Handling information
A communication method, for use with a telecommunications system, enables special communications to be routed to respective devices in a group of the devices by addressing the devices with a respective special identifier. The telecommunications system includes a network core and a plurality of subscriber devices registered with the network core. The core enables communications to be routed to the devices by a respective ID allocated to each device. The method further includes maintaining a store of the special identifier of each device in the group and a corresponding value derived from the ID. The method enables the special identifier of a device in the group to be obtained from the store by providing the store with the corresponding value derived from that device's ID.
1. A method of making available data to a second user device, which data relates to a first user device identified by a network ID in a telecommunications network, comprising:
receiving from the first user device, at a non-transitory computer readable data store operated by a third party communication server, a first corresponding value of the first user device derived from the network ID of the first user device, wherein the network ID cannot be derived from the first corresponding value by the third party communication server;
associating, using at least one processor, said data in the non-transitory computer readable data store with the first corresponding value, wherein the non-transitory computer readable data store does not have access to the network ID; and
enabling said data to be retrieved by the second user device, using at least one processor, from the non-transitory computer readable data store, wherein the enabling said data to be retrieved includes:
receiving from the second user device, at the non-transitory computer readable data store, a second corresponding value of the first user device derived from the network ID of the first user device wherein the network ID cannot be derived from the second corresponding value, wherein the third party communication server is separate from a network core of the telecommunications network with which the first user device is subscribed, and
retrieving said data associated with the first corresponding value based on a comparison of the first corresponding value and the second corresponding value, wherein said data is retrieved when the second corresponding value is the same as the first corresponding value.
2. The method of claim 1 , wherein said network ID is stored by the second user device.
3. The method of claim 1 , wherein at least one of the first and the second corresponding values is derived from the network ID by encryption performed using a hashing algorithm.
4. The method of claim 1 , wherein the network ID is a personal identifier.
5. The method of claim 1 , wherein the network ID is an MSISDN.
6. The method of claim 1 , wherein at least one of: the first user device and the second user device comprises a device having a client application installed thereon and wherein the client application provides the non-transitory computer readable data store with one of the first or second corresponding values derived from the network ID.
7. The method of claim 1 , wherein the third party communication server is separate from a network core of the telecommunications network with which the second user device is subscribed.
8. The method of claim 1 , wherein the deriving at least one of the first and second corresponding value from the network ID is performed by irreversible encryption of said network ID.
9. A system for making available data to a second user device, which data relates to a first user device identified by network ID in a telecommunications network, comprising:
a store, operated by a third party communication server, for:
storing said data,
receiving, from the first user device, a first corresponding value of the first use derived from the network ID of the first user device, wherein the network ID cannot be derived from the first corresponding value by the third party communication server, and
receiving, from the second user device, a second corresponding value of the first user device derived from the network ID of the first user device, wherein the network ID cannot be derived from the second corresponding value, and wherein the third party communication server is separate from a network core of the telecommunications network with which the first user device is subscribed,
wherein the store does not have access to the network ID and is operated by a third party communication server;
an associating device for associating said data in the store with the first corresponding value; and
a retrieving device for enabling said data to be retrieved by the second user device from the store by comparing the received first corresponding value and second corresponding value, wherein said data is retrieved when the second corresponding value is the same as the first corresponding value.
10. The system of claim 9 , wherein said network ID is stored by the second user device.
11. The system of claim 9 , wherein at least one of the first and the second corresponding values is derived from the network ID by encryption performed using a hashing algorithm.
12. The system of claim 9 , wherein the network ID is a personal identifier.
13. The system of claim 9 , wherein the core network ID is an MSISDN.
14. The system of claim 9 , wherein at least one of: the first user device and the second user device comprises a device having a client application installed thereon, and wherein the client application provides the store with one of the first and second corresponding values derived from the network ID.
15. The system of claim 9 , wherein the third party communication server is separate from a network core of the telecommunications network with which the second user device is subscribed.
16. The system of claim 9 , wherein the deriving at least one of the first and second corresponding value from the network ID is performed by irreversible encryption of said network ID.
