Early 2020, ID Side filed a WIPO-PCT patent application on the technology that covers the creation of the "Personal Data Choice Management Platform", including notably the use of “privacy-preserving” pseudonymous identifiers.

ID Side’s technology allows internet users to broadcast their default privacy choices to information technology providers. Conversely, it also allows these information technology providers to ask specific internet users to grant them an exception to these default privacy choices.

To enable this to work, information technology providers need a way to indirectly identify a specific internet user within the ID side system, so that these requests for an exception are routed to the correct individual. ID Side’s technology relies on a pseudonymous identifier to make this possible in API calls. This approach creates a potentially unexpected privacy risk: this pseudonymous identifier could be used by information technology providers to indirectly track users, somewhat like using a device address.

ID Side counters this risk by using cryptographic mechanisms that make the pseudonymous identifier change continuously, rendering it useless as a tracking tool.
