I believe the limitation on trading on secret information is limited to 'privileged' information, not 'secret'. If you're entrusted with the information by the company (as an employee, officer, consultant, etc.), you are not allowed to use it. If you discover it for whatever reason, and have no actual relation to the company, I don't think it counts - that's how Mark Cuban gets by with Share Sleuth. That said, IANAL, so don't take that as legal advice :)
