Methods and systems useful in linking from objects to remote resources
An identifier corresponding to an object is used in establishing links to related electronic resources. The identifier can be obtained by decoding a watermark, performing a hashing algorithm on content data, reading a bar code, etc. The object can be physical (e.g., a magazine page) or electronic (e.g., music or image data). Suitable devices useful with this technology include cell phones, PDAs, and the like, which may include sensors for capturing object data. The associated electronic resource can be a web site from which information, image/audio content, etc., is provided. A variety of other features and arrangements are also detailed.
1. A method comprising:
capturing image data from an object using an optical sensor device, wherein the object is free of evident data encoding;
after the capturing, providing image information corresponding to visual attributes of the image data to a processor, and receiving from the processor identification information corresponding to the image information, wherein the identification information has been derived by the processor through application of a processing algorithm to the image information;
searching a database by reference to the identification information;
presenting information on a display of a wireless device, wherein the presented information is related to information obtained from the database in response to the searching; and
transmitting first information from the wireless device to a first computer to authenticate the wireless device, or a user thereof.
2. The method of claim 1 , wherein the authenticating comprises authenticating the wireless device.
3. The method of claim 1 , wherein the authenticating comprises authenticating the user.
4. The method of claim 1 , wherein the wireless device comprises the processor.
5. The method of claim 1 , wherein the presented information is identified by reference to information obtained from the database in response to the searching.
6. A non-transitory computer-readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
capturing image data from an object, wherein the object is free of evident data encoding;
determining, after the capturing, identification information corresponding to image information corresponding to visual attributes of the image data, wherein the identification information is derived using a processing algorithm to the image information;
searching a database by reference to the identification information;
displaying information, wherein the displayed information is related to information obtained from the database in response to the searching; and
authenticating a wireless device, or a user thereof, wherein the authenticating comprises transmitting first information from the wireless device to a first computer.
7. The non-transitory computer-readable medium of claim 6 , wherein the authenticating comprises authenticating the wireless device.
8. The non-transitory computer-readable medium of claim 6 , wherein the authenticating comprises authenticating the user.
9. The non-transitory computer-readable medium of claim 6 , wherein the presented information is identified by reference to information obtained from the database in response to the searching.
10. An apparatus comprising:
an optical sensor configured to capture image data from an object, wherein the object is free of evident data encoding;
a processor configured to:
determine identification information corresponding to image information corresponding to visual attributes of the captured image data, wherein the identification information is derived using a processing algorithm to the image information; and
authenticating a wireless device, or a user thereof, wherein the authenticating comprises transmitting first information from the wireless device to a first computer;
search a database by reference to the identification information; and
a display configured to display information, wherein the displayed information is related to information obtained from the database in response to the searching.
11. The apparatus of claim 10 , wherein the authenticating comprises aunthenticating the wireless device.
12. The apparatus of claim 10 , wherein the authenticating comprises authenticating the user.
13. The apparatus of claim 10 , wherein the presented information is identified by reference to information obtained from the database in response to the searching.
