Image Encryption and Steganography Techniques

In the current era, the importance of image encryption and steganography techniques is self-evident. These technologies not only protect image security but also play crucial roles in information transmission. Image encryption techniques convert images into ciphertext, making them invisible to unauthorized personnel, thereby safeguarding personal privacy and confidential information through algorithms like AES (Advanced Encryption Standard) or RSA encryption applied to pixel data. Steganography techniques, implemented using methods such as LSB (Least Significant Bit) substitution or DCT (Discrete Cosine Transform) coefficient manipulation, embed one image within another, creating what appears to be an ordinary image on the surface but actually contains hidden information. This technology holds significant application value in intelligence fields and intellectual property protection, often involving sophisticated embedding algorithms and extraction routines. Therefore, there's an urgent need for image encryption and steganography techniques today, as they play irreplaceable roles in protecting personal privacy, safeguarding confidential information, and preserving intellectual property rights through robust digital security implementations.
