Method for managing privacy of digital images
A captured digital image is stored in memory together with metadata derived from a location signal only if the location metadata is determined not to be within one or more predefined exclusion zones. A GPS receiver module can be implemented to obtain the location signal.
1. A method for displaying digital images having location metadata, comprising:
storing, in one of at least one digital memory of a processor-based photo management unit, a digital image file associated with a first user;
storing, in any of the at least one digital memory of the processor-based photo management unit, geographic location metadata for the digital image file;
storing, in the processor-based photo management unit, one or more geographic exclusion zones associated with the first user;
automatically determining, by the processor-based photo management unit, whether a geographic location of the geographic location metadata of the digital file is within any of the one or more geographic exclusion zones by loading the one or more geographic exclusion zones and comparing the geographic location metadata for the digital image file to each of said one or more geographic exclusion zones; and
if the geographic location is within any of the one or more geographic exclusion zones, transmitting, by the processor-based photo management unit, digital image data of the digital image files to a computer associated with a second user, otherwise
if the geographic location is not within any of the one or more geographic exclusion zones, transmitting, by the processor-based photo management unit, digital image data of the digital image files and the geographic location metadata to the computer associated with the second user.
2. The method of claim 1 , further comprising receiving, by the processor, a user-defined geographic exclusion zone.
3. The method of claim 1 , wherein determining that the geographic location metadata of the digital image file is within the geographic exclusion zone comprises determining that the geographic location metadata of the digital image file defines a location that is within an area defined by the geographic exclusion zone.
4. The method of claim 1 , further comprising:
defining a region on a digital display of a geographic map; and
storing the defined region as one of the geographic exclusion zones associated with the first user.
5. The method of claim 1 , further comprising, if the geographic location is within any of the one or more geographic exclusion zones, removing, by the processor, the geographic location metadata from the digital image file.
6. The method of claim 1 , wherein the at least one geographic exclusion zone has a circular shape.
7. The method of claim 6 , wherein determining that the geographic location metadata of the digital image file is within the geographic exclusion zone comprises calculating a great arc distance using a Haversine formula.
8. The method of claim 1 , wherein the at least one geographic exclusion zone has a polygonal shape.
9. The method of claim 8 , wherein determining that the geographic location metadata of the digital image file is within the geographic exclusion zone comprises calculating a line starting from the geographic location metadata and determining how many sides of the at least one geographic exclusion zone are crossed using a Jordan curve theorem.
10. The method of claim 1 , wherein the at least one geographic exclusion zone has a rectangular shape, and further wherein the determining that the geographic location metadata of the digital image file is within the geographic exclusion zone comprises:
determining whether a longitude of the geographic location metadata of the digital file is between a longitude of a first coordinate and a second coordinate of the geographic exclusion zone, wherein:
the first coordinate and the second coordinate are both different corners of the at least one geographic exclusion zone,
the first coordinate is at a corner of two sides of the at least one geographic exclusion zone where the two sides intersect with each other, and
the two sides do not intersect with the second coordinate; and
determining whether a latitude of the geographic location metadata of the digital file is between a latitude of the first coordinate and the second coordinate of the geographic exclusion zone.
11. A method for transmitting digital images with location metadata between a plurality of users including:
providing a database having a plurality of users;
receiving, by a processor-based photo management unit, a digital image file from a first user;
receiving, by the processor-based photo management unit, geographic location metadata for the digital image file;
receiving, by the processor-based photo management unit, one or more geographic exclusion zones associated with the first user;
automatically determining, by the processor-based photo management unit, whether a geographic location of the geographic location metadata of the digital file is within any of the one or more geographic exclusion zones by loading the one or more geographic exclusion zones and comparing the geographic location metadata for the digital image file to each of said one or more geographic exclusion zones; and
if the geographic location is within any of the one or more geographic exclusion zones, transmitting, by the processor-based photo management unit, digital image data of the digital image file to a second user, otherwise
if the geographic location is not within any of the one or more geographic exclusion zones, transmitting, by the processor-based photo management unit, digital image data of the digital image file and the geographic location metadata for the digital file to the second user.
12. The method of claim 11 , further including causing the digital image to be displayed on a digital electronic display device.
13. The method of claim 12 , further including causing transmitted geographic location metadata for the digital image file to be displayed on the digital electronic display device.
14. The method of claim 11 , further including storing at least a portion of the transmitted digital image data on a digital memory device.
15. The method of claim 14 , further including storing at least a portion of any transmitted geographic location metadata of the digital image file on the digital memory device.
16. The method of claim 11 , further comprising receiving, by the processor, a user defined geographic exclusion zone.
17. The method of claim 11 , wherein determining that the geographic location metadata of the digital image file is within the geographic exclusion zone comprises determining that the geographic location metadata of the digital image file defines a location that is within an area defined by the geographic exclusion zone.
18. The method of claim 11 , further comprising, if the geographic location is within any of the one or more geographic exclusion zones, removing, by the processor, the geographic location metadata from the digital image file.
19. The method of claim 11 , wherein the at least one geographic exclusion zone has a circular shape.
20. The method of claim 11 , wherein the at least one geographic exclusion zone has a polygonal shape.
