March2022 MarkS.Nixon ProfessorEmeritus SchoolofElectronicsandComputer Science UniversityofSouthampton Southampton,UK Preface The study of Presentation Attack Detection (PAD) is now an established field of research across the biometrics community.

Thetremendousadvancessincethepublicationofthesecondeditionin2019are the principal reason why we decided to compile a third edition of the Handbook of Biometric Anti-Spoofing. As for the second edition, we published an open call for expressions of interest and invited updates to previous chapters in addition to entirely new contributions. The third edition is arranged in seven different parts dedicatedtoPADinfingerprintrecognition,irisrecognition,facerecognition,and voicerecognition,withtwomorecoveringotherandmulti-biometrics,legalaspects, andstandards.Likethesecondedition,thefirstfourpartsallstartwithanintroduction to PAD that is specific to each biometric characteristic. We are delighted that all four also contain a review of PAD competitions (the last being combined with the respectiveintroduction),allupdatedtoprovideanoverviewofprogressandthelatest results. New chapters feature throughout and complement updates with coverage of new detection approaches and models, multi-spectral/multi-channel techniques, multiple biometric PAD databases and solutions, and legal perspectives. The third editioncomprises21chapters.Weareextremelygratefultotheauthorsandalsothe reviewerswhohavehelpedtoensurequality.Bothauthorsaswellasreviewersare listedseparatelyherein.
