Software developer Oleh Yuschukhas developed a Windows application that can turn any ordinary A4 piece of paper into a hard drive. Using a high-resolution printer, PaperBack allows users to store up to half a megabyte of data per side of paper. The program turns data in a bitmap of data matrices, where each data matrix can store 80 bytes of data.
The matrices used in PaperBack resemble QR codes, and can be read using any scanner with the TWAIN interface along with the free application. The software also comes with a built-in compression that’s optimized for text files, and the original file could still be restored even if 20 per cent of the paper has been destroyed.
