Chaotic Map Based Raster Data Encryption for Geospatial Data

Data confidentiality, security authentication are just some of the many uses for image encryption, making it one of the most effective methods for safeguarding geospatial data.However, even with advancements in an encryption algorithms still face challenges in terms of both security and speed.However, limitations in key space, complexity of algorithms, make it susceptible to assaults plague present in image encryption methods.Considering the restrictions of past strategies, we've formulated a brought together way to deal with raster data encryption by consolidating shuffled raster Output, Chirikov and Chebyshev chaotic map.At the point image is the constant raster is first shuffled by shuffling method to muddle the pixels of each block.The randomization characteristic in keys generated by Chirikov and Chebyshev Chaotic maps will be used to encode raster data.Encryption is performed rapidly utilizing the recommended approach.The reenactment results exhibit the adequacy and reasonableness of the method for safeguarding raster geospatial data.
