Viscount Colville of Culross (CB)

My Lords, I am pleased to support the noble Baroness, Lady Owen, in the latest stage of her campaign to stop online image abuse. I too applaud her success against deepfakes in the Data (Use and Access) Act. The Government have done much good work to progress that campaign in this Bill, but the distribution of these images, which causes so much harm, must be stopped. As many other noble Lords have said, we need to ensure that the Bill creates the powers to stop the sharing of these images across the internet. Noble Lords who were involved in the debates on the Online Safety Bill understand that ensuring that the tech companies stop the prioritisation and dissemination of harms is central to stopping harm being spread on the internet. Amendment 299 and the others in this group will do that. I shall focus on Amendments 295BC on hashing and 295BD on the NCII register, which will be crucial to ensuring that any sharing of intimate images will be radically reduced and, I hope, stopped. There has been good work by the Internet Watch Foundation in hash matching and setting up a register of illegal intimate images of children. It is funded by the industry and has been effective in massively reducing the traffic in CSAM. If these amendments are adopted, it will be a great thing to bring these protections to the adult online world. Verification of NCII is already expanding. It happens at platform moderation level, where there are measures to increase the number of images verified by training NGOs on submissions to the StopNCII.org portal. This will ensure that they will submit hashes globally via a global clearing centre. There is work under way with the national centre for violence against women and girls to improve police response to NCII abuse, so they can proactively report content for removal and hashing. However, it needs to be mandated to ensure that this system becomes more extensive. I urge that, if these amendments are accepted, hash-matching technology remains nimble. I understand that MD5 video hash-matching technology might not respond to slight tweaks of a video. As a result, the video cannot be checked against the register, rendering hash matching ineffective. Other technologies, such as PDQ for stills, looks at the perceptual nature of the image and can still create a match, even if the image is cropped or edited. I urge the creators of hash-matching technology to continue the arms race against AI and ensure that subtle AI tweaks to a hash-matched image can be matched on the NCII register. StopNCIA software is already doing an amazing job in generating 1.8 million hashes and preventing thousands of intimate images being shared across the internet. Imagine how effective it will be if this technology is mandated for adult NCII for all platforms and enforced by Ofcom. I urge the Minister to accept these amendments and save thousands of users from harm and misery.
