Abstract

The disclosure relates to digital signal processing such as digital watermarking, and the utilization of portable devices for such signal processing. One claim recites a portable device comprising a touch screen display; memory for storing a payload, and for storing portions of imagery; means for processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of outputs corresponding to the payload; means for embedding a first of the plurality of outputs in a first portion of the imagery and proceeding with embedding until each of the plurality of outputs is embedded in portions of the imagery; and means for causing the touch screen display to display embedded portions of imagery so that a digital watermark reader analyzing captured image data representing the touch screen display can recover the payload. Of course, other claims and combinations are provided.
