## Abstract

The invention discloses a system and method for validating a wireless beacon location stored in a wireless beacon location record is actually proximate to the true location of the wireless beacon. The method includes: (a) receiving a wireless beacon location report with a wireless beacon identifier and a validation location; (b) correlating the wireless beacon location report with a wireless beacon location record by determining whether the beacon identifier in the wireless beacon location report matches the beacon identifier of a record in a plurality of wireless beacon location records; (c) determining whether the validation location received in the wireless beacon location report is proximal to the beacon location stored in the correlated wireless beacon location record, thereupon designating the wireless beacon location stored in the correlated wireless beacon location record as validated.

## Claims

### Claim 1

A method for validating a wireless beacon location stored within a wireless beacon location record, said wireless beacon location record comprising said wireless beacon location, a beacon identifier and a beacon revalidation indicator; the method comprising:
a) receiving from a device a wireless beacon identification report comprising a beacon identifier and a beacon revalidation indicator;
b) correlating said wireless beacon identification report with a wireless beacon location record by determining whether the beacon identifier in said wireless beacon identification report matches the beacon identifier of a record in a plurality of wireless beacon location records;
c) determining whether the beacon revalidation indicator received in said wireless beacon identification report indicates the wireless beacon location in said correlated wireless beacon location record is not valid, thereupon continuing with the method further comprising:
(i) designating the wireless beacon location in said correlated wireless beacon location record as not validated;
(ii) setting the beacon revalidation indicator in said correlated wireless beacon location record to the received revalidation indicator;
(iii) sending a wireless beacon location request to said device;
(iv) receiving a wireless beacon location report comprising a beacon identifier and a validation location;
(v) correlating said wireless beacon location report with a wireless beacon location record by determining whether the beacon identifier in said wireless beacon location report matches the beacon identifier of a record in a plurality of wireless beacon location records; and
(vi) determining whether the validation location received in said wireless beacon location report is proximal to the wireless beacon location stored in said correlated wireless beacon location record, thereupon designating the wireless beacon location stored in said correlated wireless beacon location record as validated.

### Claim 2 (depends on 1)

The method of claim 1 wherein said beacon revalidation indicator comprises an event counter value and wherein step (c) determines the validity of the wireless beacon location in said correlated wireless beacon location record based on the received beacon revalidation indicator matching the beacon revalidation indicator of said correlated wireless location record.

### Claim 3 (depends on 1)

The method of claim 1 wherein said wireless beacon location in said wireless beacon location record comprises a latitude and longitude and said validation location comprises a latitude and longitude.

### Claim 4 (depends on 3)

The method of claim 3 wherein said wireless beacon location record further comprises a two-dimensional shape description.

### Claim 5 (depends on 1)

The method of claim 1 wherein said wireless beacon location in said wireless beacon location record further comprises an elevation and said validation location further comprises an elevation.

### Claim 6 (depends on 5)

The method of claim 5 wherein said wireless beacon location record further comprises a three-dimensional volume description.

### Claim 7 (depends on 1)

The method of claim 1 wherein said wireless beacon location record further comprises a beacon address.

### Claim 8

A system for validating a wireless beacon location stored within a wireless beacon location record, said wireless beacon location record comprising said wireless beacon location and a beacon identifier; the system comprising data processing apparatus coupled with a device; said data processing apparatus being operated such that it performs operations comprising:
a) receiving from a device a wireless beacon identification report comprising a beacon identifier and a beacon revalidation indicator;
b) correlating said wireless beacon identification report with a wireless beacon location record by determining whether the beacon identifier in said wireless beacon identification report matches the beacon identifier of a record in a plurality of wireless beacon location records;
c) determining whether the beacon revalidation indicator received in said wireless beacon identification report indicates the wireless beacon location in said correlated wireless beacon location record is not valid, thereupon continuing by performing further operations comprising:
(i) designating the wireless beacon location in said correlated wireless beacon location record as not validated;
(ii) setting the beacon revalidation indicator in said correlated wireless beacon location record to the received revalidation indicator;
(iii) sending a wireless beacon location request to said device;
(iv) receiving a wireless beacon location report comprising a beacon identifier and a validation location;
(v) correlating said wireless beacon location report with a wireless beacon location record by determining whether the beacon identifier in said wireless beacon location report matches the beacon identifier of a record in a plurality of wireless beacon location records; and
(vi) determining whether the validation location received in said wireless beacon location report is proximal to the wireless beacon location stored in said correlated wireless beacon location record, thereupon designating the wireless beacon location stored in said correlated wireless beacon location record as validated.
