Abstract EN
In secret image sharing schemes, the threshold may have to be adjusted in case of changes in the security policy and the adversary structure before recovering the secret image.
For example, if participants leave the group, their stego images are useless to them and may not be kept safely.
As a result, these images can be easily stolen and utilized by intruders, which reduces the security of the scheme.
To solve this problem, we propose a novel threshold changeable secret image sharing scheme with N potential changeable thresholds t 1 , t 2 , … , t N .
By preparing advance shares for thresholds t 1 , t 2 , … , t N and using the two-variable one-way function to generate the identification value, we can change the threshold when necessary.
The experiments show that the quality of the stego images in our scheme is satisfactory and the secret image can be recovered without distortion.
Moreover, the security analysis shows that we can change the threshold safely.
