How to prevent someone from copying secret data?

[simson]

hi,
I m wondering on strategy about preventing people from copying secret information. I think one of many solutions is :providing a flash *.swf file on my web page and protect it from downloading. For example: books.google.com. They hide books or comics very carefully, and i dont know how to download these things.
So, i just want to ask you for this solution or some solutions that you might know.
Moreover, my project uses j2ee.
Thank you!

Flash is by far the easiest and quickest way unless you are a master programmer. I tried this before with Flash and used a text doc that I linked to my .swf file. However, I had some issues with flash parsing the .txt file and more often than not it displayed as if it were not styled. XML might work better though.

Encryption? If it's secret, why publish it on the web?

It's trivial to extract information from flash files.

I understand simson. I am interested in finding the best ways to hide the code or to prevent many competitors to download my .swf , decompile it and adapt it on their own site. Hints and instructions for protection will be really appreciated. This is an experts forum but some of us are still learning.
