Byzgen: onChain secrets implementation

ByzGen provide a backend platform (Falkor) that enhances applications and processes, allowing our clients to meet the increasing requirement for data to be shared securely and effectively across boundaries and organisations.

Covata, a leading Data Management business with a substantial presence in Australian Government, have successfully integrated Falkor with their Security application. The integration will further enhance their capability to support cross-organisation collaboration utilising sensitive data, enabling their clients to implement trust and bridge historic data silos.

A key component of the Falkor platform is the onChain secrets service, provided by C4DT-affiliated DEDIS laboratory, which can be used to re-encrypt the most sensitive of data and ensure that any reads to that data are validated, via a distributed and consensus driven decryption process.

CHUV: MedCo Project

MedCo, developed in the lab of EPFL professor Jean-Pierre Hubaux in collaboration with professor Bryan Ford’s DEDIS lab and the Lausanne University Hospital (CHUV), is the first operational system that makes sensitive medical-data available for research in a simple, privacy-conscious and secure way. It enables hundreds of clinical sites to collectively protect their data and to securely share them with investigators, without single points of failure.

MedCo applies advanced privacy-enhancing techniques, such as:

  • Collective homomorphic encryption;
  • Secure distributed protocols;
  • Blockchains;
  • Differential privacy.

ICRC: Digitalization as Enabler to Re-Connect Families in Time of War

More than one million families are separated due to conflicts. The ICRC and the EPFL through C4DT partnership have set themselves a challenge to analyse publicly available data through analytics techniques to identify missing persons that would arguably not have been identified using current, conventional methods. The goal of this project is to facilitate the search for missing individuals by building scalable, accurate systems tailored for that purpose.

Digital information can be exploited to make the search for missing persons significantly more successful and efficient and could help to resolve cases, particularly using algorithmic-based searches, facial recognition technology and connected platforms. Respecting privacy and data protection is essential to ensure that the approach does not imperil personal safety and that the ICRC -as a trusted expert organization- endeavours to “do no harm” and minimize the risk to persons. The ICRC will then resolve these cases according to the best interests of individuals, respecting safety and data protection standards.
