This is a pilot project in Australia:

Individuals who have shared intimate, nude or sexual images with partners and are worried that the partner (or ex-partner) might distribute them without their consent can use Messenger to send the images to be "hashed."

Facebook will store these images for a short period of time before deleting them to ensure it is enforcing the policy correctly, the company said.
