China’s Surveillance cameras with ‘Skin Color Analytics’ raise concerns

WASHINGTON: Chinese surveillance equipment maker Dahua is selling cameras with what it calls a “skin colour analytics” feature in Europe according to a report by the IPVM (Internet Protocol Video Market), a US-based security and surveillance industry research group, as cited by Voice of America.

In the July 31 IPVM report accessed by VOA Mandarin, “The company defended the analytics as being a ‘basic feature of a smart security solution.’”

VoA is the state-owned news network and international radio broadcaster of the United States of America, which produces digital, TV, and radio content that is shared worldwide.

In February 2021, IPVM and the Los Angeles Times reported that Dahua provided a video surveillance system with “real-time Uyghur warnings” to the Chinese police that included eyebrow size, skin colour and ethnicity.

IPVM’s 2018 statistical report shows that since 2016, Dahua and another Chinese video surveillance company, Hikvision, have won contracts worth USD 1 billion from the government of China’s Xinjiang province, a centre of Uyghur life.

Dahua’s ICC Open Platform guide for “human body characteristics” includes “skin colour/complexion,” ac-cording to the report. In what Dahua calls a “data dictionary,” the company says that the “skin colour types” that Dahua analytic tools would target are “yellow,” “black,” and “white.” VOA Mandarin verified this on Dahua’s Chi-nese website, VOA reported.

The IPVM report also says that skin colour detection is mentioned in the “Personnel Control” category, a feature Dahua touts as part of its Smart Office Park solution intended to provide security for large corporate campuses in China.

“Basically what these video analytics do is that, if you turn them on, then the camera will automatically try and determine the skin colour of whoever passes, whoever it captures in the video footage,” VOA quoted Charles Rollet, the co-author of the IPVM report.

“So that means the camera is going to be guessing or attempting to determine whether the person in front of it … has black, white or yellow, in their words, skin colour,” he added.

The IPVM report said that Dahua is selling cameras with the skin colour analytics feature in three European na-tions. Each has a recent history of racial tension, Germany, France and the Netherlands.

Dahua said its skin tone analysis capability was an essential function in surveillance technology.

In a statement to IPVM, Dahua said, “The platform in question is entirely consistent with our commitments to not build solutions that target any single racial, ethnic, or national group. The ability to generally identify observable characteristics such as height, weight, hair and eye colour, and general categories of skin colour is a basic feature of a smart security solution.”

IPMV said the company has previously denied offering the mentioned feature, and colour detection is uncom-mon in mainstream surveillance tech products.

In many Western nations, there has long been a controversy over errors due to skin colour in surveillance tech-nologies for facial recognition. Identifying skin colour in surveillance applications raises human rights and civil rights concerns.

“So it’s unusual to see it for skin colour because it’s such a controversial and ethically fraught field,” Rollet said.

Anna Bacciarelli, technology manager at Human Rights Watch (HRW), told VOA that Dahua technology should not contain skin tone analytics.

“All companies have a responsibility to respect human rights, and take steps to prevent or mitigate any human rights risks that may arise as a result of their actions,” she said in an email.

“Surveillance software with skin tone analytics poses a significant risk to the right to equality and non-discrimination, by allowing camera owners and operators to racially profile people at scale — likely without their knowledge, infringing privacy rights — and should simply not be created or sold in the first place” she added.

Dahua denied that its surveillance products are designed to enable racial identification. On the website of its US company, Dahua says, “Contrary to allegations that have been made by certain media outlets, Dahua Technology has not and never will develop solutions targeting any specific ethnic group.”

The US Federal Communications Commission determined in 2022 that the products of Chinese technology companies such as Dahua and Hikvision, which has close ties to Beijing, posed a threat to US national security. (ANI)
