Methods, apparatus and arrangements for device to device communication

A method employing a user's portable device, the device including a touch screen display, one or more processors and a sensor, the method including acts of:

• obtaining a payload corresponding to information;
• providing the payload to an erasure code generator, in which the erasure code generator produces a plurality of outputs;
• generating an image;
• embedding one of the plurality of outputs in a copy of the image and proceeding with embedding until each of the plurality of outputs is so embedded in a copy of the image, in which the embedding utilizes digital watermarking;
• causing the touch screen display to display embedded image copies so as to cause a static image display effect, the displayed embedded image copies being displayed by the portable device in response to a user input.

A method employing a first portable device, the first portable device including a touch screen display, one or more processors and an input, the method including acts of:

• obtaining a payload;
• using the one or more processors, processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of outputs corresponding to the payload;
• obtaining a plurality of graphics;
• using the one or more processors, embedding one of the plurality of outputs in one of the plurality of graphics and proceeding with embedding until each of the plurality of outputs is so embedded, respectively, in a graphic of the plurality of graphics, in which the embedding utilizes digital watermarking;
• causing the touch screen display to display embedded graphics of the plurality of graphics, so that a digital watermark reader analyzing captured image data representing the touch screen display can recover the payload, in which a smartphone comprises the digital watermark reader.

A portable apparatus comprising:

• a touch screen display;
• an input;
• memory comprising a payload;
• and
• one or more electronic processors configured for:
• processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of outputs corresponding to the payload;
• obtaining a plurality of graphics;
• embedding one of the plurality of outputs in one of the plurality of graphics and proceeding with embedding until each of the plurality of outputs is so embedded, respectively, in a graphic of the plurality of graphics, in which the embedding utilizes digital watermarking;
• and
• causing the touch screen display to display embedded graphics of the plurality of graphics, so that a digital watermark reader analyzing captured image data representing the touch screen display can recover the payload.
