Secure spread-spectrum data embedding with PN-sequence masking

作者：

Highlights：

• PN masked SS embedding can offer efficient security against current SS embedding analysis.

• Optimal carrier designs can further improve recovery performance.

• PN-masked multi-carrier/multi-message SS embedding is also studied.

• Experimental studies confirm the benefits of the PN-masked optimal SS embedding.
