Optimization Of Secure And Efficient Encrypt Image Retrieval Based On Additive Sharing Using Smpc

Abstract

Due To Growing Threats Of Data Interception And Illegal Access, Secure Digital Image Transmission Over Open Networks Continues To Be A Major Concern. By Combining Elliptic Curve Cryptography (ECC), Visual Cryptography, And Least Significant Bit (LSB)-based Steganography, This Article Offers A Strong Framework For Safe Multi-image Transmission. Strong Encryption With A Smaller Key Size And Less Computational Cost Is Provided By ECC, Guaranteeing Effective And Safe Key Management. Visual Cryptography Is Used To Further Process The Encrypted Images, Breaking Each One Up Into Several Pieces That Don't Independently Give Any Useful Information. LSB Steganography Is Used To Embed These Files Inside Cover Images In Order To Improve Confidentiality. This Effectively Hides The Existence Of Sensitive Data During Transmission. The Original Images Are Recovered With High Fidelity At The Receiving End By Extracting The Embedded Shares, Reconstructing Them Using Visual Cryptography, And Decrypting Them Using ECC. Improved Peak Signal-toNoise Ratio (PSNR) Data Show That The Suggested Method Achieves High Reconstruction Accuracy, Minimum Visual Distortion, And Superior Security. Strong Defense Against Statistical Analysis, Cryptographic Attacks, And Illegal Access Is Offered By The Multi-layered Security System. All Things Considered, The Suggested System Provides A Scalable, Effective, And Extremely Secure Multi-image Transmission Solution, Making It Appropriate For Use In Defense Systems, Medical Imaging, And Secure Communications.
