PC Sentry is an institute level, Server based project. It is a combination of two different functionalities namely
1. Desktop locking
2. Internet filtering
1.Desktop locking :
Every user in the institute has an individual User Profile. Every time a user starts the PC, he is forced to login before he is given the access to the system. His login information is checked from the user’s database for its appropriateness. If he is an authorized user he is given the access to system.
2. Internet filtering:
PC sentry is a server based project i.e. it is installed on the server through which all the communication takes place. Every time a user requests for a URL, It is checked to find if it is objectionable. This checking is done in 3 steps :
1.)In the first step the URL is checked against the database of objectionable sites. If the site is not in the list.
2) In the 2nd step it is checked against the keyword database to find any objectionable word in the URL. Suppose the site is not blocked
3) In the 3rd step the text contents in the web page are checked to find if there is any porn keyword. If the search result exceeds the predefined limit then the site is blocked.
If the site is blocked in any of the three steps then a “ PAGE NOT FOUND” massage is displayed.]
