Abstract
Following the development of a method by Blakley in 1979 to share secret data among participants, in 2008, Tso extended that method to transmit information while reducing the storage space and bandwidth by quantizing the secret image. Owing to its use of quantization to generate shares, the method of Tso fails to obtain a reconstructed image distortion free. In 2010, Ulutas et al. proposed a solution to obtain the reconstructed image entirely. However, their method incurs the share expansion prob-lem. Therefore, this work presents a novel method that combines the methods of Tso and Ulutas et al. to transmit a secret image with small shares and obtains the reconstructed image distortion free. The proposed scheme also provides the progressive data transmission feature.
