[flexcoders] shared object security with flex 1.5

[Robert Brueckmann]

I created a "remember me on this computer" option when the user logs in, so when they come to the URL it automatically logs them into our site based on the username and password I'm encrypting and storing in a shared object on their machine.  Works great.   Out of curiosity, I located that actual shared object file and emailed it to my coworker and had him install it in the similar location on his machine and when he went to the website, it automatically logged him in as me.    Is there any way to prevent this from happening?  I mean, what additional security could I add to prevent (if the user does, for whatever conceivable reason) the copying of the .sol file from the one computer to another and it still work?    I figured there would have been some footprint on the .sol file (I thought that’s what all those additional characters were in the .sol file when I opened it in WordPad to look at it were) from my flash player, some unique id or something that lets the .sol file only work with my flash player on my machine and not all flash players...but I guess not...any thoughts?   robert l. brueckmann vice president merlin securities 595 madison avenue new york, ny 10022 p: 212.822.4821 f: 212.822.4820     This message contains information from Merlin Securities, LLC, or from one of its affiliates, that may be confidential and privileged.
