Abstract

Systems and methods of registration of an anonymous tag having an owner with a location service include authenticating a tag sensor associated with the owner of the tag with the location service. The tag is placed within a defined transmission distance of the tag from the tag sensor associated with the owner. The tag is activated while it is within the defined distance from the tag sensor to initiate transmission of the self identification. The transmitted self identification is received at the tag sensor to detect the tag. It is determined that the detected tag is not yet registered with the location service and an identification of the tag and the owner is transmitted to the location service from the tag sensor to register the tag as belonging to the owner at the location service to limit registration of the tag at the location service.

Claims

1. A computer-implemented method of registration of an anonymous tag having an owner with a server comprising a location service that is configured to provide location information for moveable objects coupled to tags, wherein the tag is configured to transmit a self identification over a defined distance using a short range wireless protocol, wherein a tag sensor associated with the owner of the tag is configured to receive the self identification using the short range wireless protocol and configured to communicate with the server comprising the location service, the method comprising:

authenticating the tag sensor associated with the owner of the tag with the server comprising the location service, the location service being configured to provide the location information for the moveable objects coupled to the tags by transmitting, to the owner of the tag, a notification comprising a geographical location of a first mobile terminal that is not associated with the owner of the tag without identifying the first mobile terminal, the first mobile terminal being configured to receive the self identification from the tag and to provide the geographical location to the server;

placing the tag within the defined distance from the tag sensor associated with the owner;

activating the tag while it is within the defined distance from the tag sensor to initiate transmission of the self identification;

receiving the self identification of the tag at the tag sensor to detect the tag and receiving an additional self identification of another tag;

comparing a signal strength of the self identification of the tag with a signal strength of the additional self identification of the another tag;

determining based on the comparison that the signal strength of the self identification of the tag is greater than the signal strength of the additional self identification of the another tag;

determining that the detected tag is not already registered with the location service; and

transmitting an identification of the tag and the owner to the location service from the tag sensor to register the tag as belonging to the owner at the location service to limit registration of the tag at the location service based on the determination that the signal strength of the self identification of the tag is greater than the signal strength of the additional self identification of the another tag and based on the determination that the detected tag is not already registered with the location service,

wherein the registration of the tag is allowed only when the tag is unregistered,

wherein activating the tag comprises turning on power to the tag within the defined distance from the tag sensor, before the tag sensor detects the tag, and

wherein turning on the power to the tag comprises turning on the power to the tag using an actuator that cannot be reset to turn the power to the tag off so that the tag will continue transmission of the self identification until a battery included in the tag is discharged.

2. The method of claim 1, wherein the tag sensor comprises a second mobile terminal.

3. The method of claim 2, wherein the method further comprises determining that the another tag is already registered with the location service and not registering the another tag as belonging to the owner at the location service based on the determination that the another tag is already registered with the location service.

4. The method of claim 2, wherein transmitting the identification is preceded by:

presenting the identification of the tag on a display of the second mobile terminal; and

receiving a selection of the displayed identification as belonging to the owner, wherein transmitting the identification is only carried out responsive to receiving the selection of the displayed identification.

5. The method of claim 2, wherein determining whether the tag is registered includes:

receiving a message at the tag sensor from the location service indicating that the tag is already registered to another owner; and

then

determining a confidential ownership code for the tag that is only provided to a lawful owner of the tag; and

transmitting the ownership code to the location service to un-register the tag so that the tag is not associated with the another owner at the location service.

6. The method of claim 2, wherein transmitting the identification of the tag to the location service from the tag sensor is followed by transmitting a request to un-register the tag to the location service from the tag sensor to allow the tag to be registered as belonging to another owner.

7. The method of claim 2, wherein transmitting the identification of the tag to the location service from the tag sensor is followed by transmitting a permission from the tag sensor to another tag sensor that authorizes another owner associated with the another tag sensor to obtain information related to the tag from the location service.

8. The method of claim 2,

wherein the tags each include a visible public code associated therewith and each have a self identification, and

wherein transmitting the identification of the tag to the location service from the tag sensor is followed by retrieving the visible public code for each of the tags from the location service for use in differentiation visually between the tags.

9. The method of claim 1, wherein authenticating the tag sensor comprises initiating an IP-formatted communication between the tag sensor and the location service, before the tag is registered with the location service as belonging to the owner and before turning on power to the tag.

10. The method of claim 1, further comprising presenting the tag on a display of the tag sensor only when the tag is unregistered.

11. A first mobile terminal that is associated with an owner of a tag comprising:

a processor; and

a communication interface coupled to the processor and configured to;

communicate over a wide area network with a server comprising a location service that is configured to provide location information for moveable objects coupled to respective tags by transmitting, to the owner of the tag, a notification comprising a geographical location of a second mobile terminal that is not associated with the owner of the tag without identifying the second mobile terminal, the second mobile terminal being configured to receive a transmitted self identification from the tag and to provide the geographical location to the server; and

receive transmissions from the tag in the vicinity of the first mobile terminal and additional transmissions from another tag in the vicinity of the first mobile terminal using a short range wireless protocol,

wherein the processor is configured to receive, using the communication interface, the transmitted self identification to detect one of the tags as a detected tag when the detected tag is activated in the vicinity of the first mobile terminal, to receive an additional transmitted self identification of the another tag, to compare a signal strength of the self identification of the detected tag with a signal strength of the additional transmitted self identification of the another tag, to determine based on the comparison that the signal strength of the self identification of the detected tag is greater than the signal strength of the additional transmitted self identification of the another tag, to determine that the detected tag is not yet registered with the location service, and to transmit, using the communication interface, an identification of the tag and the owner of the tag to the location service to register the tag as belonging to the owner at the location service to limit registration of the tag at the location service based on the determination that the signal strength of the self identification of the detected tag is greater than the signal strength of the additional transmitted self identification of the another tag and based on the determination that the detected tag is not yet registered with the location service,

wherein the registration of the tag is allowed only when the tag is unregistered,

wherein activating the tag in the vicinity of the first mobile terminal comprises turning on power to the tag within the vicinity of the first mobile terminal, before the first mobile terminal detects the tag, and

wherein turning on the power to the tag comprises turning on the power to the tag using an actuator that cannot be reset to turn the power to the tag off so that the tag will continue transmission of the self identification until a battery included in the tag is discharged.
