      El objetivo principal de este proyecto final de carrera ha sido la implementación de un algoritmo para el procesado de huellas dactilares. Todas las funciones han sido programadas en ANSI C utilizando el entorno de desarrollo ...

    • Almost separating and almost secure frameproof codes over q-ary alphabets 

      Moreira Sánchez, José; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2015-03-27)
      Article
      Open Access
      In this paper we discuss some variations of the notion of separating code for alphabets of arbitrary size. We show how the original definition can be relaxed in two different ways, namely almost separating and almost secure ...

    • Audio fingerprinting para la identificación automática de contenidos audiovisuales 

      Roca Navarro, Enrique (Universitat Politècnica de Catalunya, 2017-10-24)
      Bachelor thesis
      Open Access
      Audiofingerprinting is a technology used to identify audio files based on the content of the file. With them we can identify a pattern of an audio file, so that it can be recognized from an audio database, without having ...

    • Blocatge de rastrejadors web mitjançant tècniques d’empremta digital 

      Sánchez De Mingo, Óscar (Universitat Politècnica de Catalunya, 2021-06-28)
      Bachelor thesis
      Open Access
      Development of DTB+, a web-tracking blocker plugin which uses hashing techniques in web resources. The web resources the browser downloads are compared to a database of web- tracker fingerprints in order to block them. The ...

    • Business plan for a provider of access control systems based on fingerprints 

      Santos Leiva, Raul (Universitat Politècnica de Catalunya, 2010-10-26)

    • Constructions of almost secure frameproof codes based on small-bias probability spaces 

      Moreira Sánchez, José; Fernández Muñoz, Marcel; Kabatiansky, Grigory (Springer International Publishing, 2013)
      Conference report
      Restricted access - publisher's policy
      Secure frameproof code is the name given to a separating code when studied in relation to fingerprinting schemes. Separating codes are combinatorial objects that have found to be useful in many areas such as technical ...

    • Constructions of almost secure frameproof codes with applications to fingerprinting schemes 

      Moreira, Jose; Fernández Muñoz, Marcel; Kabatiansky, Grigory (2018-04)
      Article
      Open Access
      This paper presents explicit constructions of fingerprinting codes. The proposed constructions use a class of codes called almost secure frameproof codes. An almost secure frameproof code is a relaxed version of a secure ...
