    Enhanced Lightweight Visual Cryptosystem (ELVC): Fortifying Cybersecurity for Visual Data Protection
    (SLIIT, Faculty of Engineering, 2024-10) Bhuvaneshwari, A. J; Kaythry, P.
    Within the field of cybersecurity, protecting visual data poses significant difficulties because of its extensive use and vulnerability to unwanted access. This article introduces the Enhanced Lightweight Visual Cryptosystem (ELVC), which is intended to strengthen cybersecurity by efficiently encrypting visual data. Using the Blake2 hash algorithm and advanced encryption techniques, the ELVC encrypts AC and DC coefficients, which are critical components in visual data compression. The encryption algorithm improves data security by calculating entropy, histograms, and PSNR values. Rigorous NIST performance tests demonstrate the ELVC's resilience to cryptographic weaknesses, ensuring its effectiveness in preventing cyber-attacks. The ELVC, which emphasizes both security and efficiency, is well-suited for deployment in resource-constrained situations like mobile and IoT devices. With its ability to protect visual data while maintaining quick processing, the ELVC stands as a noteworthy advancement in cybersecurity, offering heightened resilience against evolving threats.
