Abstract In this paper an information preservation upgrade framework is proposed for secure correspondence depending on reversible information covering through encoded pictures with reserve room method. This was actualized on real RGB picture under hold room method for multi scale disintegration. The Blue color was selected for concealing secure content information. The picture is diffused into local blocks and discrete wavelet is utilized to identify the estimation of gritty coefficients. The estimation part is scrambled by utilizing chaos based encryption technique. The suggested encryption system uses keys for image encoding in addition to improving the security of data bearer confidentiality by making the data challenging to access for any gatecrasher with an arbitrary technique. After encrypting the image, the information hider will disguise a mystery data into an itemized coefficient which are held prior to encryption. Despite encryption accomplishes certain safety impacts, it makes the mystery informations muddled and insignificant. The framework is as further improved with encoded messages by utilizing a symmetrical key technique. That is why our safety method is also known as reverse information covering. The art of secret correspondence involves hiding the current information in another medium. The method of information concealment uses flexible LSB calculations to hide a secret data bits in jumbled image. The mysterious data is removed in an information recovery setup by using the appropriate key to select the encoded pixel and separate the information. By utilizing the decoding key, the picture and extricated content info will be removed from encryption to get a first data. At last the effectiveness of the proposed encryption and information concealing method is examined dependent on picture and information recuperation.
