  • Home Office to spend £1.3M on age-determining algorithm | The Register | I wonder what their acceptable false positive rate will be?

    …the next step for the UK government will be to obligate phones to be installed with state spyware, following the examples of Russia & China: The government’s expanding surveillance efforts are pushing users toward a new state-backed app called Max, which security experts warn would share private data with authorities, leaving Russians cut off from
