Assignee: CVS PHARMACY, INC.
Field: Medical technology (Instruments)
Classification: CPC G  A  H | IPC A  G  H

Claim 7:
8. A system, comprising:
a processor;
a memory;
a health activity unit, stored in the memory for execution by the processor, comprising instructions for:
detecting a health activity of a user, wherein:
the health activity is based on a user interaction related to a healthcare need and a hardware device of the user;
the health activity unit comprises a plurality of interface modules fora the plurality of hardware devices;
the plurality of interface modules includes an interface module for the hardware device of the user; and
each interface module of the plurality of interface modules comprises:
a hardware device interface for a different hardware device associated with a patient; and
a protected health information control unit for at least one user of the different hardware device;

sending, responsive to detecting the health activity of the user, a request for a first protected health information address to a blockchain health cloud;
receiving the first protected health information address for the user;
identifying health data associated with the health activity, wherein the identified health data comprises protected health information;
identifying a task to be performed based on the health activity and the identified health data, wherein:
the task comprises adding the identified health data to a health data blockchain associated with the health activity;
the health data blockchain comprises a plurality of data blocks, wherein each data block comprises:
a blockchain address for that data block;
blockchain data; and
blockchain code; and

each protected health information control unit includes at least one data block of the plurality of data blocks in the health data blockchain;

determining, based on a first data block of the health data blockchain and the protected health information control unit associated with the hardware device of the user, whether the user is an authorized user of the identified health data;
responsive to the user being authorized, determining a health activity state from a second data block of the health data blockchain;
performing the task using the identified health data for the authorized user, wherein performing the task comprises:
updating the health activity state from the second data block;
creating, based on the blockchain data of the second data block, a third data block to add the identified health data to the health data blockchain, wherein the third data block comprises a smart contract in the blockchain code of the third data block for controlling access to the identified health data;
sending the third data block to the blockchain health cloud;
receiving, responsive to sending the third data block to the blockchain health cloud, a contract address for the health data; and
locking data access to the identified health data using the contract address;
adding a new data block to the health data blockchain to update the health activity state from the second data block;
propagating and validating the new data block across the protected health information control units; and
generating, based on the plurality of interface modules and the new data block, a user interface for the plurality of hardware devices with a unified view of the updated health activity state.
