My Lords, there have been some excellent speeches so far. The noble Lord, Lord Allan of Hallam, brilliantly laid out why these amendments matter, and the noble Lord, Lord Moylan, explained why this has gained popular interest outside of the House. Not everything that goes on in this House is of interest and people do not study all of the speeches made by the noble Lord, Lord Moylan, even though they are always in the public sphere, but this particular group of amendments has elicited a huge amount of discussion.
We should remember that encrypted chat has become an indispensable part of the way that we live in this country and around the world. According to the Open Rights Group it has replaced the old-fashioned wired telephone—a rather quaint phrase. The fact that the citizens of the United Kingdom think that chat services matter so much that they are used by 60% of the total population should make us think about what we are doing regarding these services.
End-to-end encryption—the most secure form of encryption available—means that your messages are stored on your phone; people feel that they are in control because they are not on some server somewhere. Even WhatsApp cannot read your WhatsApp messages; that is the point of encryption. That is why people use it: the messages are secured with a lock which only you and the recipient have the special key to unlock to read them.
Obviously, there are certain problems. Certain Government Ministers wanted to voluntarily share all of their WhatsApp messages with a journalist who would then share them with the rest of us. If your Lordships were in that group you might have thought that was a rude thing to do. People have their WhatsApp messages leaked all the time, and when it happens we all think, “Oh my God, I’m glad I wasn’t in that WhatsApp group”, because you assume a level of privacy, even though as a grown-up you need to remember that somebody might leak them. But the main point is that they are a secure form of conversation that is widely used.
Everyone has a right to private conversations. I was thinking about how, when society closed down during the lockdown period, we needed technology in order to communicate with each other. We understood that we needed to WhatsApp message or Zoom call our friends and family, and the idea that this would involve the state listening in would have appalled us—we considered that our private life.
We want to be able to chat in confidence and be confident that only ourselves and the recipients can see what we are sharing and hear what we are saying. That is true of everyday life, but there are very good specific cases to be made for its importance, ranging through everything from Iranian women resisting the regime and communicating with each other, to all the civil liberties organisations around the world that use WhatsApp. The security of knowing that you can speak without Putin listening in or that President Xi will not be sent your WhatsApp messages is important.
The Government keep assuring us that we do not need to worry, but the Bill gives Ofcom the power to require services to install tools that would require the surveillance of encrypted communications regarding child exploitation and terrorism content, for example. Advocates and people on my side argue that this is not possible without undermining encryption because, just as you cannot be half pregnant, you cannot be half encrypted once you install tools for scanning for certain content. There is a danger that we say, “We’re only doing it for those things”, but actually it would be an attack on encryption itself.
Unlike the noble Baroness, Lady Bennett of Manor Castle, I know nothing about the technical aspects of this, as noble Lords can hear from the way I am speaking about it. But I can see from a common-sense point of view what encryption is: you cannot say, “We’re only going to use it a little bit”. That is my point.
I want to tackle the issue of child abuse, because I know that it lurks around here. It is what really motivates the people who say, “It’s ok as long as we can deal with that”. This is put forward as a proposed solution to the problem of encrypted chat services that send messages of that nature and the question of what we can do about it. Of course I stress that images of child abuse and exploitation are abhorrent—that is a very important background to this conversation—but I want to draw attention to the question of what we are prepared to do about child abuse, because I think it was referred to in an earlier group. I am nervous that we are promising a silver bullet through this Bill that it will all be solved through some of these measures.

I noted that Professor Ross Anderson of the University of Cambridge said that we cannot expect artificial intelligence to replace police officers, teachers, and social workers in child protection. He said:
“The idea that complex social problems are amenable to cheap technical solutions is the siren song of the software salesman and has lured many a gullible government department on to the rocks”.
This is true. Most child abuse happens offline. Online child abuse needs to be dealt with, but I worry that we will say to people, “Don’t worry, all will be well because we’re dealing with it in the Online Safety Bill”.
