Recently, Televisions have been enhanced many new features base on the Internet standard. Television manufactories adopt web standards such as W3C and CSS to their products, so customers can customize their TV program likes a computer. This technology calls LINE Profiles. The profile includes a subset of XHTML, CSS, and ECMA Script that support more data applications for TV.  While XHTML support the TV background, CSS use to format the layout of the TV’s screen. ECMA Script includes the browser pseudo object functions such as communication using TCP/IP. In this article, the authors also list five requirements to link the TV program and LINE document received from the server:
1. Support a common control command to enable and disable datacasting (e.g. a datacasting button in the remote controller).
2. The Linear TV channel being transmitted must include a hyperlink descriptor in the SI (Service Information) tables.
3. When the datacasting button is pressed, the user agent requests the LIME document to the hyperlink address defined in 2.
4. The user agent receives the LIME content (document) which includes the ID of the Linear TV channel from the LIME content.
5. The screen is rendered with both the TV program and the enhanced datacasting content.

Sniffing Your History

by Jonathan F
There are a number of webs sites that can take a look at your browsing history. They are a number of them that are torrent sites and porn sites. It is easy to stay away from these kinds of sites but there are also a number of news sites that also track your browsing history. Research done at the University of California, San Diego found that 485 of the world’s 50,000 most popular sites have the capability of reading your browsing history. They do this by using a property of the Cascading Style Sheets language used for page layout. They use the “a; visted” property of (CSS) to their advantage. What this property does is that it changes the color of the links that you have visited and it is stored by the browser. What they do is that they put a bunch of invisible links to third-party sites on their site. Then they use JavaScript code to learn what color the invisible links are to figure out what sites you have visited, so if you have visited them then the color is different to the link. So from there they could create a list of sites that you have visited. The research shows that out of the 485 sites only 46 of them download that history and about 18 actually use it to analyze user visits to certain sites. History sniffing has been around for a while and it could be used to profile a person. There are people that think that its good because companies would only display advertising or links to sites that you would like based on your browsing history .They would only show you services or links that you tend to use.  The advice that is given by the article is to use browsers that prevent this, which are Chrome, Firefox, and Safari. Internet Explorer is secure only when using private browsing. read more...
