Security issue?

[font=verdana, arial, helvetica][size=2]Hi

Ive some questions about security issues in Flash MX 2004. If I use Flash with PHP and MySQL, how can I protect myself from that people wont get my Flash - movie from The Cache Memory and open it up. Ive heard there are som programs that can open Flash-movies even if they are protected with passwords used in Publish Settings. [/size][/font]

It could be a total disaster if someone coult take a look at the code and understand how my PHP-files communicate with the MySQL-server. Anyone having a good solution to this problem?
