Abstract
En 中文
Securing data during transmission is critical to prevent unauthorized access, interception, or modification of the data. Data can be communicated securely while maintaining its confidentiality, integrity, and availability by using cryptographic algorithms and measures. In the proposed work, a hybrid data compression algorithm is proposed to increase the amount of input data that is encrypted using the Advanced Encryption Standard (AES) cryptography method to boost security level, and it can be utilized to carry out the lossy compacting Steganography method. By reducing the quantity of data transmitted, this technique can enable speedy transmission over a sluggish internet connection or use less space on different storage devices. The cover image is compressed using Discrete Wavelet Transform (DWT), which reduces the cover image's dimensions by lossyly compressing the image. The ordinary text is converted to hexadecimal format from text. The encrypted data will then be inserted into the compressed cover picture using the least significant bit (LSB) with Image vector array (IVA). Bits per pixel (BPP), Mean Squared Error (MSE), Peak Signal to Noise Ratio (PSNR), and Structural Similarity Index (SSIM) were some of the metrics we used to evaluate the proposed technique.
