Image Encryption GUI with MATLAB Implementation

This MATLAB program provides a comprehensive solution for image encryption with an intuitive GUI design. The implementation includes customizable encryption algorithms where users can modify core cryptographic functions (such as AES or RSA implementations) through parameter adjustments in the encryption module. The system supports multi-layer encryption through nested function calls, allowing additional security layers to be programmatically added via a layer management interface. Key technical features include built-in image compression/decompression utilities utilizing discrete cosine transform (DCT) algorithms, and an encrypted image database manager that handles file I/O operations using MATLAB's image processing toolbox. The object-oriented architecture employs callback functions for GUI components, ensuring seamless interaction between the frontend interface and backend encryption processing. Whether for personal privacy protection or cryptographic algorithm development, this program offers robust functionality through its modular MATLAB code structure.
