US Patent 7967406 Method of storing data on a photograph

A method of storing data on a photograph containing an image includes the steps of: delimiting a plurality of data block regions on the photograph; 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 damage to the image of said photograph; and printing the shuffled data as dots within the data block regions on the photograph. The printing of the shuffled data is performed simultaneously with a printing out of the image of the photograph.
