Research on Information Disguising Technique to Protect DEM Data Based on Fuzzy Relation
Zhihong Xu · Mohu xitong yu shuxue · 2004
An information disguising technique that is used to protect DEM data is proposed in this (paper.) We construct Hash one-way by the Rabin method, and combine it with the wave equations (to create) DEM data stochastically. Then we built fuzzy matrix to make disguised DEM data. Only (authorized) users can restore the real data by the key K. The algorithm is public, and can be used (widely) in the concealed communication field.
