A systematic solution based on the design of a heterogeneous code is proposed to promote the unified governance foundation of the existing Internet of Things (IoT). The proposed scheme enables advanced functionalities and maintains the compatibility with applications of the existing identifications (QR code) of things in IoT. The heterogeneous QR code is generated by invoking digital watermarking technique which embed a so called IoT standards code to the QR code. The result has shown that the heterogeneous QR code is backward compatible which implies that the embedding of the standards code does not introduce any reading difficulties to the original QR code. Moreover, a preprocessing scheme based on digital modulation is proposed for the standards code. The result has shown that the preprocessing is capable of enhancing the bit loading capability for standards code when given a fixed length of watermark for the sake of maintaining an acceptable performance.
