    摘要: A novel secret sharing scheme for color images with small shadows and
    error-resilient capability was proposed that combines compressive sensing and Shamir’s
    (k, n)-threshold scheme. Since the human eye is more sensitive to the luminance of an
    image than its chromaticity, first, this scheme converts RGB images into YUV format
    and compresses the components of luminance and chrominance using a different measurement
    rate. Then, the measurement values are quantified and encoded as polynomial
    coefficients in Shamir sharing to get n shadow images. At the receiver side, the secret
    image can be reconstructed if any k of n shadows are offered, while less than k shadows
    reveal no information. The simulation results showed that the scheme had a small
    shadow size and also achieved good error-resilient capability. Even though the shadow
    images may be affected by noise or a hostile attack in the transmission process resulting
    in some distortion, the managers still are able to reconstruct the original secret image.
    Therefore, this scheme provides advantages over others in the actual transmission environment.
