Why? Just look for a pattern of abnormal returns. (Hint: the SEC does this.) It's much easier to check for insider information after the fact than it is to profitably trade on it.

Does it work? (Hint: no)

This is only true for the least sophisticated insider traders.
Good enforcement is impossible without subjecting anybody trading stocks and everybody they know to a completely unprecedented level of surveillance. This would have to go far beyond the wildest Snowden revelations.
Perhaps not completely impossible in theory, but absolutely infeasible in practice. Building such a system would also be likely to result in far greater chilling effects on the markets than insider trading ever could.
