Steganography is the most used technique for data hiding. We can implement it using any cover media like text, images, and videos. In this paper we devised a new algorithm to hide our text in any colored image of any size using wavelet transform. It improves the image quality and imperceptibility. Our method sustains the security attacks. Extensive testing is performed using different sizes of ...

Steganography is data hiding technique that is mostly used. It uses cover object of type text, images, and videos. The paper presents a new devised algorithm to hide text in any colored image of any size using Huffman encryption and 2D Wavelet Transform. We presented simulated results which prove that there is very negligible image quality degradation. We used PSNR metric for this purpose. The ...

Day to day, network and its technologies is getting rapid growth, due to its improved infrastructure in to hold on; the situation organization and migration of recent updates will leads the network called Security flaw. Various security options are available since the data leakage and back door communication leads to heavy data loss to the organization. In this paper we developed a new scheme w...

Steganography is the dark cousin of cryptography, the use of codes. While cryptography provides privacy, steganography is intended to provide secrecy. Steganography is a method of covertly communicating. Steganography is a process that involves hiding a message in an appropriate carrier for example an image or an audio file. The carrier can then be sent to a receiver without anyone else knowing...

Steganography is a method for hiding information in a host signal. The host signal can be a still image, speech or video and the message signal that is hidden in the host signal can be a text, image or an audio signal. In this paper, a steganography method is proposed in which information hiding in the least significant bits (LSBs) of wavelet coefficients and also direct message replacement in ...

<strong><em>Steganography is a technique or art to hide secret message into cover so that the existence of cannot be known by other people third parties who do not have ability know contents message. The Least Significant Bit (LSB) method one methods used in steganography changing value rightmost bit stego with purpose this study was text an image using LSB method.</em></st...

In this paper, we analyze existing text-based steganography techniques, and propose an efficient information hiding algorithm for text based on substituted conception. In this algorithm, candidate units are replaced by similar conception, including synonym, homonym or special character. An improved encoding algorithm is also proposed which is not only enhances the robustness, but also enlarges ...

The rapid growth of online communication has increased the demand for secure communication. Most government entities, healthcare providers, legal sector, financial and banking, other industries are vulnerable to information security issues. Text steganography is one way protect by hiding secret messages in cover text. Hiding a high amount without raising attacker’s suspicion main challen...

The science of securing a data by encryption is Cryptography whereas the method of hiding secret messages in other messages is Steganography, so that the secret’s very existence is concealed. The term ‘Steganography’ describes the method of hiding cognitive content in another medium to avoid detection by the intruders. This paper introduces two new methods wherein cryptography and steganography...

Steganography is the science of hiding and communicating a secret message by embedding it in an innocent looking text such that eavesdropper unaware its existence. Previously, attempts were made to establish steganography using quantum key distribution (QKD). Recently, has been shown protocols are vulnerable certain steganalysis attack can detect presence hidden suppress entire communication. I...
