Medios de comunicación y neoliberalismo en Argentina

En este trabajo se utiliza una muestra de noticias desde 2015 a 2019 procedentes de tres de los principales periódicos argentinos y de algunos medios de comunicación digitales del mismo país para desarrollar una reflexión sobre la relación entre mass media y poder. Los resultados sugieren que la prensa es un brazo de las políticas de lawfare aplicadas en Argentina al servicio de implementar políticas neoliberales y en desmedro del régimen democrático. La oposición política y los llamados líderes populistas han sido sistemáticamente descalificados, ridiculizados y calumniados. Mientras, con un poderoso ariete comunicacional se logró instalar en la presidencia de Argentina en el año 2015 a Mauricio Macri, un personaje con una carrera política breve y numerosos escándalos en su historial que lo vinculaban con el contrabando, las escuchas ilegales y la corrupción.

Modern technology has provided us with unlimited possibilities for audio and visual recording, which can, unfortunately, also be used for the violation of human rights and freedoms. With the agreement of involved parties, the use of the recording is likely to be uncontroversial. However, complex issues arise when the recording is covert, and when the recording party wants to rely upon the recording, or the transcript of it, to prove an illegal act in court proceedings. The question arises as to how to strike a balance between the need to protect security and investigate the truth and the need to protect the right to privacy and the personal sphere. Particularly interesting legal issues are those that concern the justification and the permissibility of the use of illegal or covert recordings in the capacity of evidence in criminal proceedings. Bearing in mind the above, the paper is devoted to the analysis of legislation concerning protection of privacy and the legislation on the subject of illegal evidence in criminal proceedings. This issue is especially interesting due to the fact that Serbian criminal law accepts the theory of "the fruits of the poisonous tree", which means that the criteria for the evaluation of the validity of the evidence are particularly strict. In that context, the normative, axiological and comparative law method has been used to analyse the subject matter. The author has also referred to the comparative law and to the practice of the European Court of Human Rights. The aim of the paper is to point out to the certain ambiguities in Serbian positive law, in order to develop appropriate recommendations for the practical use and for the improvement of normative solutions.

A fast video watermarking algorithm using dual tree complex wavelet transform

Illegal camcording as the most common source of video piracy, is the main concern of the film production companies. With the increased speed and convenience of access to the Internet and video sharing services, the distribution of pirated video copies is more than easy. Digital video watermarking is one of the possible ways to prevent the illegal recording and distribution of videos. In this paper, a blind digital video watermarking method based on Dual-Tree Complex Wavelet Transform (DTCWT) is proposed. Here, the generated watermark is embedded in the low frequency coefficients of the chrominance channel of the video frames. The watermark is generated in a way that the detection system does not need to know the size of the original video. To reduce the computational complexity of the proposed method, the embedding process is equivalently done in the spatial domain. The proposed method is compared to the state-of-art methods against different attacks. Experimental results show that the proposed method is more robust against various attacks while maintaining the perceptual quality of the original video significantly better than the compared methods. Also the proposed method is evaluated in terms of computational complexity which reveals that the proposed method performs faster than the compared methods.

A brand new application of visual-audio fingerprints: Estimating the position of the pirate in a theater - A case study

Combating against camcorder piracy requires identification of the theater and show time information, followed by the estimation of camcorder location in a theater from which an illegal recording was made, in order to find out the pirate and limit the number of pirate suspects. State-of-the-art pirate position estimation frameworks employ watermarking techniques to approximate the position of the pirate in a movie theater. However, watermarks are fragile in nature and involve complex procedures, which may damage the video content. To solve this, a novel forensic tracking framework, which exploits visual-audio fingerprints for estimating the location of the pirate in a theater without embedding digital watermarks is presented. Precisely, the proposed framework first spatio-temporally aligns the source movie and captured video contents, then estimates the geometric distortions and consequently derives the illegal capture location in a theater by exploiting multimodal features. The case study results in the form of sophisticated In-theater experiments prove that, it is certainly possible to estimate the illegal capture location in a theater with a mean absolute error of (38.25, 22.45, 11.11) cm, by employing multimodal fingerprints. In this way, the proposed article demonstrates a brand-new application of video fingerprinting for investigating the location of illegal camcorder capture in a theater, which is applicable for digital cinema applications.
