We show how a signatory can indicate coercion by embedding a secret message into the signature. Our scheme is practical and applies to standard signature schemes unlike the recent construction of Durnoga et al. (2013). The construction follows directly from kleptographic techniques due to Moti Yung and Adam Young.
