Hiding Encrypted Data In different image Types using spatial domain

Abstract

           The development of Informatics fields and data transfer through the internet increases daily. This development has emerged in the need to protect this data by developing cryptographic algorithms and concealment techniques to reach a higher level of protection. This work is developed using the Least Significant Bit (LSB). Focusing on changing concealment sites in the less important cells between points, and also using a suggested algorithm to encrypt grayscale image data by adopting the positivist method of image point locations. The algorithm was applied to more than one grayscale image and the data was hidden in more than one color image. The algorithm was approved and achieved good results after using metrics. The Peak Signal Noise Ratio (PSNR), The Mean Squared Error (MSE), and the Normalization Correlation (NC) standard measure the accuracy of extracted data.
