1. An electronic unit for use with a drug delivery device and adapted to generate and handle drug delivery data of the delivery device and to transmit data items of the delivery data to a first data subscriber and to a second data subscriber, respectively, the electronic unit comprising:
a housing configured to removably attach to the drug delivery device;
at least one sensor arranged in the housing and communicatively coupled to the drug delivery device, the at least one sensor configured for collecting the delivery data associated therewith; and
a processor with associated memory arranged in the housing and communicatively coupled to the at least one sensor, the processor having:
access to a first encryption key and a second encryption key associated with the first data subscriber and the second data subscriber, respectively, and
access to a first data allocation scheme and to a second data allocation scheme indicating to which delivery data item or items the first data subscriber and second data subscriber have respectively subscribed;
wherein, upon receipt of the delivery data from the sensor, the processor of the electronic unit is configured:
to prepare first transmit data including at least one delivery data item according to the first data allocation scheme defining a first subset of delivery data, and to encrypt the first transmit data based on the first encryption key;
to prepare second transmit data including at least one delivery data item according to the second data allocation scheme defining a second subset of delivery data different from the first subset and to encrypt the second transmit data based on the second encryption key; and
to cause transmission of the encrypted first transmit data and the encrypted second transmit data to the first data subscriber and the second data subscriber, respectively.
