title: How to protect my SQL Server mdf/ldf files on the customer's PC?
body: <p>For some reason, I must save the SQL Server files (<code>.mdf</code> and <code>.ldf</code> files) on the customer's computer. But I don't want anyone to attach my database and see my data, except my application.</p>
  <p>Do we have any way to implement this requirement?</p>
