Abstract

Many inconsistency analysis methods may be used to detect altered records or statements. But for admission as evidence, the reliability of the method has to be determined and measured. For example, in China, for evidence to be admitted, it has to have 95% certainty of being correct,1 and that certainty must be shown to the court, while in the US, evidence is admitted if it is more probative than prejudicial (a >50% standard).2 In either case, it is necessary to provide a measurement of some sort in order to pass muster under challenges from the other side. And in most cases, no such measurement has been undertaken. The question of how to undertake a scientific measurement to make such a determination, or at least to claim such a metric, is not well defined for digital forensics, but perhaps we can bring some light to the subject this issue.
