Android Blackmart Protection

What is exactly blackmart ? It seem's that it is an alternative market store for Android where you can install paid Application for free.

How can I protect my application against Blackmart ?


  1. Use Market Specific Licencing Criteria to make sure the user bought your app. If its not licenced, then you can remove it. Android Licencing Library
  2. Construct your own authentication process where you can assign each user his/her own id's and validate them against your server. This requires registration first. Ref:
  3. Use Open-id's such as Google/Facebook/Twitter if you are okay with third-party logins.
