Abstract: The disclosure is concerned with privacy and integrity of personalized protected health information when transmitted to a cloud computing facility and subsequently distributed to a plurality of stakeholders. An electronic unit of a drug delivery device is configured to prepare payload data comprising data items according to an allocation scheme, and to encrypt, based on an encryption key, and transmit data including the payload data. The allocation scheme and the encryption key are defined for each of a plurality of data subscribers. Accordingly, personalized protected health information payload data is suitably protected with generator-to-subscriber or pass-through data security measures, and any intermediary node or data server in the communication network lacking a matching decryption key will not have access to unencrypted payload data.

Abstract: Computer implemented methods for supporting an operation of a drug delivery device include the steps of: capturing, by a camera of a mobile device, a marker representative of a position of the drug delivery device; transmitting, by the mobile device, camera data of the camera relating to the captured marker to a provider; providing in response to the transmitted camera data, by the provider, drug delivery device data to the mobile device; displaying, by the mobile device, in a camera preview the received drug delivery device data, wherein the displaying may be controlled by a projection of the marker. The drug delivery device data includes instructions to a user relating to an operation of the drug delivery device.
