ABSTRACT:
This invention provides for a method of mapping data to data region dots on a photograph. The method includes the steps of compressing the data with a JPEG compression technique, and redundantly encoding the compressed data using Reed-Solomon encoding techniques. The method also includes the steps of shuffling the encoded data in a deterministic manner to reduce potential effects of localized encoded data damage to said photograph, and printing the shuffled data as dots in data blocks on the photograph.
