This paper throws light on chaotic shift keying-based speech encryption and decryption
method. In this method, the input speech signals are sampled and its values are segmented …

Recently, merging signal processing techniques with information security services has
drawn a lot of attention. Steganography and steganalysis are among those trends. Like their …

Steganalysis of the quantization index modulation (QIM) steganography in a low-bit-rate
encoded speech stream is conducted in this research. According to the speech generation …

Speech signals convey various pieces of information such as the identity of its speaker, the
language spoken, and the linguistic information about the text being spoken, etc. In this …

Electric power load forecasting used to rely on some key information such as weather or
socioeconomic development data. However, it is usually difficult to obtain accurate data on …

During the last decade, audio information hiding has attracted lots of attention due to its
ability to provide a covert communication channel. On the other hand, various audio …

Steganalysis of the Quantization Index Modulation (QIM) steganography in VoIP (Voice-over
IP) stream is conducted in this research. VoIP is a popular media streaming and …

Linguistic steganalysis depends on efficient detection features due to the diversity of syntax
and the polysemia of semantics in natural language processing. This paper presents a novel …

Previous studies have shown that the underlying process of speech generation exhibits
nonlinear characteristics. Since linear features cannot represent a nonlinear system …

Quantization index modulation (QIM) based steganography allows concealing confidential
information in the Voice-over-Internet-Protocol (VoIP) speech streams. Cyber attackers and …
