Image Enhancement Using Histogram Shifting Technique for Reversible Data Hiding

Digital image processing is the process of enhancing the clarity and quality of a picture. Also, owing to the requirement for security while emailing the recipient a picture. Reversible data hiding (RDH) is a key component of many current systems used to encrypt and decrypt pictures, allowing for easy improvement of the original image's quality without pixel loss once it has been embedded. Previous methods for embedding data into encrypted images by reversibly releasing space from them may have had drawbacks for data extraction and image restoration. Hence, by reducing data loss, this technique enhances picture security while also improving image quality at the receiver end. The rapid spread of information and the development of digital technologies, which have made it possible for information to be concealed in multimedia data, have made it easier to access digital data and made it possible for it to be stored, transferred, and processed in a reliable, quick, and efficient manner. This has had the unintended consequence of making it simple and covert to produce and distribute digital media illegally.
