I agree with the noble Baroness, which is precisely why I am suggesting that we need to consider whether privacy should be sacrificed totally in relation to the argument around encryption. It is difficult, and I feel awkward saying it. When I mentioned a silver bullet I was not talking about the noble Baroness or any other noble Lords present, but I have heard people say that we need this Bill because it will deal with child abuse. In this group of amendments, I am raising the fact that when I have talked about encryption with people outside of the House they have said that we need to do something to tackle the fact that these messages are being sent around. It is not just child abuse; it is also terrorism. There is a range of difficult situations.
Things can go wrong with this, and that is what I was trying to raise. For example, we have a situation where some companies are considering using, or are being asked to use, machine learning to detect nudity. Just last year, a father lost his Google account and was reported to the police for sending a naked photo of their child to the doctor for medical reasons. I am raising these as examples of the problems that we have to consider.
Child abuse is so abhorrent that we will do anything to protect children, but let me say this to the Committee, as it is where the point on privacy lies: children are largely abused in their homes, but as far as I understand it we are not as yet arguing that the state should put CCTV cameras in every home for 24/7 surveillance to stop child abuse. That does not mean that we are glib or that we do not understand the importance of child abuse; it means that we understand the privacy of your home. There are specialist services that can intervene when they think there is a problem. I am worried about the possibility of putting a CCTV camera in everyone’s phone, which is the danger of going down this route.
My final point is that these services, such as WhatsApp, will potentially leave the UK. It is important to note that. I agree with the noble Lord, Lord Allan: this is not like threatening to storm off. It is not done in any kind of pique in that way. In putting enormous pressure on these platforms to scan communications, we must remember that they are global platforms. They have a
system that works for billions of people all around the world. A relatively small market such as the UK is not something for which they would compromise their billions of users around the world. As I have explained, they would not put up with it if the Chinese state said, “We have to see people’s messages”. They would just say, “We are encrypted services”. They would walk out of China and we would all say, “Well done”. There is a real, strong possibility of these services leaving the UK so we must be very careful.
