    Abstract: Methods and apparatus for processing title data watermarked with a code. At least a portion of the title data may be watermarked at a plurality of locations within the title data with customer information data, so that the title data provided to a customer includes the watermark information. To obtain the code from the watermarked title data, watermarking information associated with the watermarked title data is first received. The watermarking information identifies a plurality of locations and a number to frequency modulation relationship at each of the locations. A different modulation scheme may be used at each location. The watermarked title data is demodulated at each of the plurality of placement locations based on the number to frequency modulation relationship. The code is then generated from the demodulated watermarked title data. A verification indication is output based in part on the generated code.
