R. Dhivya, N. Shanmugapriya · 2023
Many applications are available today that let us exchange images online. Only the intended receivers should have access to all of these images, which must be stored securely. Therefore, it is crucial to provide effective and quick methods for image encryption. This study introduced a kNN classification based Hybrid Chaotic encryption algorithm with combination of Discrete Wavelet Transform(DWT) with Discrete Cosine Transform(DCT) technique successfully reduce the computation cost for encryption The well-known real-world image dataset was utilized in the tests. The experimental results show that the proposed chaotic method of NPCR values of 99.812% also demonstrates that great pixel modification effects are attainable. The experimental data demonstrates that the proposed method outperforms than the existing Henon Map method.
