Abstract:

In order to study an information hiding technology of keyhole markup language (KML) file, an information hiding algorithm based on KML file is proposed. Firstly the difference between the characteristics of the KML document and the extensible markup language document is analyzed, and the status of the information hiding algorithm is studied. Then the information embedding algorithm and detection algorithm are proposed in KML file based on latitude and longitude coordinates. In these algorithms the values are classified by means of counting values for unimportant position, and then the information is hidden into the position which has been counted. The detection algorithm is the same as the embedding part, and information is extracted by using the classification. Experimental results show that the proposed algorithm has the higher robustness for resistance to addition and deletion attacks and rotation attacks on carrier data.
