Bart van der Sloot (PI.lab)



Simone van der Hof (UL)

Framing citizen’s identities revisited: in 2009 we finished a study on the construction of personal identities in digital government. Ten years on: to what extent do our findings still stand given current developments in digital data-driven government?





Job Spierings (Waag)

Digital Identity Lab: a social dialogue on invisible infrastructure? There’s a huge need for a digital “identity” that is accessible and understandable. But technology is inherently complicated and autonomy requires a certain level of understanding and agency. How can we balance those (and other) conflicting requirements? Who decides, and why? An update on the learnings from the projects Decode & Digitale Identiteitslab.





Oskar van Deventer (TNO)

Self Sovereign Identity (SSI): This presentation shows how verifiable credentials can be used in interactions between patient, doctor, pharmacist and insurer, each switching roles between “issuer”, “holder” and “verifier”. The presentation will look into developing SSI standards from W3C Credentials Community Group, DIF, Hyperledger Indy and Hyperledger Aries, and SSI infrastructure service, most notably Sovrin.





Marjolein Lanzing (RU)

Empowerment: Commercial self-tracking technologies promise to empower us. But, can they really strengthen our autonomy when they commodify our data and steer our behaviour at the same time? In my dissertation I explore how commercial self-tracking technologies reshape our social relationships and the way we understand ourselves and what this means for living an autonomous and flourishing life.




Esther Keymolen (TILT)

What does it mean to be a smart city citizen? Cities are becoming smart. Data-driven applications are implemented to ensure safety and facilitate a smooth city life. This talk will explore how these smart city applications impact some of the core aspects of being a citizen. How do we interact with strangers, build trust, and participate in a public environment that is increasingly datafied?








PI.lab Quarterly event

Data and Truth symposium
26 April 2019; Boothstraat 7, Utrecht
Register for free via info@pilab.nl

As governmental organisations and businesses rely more and more on data, the relationships and tensions between the data-reality and the physical-reality become quintessential. Both may diverge, while the data-reality increasingly determines who we are, what our options are and how we are perceived by others. But what is true, who determines that and what are the consequences of the fact that relationships are constantly mediated? Computer says no, but why? Should you be able to erase your past using the right to be forgotten, or is that falsifying history? And can you escape your own profile when the police, tax authorities, insurers and banks alike use statistical correlations and probabilistic predictions to organise their conduct? These are the questions that will be central to our next PI.lab event.

12.00-13.00: Lunch
13.00-13.10: Bart van der Sloot: Welcome
13.10-13.40: Anna Poletti: We are the inscribers and the inscribed: thinking privacy and identity through autobiography studies
Trained in literary studies and philosophy at La Trobe and Newcastle Universities in Australia, Anna's research focus is contemporary forms of life narrative, with a particular interest in youth cultures, ephemera (both digital and analogue) and the role of mediation and materiality in autobiography. Drawing on feminist and queer theory traditions, Anna's published work examines how the materiality of media forms - from handmade postcards, to the selfie - inform the presentation of stories from lived experience. She has expertise in research methods that engage with ephemeral materials, queer and feminist theory, and comparative media studies. In her presentation, she discuss the insights contained in her forthcoming book.
13.40-14.00 Discussion

