About me

François Chung | |

Currently, I am Functional Analyst at Zetes (BE). Prior to that, I have been working as a Scientific Software Engineer at CISTIB from UPF (ES), R&D Engineer in Intelligent Systems at Inspiralia (ES), Consultant in Energy Efficiency at E²=MC (BE), Consultant in Software Implementation at Sofico (BE), Business Analyst at FIS (BE), and Digital Business Analyst at Fujitsu (BE).

Since January 2011, I am Ph.D. in Computer Science from Mines ParisTech (FR). My Ph.D. was done at Asclepios, INRIA Sophia-Antipolis (FR). My thesis mainly deals with the analysis of medical images and took place within the framework of the EU Marie Curie project 3D Anatomical Human (3DAH).

Before starting my Ph.D., I took courses in computer vision and robotics at ViCOROB, UdG (ES). In 2005, I graduated Industrial Engineer in Computer Science (Ing./M.Sc.) from ISIB (BE).

Identity proofing

Identity proofing

|

Zetes project @Brussels, Belgium (2021). Identity proofing consists in verifying for a given level of assurance that a person, who is claiming an identity, is indeed the correct person. This identity proofing process can be performed manually by a human operator, either on site (through physical presence) or online (remotely through videoconference), but also automatically (e.g. fully automated online or in a controlled environment).

At the European level, the European Telecommunications Standards Institute (ETSI) is working on technical specification ETSI TS 119 46 to lay the foundations on a new identity proofing standard, whose aim is to be applicable in areas such as the issuance of electronic identity (eID) and Know Your Customer (KYC) processes, with several person types considered: natural person, legal person, and natural person representing a legal person.

One of the objectives of this specification is to provide controls against two main identity proofing threats:

  • Falsified evidence: A person claims an incorrect identity using forged evidence;
  • Identity theft: A person uses valid evidence associated with another person.

Therefore, implementing identity proofing requires a risk-based and outcome-based approach where requirements can be tuned up to a desired level of assurance (i.e. degree of certainty) of the result, depending on the context (e.g. purpose of the identity proofing, regulatory environment, acceptable risk regarding the result of the process).

In this project, my tasks are related to the analysis of technical specification ETSI TS 119 46 so as to investigate what parts of the identity proofing process are already developed and available at Zetes (and therefore could be reused), how the missing parts can be implemented in practice and what are the possible impacts of the implementation on the existing products and solutions.

PKI for identity documents

PKI for identity documents

|

Zetes project @Brussels, Belgium (2021). A Public Key Infrastructure (PKI) is a set of physical components (e.g. computers and hardware), human procedures (e.g. checks and validation) and software (e.g. system and applications) intended to manage the public keys of the users of a system. The objective is the secure electronic transfer of information for a range of online activities, such as e-commerce and electronic identification (eID).

In the case of electronic identity documents, such as the identity card, a PKI makes it possible to bind public keys to the identity of citizens, whose personal information is not only printed on the identity card, but also stored in the identity card chip. This system not only allows citizens to use their card to identify themselves online (authentication), but also to sign digital documents using a Qualified Electronic Signature (QES).

A PKI can also be used in an international scheme, such as for the verification of passports at country borders. In that case, a country emits passports for its citizens and also puts in place a PKI to allow other countries to check those passports. This means that, when a citizen presents a passport at the border control, the inspection system checks the identity information both printed on the passport and stored in the passport chip.

As a Functional Analyst and Product Owner within Zetes People ID’s development team, my tasks are related to the analysis of PKI software needs, whether internal or from the customer (e.g. requirement gathering and product presentation), PKI software implementation (e.g. software releases and documentation) and project management (e.g. project coordination during change requests).
