Handheld devices and methods for extracting data
First Claim
1. A handheld device comprising:
- an input configured to receive a subset of database information;
a memory configured to store the received subset of database information;
an optical imaging device configured to capture a portion of a map, wherein the portion of the map includes at least one steganographic watermark hidden therein through alterations to data representing the portion, wherein the alterations are generally imperceptible to a human observer of the portion of the map, and wherein the steganographic watermark includes map location information; and
a processor configured to;
determine which information of the retrieved subset of the database information corresponds to the map location information; and
control providing corresponding retrieved subset database information.

Abstract
The present invention relates generally to handheld devices and using such to extract identifying data. One claim recites a handheld wireless device including: an input for receiving a subset of database information; electronic memory for storing the retrieved subset of database information, the handheld device including an input device; an optical imaging device for capturing a portion of a map, the portion of the map including at least one steganographic watermark hidden therein through alterations to data representing the portion, the alterations being generally imperceptible to a human observer of the portion of the map, the steganographic watermark including map location information; an electronic processor configured to: determine which information of the retrieved subset of the database information corresponds to the map location information; and control providing corresponding retrieved subset database information. Other claims and combinations are provided as well.
