Steganography using a 3 player game
Mehdi Yedroudj, Frédéric Comby, Marc Chaumont
Image steganography aims to securely embed secret information into cover images. Until now, adaptive embedding algorithms such as S-UNIWARD or Mi-POD, are among the most secure and…
Pooled Steganalysis in JPEG: how to deal with the spreading strategy?
Ahmad Zakaria, Marc Chaumont, Gérard Subsol
In image pooled steganalysis, a steganalyst, Eve, aims to detect if a set of images sent by a steganographer, Alice, to a receiver, Bob, contains a hidden message. We can reasonabl…
Deep Learning in steganography and steganalysis from 2015 to 2018
Marc Chaumont
For almost 10 years, the detection of a hidden message in an image has been mainly carried out by the computation of Rich Models (RM), followed by classification using an Ensemble…
PELICAN: deeP architecturE for the LIght Curve ANalysis
Johanna Pasquet, Jérôme Pasquet, Marc Chaumont +1
We developed a deeP architecturE for the LIght Curve ANalysis (PELICAN) for the characterization and the classification of light curves. It takes light curves as input, without any…
A CNN adapted to time series for the classification of Supernovae
Anthony Brunel, Johanna Pasquet, Jérôme Pasquet +4
Cosmologists are facing the problem of the analysis of a huge quantity of data when observing the sky. The methods used in cosmology are, for the most of them, relying on astrophys…
