Amazon shareholders are calling on the company to stop selling its cloud-based facial recognition software to government agencies on the grounds it could put people’s civil liberties at risk.

In a two-page missive, its shareholders claim the company has provided “little evidence” sales of its Rekognition service are being regulated to protect against it being used by organisations to facilitate racial profiling and nefarious surveillance, for example.

The image analysis technology made its debut in December 2016 at the cloud giant’s annual Re: Invent customer and partner conference, and – along with other similar tools – has found itself subject to misuse concerns from civil liberties and human rights activities. Particularly when deployed by government agencies and law enforcement bodies.

In light of these concerns, shareholders are urging Amazon’s board of directors to stop selling the software to government agencies unless it can provide independent evidence that it does not “cause or contribute to actual or potential violations of civil and human rights”, the letter states.

It also claims the technology is being “marketed” at the US Immigration and Customs Enforcement (ICE), who are already known to be using other parts of AWS’s wider cloud portfolio, and has been piloted by police forces in Florida and Oregon.

The letter’s creation has been organised by non-profit open internet campaigners Open Mic, who claim Rekognition’s ability to identify individuals from images and videos has proven to be biased, inaccurate and dangerous in some tests.

It also claims the content of the letter is supported by “hundreds” of Amazon employees, and 150,000 people who have signed a petition calling for sales of Rekognition to government agencies to be stopped.

Amazon Web Services used Re:Invent 2016 to stake its claim as an early adopter of machine learning, while revealing details of its plans to boost the technology’s take-up among everyday developers.

Michael Connor, executive director of Open Mic, said the action is necessary to protect the company and its investors.

“It’s a familiar pattern: a leading tech company marketing what is hailed as breakthrough technology without understanding or assessing the many real and potential harms of that product,” said Connor.

“Sales of Rekognition to government represent considering risk for the company and investors. That’s why it’s imperative those sales be halted immediately.”

It is understood the contents of the letter will be voted on during Amazon’s annual meeting, which is taking place in Spring 2019.

Computer Weekly contacted AWS for comment on this story, and was directed to a blog post authored by Matt Wood, general manager of deep learning and artificial intelligence (AI), in 2018, where he directly addresses concerns about the potential for Rekognition to be misused.

It outlines the firm’s commitment to addressing concerns about how its technologies are used through its acceptable use policy. This states that any organisation that falls foul of this policy will lose access to its services.

The firm previously severed ties with whistle-blowing website Wikileaks on similar grounds in 2010, citing the fact the firm was using its services to host content that does not belong to it.
