Abstract

An internet linking method includes providing plural-bit sampled values representing media content at a user'"'"'s computer. This digital data is passed to a processing system, and an identifier of the media content derived from the sampled values is returned from that system. This derived identifier is used to index a database, from which a corresponding URL address is obtained. A link can then be established to that URL address, and information obtained from that address can be presented to the user. A steganographic decoding technique can be used in the processing system to derive the media content identifier. A variety of other features and arrangements are also detailed.

Claims

1. A method for enabling audio-based linking to the internet, comprising:

steganographically encoding an audio signal with address information; and

distributing the encoded audio signal to users, who can decode the address information therefrom and use same in establishing a link to the internet.

2. The method of claim 1 in which the address information is not recognizable as such to human listeners of said audio signal.

3. The method of claim 1 in which the address information comprises a URL.

4. The method of claim 1 in which the address information comprises an index to a remote data structure, the remote data structure having a corresponding URL address stored therein.

5. The method of claim 1 in which the audio conveys said address information notwithstanding transformation into or out of digital form.

6. A computer readable storage medium having stored thereon audio encoded according to claim 1.

7. A method comprising:

receiving audio data; and

steganographically encoding machine readable data in the audio data, the machine readable data identifying a computer implemented process that is to be invoked when the steganographic encoding is decoded and acted upon by a computer device.

receiving artwork corresponding to an object to be printed, the artwork including text and background;

steganographically embedding into at least the background of said artwork certain information indicative of an address associated with said computer; and

printing said object using the artwork into which said information has been steganographically embedded.

9. A physical object printed on a substrate and including text and background, at least the background being of continuous tone and having a plural-bit code steganographically embedded therein, said code being an index to a data structure that specifies address information of a computer resource that is to be associated with said object.

10. The object of claim 9 wherein said data structure is maintained on a computer separate from the computer whose address information is to be associated with the object.
