Articles, reviews etc about protection methods

[Alex Rashevsky]

Hi!
I'm searching for the articles, reviews, researches about copyright protection in the J2ME world. I read DRM articles and standards already. Comparison of the different methods will be the best. Book references are perfect too! Thanks for help.
PS: I found some articles in the internet, but there are not complete enough.
Does anybody know master or PhD theses about this topic? It can be very helpful for me.

I'm searching not for DRM review but for comparison different protection methods (I know that DRM is most useful).
But anyway thanks for the link. I didn't know about Google Scholar resource.
