   Sammanfattning : Background. Coverless steganography is a relatively unexplored area of steganography where the message is not embedded into a cover media. Instead the message is derived from one or several properties already existing in the carrier media. This renders steganalysis methods used for traditional steganography useless. LÄS MER

3. 2. Text Steganalysis based on Convolutional Neural Networks

   Kandidat-uppsats, Blekinge Tekniska Högskola

   Nyckelord :CNN; text steganalysis; Deep Learning; Decision Strategy;

   Sammanfattning : The CNN-based steganalysis model is able to capture some complex statistical dependencies and also learn feature representations. The proposed model uses a word embedding layer to map the words into dense vectors thus, achieving more accurate representations of the words. The proposed model extracts both, the syntax and semantic features. LÄS MER
