Abstract
Address information is steganographically encoded into audio or graphic data, and thereafter decoded to permit linking to the internet. The address information can be a literal URL, or may be an index to a database from which a corresponding URL can be obtained.
Claims46
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.
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.
A method of initiating access to a computer via a data communications medium, the method comprising:
- 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.
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.
A method comprising:
- at a first device, receiving data representing a graphic, the graphic having non-uniformly toned regions with information steganographically encoded therein;
- decoding the steganographically encoded information from the received data;
- communicating with a second, remote device;
- receiving data from the remote device;
- and
- controlling an aspect of operation of the first device in accordance with said data received from the remote device;
- wherein the data received from the remote device is a function of information decoded from the received data.
A method comprising:
- receiving graphic data;
- and
- steganographically encoding machine readable data in the graphic 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.
A tangible medium comprising an encoded graphic, the graphic comprising non-uniformly toned regions that are steganographically encoded to convey machine readable data, wherein said machine-readable data serves to elicit a processing action corresponding thereto when decoded by a first computer device.
A method comprising:
- receiving an index number;
- by reference to said index number, obtaining from a database an identification of a node on a computer network corresponding thereto;
- establishing a link to said identified node;
- receiving information from said node;
- and
- controlling operation of a user device in accordance with information received from said node;
- wherein the index number is based on information decoded from a steganographically encoded creative data object.
A network-connected device characterized by a decoder that decodes information steganographically encoded within a creative data object, the device utilizing said decoded information to elicit an action by a remote computer, said remote computer transferring information to said device through the network in accordance with information decoded from the creative data object.
A method for enabling graphic-based linking to the internet, comprising:
- receiving digital data corresponding to a commercial, or transaction-based, graphic image;
- steganographically encoding the graphic image to hide plural bit address information therein;
- and
- distributing the encoded graphic image data to users in digital, rather than hardcopy form;
- decoding the plural-bit address information from data corresponding to the encoded commercial, or transaction-based, graphic image;
- and
- directing a web browser to an internet address determined by reference to said decoded information;
- and
- from said internet address, presenting a user an opportunity to engage in a purchase transaction over the internet.
A method comprising:
- providing digital data at a user's computer, the data comprising plural-bit sampled values representing media content;
- passing said digital data to a processing system;
- receiving from said processing system an identifier derived from said sampled values;
- using said derived identifier to index a database;
- obtaining from said database a URL address corresponding to said derived identifier;
- establishing a link to said URL address;
- and
- presenting information to the user accordance with information obtained from said URL address.
