Protected implementation of image filtering in grid-systems

Markovskiy O.P., Nevdashenko M.V., Bilashevska A.V.

This paper proposes a method for protected implementation of image digital median and averaging filtering at remote processors of GRID-systems. Proposed methods ensures protection of image against unauthorized access while image network transmission and while image processing on remote computer systems. The methods for median filtering image protection is based on interval encryption and developed method for averaging filtering image protection is based on using of additional masking. The proposed procedure for image encryption and decryption are described in details. A numerical example for procedure image encryption and decryption for both type of image filtering are given.
