How to add a password security to different records of a table

[Guest]

I have different customers in the database table.
The table is used to serve our client web page. How can I make sure that our
customers are only getting their specific information out of our database -
Or better how can I password protect each record in our database so that only
the permitted client can see his data?
Thanks
