Attention les yeux ! Première analyse "en direct" d'une solution "en double anonymat" qui fait sa pub sur Linkedin, pour vérifier l'age des personnes accédant Š un site pornographique : AnonymAge !
On rappelle que le double anonymat, c'est que le site porno n'apprend pas l'identité de l'utilisateurice et l'application de vérification n'apprend pas le site visité.
Deuxième étape de la vérification : on prend son téléphone, on lan…

Procédure de vérification en 3 étapes. La seconde étape consiste en un QRcode affiché par dessus le site visité, et qui doit être capturé par son téléphone faisant tourner l'appplication AnonymAge.

Hello, won't you tell me your name?: Investigating Anonymity Abuse in IPFS
The InterPlanetary File System~(IPFS) offers a decentralized approach to file storage and sharing, promising resilience and efficiency while also realizing the Web3 paradigm. Simultaneously, the offered anonymity raises significant questions about potential misuse. In this study, we explore methods that malicious actors can exploit IPFS to upload and disseminate harmful content while remaining anonymous. We evaluate the role of pinning services and public gateways, identifying their capabilitie…

Content warning: Spiders and Titanic: The Oddest Pairing You Didn’t See Coming

Warning for anyone scared of spiders or the Titanic wreck!
Spiders used to terrify me so much I couldn’t even sleep. I overcame it by doing what they call exposure therapy, just googling spiders and looking at pictures until it felt less scary. Now, I actually want to own a tarantula as a pet, which is kind of funny.
Something I’m even more scared of is the Titanic wreckage. It’s a oddly specific weird fear, but I think it’s a specific kind of Submechanophobia, where the fear is …

Close-up macro photo of a jumping spider on a bright green leaf. The spider’s body is covered in fine light-brown and grey hairs, giving it a fuzzy look. Its large, iridescent purple and red jaws stand out, facing forward. Two big, bright green eyes add an almost alien appearance. The spider’s thick, hairy legs have dark tips. The background is softly blurred green and blue, focusing attention on the spider’s detailed features. The image shows the spider’s beauty up close without being threaten…
The photograph shows a section of the wrecked RMS Titanic on the ocean floor, focusing on rusted and corroded railings and deck structures. Marine growth like sea anemones, sponges, and small white invertebrates cover the metal, creating a textured surface in rusty orange, brown, and grey-white tones. The railing is twisted and broken, with a dark sea fan-like organism attached. The scene is dark and somber, surrounded by deep ocean gloom. It evokes a strong sense of decay, time passing, and n…

Self-Equivalent Voting Rules
In this paper, I introduce a novel stability axiom for stochastic voting rules, called self-equivalence, by which a society considering whether to replace its voting rule using itself will choose not do so. I then show that under the unrestricted strict preference domain, a voting rule satisfying the democratic principles of anonymity, optimality, monotonicity, and neutrality is self-equivalent if and only if it assigns to every voter equal probability of being a dictator (i.e., uniform random …

Network Hexagons Under Attack: Secure Crowdsourcing of Geo-Referenced Data

Network Hexagons Under Attack: Secure Crowdsourcing of Geo-Referenced Data
A critical requirement for modern-day Intelligent Transportation Systems (ITS) is the ability to collect geo-referenced data from connected vehicles and mobile devices in a safe, secure and anonymous way. The Nexagon protocol, which builds on the IETF Locator/ID Separation Protocol (LISP) and the Hierarchical Hexagonal Clustering (H3) geo-spatial indexing system, offers a promising framework for dynamic, privacy-preserving data aggregation. Seeking to address the critical security and privacy v…
