One Picture is Worth a Thousand Words: A New Wallet Recovery Process
Hervé Chabannne, Vincent Despiegel, Linda Guiga
We introduce a new wallet recovery process. Our solution associates 1) visual passwords: a photograph of a secretly picked object (Chabanne et al., 2013) with 2) ImageNet classifie…
Premium Access to Convolutional Neural Networks
Julien Bringer, Hervé Chabanne, Linda Guiga
Neural Networks (NNs) are today used for all our daily tasks; for instance, in mobile phones. We here want to show how to restrict their access to privileged users. Our solution re…
A Protection against the Extraction of Neural Network Models
Hervé Chabanne, Vincent Despiegel, Linda Guiga
Given oracle access to a Neural Network (NN), it is possible to extract its underlying model. We here introduce a protection by adding parasitic layers which keep the underlying NN…
Transforming face-to-face identity proofing into anonymous digital identity using the Bitcoin blockchain
Daniel Augot, Hervé Chabanne, Olivier Clémot +1
The most fundamental purpose of blockchain technology is to enable persistent, consistent, distributed storage of information. Increasingly common are authentication systems that l…
A User-Centric System for Verified Identities on the Bitcoin Blockchain
Daniel Augot, Hervé Chabanne, Thomas Chenevier +2
We present an identity management scheme built into the Bitcoin blockchain, allowing for identities that are as indelible as the blockchain itself. Moreover, we take advantage of B…
Biometric Systems Private by Design: Reasoning about privacy properties of biometric system architectures
Julien Bringer, Herve Chabanne, Daniel Le Metayer +1
This work aims to show the applicability, and how, of privacy by design approach to biometric systems and the benefit of using formal methods to this end. Starting from a general f…
