Concealment is active, nondisclosure is passive.

Concealment involves taking affirmative steps to hide something; nondisclosure involves failing to take affirmative steps to reveal it.

The legal consequences of one may be different from those of the other depending on the circumstances. For example, someone accused of failing to disclose something may not have known whatever it was he is accused of not disclosing. The consequences of his failure may depend on whether he should have known it -- that is, whether his role in the transaction imposed a duty on him to inquire and make a reasonable effort to uncover it.
