The Dilemma of Digital Image Security: An Investigation Study into The Requirements and Techniques

Image encryption plays a paramount part to guarantee classified transmission and capacity of image over web. Then again, a real-time image encryption confronts a more noteworthy test because of vast measure of information included. This paper defines the digital image security requirements, and investigates the proposed mechanism from watermarking, steganography, and encryption algorithms. The conducted investigation aims to highlight the features, weaknesses, strengths, and limitations as well, and compare between these mechanisms in term of defined criteria.
