Abstract

A method and apparatus for providing geographically authenticated electronic documents is disclosed. Authentication for attributes for an electronic document stored on a computer network are defined, the attributes comprise at least one attribute describing a geographic location associated with the electronic document. Authenticated attributes (e.g., geographic location) of electronic documents (e.g., Web pages) allow for more accurate geographic searching and filtering. An authenticated digital certificate is created and associated with an electronic document. The authenticated digital certificate can be stored within the electronic document, such as can be done with HTML tags on a Web page. The digital certificate can also be stored as a separate file associated with the electronic document, as a separate signed digital certificate and as a database record.

Claims

1. A computerized method of searching for electronic documents, the method comprising:

receiving a search query including a keyword and a geographic term;

responding to the search query by processing a parallel search including;

searching a searchable index of spidered website content; and

searching a database, independent of the searchable index search, for verified URL addresses associated with the geographic term, the database storing information about a plurality of online websites, including a URL address of a website and a verified geographic location associated with the website, the geographic location being verified using a mechanism other than the content of the website;

comparing the searchable index search results with the geographically verified search results;

determining, based on the comparison, which URL addresses in the searchable index search results match the geographically verified search results; and

providing the URL addresses in the searchable index query results that match URL addresses in the geographically verified search results.

2. A computerized method according to claim 1 wherein verifying the geographic location of the website using a mechanism other than the content of the website further includes:

determining a business associated with the website; and

authenticating the geographic location of the business using a Yellow Pages directory.

3. A computerized method according to claim 2 wherein the Yellow Pages directory does not identify the URL address of the business.

4. A computerized method according to claim 1 wherein verifying the geographic location of the website using a mechanism other than the content of the website further includes:

determining a business associated with the website; and

authenticating the geographic location of the business using a United States Postal Service street listing database.

5. A computerized method according to claim 1 wherein verifying the geographic location of the website using a mechanism other than the content of the website further includes:

determining a business associated with the website; and

authenticating the geographic location of the business using a credit card online merchant database.

6. A computerized method according to claim 1 wherein searching a searchable index of spidered websites further includes removing the geographic term from the search query and searching the searchable index using the keyword in the search query.

7. A computerized method according to claim 1 wherein searching the database of geographically verified URL addresses further includes:

enhancing a geographic boundary associated with the geographic term in the search query; and

using the enhanced geographic boundary to expand the search of the database of geographically verified URL addresses.

8. A computerized method according to claim 1 wherein providing the URL addresses in the searchable index query results that match the URL addresses in the geographically verified search results further includes presenting the matching results for display to a user.

9. A computerized method according to claim 8 wherein presenting the matching results for display to a user further includes identifying the matching results on the display using at least one of the following:

a particular color, highlighting, double underlining, italicizing, or graphic insertion for the matching results.

10. A computerized method according to claim 8 wherein the geographic term in the search query corresponds to a geographic region for a desired business specified by a user.

11. A computerized method according to claim 10 wherein presenting the matching results for display to a user further includes providing a warning to the user if a URL is selected that corresponds to a business, which is outside of the geographic region.

12. A computerized method according to claim 1 wherein the keyword and geographic term search query is initiated by a user who is searching for a local business that offers a particular product or service, where the keyword in the search query corresponds to the particular product or service, and where the geographic term in the search query corresponds to the physical location of the business.

13. A computerized method according to claim 1 wherein the matching results are displayed to a user in a geographic portal, where the interface for the portal includes one of the following:

a search engine interface, a directory service interface, or a map interface.

14. A computerized method according to claim 13 wherein the matching URL addresses are used to create the geographic portal with a localized index, where the localized index of the geographic portal is create by:

connecting, using a spider, to the URLs; and

downloading and indexing the websites associated with the URLS onto a local computer system.

15. A computerized method according to claim 1 wherein the URL addresses in the geographically verified search results are associated with business that are physically located within the geographical area specified.

16. A computerized method according to claim 15 wherein the searchable index search results are compared with the geographically verified search results to eliminate false positives that are outside of the geographical area specified.

17. A computerized method according to claim 1 wherein the response to the search query further includes:

using the keyword and the geographic term in the search query, searching a database storing geographic terms used for non-geographic purposes; and

if a match is found in the non-geographic terms database, determining that the search query is not a geographically related search.

18. A computerized method according to claim 1 wherein the search query is received by a web browser plug-in, where the web browser plug-in detects the keyword and the geographic term in the search query.

19. A computerized method of searching for electronic documents, the method comprising:

using a web browser plug-in detecting a search query having a keyword and a geographic term;

determining whether the search query relates to a geographic search by searching, using the keyword and geographic term, a database storing geographic terms used for non-geographic purposes;

if a match is not found in the non-geographic terms database, determining that the search query is a geographically related search;

responding to the geographically related search by processing a parallel search including;

searching a searchable index of spidered website content; and

searching a database, independent of the searchable index search, for verified URL addresses associated with the geographic term, the database storing information about a plurality of online websites, including a URL address of a website and a verified geographic location associated with the website, the geographic location being verified using a mechanism other than the content of the website;

comparing the searchable index search results with the geographically verified search results;

determining, based on the comparison, which URL addresses in the searchable index search results match the geographically verified search results; and

providing the URL addresses in the searchable index query results that match URL addresses in the geographically verified search results.
