1. Introduction Steganography conceals a secret message in cover media. A classic scenario illustrating linguistic steganography is the “Prisoner’s problem”. Consider that Alice and Bob were two inmates in a prison, planning to escape. To facilitate their plan, they decided to exchange secret messages via short notes. However, all message exchanges must be checked by Eve. If Eve successfully detects any concealed message, she retains the authority to terminate any further communication.

1. Introduction With the increasing maturity of cloud technology, more and more users prefer to upload data to the cloud for storage. However, if the uploaded data contain sensitive images or confidential information, precautions must be taken to prevent data breaches during transmission or storage in the cloud. Typically, encryption [1,2,3,4] or steganography [5,6,7,8,9,10] is employed to protect critical data before uploading.
