Research on the confidentiality oriented image slicing and recovering system

Abstract

As information technology continues to progress, images, video and other multimedia files are widely transmitted over internet. Security threats like Viruses, Trojans, hackers hinder the application with data especially image exchange. Regarding this problem, an image sharing algorithm is proposed, and the matrix multiplication is used for image slicing. The original image can be recovered only when more than certain number of encrypted slices are collected and processed. The simulation experiment proves that the algorithm proposed can recover the image without loss of quality from qualified slices and any slices less than the threshold can not recover the image. © 2013 Springer-Verlag.
