The quick response codes (QR codes) are commonly seen in our daily lives. They are mainly composed of black or white square blocks, containing the URL or other form of information. We may compose several QR codes together by using interlacing for layered QR codes. With the concept of visual secret sharing (VSS), we may separate the interlaced QR code into several shares, and once received shares is more than the threshold, decoding for layered QR codes can be performed. Even the separated QR codes are not 100% recoverable, they can still be scanned and the information therein can be extracted. Our experiments have presented the applicability of the composition of two QR codes with the concept of visual secret sharing in the proposed method.
