Abstract: A new method of embedding a secret binary data in the Block Truncation Coded image shares is presented. The proposed scheme implements two of three threshold visual encryption. Error reduction is achieved by Floyd-Steinberg Error diffusion.
Keywords: Block Truncation Coding, Error Diffusion, Secret Sharing, Threshold Visual Cryptography.
Scope of the Article: Visual Analytics
