In recent times a lot of work has been carried out in the field of reversible data hiding (RDH) to prevent the secret data from theft, illegal copying and to provide copyright protection. In RDH the cover image will be recovered after extracting the secret data which was inserted in that image. This paper presents a new technique in reversible data hiding technique based on robust Firefly algorithm. The optimal location to hide the secret data will be found by firefly algorithm. The image scrambling is applied by Framelet Transform to prevent perceptual visibility of embedded secret image signal which increase the security level.2D bilateral filter is used to filter the image after hidden the secret information. The decomposition is done with Haar which is humble, symmetric and orthogonal wavelet and the direct weighting factor is used in secret embedding and extraction process.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
