Image Encryption with DWT: Secure and Visually Preserving

The hiding method of image encryption using Discrete Wavelet Transform (DWT) provides efficient encryption, a higher level of security, and resistance against attacks. By decomposing the image into frequency sub-bands, DWT-based hiding allows for effective encryption while maintaining the visual quality in low-frequency sub-bands. This technique ensures that the embedded secret data is indistinguishable, making it difficult for attackers to detect or extract the hidden information. Moreover, DWT-based hiding guarantees the integrity of the hidden data even when the encrypted image is subjected to common attacks such as noise addition or compression. In summary, DWT hiding is an effective approach for securely safeguarding sensitive information in images while preserving their visual quality.
