Detect texture details of the stego-image. The last image is the stego image. 1 Tools and Libraries used i. Then, the sparse signal gets extracted from the stego image, which is conversion to the binary form, and finally, the secret image gets extracted. The stego-key is the code that the person sending the secret message is going to use to embed the message into the cover object; the recipient to extract the secret message will use this same stego-key. RTA does not have this since their is no more detail to see by zooming.

Steganalysis techniques can be used to detect, extract, change or ultimately destroy the hidden information, and can be applied to suspect data for steganography, watermarking, or authentication purposes. The effectiveness of any steganographic algorithm depends on the embedding efficiency, embedding payload, and robustness against attackers. the stego images. This new hiding scheme utilizes a multiscale Laplacian pyramid of the cover image in the Discrete Wavelet Transform (DWT) domain. • For all other segments, new phase frames are created. For this project, confidential data was secured by using the least significant bit (LSB) algorithm. The Fast Fourier Transform (FFT) is a way of doing both of these in O(n log n) time.
