Abstract:

 Webpage information hiding technology takes the webpage as covered channels to transmit the secret information. In this paper, an algorithm of webpage information hiding technology based on the tag dictionary was  proposed according to the webpage structure characteristics. The webpage information hiding capacity is increased by 25 times by using  the method of multiple tags combination without increasing the original webpage size and algorithm complexity. This provides a thought of webpage information hiding algorithm.
