Text Hiding Using Text-Based Captcha Cover Image With Random Method

Abstract

Information Concealment is a task which facing difficult challenges today. This is due to the quick development of concealed information detection methods. The researchers, therefore turned their attention to the development of concealment information methods, become hard for the attackers to get secret information, like introducing a complex algorithm, using randomized methods, and inventing more challenging and complex steps. In this article introduced a new approach of concealment the information in the image. creates new series of challenging stages and mysterious through random bit distribution and the use of the encryption method. Then use the LSB technique to mask the bits within the image. The LSB technique was designed for making it harder to hiding the pixel. The presented results demonstrate the method’s robustness, safety and offer best protection for concealed information. Results displays the accuracy of stego image relative to original image by using the MSE and PSNR quality measurements.
