    AAC compression detection based on scaling factor transition probability by Qijuan HUANG, Rangding WANG, Diqun YAN

    Published 2017-11-01
    “…Audio compression history detection is an important part of audio forensics,which is important to detect whether audio has been tampered or forged.An algorithm of AAC audio compression history detection was presented by using the transition probability differences of scale factors as the discriminative feature.Experimental results demonstrate that the proposed method can distinguish the single,double and triple compressed AAC audios effectively,and from the low-bite-rate to high-bit-rate,the average classification accuracy achieves 99.75%,the same-bit-rate detection accuracy achieves 97.28%.In addition,the results of comparison experiments show that the proposed algorithm outperforms the state-of-the-art algorithm.…”

    La parole de l’enfant victime de crimes sexuels dans les procédures judiciaires aux Assises de la Charente (1889-1914) by Marie Rougier

    Published 2020-03-01
    “…In a context of a child welfare emerging from the end of the 19th century and paradoxically the development of theses supported by forensics on the mythomania of children in cases of indecent assault, this article proposes to question the place given to the speech of the child victim of a sexual crime with his depositories, and then throughout the investigation process.To achieve this objective, this study is based on the systematic counting of 68 procedural files of cases of rape, indecent assault and incest committed on minors and judged by the Court of Assizes of Charente, courts of Angoulême, Cognac, Barbezieux and Confolens from 1889 to 1914 and the exploitation of the charges, police or gendarmerie minutes, interrogations of investigating judges, hearing witnesses and medicals expertises.…”

    Video inter-frame tampering detection algorithm fusing multiple features by Hui XIAO, Bin WENG, Tianqiang HUANG, Han PU, Zehui HUANG

    Published 2020-02-01
    “…Traditional passive forensics of video inter-frame tampering often relies on single feature.Each of these features is usually suitable for certain types of videos,while has low detection accuracy for other videos.To combine the advantages of these features,a video inter-frame tampering detection algorithm that could fuse multi-features was proposed.The algorithm firstly classified the input video into one group based on its space information and time information values.Then it calculated the VQA features that represented the video inter-frame continuity.These features were sorted by the SVM-RFE feature recursive elimination algorithm.Finally,the sorted features were filtered and fused by the sequential forward selection algorithm and Adaboost binary classifier.Experimental results show that the proposed algorithm could achieve higher tampering detection accuracy.…”

    Video tampering detection algorithm based on spatial constraint and gradient structure information by Han PU, Tianqiang HUANG, Bin WENG, Hui XIAO, Wei HUANG

    Published 2019-10-01
    “…The traditional video passive forensics method using only the principle of similarity between adjacent frames will cause a lot of false detection for the video with severe motion.Aiming at this problem,a video tamper detection method combining spatial constraints and gradient structure information was proposed.Firstly,the low motion region and the high texture region were extracted by using spatial constraint criteria.The two regions were merged to obtain the robust quantitative correlation rich regions for extracting video optimal similarity features.Then improving the extraction and description methods of the original features,and using the similarity of the gradient structure in accordance with the characteristics of the human visual system to calculate the spatial constraint correlation value.Finally,the tampering points were located by the Chebyshev inequality.Experiments show that the proposed algorithm has lower false detection rate and higher accuracy.…”

    A Extinção da Ordem do Templo em Portugal by Saul António Gomes

    Published 2011-11-01
    “…Procede à edição de documentos não publicados integralmente, até ao momento, muito em especial a inquirição levada a cabo por João Pais de Soure, em 1314. Inquirição forense controlada por oficiais ao serviço da Coroa, consequentemente acto documental isento de vício ou de suspeição à partida favorável aos templários, ela permite verificar, mau grado episódios de tensão entre o poder régio e a Ordem, a prevalência estrutural, na memória histórica dos templários portugueses, dos sentimentos de auxílio e de lealdade dos cavaleiros portugueses desta Ordem para com o rei. …”
