The identification of living persons on images: A literature review

• Recently there has been an increase in cases of identification of living persons, especially from surveillance systems.
• Identification of the living persons is based on the knowledge of methodological approaches and respective limitations.
• This review requires the issue of personal identification using different body structures.
• Recommendations are given in order to aid forensic practitioners in cases of identification of living persons.

Personal identification in the forensic context commonly concerns unknown decedents. However, recently there has been an increase in cases which require identification of living persons, especially from surveillance systems. These cases bring about a relatively new challenge for forensic anthropologists and pathologists concerning the selection of the most suitable methodological approaches with regard to the limitations of the photographic representation of a given person for individualization and identity.Facial features are instinctively the primary focus for identification approaches. However, other body parts (e.g. hands), and body height and gait (on videos) have been considered in cases of personal identification.This review aims at summarizing the state-of-the-art concerning the identification of the living on images and videos, including a critical evaluation of the advantages and limitations of different methods. Recommendations are given in order to aid forensic practitioners who face cases of identification of living persons.
