REDUCED RESOLUTION LOCATION DETERMINATION FOR IMPROVED ANONYMITY OF USER LOCATION |
| 摘要 |
Reduced resolution location determination for improved anonymity of a user location is disclosed. In some implementations, a first location of a computing device operating in a geographic area is determined. A population density of the geographic area is estimated. A grid overlay is generated, including a number of cells based on the estimated population density. Using the grid overlay, a second location is generated for the computing device that is less precise than the first location. The less precise second location can be used in a local search or other application to improve the anonymity of the user location. |

1. A method comprising:
determining a first location of a computing device operating in a geographic area; estimating a population density of a geographic area; generating a grid overlay for the geographic area including a number of cells based on the estimated population density; and generating, using the grid overlay, a second location for the computing device that is less precise than the first location, where the method is performed by at least one hardware processor. |
