The Internet provides an ideal environment for users to communicate with one another. Digitized data can be transmitted over the Internet almost instantly. More and more confidential data has been delivered and the amount will keep on increasing. How to achieve the security of confidential data delivery is a very important issue in this digital era. Data encryption may help to ensure the cipher data is difficult to decode by an unknown user but it may not guarantee the delivery of the confidential data. Data hiding technique is a solution for confidential data delivery. In this paper, an HTML file is used as the cover medium for delivering confidential data. By utilizing the exibility of the HTML webpage creation, the proposed method uses different CSS attribute settings to encode the secret message. Because there are various ways to set the CSS margin and padding attributes, the proposed method not only helps to achieve the goal of secret data delivery but also provides a large embedding payload. The simulation results demonstrate that a CSS tag with margin and padding attributes can embed up to 112 secret bits.
