Secret image sharing, as an extension of secret sharing, has attracted the attention of many scholars in recent years. Multi-secret image sharing is an extension of traditional secret image sharing in which only one secret image can be shared among one group. In order to extend the utility of the mechanism, we propose an innovative (n, n) secret image sharing scheme based on matrix transformation. Due to the skillful design of the matrix operation used in matrix transformation, the proposed scheme is applicable to more than one secret image. Further, more secret images and participants can be included in this sharing system even after the secret image sharing procedure has been constructed. Also, the proposed scheme produces high-quality shadow images, and it can reconstruct the secret images losslessly. Moreover, the computational complexity of the proposed scheme is minimized by only using the XOR operation, which stands for exclusive or and is a logical operation that outputs true whenever both inputs differ. The experimental results demonstrated that the proposed scheme provides the aforementioned advantages.
