Abstract

An apparatus, a computer program and a method in an apparatus for causing obtaining from a wireless charging detector (220) an indication of the presence of a wireless charging field; causing obtaining from a near field communication circuitry (210) an indication of proximity of a near field communication device (1 10, 120); and responsively to obtaining the indications, causing negotiating with the near field communication device (1 10, 120).

Claims

1. An apparatus, comprising:

a near field communication circuitry;

a wireless charging station detector;

at least one processor; and

at least one non-transitory memory including a computer program code; and

an access controller configured to allow access to information stored in the non-transitory memory according to predefined access information, wherein the predefined access information comprises a rollback counter, wherein the rollback counter is used as a communication freshness guarantee to ensure that only changed information is transferred,

wherein the at least one non-transitory memory and the computer program code are configured, with the at least one processor, to cause the apparatus to;

obtain from the wireless charging detector an indication of the presence of a wireless charging field;

obtain from the near field communication circuitry an indication of proximity of a near field communication device; and

in response to obtaining the indication of proximity of the near field communication device, negotiate with the near field communication device based at least in part on the rollback counter, wherein the negotiating is performed by near field communication.

2. The apparatus of claim 1, configured to obtain its operating power by the near field communication circuitry.

3. The apparatus of claim 1, wherein the processor is configured to establish a communication session with the near field communication device, in response to the negotiating resulting in authorizing of one of the apparatus and the near field communication device to access the other one of the apparatus and the near field communication device.

4. The apparatus of claim 3, wherein the processor is configured to cause exchanging of information between the apparatus and the near field communication device in the communication session, wherein the exchange of information is in response to the obtaining of the indications.

5. The apparatus of claim 3, wherein the communication session is established for near field communication.

6. The apparatus of claim 1, wherein the access information further comprises party specific access information including a party identification.

7. The apparatus of claim 1, wherein the access information comprises memory segment specific access information, wherein the memory segment specific access information comprises memory segment specific read permission flags.

8. The apparatus of claim 1, wherein the apparatus further comprises a tag device that is semi-passive device, wherein a semi-passive is capable of storing energy for autonomous operations;

and the apparatus further comprises;

a user interface that includes at least one of a display, keys, and a touch surface.

9. The apparatus of claim 1, wherein the access information comprises a one-directional cryptographic hash code.

10. The apparatus of claim 1, wherein comprising information comprises memory segment specific edit permission flags, wherein the memory segment specific access information comprises at least one of a pointer to an access code for reading permission, a pointer to an access code for writing permission, and a pointer to an access code for editing permission.

11. The apparatus of claim 10, wherein the apparatus comprises one of a source apparatus and a target apparatus and the editing permission allows the source apparatus to move a segment metadata content to the target apparatus.

12. The apparatus of claim 11, wherein at least one suitable segment is searchable in the target apparatus based on at least one edit flag, wherein the at least one suitable segments includes a segment that is editable by the source apparatus;

and

the source apparatus is operable to dump a source segment data in a suitable target segment in the target apparatus and to lock up the suitable target segment.

13. The apparatus of claim 1, wherein the access controller is configured to authorize the near field communication device based on the access information based on a test to determine if an access code has been used by the near field communication device as at least one of an encryption key and a part of an encryption key to encrypt the rollback counter.

14. The apparatus of claim 1, wherein the at least one non-transitory memory and the computer program code are further configured, with the at least one processor, to cause the apparatus to:

determine, based on at least one property, whether the apparatus is to cause a near field communication circuitry associated with the apparatus to signal at least portion of the party specific access information to the near field communication device and is to be configured to perform write and read operations on the near field communication device.

15. The apparatus of claim 14, wherein the at least one property includes at least one of an internet protocol (IP) address, media access control (MAC) address, uptime, availability of external power;

battery level, a property indicating whether the apparatus is an active device; and

a rollback counter value.

16. A method comprising:

obtaining from the wireless charging detector an indication of a presence of a wireless charging field, by an apparatus that includes a wireless charging detector and an access controller configured to allow access to information stored in the non-transitory memory according to predefined access information, wherein the predefined access information comprises a rollback counter, wherein the rollback counter is used as a communication freshness guarantee to ensure that only changed information is transferred;

obtaining from a near field communication circuitry an indication of proximity of a near field communication device;

in response to obtaining the indication of proximity of the near field communication device, negotiating with the near field communication device based at least in part on the rollback counter, wherein the negotiating is performed by near field communication; and

obtaining operating power for the apparatus by the near field communication circuitry.

17. The method of claim 16, further comprising;

establishing a communication session with the near field communication device, in response to the negotiating resulting in authorizing of one of the apparatus and the near field communication device to access the other one of the apparatus and the near field communication device; and

exchanging information between the apparatus and the near field communication device in the communication session.

18. A computer program product, comprising at least one non-transitory computer readable storage medium having a computer readable program code portion stored thereon, the computer readable program code portion comprising:

code for obtaining from a wireless charging detector an indication of a presence of a wireless charging field, by an apparatus that includes the wireless charging detector and an access controller configured to allow access to information stored in the non-transitory memory according to predefined access information, wherein the predefined access information comprises a rollback counter, wherein the rollback counter is used as a communication freshness guarantee to ensure that only changed information is transferred;

code for obtaining from a near field communication circuitry an indication of proximity of a near field communication device; and

code for, in response to obtaining the indication of proximity of the near field communication device, negotiating with the near field communication device based on the rollback counter, wherein the negotiating is performed by near field communication.
