Title in different languages: Fingerprinting: from a forensic perspective

Abstract: The identification of people in the forensic field is one of the principal goals that develops in an investigation. For instance, the dactyoloscopy plays an important role as it is an indispensable scientific method. A part from being very commonly used due to its veracity, speed and low cost. This system is based on the identification of friction ridges or papillary ridges of a footprint that has been fixed in a certain surface. In this project, it will be developed a perspective that allows us to know thoroughly this form of general science. It comes from its history, which was initiated in prehistory, but also the practical part through four real cases were the dactyloscopy has gained a great value. Also, the importance that the automated fingerprint identification (AFIS) has become apparent. What is more, it has improved this science especially in the speed of the method. Moreover, we should also highlight in this thesis the type of dactyloscopy that is used in the Spanish country, because each country uses its own methodology. It has been generally described, the physical and chemical developers that are more outstanding, so they are used depending on the surface in which the footprint is found or according to the conditions in which they are found. Finally, it has been proposed an investigation that will allow us to obtain accurate results when it comes to dating the footprints that we want to identify. Since in this way, we could get to know when was an individual at the scene. This advance would allow us, in a lot of cases, to have an increase of certainty that it was a certain person the one that has carried out the facts. Therefore, we could obtain a notion of when he did it.
