The paper presents a new steganographic method called LACK (Lost Audio PaCKets Steganography) which is intended mainly for VoIP. The method is presented in a broader context of network steganography and of VoIP steganography in particular. The analytical results presented in the paper concern the influence of LACK’s hidden data insertion procedure on the method’s impact on quality of voice tran...

‘Steganography is a art, which enforcing for obscur one part of data or information within another’. this paper shown an image steganography scheme which based on neural network fusion in wavelet transform domain. The cover and stego image is dividing in its frequency coefficients components by wavelet transform domain, and neural network used as classifier. This paper performed on the 256*256 ...

Steganography is the technique of hiding confidential information within any media. Steganography is often confused with cryptography because the two are similar in the way that they both are used to protect confidential information. The difference between the two is in the appearance in the processed output; the output of steganography operation is not apparently visible but in cryptography th...

-Information Hiding is a method of hiding secret messages into a cover-media such that an intended observer will not be aware of the existence of hidden messages. In such applications various file formats are used as cover-object which contains confidential data. Steganography provide security and make safe the data of very important significance. Video Steganography is the technique of hiding ...

In recent times, many researchers have directed their research efforts towards increasing the privacy and security requirements in wireless communication networks area. The reason for this is inappropriateness of using traditional processes reliable, efficient, robust over that are not secured. Thus, study contributes to enhancement by proposing use steganography combined with cryptography so s...

Network steganography is a recently introduced, general term which describes all information hiding methods that may be used to hide secret data in the normal data transmissions of users. While sending encrypted information, enabled by some cryptographic algorithm, protects messages from being captured by unauthorized parties, steganographic techniques enable concealing the fact that a message ...

Steganography hides secret messages inside the covers while ensuring imperceptibility. Different from traditional steganography, deep learning-based steganography has an adaptable and generalized framework without needing expertise regarding embedding process. However, most algorithms utilize images as instead of videos, which are more expressive widely spread. To this end, end-to-end learning ...
