Weighted visual secret sharing for general access structures based on random grids

作者：

Highlights：

• A weighted visual secret sharing scheme with no pixel expansion is proposed.

• The proposed scheme has both OR decryption and XOR decryption methods.

• The proposed scheme is suitable for general access structures.

• All shares can recover a lossless secret image.
