Programmable hearing device and method of programming a hearing device
The invention relates to a hearing device that comprises a data interface for receiving data and a memory unit for storing data. The memory unit comprises a non-static section and a static section. The static section comprises a unique key that is unique for the specific hearing device. The hearing device further comprises a verifier that is configured to process the unique key and a second key contained in first type data received via the data interface in order to determine whether the second key needs a verification criterion with respect to the unique key. The verifier is further configured to discard received first type data in the non-static section of the memory unit if the second key contained in received data does not meet the verification criterion with respect to the unique key stored in the static section of the memory unit.

4. The hearing device according to claim 1 , wherein the hearing device is a hearing aid that is configured to be head-worn by a person hard of hearing, wherein the non-static section of the memory unit or partition comprises data for controlling the operation of the processing unit with respect to processing the electric input sound signal and wherein the processing unit is configured to process the electric input sound signal according to parameter data and/or program code data stored in the non-static section of the memory partition or unit.
5. The hearing device according to claim 1 , wherein the hearing device is configured to provide non-activated additional functionality wherein the additional functionality is provided by the processing unit in combination with operation program code and/or operation parameter values stored in the non-static section of the memory unit or partition.
6. The hearing device according to claim 1 , wherein the verifier is configured to allow updating operating parameter values and/or operation program code if the second key does meet the verification criterion with respect to said unique key.
7. The hearing device according to claim 5 , wherein the hearing device is configured to activate additional functionality by way of updating operating parameter values and/or operation program code.
8. The hearing device according to claim 1 , wherein received data is comprised in a data package that comprises a header and payload data, wherein the header indicates the type of payload data.
9. A hearing device updating system comprising:
a hearing device according to claim 1 , said hearing device being configured to receive data packages containing payload data that represent changes and/or updates with respect to operation parameter values and/or operation program code;
a data package that comprises payload data representing changes and/or updates with respect to operation parameter values and/or operation program code; and
a delivery subsystem which is configured to transmit the data packages comprising data that represent updated operating parameters and/or program code that determine the operation of the hearing device.
10. The hearing device according to claim 2 , wherein the hearing device is a hearing aid that is configured to be head-worn by a person hard of hearing, wherein the non-static section of the memory unit or partition comprises data for controlling the operation of the processing unit with respect to processing the electric input sound signal and wherein the processing unit is configured to process the electric input sound signal according to parameter data and/or program code data stored in the non-static section of the memory partition or unit.
11. The hearing device according to claim 3 , wherein the hearing device is a hearing aid that is configured to be head-worn by a person hard of hearing, wherein the non-static section of the memory unit or partition comprises data for controlling the operation of the processing unit with respect to processing the electric input sound signal and wherein the processing unit is configured to process the electric input sound signal according to parameter data and/or program code data stored in the non-static section of the memory partition or unit.
12. The hearing device according to claim 2 , wherein the hearing device is configured to provide non-activated additional functionality wherein the additional functionality is provided by the processing unit in combination with operation program code and/or operation parameter values stored in the non-static section of the memory unit or partition.
