One claim recites a method of accessing content stored in a remote database. The method includes: receiving video or audio data; decoding an auxiliary machine-readable code from the video or audio data; deriving a fingerprint, which fingerprint is separate from the machine-readable code, from the video or audio data itself; providing user characteristics or an index to user characteristics; and by using the machine-readable code, fingerprint and user characteristics or information obtained with the index to user characteristics, accessing the content stored in the remote database. Of course, additional combinations and claims are provided as well. ## Claims ### Claim 1 A system comprising: a sensor configured to acquire electronic data corresponding to audio or an image, wherein the audio or image comprises a steganographic watermark embedded therein; a processor programmed with instructions configured to read the embedded steganographic watermark from the electronic data; a memory having a unique identifier that uniquely identifies a browser; and wherein the processor is further programmed with instructions configured to: communicate with a network resource, wherein the communication comprises a resource locator contained within the watermark and the unique identifier, wherein the network resource identifies a network location based at least in part on the resource locator and user characteristics, wherein the user characteristics are associated with the unique identifier, and wherein the user characteristics comprise user history; receive communication instructions from the network resource comprising the network location; and access remotely located content on the network resource. ### Claim 2 (depends on 1) The system of claim 1, wherein the user characteristics comprise preferences. ### Claim 3 (depends on 1) The system of claim 1, wherein the user characteristics comprise at least access rights. ### Claim 4 (depends on 1) The system of claim 1, wherein communication with the network resource is done wirelessly. ### Claim 5 (depends on 1) The system of claim 1, wherein the processor is further programmed with instructions configured to provide a web browser. ### Claim 6 (depends on 1) The system of claim 1, wherein the image comprises a photograph. ### Claim 7 (depends on 1) The system of claim 1, wherein the steganographic watermark comprises digital watermarking. ### Claim 8 A method comprising: acquiring electronic data corresponding to audio or an image, wherein the audio or image comprises a steganographic watermark embedded therein; communicating with a network resource, wherein the communication comprises a resource locator contained within the watermark and a unique identifier that uniquely identifies a browser, wherein the network resource identifies a network location based at least in part on the resource locator and user characteristics, wherein the user characteristics are associated with the unique identifier, wherein the user characteristics comprise user history; receiving communication instructions from the network resource comprising the network location; and accessing remotely located content on the network resource. ### Claim 9 (depends on 8) The method of claim 8, wherein the user characteristics comprise preferences. ### Claim 10 (depends on 8) The method of claim 8, wherein the user characteristics comprise at least access rights. ### Claim 11 (depends on 8) The method of claim 8, wherein communication with the network resource is done wirelessly. ### Claim 12 (depends on 8) The method of claim 8, further comprising providing a web browser. ### Claim 13 (depends on 8) The method of claim 8, wherein the image comprises a photograph. ### Claim 14 (depends on 8) The method of claim 8, wherein the steganographic watermark comprises digital watermarking. ### Claim 15 A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising: instructions to acquire electronic data corresponding to audio or an image, wherein the audio or image comprises a steganographic watermark embedded therein; instructions to communicate with a network resource, wherein the communication comprises a resource locator contained within the watermark and a unique identifier the uniquely identifies a browser, wherein the network resource identities a network location based at least in part on the resource locator and user characteristics, wherein the user characteristics are associated with a unique identifier, and wherein the user characteristics comprise user history; instructions to receive communication instructions from the network resource comprising the network location; and instructions to access remotely located content on the network resource. ### Claim 16 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the user characteristics comprise preferences. ### Claim 17 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the user characteristics comprise at least access rights. ### Claim 18 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein communication with the network resource is done wirelessly. ### Claim 19 (depends on 15) The non-transitory computer-readable medium of claim 15, further comprising instructions to provide a web browser. ### Claim 20 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the image comprises a photograph.
