摘要：

This paper proposes two techniques in enhancing the robustness of a joint image encryption and data insertion method against lossy compression [1]. Safety zone is first introduced to ensure that pixel values representing '0' are separated from those representing '1' with a gap in between. This empty gap serves as a buffer so that pixels from both groups do not cross and eventually affect the extraction process. Next, majority vote is also adopted so that error can be further suppressed, although reducing number of bits that can be inserted. Results suggest that both strategies can suppress error caused by lossy compression.
