*Both S1 and S2 were introduced by embedding data bits into H via the minimum-preserved scheme (A). +S1 was introduced by embedding a secret message into H via the minimum-preserved scheme, and S2 was introduced by the BV embedding scheme (B). †Both S1 and S2 were introduced by embedding data bits into H via the minimum-preserved with squeezing scheme (C). |
