A great deal of work has recently been done in the field of reversible data hiding( RDH) to prevent theft of secret data, illegal copying and protect copyright. In RDH, the cover image is recovered after the secret data inserted in the image is extracted.This paper presents a new reversible technology for data hiding based on a robust Firefly algorithm. The optimum location for hiding the secret data is the firefly algorithm. Framelet Transform applies image scrambling to prevent perceptual visibility of the embedded secret image.. After secret information is hidden, the 2D bilateral filter is used to filter an image. The decomposition is done with a humble, symmetrical and orthogonal wavelet hair and the direct weighting factor is used in the secret process of embedding and extraction. The hidden image becomes computationally high memory data. The image must be compressed by the SPIHT image compression algorithm during transmission.
