Face recognition has been one of the technologies used in various walks of the modern life. Facial recognition is used in the applications like security and defense, retail and marketing, healthcare and hospitality. Security and defense holds really a great altitude of usage of facial recognition in comparison with the other applications.



The origin of facial recognition dates back to 1800s. As immediate as the camera was invented, law enforcement started utilizing the potential of facial recognition by recording the images of the criminals to identify repeated offenders.


Despite such critical application, San Francisco decided to ban the usage of facial recognition from May 2019. San Francisco is the first country in the world to impose ban on facial recognition. Recently, the Government of Boston joined the list by imposing ban on facial recognition.


There was a situation where five watches were stolen from Shinola retail store, which were of $3800 worth. As a part of investigation, the police collected the CCTV footage and ran a facial recognition software with the person identified from the footage. The software recognized the person as Robert Julian-Borchak Williams (42 YO) hailing from Farmington Hills, Michigan. Finally, charges against Williams were dropped off for the reason that the facial recognition software had a false hit in identification.


In this context, the city council of Boston voted to ban the use of such software. This measure will reach the Mayor of Boston Marty Walsh. One of the sponsors of the bill Councilor Ricardo Arroyo noted that the facial recognition software used by the police is inaccurate for the people of color.

Apart from this practical example of facial recognition software error, MIT has conducted an analysis on understanding the accuracy of such software. This study revealed that the error rate of light-skinned men is 0.8% and 34.7% that of dark-skinned women.

It has an obvious racial bias and that's dangerous. But it also has sort of a chilling effect on civil liberties. And so, in a time where we're seeing so much direct action in the form of marches and protests for rights, any kind of surveillance technology that could be used to essentially chill free speech or ... more or less monitor activism or activists is dangerous.


The Boston Police Commissioner William Gross said that the modern technology is not reliable. In his words, “Until this technology is 100%, I'm not interested in it. I didn’t forget that I'm African American and I can be misidentified as well.”


Based on the recent revolution against racism, William’s case is really alarming. Just because of a software bug, he was accused and appeared in the court. In the era of breaking all the inequalities, the software we learn, the algorithms implemented in Machine Learning software and the application of such algorithms should be designed enhanced care.


Facial recognition tech is used in our day to day life to unlock smartphone or to tag friends on social media. Some airports use this to scan passengers before they board flight. Departments of motor vehicles use this tech to detect license fraud, identify theft.

Most common use of face recognition technology is law enforcement departments. After Williams case, many cities already banned using facial recognition technology.


Detroit police were trying to find out the guy whole stole watches from a Shinola retail store. The worth of the watches stolen are expected to be $3,800. The officers got access to the store security footage, zoomed into the grainy footage and squared out the picture of the suspect. Later, the picture of the suspect was run through the facial recognition software. The software came up with the person as Robert Julian-Borchak Williams, a 42-year-old from Farmington Hills, Mich., which is about 25 miles northwest of Detroit.


In January, Williams’ was arrested and taken into interrogation room. Police put three photos in front of him, out of which two photos were from the surveillance camera in the store and a photo from state-issued driver’s license. Williams denied saying that he is not the one from the surveillance footage but agreed that the person in the license is himself.


Williams was in remand for 30 hours and then release on a court bail until a court hearing on the case. At the hearing, court announced that the charges against Williams were dropped because of insufficient evidence. You can check the entire report here.

Williams is the first person in the U.S. who got wrongfully arrested based on the false hit produced by facial recognition technology. 


The American Civil Liberties Union (ACLU) of Michigan filed a complaint against the Detroit Police Department asking the police stop using the software in investigations. After Williams case, the department passed a bill of new rules. Now, only still photos should be used for facial recognition not the surveillance footages. Only in the case of violent crimes, facial recognition should be used.


Many Academic and government studies have demonstrated that facial recognition systems misidentify color people more often than others. Most of the nation’s law enforcement agencies have access to face recognition tools and most of the time, people who are arrested using facial recognition are not told face recognition was used to arrest them.


Companies like Amazon, Microsoft and IBM have announced that they are not selling face recognition technologies to law enforcement agencies, however many other smaller, more specialized companies, like South Carolina based DataWorks Plus, the company which supplied the Detroit Police Department with its face-scanning software are still ready to make deals.


DataWorks Plus has supplied the technology to government agencies in Santa Barbara, California, Chicago and Philadelphia.


Williams case is a wake-up call to lawmakers to enact new rules into the law to avoid such cases in future.
