Abstract	:	Day after day modern and advanced techniques will be required to secure sensitive information against unauthorized access and attacks. Cryptography and steganography are well known as powerful techniquesused to secure sensitive data transmitted throughunsecured channels.However, the combination of these two methods will enhance the security of datatransmitted. Thus,this work aims to propose anew steganography technique which combining with a new encryption technique to providean extra level of security against attacks. The new technique apply on a BMP file format and itis designed based the Least Significant Bits (LSB) method to embed encrypted data into cover image. The experimental results in this work is executed by VB6 language. The image quality is measured in-terms of Mean square error (MSE) and Peak Signal to Noise Ratio (PSNR). Different host images have been tested with different sizes of files to be hidden. The results indicate thatthe new algorithmgives high PSNR and lower MSE values in all tested cases. Hence the proposed algorithm is very efficient to protect the vital information transmitted through unsecured networks.
