Data security - help required

[Ratheesh K J]

Hello all,

I have a requirement of maintaining some secret information in the database. And this
information should not be visible/accessible to any other person but the owner of the
data.
Whilst I know that encryption/decryption is the solution for this, are there any other
level of security that I can provide to this?

Which is the best security technique used in MySQL to store seceret information.

PS: Even the database admin should not be able to access anybody else's information

Thanks
