I like to create my own distro based on Ubuntu. I may modify the source of some packages. When I read intellectual-property-policy of Ubuntu, I noticed the following rule.

Any redistribution of modified versions of Ubuntu must be approved, certified or provided by Canonical if you are going to associate it with the Trademarks. Otherwise you must remove and replace the Trademarks and will need to recompile the source code to create your own binaries. This does not affect your rights under any open source licence applicable to any of the components of Ubuntu. If you need us to approve, certify or provide modified versions for redistribution you will require a licence agreement from Canonical, for which you may be required to pay. For further information, please contact us (as set out below).

Consider that I have recompiled the Ubuntu package source and built my own repository: I actually pull the source apt-get source, build deps apt-get build-dep and use dpkg-buildpackage to compile. Once .deb is generated, I host it in my local private apt-repository.

In the future, if I have to legally prove that I have indeed recompiled the Ubuntu package source, how can I prove it? Do I have to inject any custom tags in generated .deb or binary inside the .deb? I checked for the custom tags (just to find some leads) in MintLinux distro's .deb but I couldn't able to see any custom tags.

You need to remove all items that are trademarked and after doing that you have to recompile to make new binaries. Not recompiling is not an option so you do not need to prove you recompiled.

You could remove all trademarks except for 1 and recompile. That is still a violation and you did recompile. Canonical will tell you what trademarks are still there if there are still trademarked items in your version.

Oh and I am not a lawyer... so if you want an official answer that can be used as a legal argument you need to contact an actual copyright/trademark lawyer and/or Canonical directly :)
