A mobile phone application which claims to identify adults posing as children is to be released.
The team behind Child Defence says the app can analyse language to generate an age profile, identifying potential paedophiles.
Jon Taylor, a former police officer who is now an internet safety consultant told BBC Breakfast that attempts to groom children happen "within seven seconds" of a child introducing themselves in a chat room.
