1. Evidence for "liveness" in face biometrics
Sammanfattning : Aliveness or "liveness" detection is a novel but crucial topic in biometrics. In this study we will investigate it for face biometrics. The problem is given by the real-time requirements of such a system to be able to avert advanced spoofing attempts, e.g. LÄS MER
2. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features
Sammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost. LÄS MER
3. Anonymizing Faces without Destroying Information
Sammanfattning : Anonymization is a broad term. Meaning that personal data, or rather data that identifies a person, is redacted or obscured. In the context of video and image data, the most palpable information is the face. Faces barely change compared to other aspect of a person, such as cloths, and we as people already have a strong sense of recognizing faces. LÄS MER
4. Audio-video synthesis methods for improving performance of biometric systems
Sammanfattning : System security is important for any automation. It is even more so in the case of biometric systems due to the sensitive nature of the data it uses for enrollment and authentication - the subjects physical or biological trait. LÄS MER
