Make Your Webpage Carry Abundant Secret Information Unawarely

How to embed more secret message into Web page with keeping good imperceptibility simultaneously is a trade-off problem for information hiding schemes. This paper presents a novel Web page information hiding method based on three inherent features of current Web page´s HTML Code matrix. This method firstly exploits chaotic transform to deal with secret message, then embeds each bit of secret message into cover Web page according to the random odevity of character amount contained by each row(column) in cover Web page´s HTML code matrix. Its process is very simple to understand and easy to implement. It can improve the largest embedded capacity (LEC) of cover Web page greatly with keeping good imperceptibility at the same time. We test our approach on two test data sets which include 1000 Web pages in total. The experiment results show that the max LECs for these two data sets are up to 11291 bits and 13545 bits respectively. The average LECs for two data sets has improvement of 80.2% and 24% more than that of other Web page information hiding method .
