An Efficient Image Encryption Reversible Data Hiding Technique to Improve Payload and High Security in Cloud Platforms

Researchers are becoming more intrigued by images (RDHEI) since of its potential applications in areas like privacy protection and cloud storage. If you need to include more information in the encrypted domain, RDHEI is a useful method that won’t compromise your security. An RDHEI technique is proposed in this paper, which is both fully reversible and capable of embedding a large payload. Once the content owner has encrypted the original picture via homomorphism encryption, the hider may insert the secret statistics into the encrypted portion of the image. Privacy may be protected via the use of data concealing in images. It employs a slew of deceptive techniques to conceal sensitive information. Heavily altering a histogram may make hidden information much harder to find. Additionally, the data is not expanded during homomorphism encryption, and the payload is still capable of being enhanced. The recipient of the encrypted watermarked picture needs just the data concealing key in order to access the hidden information. To decode a picture, all the recipient has to know is the encryption key. Having both the data concealing key and the encryption allows the receiver to decrypt the picture and restore the original data without any quality loss. The receiver will be able to decipher the secret communication and restore the unique picture with zero quality loss. The experimental results demonstrate not only an enhancement of the embedding payload, but also an exact extraction of the concealed data and a complete retrieval of the cover picture.
