An investigator wants to know if an illicit image captured by an unknown camera was taken by a person of interest’s (POI’s) phone. Score-based likelihood ratios (SLRs) have been used to answer this question in previous research. We explore whether the reference set used to calculate SLRs makes a difference in the outcome when the questioned image comes from a phone of the same model as the POI’s phone.
