Presentation Attacks in Signature Biometrics: Types and Introduction to Attack Detection

摘要: Authentication applications based on the use of biometric methods have received a lot interest during last years due to breathtaking results obtained using personal traits such as face or fingerprint. However, it is important not forget that these systems withstand different types possible attacks. This work carries out an analysis Presentation Attack (PA) scenarios for on-line handwritten signature verification. The main contributions present are: (1) short overview representative Detection (PAD) in biometrics; (2) describe levels PAs existing verification regarding amount information available attacker, well training, effort and ability perform forgeries; (3) report evaluation system performance biometrics under writing tools considering freely databases. Results both BiosecurID e-BioSign databases show high impact only level attacker has but also training performing signature. line with recent efforts Common Criteria standardization community towards security systems, where attacks are rated depending on, among other factors, time spent, expertise used from target being attacked.
