摘要
En 中文
Advances in communication technologies have fueled growth in digital data transfer. Images are one of the most often conveyed types of digital information. Crytographic techniques help create cipher but also lure attackers as it indicates secret communication. To overcome, a method for encrypting a secret image and hiding it in audio data is proposed. The Ikeda map is used to create the encrypted image, which is then hidden in the audio's lifting wavelet transform. Various statistical experiments show that the proposed approach conceals the encrypted image while causing minimal changes to the audio. The proposed algorithm shows robustness towards noise addition or random audio crop attack by retrieving a visually perceivable image after the attack. The suggested approach outperforms the current algorithms in terms of imperceptibility and embedding capacity.
