Abstract: 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.
