The latent functionality of the NGI system uses a Friction Ridge Investigative File consisting of all stored events for an individual as opposed to one composite image set per identity. This multiple events in the repository results in triple the accuracy of the latent search and allows additional event image retrieval to support difficult casework.
Before the NGI system, latent images in the criminal archive were searched. Now latent users can browse latent images using the criminal, civil, and unresolved latent file (ULF) repositories. In addition, incoming criminal and civil submissions (tens, palm, RISC and supplemental fingerprints) are forwarded to the ULF, generating new investigative leads in unresolved and/or unresolved cases. The CJIS department recommends that latent fingerprint images submitted prior to 2013 be resubmitted to the NGI system if no identification was made in the initial search.
In May 2013, the FBI established the National Palm Print System (NPPS). This system contains palm prints that can be searched for law enforcement agencies across the country. The NGI system also allows direct palmprint and supplemental fingerprint enrollment and deletion, similar to the existing direct fingerprint enrollment capability. These types of search and registry enhancements provide powerful new crime-solving capabilities for local, state, tribal, and federal law enforcement agencies across the country.
