Analyzing Different Digital Image Authentication Methods

A technique called authentication is used to protect photos, audio, and video files from unauthorized access. This study reviews various image authentication techniques. It divides various watermarking schemes into classes that are then further subdivided into different types. This study presents basic techniques that can be used by the attacker to destroy photographs along with important features and quality measuring matrices for image authentication. The limitations and research gaps are also highlighted, and discussed in the conclusion along with potential future directions.
