The platform will use AI-powered systems to detect nude images and identify sextortion accounts
Instagram will start testing new tools within weeks to fight "Sextortion", a form of blackmail involving intimate pictures sent online.
The tools include "Nudity protection", which blurs naked images in direct messages.
Much of the sextortion Instagram sees on its platform is the work sophisticated criminal gangs seeking money.
Its nudity protection system, first revealed in January, uses artificial intelligence running entirely on the user's device to detect nude images in direct messages and give users a choice whether to view them.
It is designed "Not only to protect people from seeing unwanted nudity in their DMs, but also to protect them from scammers who may send nude images to trick people into sending their own images in return," Instagram said.
Instagram stresses the system, which is opt-in for adults, does not report nude images to the company automatically, though users will be reminded they can block and report accounts if they wish.
For people who may have interacted with an account removed for sextortion, Instagram is testing pop-up messages that will direct them to expert advice and support.
Instagram also says it will share more data to fight sextortion and child abuse with other tech firms through an initiative called Lantern.
