| Abstract | ||
| Due to The increase of using the international network, the multimedia data security becomes the most significant factor to protect data. Encryption algorithms are covers some of data security requirement like confidentiality, prevent eavesdropping of data and integrity but the others requirements like copyright protection and data authentication which can be satisfy by sharing with another security technique which is called digital watermarking. So in this paper, digital watermarking and image encryption algorithm based on chaotic map are merging in one system to satisfy these objectives. The experimental results show The proposed scheme has a high security and, the correlation coefficients approach to zero(0.008) and high speed(0.5)second with good quality of extracted image after decrypted image(37dB). | ||
