Abstract

For digital communication, distributed storage and management of media content over system holders is a critical issue. In this article, an efficient verifiable sharing scheme is proposed that can satisfy the significant essentials of distribution sharing and can achieve the lossless property of the host media. Verifiability allows holders to detect and identify the 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. The shared media capacity is adjustable and proportional to the increase of t. The more distributed holders, the larger the shared media capacity. 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 in order to effectively provide distributed media management and storage.
