In recent years, three-dimensional space digital watermarking has become a new hotspot in optical information security. This paper presents a new three-dimensional space digital watermarking technology based on integrated imaging. Three-dimensional digital watermarking is generated by the computational integral imaging system that is implemented with the smart pseudoscopic-to-orthoscopic conversion model. The discrete wavelet transform al- gorithm is applied to embed and extract the three-dimensional digital watermarking. Three-dimensional digital watermarking is identified and shown by the integral imaging system. The feasibility and effectiveness of the proposed technology is demonstrated by experiment. The new technology is robust and secure; its image quality and display quality can also meet the criteria of the human visual model. The proposed technology opens up a new research perspective for the copyright protection of three-dimensional digital muhimedia products.
