Abstract
A method of associating auxiliary data with a digital ink stream comprises capturing a sequence of samples representing a digital ink stream and modifying the sample information, or inserting a plurality of new samples into the sample sequence, the modified or new samples representing auxiliary data. New samples are inserted in between existing samples and are essentially imperceptible to a person viewing the digital ink image, while an authorised recipient can extract the auxiliary data.
