Secure RGB Image Steganography from Pixel Indicator to Triple Algorithm-An Incremental Growth
نویسندگان
چکیده
Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. In this paper we have investigate two methods of RGB image steganography one is pixel indicator technique and other is triple-A algorithem.They uses the same principle of LSB, where the secret is hidden in the least significant bits of the pixels, with more randomization in selection of the number of bits used and the color channels that are used. This randomization is expected to increase the security of the system and also increase the capacity. These techniques can be applied to RGB images where each pixel is represented by three bytes to indicate the intensity of red, green, and blue in that pixel. This work showed attractive results especially in the capacity of the data-bits to be hidden with relation to the RGB image pixels.

Edge Adaptive Image Steganography Based on Variable Embedding
Steganography is the art of hiding information in a manner that its very existence is not known. Unlike cryptography which only scrambles the content of the message so that it cannot be read, steganography is a more secure method as it hides the very existence of the message. This paper proposes a new image steganographic technique that embeds secret data only in the edge regions of the cover i...
متن کاملA Secure Image Steganography Based on RSA Algorithm and Hash-LSB Technique
Steganography is a method of hiding secret messages in a cover object while communication takes place between sender and receiver. Security of confidential information has always been a major issue from the past times to the present time. It has always been the interested topic for researchers to develop secure techniques to send data without revealing it to anyone other than the receiver. Ther...
متن کاملA Methodology to Conceal QR Codes for Security Applications
Steganography is a technique used to conceal information in such a way that only the communicating party would know about the existence of the information. In this paper, Steganography is used to embed an encrypted QR Code into an image. The QR Code is encrypted using Triple DES algorithm in order to increase the level of security. The overall approach presented in this paper could potentially ...
متن کاملWeighted median algorithm applied to steganography in RGB images
In this paper, we present a novel method for hidden information in the wavelet domain. The proposed method uses the wavelet domain iterative center weighted median algorithm to estimate the noise areas of an RGB image. We propose to use the noise pixels as places to hidden information to provide good invisibility and fine detail preservation of processed images. The proposed method consistently...
متن کاملA Novel Image Steganography (NIS) Technique
With the growth in the communication, there is an increase in the transmission of data across the various medium; security is the key issue that needs to be addressed. Various steganography techniques are used to hide actual message secretly to provide control over the medium where data is sent. This paper is intended to propose an image steganography technique that will hide four bits of data ...
