A Disguising Method for Linear Vector Data Based on Least Square Method

Linear vector spatial data has high economic and military value, and high-precision data in sensitive areas has important protection value. An information disguising method for linear vector data is introduced. Based on the characteristics of linear vector data, the basic principles and algorithm flow of linear vector data are analyzed. The data is compressed by D-P algorithm, and the information disguising of linear vector data is based on least square method. The experimental results show that this method has both security and bewilderment, meets the basic principle of information disguising of linear vector data, and can ensure the storage and transmission of important information.
