T he ubiquitous availability of image sensors in smartphones and other mobile computing devices makes feasible new applications for both barcodes that encode data as image patterns and watermarks that hide data in images. To support these new applications, a number of new methods have been developed for these long-standing image-based data communi cation interfaces, methods that are better suited for use with the image sensors. In this paper, we review these developments and the applications
