| Abstract | ||
| Abstract In this research a simulation parallel algorithm for data hiding and data retrieval in gray digital image files were used. A simulation for this algorithm was applied on star network type. The secret image and the covered image was segment in equal number of parts (four parts) then was applying the suggested algorithm on each part in synchronized form using Matlab Parallel Processing Tools. The proposed algorithm was applied to retrieve the secret image from the covered one in synchronized form too. Measurement of time needed by the algorithm was compared with one used serial algorithm for hiding and retrieving by using substitution techniques. The proposed algorithm shows higher performance than the serial type in consuming time. | ||
