to familiarize AI with the process.

As noted by The Intercept, Homeland Security’s Customs and Border Protection has claimed that the software the agency uses to scan international travelers has had some success with masks.

Subjects scanned by CBP are directly facing the camera, however, making it much easier to discern specific facial characteristics.  

HOW DOES FACIAL RECOGNITION TECHNOLOGY WORK?

Facial recognition software works by matching real time images to a previous photograph of a person. 

Each face has approximately 80 unique nodal points across the eyes, nose, cheeks and mouth which distinguish one person from another. 

A digital video camera measures the distance between various points on the human face, such as the width of the nose, depth of the eye sockets, distance between the eyes and shape of the jawline.

The military is working on applying a similar version of this with AI to track people across the country

This produces a unique numerical code that can then be linked with a matching code gleaned from a previous photograph.

Experts believe that facial recognition technology will soon overtake fingerprint technology as the most effective way to identify people.
