cellphone number to email address
! Improve detection of crime e.g. online exploitation, phishing,
identity fraud
! Identify patterns in criminal behaviour

! Go undercover without being exposed to high risks

The Internet is a platform for new crime

The Internet can be a platform for new
crime-fighting

Dealing with the explosion
! Engage CSPs & online providers in a partnership to
develop solutions & tactics
! Make use of the data that is available for 2free3 e.g. open
