Abstract
A device is provided for use with a database having stored therein, a plurality of signatures corresponding to a plurality of fields, respectively, wherein the plurality of fields correspond to a plurality of locations, respectively. The device includes an accessing component, a field-detecting component, a comparing component and an identifying component. The accessing component can access one of the plurality of signatures from the database. The field-detecting component can detect a first field based on a first location and can generate a detected field signature based on the detected first field. The comparing component can generate a comparison signal based on a comparison of the detected field signature and one of the plurality of signatures. The identifying component can identify the first location based on the comparison signal.
