Digital audio is one of the most important types of data at present. It is used in several
applications, such as human knowledge and many security and banking applications. A …

Color image features extraction is an important and vital process, which is used in many
computer applications such as human fingerprint identification, therefore, shortening the …

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 …

The data may be very important and very confidential and when sent in an insecure
environment may be stolen or being snatched on them, which eliminates the importance and …

ABSTRACT A novel methodology to manipulate wave file and create a feature array for each
wave file will be introduced, this array can be used later on to recognize the voice file. A set …

Steganography and cryptography are very important techniques used in data security to
hide and secure secret messages in transmitted data. This paper will introduce, implement …

In this work, we present a novel approach for extracting features of a digital wave file. This
approach will be presented, implemented and tested. A signature or a key to any wave file …

Color image encryption-decryption is an important issue, because it is used in many
important applications. This paper will introduce 3 methods of image encryption-decryption …

Due to the large number of different computer applications transactions on the internet,
cryptography is a vital key in ensuring the security of the transactions. Cryptography is an …
