• Abstract: The Félix Pacheco Identification Institute (IIFP) is part of the General Superintendence of the Scientific Police of Rio de Janeiro - Brazil -, and  it is responsible for human identification through the analysis of fingerprints. This forensic activity takes place primarily through the use of an automated fingerprint identification system (AFIS) that searches the state's biometric database. Unfortunately, the number of unresolved traces analyzed is high, that is, when the person who produced that fingerprint is not in the databases to which the IIFP has direct access. Faced with this problem, the fingerprints analysis experts in Rio de Janeiro developed two improvement actions in order to solve the unresolved traces: internally, a new sector was created to analyze the unsolved cases accumulated over time, the cold cases, and, externally, a new active search routine for biometrics in other databases was established. In addition to the good local results, such actions allowed accelerating the signing of technical cooperation agreements to access different multibiometric banks whose integration and unification represent a serious problem in Brazil.
