In this article, an efficient verifiable sharing scheme is proposed that can satisfy significant essentials of distribution sharing and can achieve a iossless property of host media. Verifiability allows holders to detect and identify counterfeited shadows during cooperation in order to prevent cheaters. Only authorized holders can reveal the lossless shared content and then reconstruct the original host image. Shared media capacity is adjustable and proportional to the increase of the number of the distributed holders t. The more distributed holders, the larger the shared media capacity is. Moreover, the ability to reconstruct the image preserves the fidelity of valuable host media, such as military and medical images. According to the results, the proposed approach can achieve superior performance to that of related sharing schemes for effectively providing distributed media management and storage.展开更多
