Sentence examples for a secret image from inspiring English sources

Numerous visual cryptography schemes (VCSs) have been proposed to protect a secret image with share images.

A (t,n) visual cryptography scheme (VCS) encodes a secret image into n shadow images (shadows) distributed among n participants.

Then, the feature and watermark are used to generate a secret image by the codebook of visual cryptography technique.

Thien and Lin [8] proposed the (t, n) threshold method, which distributes a secret image among n shares.

Watermarking is the process of embedding a secret image into a host image without degrading the imperceptibility of the observer.

Block-based progressive visual secret sharing (BPVSS) is an encryption technique that utilizes the human visual system to recover a secret image.

In this paper, a novel secret image sharing scheme is proposed to encode a secret binary image into meaningful shadow images.

Conventional visual secret sharing schemes are designed for a single secret image so it is inefficient to generate numerous share images for multiple secret images simultaneously.

Wang and Shyu [4] proposed a scalable secret image sharing scheme.

In this paper, we propose a scalable secret image sharing (SSIS) method that provides gradual reconstruction with smooth scalability.

Most VCSs use random-looking shares to code a single binary secret image.
