Manel Jerbi<\/h1>\n\n\n\n

Chercheuse postdoctorale<\/strong> \u00e0 l\u2019Universit\u00e9 du Luxembourg<\/strong><\/p>\n\n\n\n

Manel Jerbi est chercheuse postdoctorale au sein du groupe SaToSS (Security and Trust of Software Systems) de l\u2019Universit\u00e9 du Luxembourg. Elle a obtenu en 2021 un doctorat en informatique \u00e0 l\u2019Universit\u00e9 de Tunis, consacr\u00e9 \u00e0 la d\u00e9tection des malwares Android \u00e0 l\u2019aide de techniques d\u2019optimisation \u00e9volutive et de motifs artificiels. Ses travaux actuels portent sur la confidentialit\u00e9 diff\u00e9rentielle, la synth\u00e8se de graphes sociaux et les probl\u00e9matiques de pr\u00e9servation de la vie priv\u00e9e dans les donn\u00e9es de r\u00e9seaux. Elle a publi\u00e9 sur la d\u00e9tection de malwares et sur la protection de donn\u00e9es dans les r\u00e9seaux sociaux h\u00e9t\u00e9rog\u00e8nes, et s\u2019int\u00e9resse particuli\u00e8rement aux approches combinant mod\u00e8les formels, optimisation et s\u00e9curit\u00e9.<\/p>\n\n\n\n

Title: Synth\u00e8se de graphes sociaux et confidentialit\u00e9 diff\u00e9rentielle: principes, d\u00e9fis et applications<\/strong><\/p>\n\n\n\n

Les graphes sociaux sont largement utilis\u00e9s pour analyser les relations, mod\u00e9liser les interactions ou \u00e9tudier des r\u00e9seaux r\u00e9els tels que les communications, les r\u00e9seaux sociaux ou les collaborations scientifiques. Pourtant, leur diffusion ou leur exploitation soul\u00e8ve de forts risques de r\u00e9identification : m\u00eame apr\u00e8s suppression des identifiants, la structure du graphe peut suffire \u00e0 reconna\u00eetre des individus ou r\u00e9v\u00e9ler des informations sensibles.<\/p>\n\n\n\n


Cette pr\u00e9sentation introduira d\u2019abord les \u00e9l\u00e9ments de base des graphes sociaux : structure, types de r\u00e9seaux, propri\u00e9t\u00e9s locales et globales, ainsi que les principales menaces li\u00e9es \u00e0 leur publication.<\/p>\n\n\n\n


Nous aborderons ensuite les fondements de la confidentialit\u00e9 diff\u00e9rentielle, ses d\u00e9finitions cl\u00e9s et les m\u00e9canismes adapt\u00e9s aux graphes. Une attention particuli\u00e8re sera port\u00e9e \u00e0 la synth\u00e8se de graphes sous confidentialit\u00e9 diff\u00e9rentielle, approche permettant de g\u00e9n\u00e9rer des r\u00e9seaux artificiels pr\u00e9servant des caract\u00e9ristiques statistiques pertinentes tout en prot\u00e9geant les individus du graphe original.<\/p>\n\n\n\n

Des exemples concrets illustreront les compromis entre utilit\u00e9 des donn\u00e9es et protection de la vie priv\u00e9e, les avantages de la g\u00e9n\u00e9ration synth\u00e9tique, ainsi que les limites actuelles et d\u00e9fis ouverts (qualit\u00e9 structurelle, scalabilit\u00e9, h\u00e9t\u00e9rog\u00e9n\u00e9it\u00e9).<\/p>\n\n\n\n
