The phenomenal growth of e-commerce applications in the World Wide Web requires the need to increase the security of data communications over the Internet, especially for highly sensitive document transfer. Steganography techniques were introduced and developed to provide security to these applications.Steganography is a digital technique for hiding secret information into some form of media, such as image, audio or video. Steganography has evolved into a practice of concealing data in larger file in such a way that others cannot suspect the presence of a hidden message. This technique is generally used to maintain the confidentiality of valuable information to protect data from possible theft or unauthorized viewing. In this work, we present a new LSB-based steganography technique to embed large amount of data in RGBA images while keeping the perceptual degradation to a minimum. We propose to use the YIQ color space model to transform the RGB value of the secret image pixel into three separate components, which are then embedded into the least significant bits of each color pixel in the cover image, as well as in the alpha channel. Results obtained from simulation demonstrate that it is possible to attain practical hiding capacities up to 100% of the cover image while maintaining acceptable image quality.
