The National Child Victim Identification Program (NCVIP) is the world's largest database of child pornography. This database is maintained by the Child Exploitation and Obscenity Section of the United States Department of Justice.
The Child Exploitation and Obscenity Section have joined forces with the National Center for Missing and Exploited Children for the purpose of finding out the identifies of children that have been abused.
Andrew Oosterban began developing this program in 1999, before it was launched in 2003. The database is filled with images from the United States customs Service, FBI, Secret Service, Postal Inspection Service, and numerous other organizations.
For security purposes, only higher up officers with security clearance are allowed to look at the database. Regular police officers are not allowed to manually browse the database, and they are unable to identify the victims by name.
When child porn is seized by police, investigators are responsible for inspecting the entire collection before submitting it to the database. In 2007 more than 10,000 images of child pornography were seized.
Two police officers were in charge of reviewing every single image.
