Diffusing the liveness
Weban anisotropic diffusion-based kernel matrix model (AD-KMM) for face liveness detection to prevent face spoofing attacks. The anisotropic diffusion method helps to dis-tinguish fake faces from real ones by diffusing the input image to enhance the difference in illumination character-istics. From these images, we can gain the depth informa- WebAbstract: While considerable research has been recently done in improving the accuracy of face liveness detection, the best current approaches use a two-step process of first …

WebMar 6, 2024 · Definition & General Overview. Liveness detection is a capability of a biometric system to differentiate falsified biometric traits presented to its sensors from the genuine ones. Liveness detection is, perchance, the central component in biometric security as it prevents fraudulent enrollment attempted with synthetic traits. WebThis paper proposes a spoofing detection method based on the diffusion speed of the input image. The diffusion speed. ... Widening a previous work, several stateof- the-art iris liveness detection methods were implemented and adapted to a less-constrained scenario. The proposed method combines a feature selection step prior to the use of state ...

Nonlinear diffusion is used in our face liveness detection to obtain the depth and preserve the boundary locations that help to distinguish a fake image from a real image by diffusing the input image quickly. Thus, the edges obtained from a flat image will fade out, whereas those from a real face will remain clear.
