In recent years there has been increasing attention towards digital rights. Therefore, this paper proposes a matrix barcode to verify image copyrights. The copyright text, Quick Response code (QR code), and watermarking techniques are used to achieve a hidden identification scheme implementing direct sequence spread spectrum (DSSS) and modulation of the modified code division multiple access (MCDMA) to hide the QR code data. DSSS and MCDMA hash the data and QR code has a robust feature to prevent external attacks and destruction of the cover image. The QR codes information can be easily extracted by mobile devices. Even if the barcode suffers external damage, a copy of the barcode can be hidden within the image to easily recover the barcode data. Compare to the other scheme, our method has two advantages: 1) the QR code has universal, rapid identification and fault tolerance features, so it is suitable for copyright protection; and 2) using DSSS and MCDMA methods to hide information can provide more security and fault-tolerant features.
