Worldcoin Foundation has advanced data security
through secure multi-party computation, deletes old iris codes
The Worldcoin Foundation today announced it launched and is open
sourcing a novel secure multi-party computation (SMPC) system. The
system, available now in a GitHub repository for any organization
to use, aims to set a new standard for data protection, including
the protection of biometric data. The Worldcoin Foundation also
announced that, after the migration of iris codes to the new SMPC
system, the previous uniqueness-checking system, including iris
codes, was securely deleted.

Biometric authentication use increases as data breach
frequency and impact rise
Organizations in the private and public sector increasingly
require and use consumers’ biometric data for everyday services and
activities, from building access and airport security to logging
into healthcare and financial services apps. Underscoring the
increase, a Fortune Business Insights report projected the global
biometric system market size to reach $76.70 billion USD in 2029,
2.5x its total of $30.77 billion in 2022.
Meanwhile, research from MIT Professor Stuart Madnick indicates
a 20% increase in data breaches from 2022 to 2023 while globally
the number of victims of such breaches doubled over the same time
period.
The convergence of these trends suggests a need to further
advance data protection technologies. While Worldcoin is neither an
authentication nor an identification use case for biometrics (the
Worldcoin Foundation does not know the identity of their users),
the Foundation’s new open source SMPC system can serve as a
building block to set a new standard in biometric data
security.
Worldcoin Foundation’s SMPC system
SMPC has been lauded by privacy and security experts alike. It
can be thought of as taking one secret and sharing it in multiple
parts across different parties for increased protection.
Importantly, none of the individual parts alone say anything about
the original secret, thus making it impossible for any individual
party to decrypt the secret.
This SMPC approach demonstrates perfect information-theoretic
security, meaning it is effective even against quantum-computing.
SMPC systems have generally been too resource-intensive to be
effectively used for large complex computations. This is why,
despite their impressive privacy protective qualities, they have
not yet seen extensive use in biometric template protection.
The Worldcoin Foundation, along with contributor-technologists
from TACEO and Tools for Humanity, have successfully architected a
new implementation of SMPC to address the scale and cost
constraints that have previously hindered others. The new SMPC
system, which encrypts iris codes into secret shares held by
multiple parties, enabled the Worldcoin Foundation to permanently
delete iris codes generated through its previous
uniqueness-checking system.
“The community supporting Worldcoin will never stop developing,
testing and deploying the most advanced technologies focusing on
security, privacy and data protection as it works to improve trust
online and increase access to the global economy,” said Jannick
Preiwisch, Data Protection Officer of the Worldcoin Foundation.
“Implementation of the new SMPC system enabled the Worldcoin
Foundation to delete old iris codes by permanently encrypting them
to SMPC shares that by themselves cannot be related to an
identified person. The development of this new system demonstrates
an unparalleled commitment to further compliance with the EU
General Data Protection Regulation and other data protection
regimes across the world. It also complements advancements aimed at
providing consumers increased choice and control over their data
including personal custody and the ability to unverify their World
IDs.”
