Understanding and realizing the security and privacy challenges for information systems is a very critical and demanding task for both software engineers and developers to design and implement reliable and trustworthy information systems. This book provides novel contributions and research efforts related to security and privacy by shedding light on the legal, ethical, and technical aspects of security and privacy. This book consists of 12 chapters divided in three groups. The first contains works that discuss the ethical and legal aspects of security and privacy, the second contains works that focus more on the technical aspects of security and privacy, and the third contains works that show the applicability of various solutions in the aforementioned fields. This book is perfect for both experienced readers and young researchers that wish to read about the various aspects of security and privacy.

Nowadays, the technological advances allow developing many applications in different fields. In the book Colorimetry and Image Processing, two important fields are presented: colorimetry and image processing. Colorimetry is observed by a visual interactive programming learning system, an approach based on color analysis of Habanero chili pepper, an approach based on scene image segmentation centered on mathematical morphology, other systems based on the simulations of the dichromatic color appearance, and, finally, an approach based on the color reconstruction in order to enhancement its using super-resolution methods. On the other hand, image processing is shown by pansharpening algorithms for hyperspectral images, an approach based on the analysis of the low-resolution satellite images and ground-based sky camera for estimating the cloud motion, a hybrid super-resolution framework that combines desirable features of TV and PM models, a study of the real-time video analysis used for anthropometric measurements on agricultural tools and machines, and finally, an approach based on the threshold optimization iterative algorithm using the ground truth data and assessing the accuracy of a range of threshold values through the corresponding Kappa coefficient of concordance.

En el primer capítulo los investigadores estudiaron los niveles de eficiencia de 44 hospitales públicos del Departamento del Valle del Cauca, referente a los servicios de Ginecología y Obstetricia, Odontología y, Urgencias, entre los años 2007-2014. Los autores adoptan un método determinístico no paramétrico reciente, hasta ahora no aplicado en estudios científicos de salud en Colombia, el cual combina el Análisis de Eficiencia Multidireccional con otras relevantes técnicas, para comparar grupos con diferentes niveles de eficiencia. Realizando una aproximación más directa a la problemática de las instituciones públicas prestadoras de servicios de salud, y utilizando métodos de intervención financiera, el capítulo segundo hace referencia a la crisis económica del Hospital Universitario del Valle (HUV). Los autores se centran en la evaluación de las razones por las cuales el hospital llegó a la situación crítica que le obligó a solicitar el beneficio de la reestructuración contemplado en la Ley 550 de 1990.
