| Abstract | ||
| Abstract:In this paper, a new technique for hiding text in a bitmap images will be present. The technique based on using an index of the dictionary representing the characters of the secret messages instead of the characters themselves. The technique uses multiple frequency domains for embedding these indexes in an arbitrary chosen bitmap image. By using discrete cosine transform DCT, discrete wavelet transform DWT, and a combination of both of them. ِA software package for implementing this technique are built and we got very good results in terms of capacity of hiding, imperceptibility which are the most two important properties of steganography, the time of hiding the text, and the security issues. | ||
