Hierarchical secret image sharing scheme in compressed sensing

作者：

Highlights：

•

• A hierarchical secret image sharing (SIS) scheme with flexible shadow size.

• Compressed sensing on prediction error image and (k,n) polynomial scheme.

• Decoding needs presence of mandatory share (MS) and general shares (GSs).

• Decrease in measurements saves in bandwidth, improves security.

• Average quality of the decoded image is ∼32.6 dB, ∼46.1 dB at 20%, 60% measurements.
