It noted that trauma can “age” a child’s appearance.\nThe Home Office plans to use the technology alongside checks by immigration officers. A spokesperson said: “Age assessments are a vital tool in maintaining border security. As part of our work to make this process more robust and consistent, we are exploring cutting-edge AI technology to verify migrants’ ages.”\nPetra Molnar, who co-founded the advocacy group Migration and Tech Monitor, said this was the latest in a series of failed attempts across Europe to implement tech and AI into border policy.\nShe said previous attempts in Europe to implement AI-powered lie-detection systems for screening refugees had proven to be “snake oil” and did not progress beyond pilot schemes.\nShe likened the use of facial age-estimation technology to “the study of skulls and skull shapes” by colonial-era scientists to categorise different ethnic groups, saying that like the discredited 19th-century pseudoscience of phrenology, these systems similarly relied on categorising physical features to determine age.\n“The context really matters here,” said Molnar. “We know that trauma ages you.
