Abstract
The data hiding technique based on halftone dot features (spatial position or shape) has a special anti-copy function. However, this function has a very strict demand for image acquisition and authenticity identification. We provide a high-resolution imaging control technology of the macro mode for iPhones based on Xcode tool and ZXing Jar. At the same time, an image resolution estimation algorithm is proposed based on the method of least squares.
