“…The main operations of Chuang In the aspect of secret payload, the randomly embedding strategy of Lin's scheme results have too many error codewords in the QR code, the secret payload is dramatically reduced, it is in the range of [2,1215] bits. The QR code error correction capacity determines the secret payload of Chow et al's scheme and He et al's scheme, their payloads are in the range of [16,9620] bits. At the same time, beside the secret share, Huang et al's scheme also embedded many side information to implement the cheating preventions function and embedding key reconstruction.…”

“…The meaningful QR code pseudoshares reduce malevolent people's attentions with the help of the cheater detection function which makes it difficult to forge a fake QR code pseudo-shares. Chow et al [15] and He et al [16] proposed two QR code secret sharing scheme to improve the security of Chuang's scheme. Their schemes employed the symmetric encryption algorithm to encrypt shares before embedding shares into the meaningful cover QR codes.…”

Secret sharing is an effective way of protecting secret messages. However, the traditional secret sharing schemes are considered meaningless due to malicious people attention which might raise risks. To overcome the weakness, this paper presents an effective secret sharing scheme with the functionality of cheater identification, based on meaningful QR code. The secret message will be split and concealed in the padding region of cover QR codes with the assistance of Latin square and it can be completely restored when all the involved participants cooperate. The concealing strategy exploits the characteristic of Reed-Solomon (RS) code to ensure the strong robustness of generated QR code pseudo-shares. The meaningful QR code pseudo-shares help to reduce the curious of unrelated persons. Some experiments were done to evaluate the performance of proposed scheme. The results showed that the proposed scheme is feasible, efficient and secure compared to the other existing schemes. It also achieves a higher secret payload and maintains stronger robustness.
