Identifying when someone is wearing Meta’s new ‘pervert glasses’ will become easier under a new proposal that will require users to be dressed in a full Rolf Harris costume and carry a wobble board. Privacy advocates say the new approach strikes the right balance between self expression and consent. “We considered other methods, such as requiring users to carry a sign that read ‘I am secretly filming you’. But in the end we felt that a weird moustache, an oversized trench coat and an extra leg is probably a more effective indicator. Early trials in Bondi were a success, with residents being able to spot 100% of the time when they were being filmed without permission.
