A system and method for managing memory in a mobile device to prevent the swapping out of sensitive data to non-volatile storage from a volatile memory, to provide enhanced security for the sensitive data. In one broad aspect, there is provided a method of managing memory in a mobile device comprising the steps of identifying one or more data objects stored in a volatile memory on the mobile device to be swapped out to a non-volatile storage component, determining objects marked as containing sensitive data, and retaining so-marked objects in the volatile memory of the mobile device.

La présente invention a trait à un système et un procédé pour la gestion de mémoire dans un dispositif mobile pour empêcher l'extraction avec permutation de données sensibles vers une mémoire non volatile depuis une mémoire volatile, en vue d'assurer une sécurité améliorée pour les données sensibles. Dans un aspect très large, il est prévu un procédé de gestion de mémoire dans un dispositif mobile comprenant les étapes d'identification d'un ou de plusieurs objets mémorisés dans une mémoire volatile sur le dispositif mobile à extraire avec permutation vers un composant de mémoire non volatile, de détermination d'objets identifiés comme contenant des données sensibles, et le maintien de tels objets identifiés dans la mémoire volatile du dispositif mobile.
