The information is getting precious day by day because of the digital revolution and more reach exposure of citizens to technology. The security of information is in demand and the topmost priority among researchers to develop data security systems. Image steganography is one of the data hiding schemes which is invisible in nature, although it uses visible image media to hide information. Steganography is not only limited to images. There are other media like text, audio, or video that can be utilized for hiding information. In this research work, a novel data hiding is being developed using an image as cover media. Researchers are facing during the development of the technique is maintaining the payload capacity as well as higher PSNR values and other parameters. This work uses colour images as cover and digital bit modification methods to hide secure information. Only hiding is not enough to secure information. There is an additional layer of security added by encrypting a secure message using an encryption method. The digital bit modification method is unconventionally spread the sequential bitstream over channels. This would make this approach unique and better as it is keeping the PSNR level higher along with NCC and lower MSE. All this is done by keeping the payload capacity as the maximum available. The average value of PSNR is 60.295dB, NCC is 1.00, and MSE is 0.1567.
