Abstract

Systems and methods for controlling accuracy of transmitted information are described. A package is assembled based on a numerical value, such as a measurement, and one or more policies associated with the sender. When the package is received by a receiver, it is unpacked to yield a second value representing the numerical value and having a reduced accuracy with respect to the first value. The accuracy reduction depends on policies associated with the receiver and/or the sender. Examples of numerical values in different applications include geo-location data, medical data, and financial data.

Claims

1-42. -42. (canceled)

43. A method for controlling accuracy of location data comprising:

receiving, from a geo-location unit of a device, location data associated with a location;

transforming the location data, based on a specified resolution, into resolution-filtered location data;

packaging the resolution-filtered location data with a first policy articulating one or more rules associated with a use of the resolution-filtered location data; and

transmitting the packaged resolution-filtered location data and the first policy to a system associated with a consumer.

44. The method of claim 43, wherein the location data comprises latitude and longitude information associated with the location.

45. The method of claim 43, wherein the location data comprises a user-specified location.

46. The method of claim 43, wherein the location data compresses a physical address.

47. The method of claim 43, wherein the location data comprises at least one time indication associated with a generation of the location data by the geo-location unit.

48. The method of claim 43, wherein transforming the location data comprises randomizing the location data to generate the resolution-filtered location data.

49. The method of claim 43, wherein transforming the location data comprises transforming the location data according to one or more second policies.

50. The method of claim 49, wherein the one or more second policies articulate a distribution for the resolution-filtered location data.

51. The method of claim 49, wherein at least one of the one or more second policies is associated with the consumer.

52. The method of claim 49, wherein at least one of the one or more second policies is associated with a user of the device.

53. A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method comprising:

receiving, from a geo-location unit of a device, location data associated with a location;

transforming the location data, based on a specified resolution, into resolution-filtered location data;

packaging the resolution-filtered location data with a first policy articulating one or more rules associated with a use of the resolution-filtered location data; and

transmitting the packaged resolution-filtered location data and the first policy to a system associated with a consumer.

54. The non-transitory computer-readable medium of claim 53, wherein the location data comprises latitude and longitude information associated with the location.

55. The non-transitory computer-readable medium of claim 53, wherein the location data comprises a user-specified location.

56. The non-transitory computer-readable medium of claim 53, wherein the location data compresses a physical address.

57. The non-transitory computer-readable medium of claim 53, wherein the location data comprises at least one time indication associated with a generation of the location data by the geo-location unit.

58. The non-transitory computer-readable medium of claim 53, wherein transforming the measurement data comprises randomizing the measurement data to generate the resolution-filtered location data.

59. The non-transitory computer-readable medium of claim 53, wherein transforming the measurement data comprises transforming the measurement data according to one or more second policies.

60. The non-transitory computer-readable medium of claim 59, wherein the one or more second policies articulate a distribution for the resolution-filtered location data.

61. The non-transitory computer-readable medium of claim 59, wherein at least one of the one or more second policies is associated with the consumer.

62. The non-transitory computer-readable medium of claim 59, wherein at least one of the one or more second policies is associated with a user of the device.
