“…The watermarks can be easily hidden into all forms of media document, including packaging, newspapers, posters, brochures, etc. [54]. Once an application is downloaded to the smart phone, we simply launch it, hold it parallel around 6″ from the printed content and the smart phone will directly detect the watermark and link then the customer to premium content online.…”

The digitization of audiovisual data is significantly increasing. Thus, in order to guarantee principally the protection of intellectual properties of this digital content, watermarking has appeared as a solution. The watermarking can be used in reality in several types of applications that target two different contexts; the first for security applications and the second for non-security ones. In this paper, we carry a big interest in studying these two types of applications. Moreover, we propose a first digital watermarking scheme for security copyright protection application where we have involved Neural Network architecture in the insertion and detection processes and we have integrated some masking phenomena of the Human Psychoacoustic Model with Linear Predictive Coding spectral envelope estimation of the audio file. Experimentations proved the efficiency of exploiting perceptual masking with spectral envelope consideration in terms of imperceptibility and robustness results. Besides, we suggest a second audio watermarking technique for non-security content characterization application based on deep learning classification architecture. In this scheme, extracted watermark will advise about the audio class: music or speech, the speaker gender and emotion. Reported results indicated that the suggested scheme achieved higher performance at classification level as well as at watermarking properties.

Abstract:The RTL-phenomena in quartz grains were initially reported and their properties and applications were developed by our group. Although RTL-measurements had the difficulty of overcoming high background counts due to blackbody radiation, the excellent dose linearity and hard-tobleaching nature of quartz RTL are suitable for accurate retrospective dosimetry and dating of burnt archaeological materials. In his paper, the discovery of RTL-phenomena is described. Subsequently, the construction and features of an automatic luminescence measuring system are mentioned together with innovative methods of decreasing the background level for the RTL measurement. Practical applications to dosimetry and dating are then described from the viewpoints of the preferable nature of RTL in comparison to other luminescence observations. Finally, some recent advances in RTL research are presented based on their emission mechanism correlated with impurity contents.
