Abstract - Steganography is an information security technique that provides a solution for hiding information. There are different

types of cover mediums that can be used in steganography such as text or image steganography. We chose image steganography

as our domain of work where the images are used as cover mediums to be our basis of experiments for the proposed LSBG method.

One of the main well-known steganography methods is the least significant bit (LSB), however it has its limitations and therefore

many approaches have been proposed to improve it. We propose a new improvement method defined as Least Significant Bit

Gaped (LSBG) where the aim is to improve steganography imperceptibility compared to LSB by comparing the histogram analysis

of LSB with LSBG methods and MSE measures. The proposed LSBG method will also offer a new key structure that will increase

the complexity in secret data extraction and the level of information security.
