My nude images were shared online at 14- here's why I blame Big Tech

Leah Juliett , 27 , sent nude images to a boy on Facebook when she was 14 .

They were shared online, at first with other children at school and then on anonymous internet messaging boards.

Now 27 , the advocate says the experience was devastating - and inspired her journey to become an activist fighting against what they see as Big Tech’s inaction to prevent image-based child sex abuse.

Now campaigns for the Heat Initiative , which aims to make Apple accountable for the spread of abuse images on the company's iCloud .

Juliett said: 'The most basic thing that they could do today is they can initiate basic hash, hash matching detection and iCloud , which basically converts a piece of known CSAM into a unique string of numbers through an algorithm.

It makes the image into a digital fingerprint of sorts and then is compared against a list of other digital fingerprints.

Apple 's director of user privacy and child safety Erik Neuenschwander wrote: 'Scanning every user’s privately stored iCloud data would create new threat vectors for data thieves to find and exploit. It would also inject the potential for a slippery slope of unintended consequences'.
