Data hidding in color images using perceptual models
(Christian Germain, Eric Grivel, Olivier Lavialle, 2000)
Text en actes de congrés
Accés obertOne of the problems arising from the use of digital media is the ease of identical copies of digital images or audio files, allowing manipulation and unauthorized use. Copyright is an effective tool for preserving ... -
Detection of replay attacks in CPSs using observer-based signature compensation
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Text en actes de congrés
Accés obertThis paper presents a replay attack detection method that addresses the performance loss of watermarking-based approaches. The proposed method injects a sinusoidal signal that affects a subset, chosen at random, of the ... -
Digital watermarking techniques and security issues in the information and communication society
(CRC Press and IEEE Press, 2013)
Text en actes de congrés
Accés obertDigital watermarking is the process of embedding information into a noise-tolerant digital signal such as image or audio data. Such information is embedded in a way difficult to be removed in order to easily identify ... -
Estudio de los códigos turbo como códigos fingerprinting
(Universitat Politècnica de Catalunya, 2010-10-15)
Projecte/Treball Final de Carrera
Accés obertLos objetivos que se deberán alcanzar una vez nalizado este proyecto son los siguientes: La realización de una plataforma de codi cación - decodi cación turbo que permita simular la robustez de estos códigos frente a ... -
Estudio de técnicas de inserción de marcas de agua sobre software
(Universitat Politècnica de Catalunya, 2008-06-25)
Projecte/Treball Final de Carrera
Accés obertEste trabajo es un estudio de las distintas técnicas de software watermarking existentes para la protección de la propiedad intelectual contenida en un programa. Partiendo de este estudio se propone una implementación para ... -
Optimum watermark detection in color images
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertThis work concentrates on the problem of watermarking embedding and optimum detection in color images through the use of spread spectrum techniques both in space (Direct Sequence Spread Spectrum or DSSS) and frequency ... -
Perceptual masks in the wavelet domain for color image watermarking
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, three different perceptual masks in the wavelet domain are investigated for image watermarking systems. Along with an already existing method, we present two alternative perceptual masks based on visual ... -
Reversible fingerprinting for genomic information
(2020-01-03)
Article
Accés obertNew genome sequencing technologies have simplified the generation of genomic data, making them more common but in turn a likely target of attack. Security strategies have been devised such as restricting the amount of ... -
Robust error detection methods for H.264/AVC videos
(Universitat Politècnica de Catalunya, 2008-09-23)
Projecte Final de Màster Oficial
Accés obertThe 3rd generation of mobile systems is mainly focused on enabling multimedia services such as video streaming, video call and conferencing. In order to achieve this, the Universal Mobile Telecommunications System (UMTS), ... -
Robust watermarking techniques for authentication of printed copies through digital camera capture
(Universitat Politècnica de Catalunya, 2013-03-08)
Projecte Final de Màster Oficial
Accés obertWithin the digital processing field, the aim of this thesis is to validate a robust image watermarking method and, afterwards, the authentication of these watermarks when images are printed and captured by a digital ...
