Common questions
What is EvoFinder and how does it differ from IBIS?+
EvoFinder is a ballistic identification system developed by Evofinder Ltd. in the UK. It uses a different optical acquisition method and algorithm than IBIS. Both systems aim to match bullets and cartridge cases to crime scenes and suspect firearms, but they approach the technical problem differently.
Where is EvoFinder actually used?+
EvoFinder is deployed in jurisdictions without existing IBIS infrastructure. This makes it a practical option for regions that built their ballistic comparison systems independently or needed an alternative to the established system.
Can EvoFinder compare images from IBIS databases?+
Not directly. Cross-system interoperability between EvoFinder and IBIS remains an open technical and policy challenge. A bullet imaged on one system cannot yet be automatically compared against images from the other, which limits collaborative investigative work across jurisdictions.