14.00-14.45: Rein Jelle Terpstra: Reality, media and perception
In his work, he constantly challenges the role of the medium itself, its impact on memory and perception and the relationship between the photographer and the photographed. In his work, Looking at the seeing, Terpstra asks how much of what we see is determined by how we look, and to what extent our knowledge and imagination influence what we see. His project Retracing is a wider investigation into perception, memory, photography, and the absence of image, as is his project After Images. And in his most recent project, he turns the camera, from the life event everyone is watching, to the audience.
14.45-15.00: Discussion
15.00-15.15 Break
15.15-15.45: Paulan Korenhof: Memory, knowledge and technology
During her research, Paulan has built up a keen and critical interest in the industrialization of "our" online collective memory, and more particular in the social effects of interface design and control, as well as in the implications that the current praxis of the "internet giants" has on power and knowledge (in)balances. Her main goal is to (help) build bridges between theory and practice in order to make sure that technology works for us, and not the other way around. In her presentation, she will explain the role of the internet and other technologies and their relation to knowledge, memory and power.
15.45-16.00: Discussion
16.00-16.30: Stephan Raaijmakers: Humans, AI and information quality
Stephan Raaijmakers (PhD in AI-based natural language processing) is working on Explainable AI at TNO, with a particular focus on communicative, interactive AI. In his presentation, he will outline different divisions of labor between humans and (deep learning-based) AI that enhance the quality and reliability of both information and AI. Cases will be presented from domains like security and health. How can humans play an active and sustainable role in the current AI transition and contribute to better information and AI? Which requirements apply to AI for facilitating humans in this role?
16.30-16.45: Discussion

16.45-17.15: Sascha van Schendel: Group profiles and Predictive Policing
As an expert in her field, Sascha specializes in human rights protection against Big Data use of governmental actors. Her PhD research deals with Big Data analytics by law enforcement agencies and issues of transparency. In her presentation, she will discuss the use of group profiles and predictive profiles for predictive policing, engaging with examples from the United States of America. In addition, she will explain what the current legal framework is for predictive policing taking into account the General Data Protection Regulation, the Law Enforcement Directive, the EU Charter of Fundamental Rights and other documents.
17.15-17.30: Discussion
17.30-18.30: Drinks

PI.lab Quarterly Event

Blockchain and privacy

Date: 22 November 2018

Location: Zaalverhuur7 - Boothstraat 7 - 3512 BT Utrecht

Registration: Entrance is free for all

Please, register by sending an email to info@pilab.nl (Irma Haerkens)

13.00-13.10: Bart van der Sloot - Welcome

13.10-13.30: Mireille Hildebrandt (Vrije Universiteit Brussel, Radboud Universiteit)

Mireille Hildebrandt will briefly discuss a set of myths that are often framed as ‘innate' properties of blockchain applications, notably the idea of an egalitarian consensus mechanism, of ‘innate’ immutability and irreversibility, the idea of trestles computing and the notions of publicness and transparency. She will then argue that for each concrete application a triple test must be conducted: (1) which problem is solved (compared to status quo and alternative solutions), (2) which problem is not solved (idem), and (3) which problem is created (idem). She will conclude with a brief discussion of design-based regulation and ‘legal protection by design’.

13.30-13.50 Discussion

13.50-14.10: Jaap-Henk Hoepman (Radboud Universiteit )

"The blockchain dissected" What are blockchains/distributed ledgers? How do they work? And what are their (claimed) properties? We will dissect the blockchain and address these questions. We will pinpoint certain fundamental pitfalls surrounding blockchain technologies, and ask ourself the question: is there any use for them?

14.10-14.30: Discussion

14.30-14.45: Break

14.45-15.05: Maarten Everts (TNO)

Smart contract says No - Smart contracts are hyped to take on the role of incorruptible, trustable third parties. However, the “immutability” that makes this possible also means that mistakes in smart contracts can have a significant impact. How are smart contracts different from “normal” software? What are the dangers? Is it possible to keep the human in the loop?

15.05-15.25: Discussion

15.25-15.45: Michelle Finck   (Max Planck Institute for Innovation and Competition)

The paper examines smart contracts from the perspective of Article 22 GPDR. It suggests that smart contracts likely qualify as a form of solely automated data processing and are hence caught by the qualified prohibition under Article 22 GDPR. It then evaluates the consequences flowing from that state of affairs and suggests that current efforts of sophisticating these tools may have a side-effect of GDPR compliance'.

15.45-16.05: Discussion

16.05-16.20: Break

16.20-16.40: Maurice Schellekens  (Tilburg University)

‘Asking the right question(s) about blockchain: does the law actually regulate technology?’


16.40-17.00: Discussion

17.00-17.30: General debate

17.30-18.30 Drinks
