Rétro-ingénierie

La rétro-ingénierie, ou ingénierie inversée, est l'activité qui consiste à étudier un pour en déterminer le fonctionnement interne. On parle également de rétro-conception dans le domaine du vivant. Le terme équivalent en anglais est reverse engineering. vignette|La rétro-ingénierie. Définition formelle Il peut s'agir de :

comprendre le fonctionnement de l'objet, pour être en mesure de l'utiliser correctement, de le modifier, ou encore de s'assurer de son bon fonctionnement, le cas échéant dans un cadre pédagogique rappellent C. Berrou et V. Gripon (2012) ;
comprendre le fonctionnement et l'utilité d'un objet technique ancien, ou d'une œuvre d'art présentant des aspects techniques comme en archéologie et en archéologie industrielle ou dans le cadre de la restauration d’œuvres techniques anciennes ;
fabriquer une copie de cet objet alors qu'on ne peut en obtenir ni les plans ni les méthodes de fabrication (activité généralement illégale si l'objet est encore protégé

Machine Learning Techniques to address classification issues in Reverse Engineering

Jonathan Dekhtiar

This paper aims to provide a road map for future works related to reverse engineering field of expertise. Reverse Engineering, in a mechanical context, relates to any process working in a bottom-up fashion, namely that it goes from a lower level concept or product (closer to the final product) to a higher level one (closer to the ideation step). Nowadays, the manufacturing industry is facing unprecedented increase in data exchange and data warehousing. This comes with new issues that our work will not explore, such as "how to store these data in an efficient manner?", "what should be stored?" and so on. Nonetheless, this trend also creates new opportunities if we manage to integrate these data into the expertise workflows. In this paper we will cover the possibilities offered by machine learning to succeed in this challenge. We will also present a first and major step in our road map in order to achieve our research goals. We plan to design a metric to quantify how well and how precise can we perform some specific reverse engineering tasks such as detection, segmentation and classification of mechanical parts in imagery data. We aspire to open this metric; and make it freely and widely available to researchers and industry in order to compare the effectiveness, robustness and preciseness of the existing and future approaches.

Opacité et transparence dans le design d'un dispositif de surveillance urbain : le cas de l'IMSI catcher

Félicien Michel Marie Goguey

This thesis assesses the surveillance operated on the mobile phone network by governmental actors (intelligence agencies, police, army) and the relationship between monitored spaces and their users. Indeed, some new surveillance devices used by intelligence services redefine surveillance spatiality raising new questions in this field of research. More specifically this research focuses on one specific object: the IMSI catcher, a monitoring apparatus of the cellular network that intercepts cellphones' identity and some communications in a given area by mimicking the activity of a cell tower. While this kind of device seems to offer a tactical and a security interest in the fight against terrorism and against crime, many civil liberties organisations such as the Electronic Frontier Foundation, Privacy International and _La Commission nationale de l'informatique et des libertÃ©s are concerned about the potential of an uncontrolled surveillance ; indeed, the controversial nature of the device could endanger certain individual and public rights. What is this technical object and which new issues comes with its use in surveillance? How and from which perspective is it problematic What does the IMSI catcher teaches us on the potential future of surveillance regimes? I look into this specific device case in a research framework at the intersection of design research practices, science and technology studies (STS) and surveillance studies. First, I deal with this surveillance apparatus as a technical object, from a perspective fed by the theoretical framework of concretization and technical lines proposed by Gilbert Simondon and Yves Deforge, through the analysis of a visual and technical documentation. Second, I use a research by design approach to explore certain assumptions regarding the nature of the object itself, its functioning and its "concrete" aspect â or rather "non-concrete" in the present case â with the help of approaches borrowed to reverse engineering and reconstitution, close to media archeology. Then, I explore possible opposition and protest trajectories with the help of prototypes designed with critical design and speculative design methods. Finally, through the writing of prospective scenarios, I build a design fiction that offers a synthesis, potentially subject to debate, around the IMSI catcher's uses, present and to come, and more broadly on the potential future of surveillance regimes.
