In the UK a database has been set up that will make it possible to limit the number of duplicate pictures and quicker find links between the pictures. It is called CAID
"The CAID database is also part of a larger international effort called Project Vic that seeks to classify images held by forces around the world.Richard Brown from the International Centre for Missing and Exploited Children, which is helping co-ordinate Project Vic, said the two initiatives were using the same protocols to ensure images could be swapped back and forth easily.Seven other countries were already helping with Project Vic and more were expected to sign up soon, he said.
"It is groundbreaking for law enforcement, tool providers, non-profits and industry to all stand together and agree on the need to standardize the approach to such egregious crimes," Mr Brown told the BBC
standardizing could be done in many other sectors of cybercrime or malware
