AbstractIn this work, anew hiding algorithm is proposed that depends on using two deferent domain (spatial and frequency) to achieve and provide security and protection for transformed data, which is represented in a text message encrypted using a key of direct standard method, then spatial domain were use to hide it inside an audio file, Using Discrete cosine transform (DCT) this file has been hidden inside a host audio file. The data of the text message has been fully retrieved after decrypting process, the value of normalization correlation is equal to one.
