Recovering deleted browsing artifacts from web browser log files in Linux environment

In the present day scenario when it comes to Information interchange no one can even think about it without the use of Internet. Today there are uncountable numbers of websites in existence with loads of information present in them. To acquire this information one has to use a web browser in which these websites can be browsed according to our need. These web browsers store the users browsing history in specified log files which can be used in digital forensic investigation to acquire lots of information regarding the suspects browsing history. But these log files can be manipulated and cleaned by the users as and when required. In such a situation when suspects involved in any cyber crime deliberately cleans the traces of their browsing activity from any computer system further in depth examination of the crime becomes challenging and typical for the investigator concerned. This research is mainly focused on recovering such deleted browsing artifacts from the installed browser (Google Chrome in Linux environment) by an in depth analysis of the image of the hard disk used by the suspects involved in the crime.
