In this research, we present a new method for protecting confidential and private data, which
combines the two processes of data cryptography and data steganography. The data …

The purpose of steganography is to conceal the existence of the secret message in the
holding image, thus making a message unreadable by a third party. Steganography is an …

Data compression is a process of reducing the data size to minimize the storage size and
the data transmission time, will decompression means recovering the original data without …

Data steganography is an important process, which is needed in various human life
applications, so the need for efficient method of data hiding is vital issue. In this paper we …

Average and median filters are the most popular filters used to reduce the negative effects of
salt and pepper noise affected gray and color images, these filters work good when the …

Least significant bit method is one of the most popular methods of data steganography, this
method is very simple and provides good values for MSE and PSNR. LSB method is not …

Digital image is an important data type due to the wide applications requiring this data type.
