i will not to use sql server for every one to use my application i need local file based database because my application is in CD password is more secure but with easy way can find it i can use sql server compact but installation is very long and my customer said installation is very long

You might want to consider SQL Server Compact. No one who uses your application will need to install anything since SSCE runs in your process. This way you get the superior database and security provided by SQL Server, without having to install SQL Server. SSCE still lets you use a local file as your database.

if you have 600 MB of data, it's better that use from another db like sql server or mysql.

if you want to use access, you can set a password for that and then in your connection string set your username and password.
