[RESOLVED] How to secure local database? Encrypt/Obscurication/Compile?

Hi, i currently use an access password protected database to store my app data.

However there are several apps that can reveal access database passwords so i'm looking into securing the data, so if someone found out the database password the data would be scrambled.

My app regularly reads and writes to the database and i need something that isnt going to massively affect the speed of my app.

Can anyone recommend the best way to secure the data or recommend a different database type that is secure and compatible with all versions of windows?
