Hey the same Problem with me too....

I got an Solution....

The Solution is Dual Passwords :D

Here all we can do is encrypt all the data that is confidential...

Step 2 : You can encrypt all the data using a Password that may be 1 or 2...

Step 3 : to decrypt that data again the same password must be used..

THE PROBLEM SOLVED: The problem is how Can we store the Passwords in the database..

3. continue to next
4. Beware decrypt all the data before you present to user.....
