certainly yes it should be recorded with record of each section of correction made or alteration of data done, with timing & to be published time to time for public viewing.

People with Morals and Ethics will prevent or help in preventing corruption - one cannot expect that systems would help prevent corruption.

We can say it would helpful to make some confidence among people.... But what would be the actual impact on corruption will see in next few years... right now we can't make any conclusion for same as per my view...

Technology can at best make the work easier and effective. How it is used is primely important.

Contro : Same reason.
