Apple has been granted a patent for “Privacy Preserving Logging.” It involves preserving the privacy of online health records.

About the patent

In the patent Apple says advancements have been made in recent years that allow users to download health data from remote electronic health record (EHR) systems to their mobile user devices. For example, a user may use their smartphone to connect to an endpoint of the EHR system and download a copy of their clinical health record. 

However, in some cases, such downloads and other uploads from the smartphone may pass through a service provider or other third-party server, which could raise privacy concerns. Apple’s patent involves techniques to deal with such issues.

Summary of the patent

Here’s Apple’s abstract of the patent: “A server system implemented by a service provider may store health data of a user according to a multi-node data structure. The server system may generate transaction records based on requests to access the health data. 

“Responsive to requests for the transaction records, the server system may query a database that includes the health data and generate a data package based on the querying. The data package may be sent to a requesting system. The data package may be usable by the requesting system to identify which patient profiles were accessed by which physicians.”
