Abstract
A method of storing data on a photograph includes delimiting a plurality of data block regions on the photograph, the plurality of data block regions superposing a region of the photograph delimited for the printing of a photographic image; compressing data representing the image contained in the photograph with a compression technique; redundantly encoding the compressed data using Reed-Solomon encoding techniques; shuffling the redundantly encoded compressed data in a deterministic manner to reduce potential effects of localized encoded data caused by damage to the photograph; and printing the shuffled data as dots within the data block regions on the photograph. Each of the plurality of data blocks is printed on a first side with a first column of orientation dots, and on a second side with a second column of orientation dots.
