摘要 Visual cryptography is an effective means for ownership protection of multimedia contents. Due to the massive amount of multimedia contents, compression is an inevitable part before transmission over channels. Recently, compressed sensing has attracted much attention with its superior performance in data compression. With compressed sensing, few amounts of coefficients are able to obtain reconstructed image with acceptable quality. In order to protect the ownership of multimedia contents with compressed sensing, we hide visual cryptography information, or shares, into compressed sensing coefficients. Besides, considering the characteristics of visual cryptography, compressed sensing coefficients are split into chunks for delivering over multiple channels. After reception, extracted shares can be verified to protect the ownership. Simulation results have pointed out that our method can be applicable, and integration with robust visual cryptography may lead to enhanced performances.
