    $ Ubuntu Software Center's paid application's security. Is there any?

    Sorry, I'm having trouble finding this information:

    I want to know if developers have any anti piracy security for purchased applications, which are done through 10.10's Ubuntu Software Center "For Purchase" section. In other words, once the purchased application is on someone's computer are there any deterrents in place to keep the user from freely redistributing the application?

    Thank you very much!

    I recall Canonical announcing that the app store will have functionality for managing reinstallations when transferring purchased apps from one system to another.

    I have seen nothing about client-side DRM, and I doubt that's coming to an open platform.

    Preventing the transfer of paid software from one computer to another in violation of the license will require application logic making calls to an activation server. While the app store channel can prevent over-installation by registered accounts, there is no way it can prevent someone from accessing the binaries directly and transferring them to another machine without having some sort of kernel-level DRM.

    It's a moot point, really. There has yet to be any application or scheme which has proven resistant to the best efforts of the top level warez crews. If people want to pirate the application, then it will be pirated. The best defense against that is adding value through regular updates (be sure to update the binary), good support, and paid subscriber services.

    The best you can hope to do is prevent casual copying by limiting activated installations through app logic, and discouraging license sharing by using a key tied to a person's identity (name, email, etc).

    If you do implement some sort of key, you'll want to use asymmetric cryptography to ensure that no key generators can be built by reverse engineering the application. That forces the warez crews to re-crack each binary release.

    Honestly, the best thing you can do is prevent casual copying through application logic, and encourage sales by providing some sort of service which can't be infinitely copied by anyone with a BT client or Rapidshare account.

    Currently there's no DRM-like application security system. Developers have to rely on the good will of the users to appreciate the fact that there's no DRM and show that they're responsible enough to not need any DRM.

    Personally, I'd rather have platform-wide standardized DRM managed by Canonical than every developer get paranoid and implement some DIY anti-copy method themselves. This model reminds me an awful lot of the iOS jailbroken community's "app store", and the things that developers do to ensure their paid apps aren't copied are crazy and border on privacy invasion.

    Amazon's MP3 store has no DRM, and I think it does just fine. I know I buy almost all my music from Amazon MP3. I don't think even iTunes as DRM any more.

    I realize that's music and not applications, but piracy is for everything.

    Of course not, but having some level of built-in default deterrent, which sounds like a great idea, will be an added incentive to providers.

    And it would mean less development and resources required by the app developer to protect the product.

    Oh well.. 11.04 maybe...

    As jdong said, there is currently no DRM system in place in the USC. It is definitely something Canonical is looking at, as I recall it being mentioned before, but it is not currently on the Ubuntu Software Center roadmap.

    Personally, I think it's a waste of time. All DRM methods are eventually broken, even methods engineered by huge corporations such as Sony and Microsoft, this won't be any different.

    I know they're going to do it anyway, because it will attract more developers, but it will really just be for show.

    Correct, which works fine if you plan on selling at a high volume at a low price, but protection would be better at low volume high-priced sales, which would be nice to see come to Ubuntu.

    Why? All of the popular music available from Amazon is already available from various sources for free(Neatly packaged by album and/or artist), and so will all of the popular applications from the USC, DRM or not.

    I would feel better about buying stuff from the USC without DRM.

    If you're planning to sell your software to Ubuntu Linux users at a high price... good luck with that, unless it's a native (non-Wine) Adobe Creative Suite.

    Why do you say that? If it's a quality application which cannot be matched by free software, I think the people who need it will buy it.

    Do you have any reason to think they won't?
