Since the 1970s, this international ignorance with respect to Colombian literature has gradually changed, primarily because of...

Uma Avaliação do Esquema de Gerenciamento de Chave Baseado em Identidade Identity Key Management

Security is one of the main issues in Mobile Ad Hoc Networks (MANETs). MANETs natural features make them highly vulnerable to several attacks ranging from the physical up to the application layer. There are several algorithms and protocols to deal with these threats. All of them have a common element, the use of cryptography. Among the cryptographic systems found in the literature, the identity...

Aplicação de sistemas imunológicos artificiais para biometria facial: Reconhecimento de identidade baseado nas características de padrões binários

This work aims to perform the identity recognition by a method based on Artificial Immune Systems, the Negative Selection Algorithm. Thus, the resources and adequate alternatives for analyzing 3D facial expressions were explored, exploring the Binary Pattern technique that is successfully applied for the 2D problem. Firstly, the 3D facial geometry was converted in two 2D representations. The De...
