Barcodes For Mobile Phones
Abstract
2D barcodes were designed to carry significantly more data than its 1D counterpart. These codes are often used in industrial information tagging where high data capacity, mobility and data robustness are required. Mobile phones have evolved from just a voice communication device to what is now a mobile multimedia computing platform. Greater integration of multiple communication technologies into a single device has sparked some interesting applications of 2D barcodes in mobile phones.
Digital Watermarking is a technique used to label digital media by hiding copyright or other information into the underlying data. Embedding of digital watermarks is performed using 2D barcode in wavelet domain. The 2D barcode is insensitive to noise and has embedded error correction facility.
