CA 2615714

A method for detecting state changes between data stored in a first computing device and data retrieved from a second computing device includes: generating a first hash value of the data stored in the first computing device; generating a second hash value of corresponding data retrieved from the second computing device; comparing the first hash value to the second hash; and detecting a state change in the event of a difference therebetween.

L'invention concerne un procédé permettant de détecter des changements d'état entre des données stockées sur un premier dispositif informatique et des données provenant d'un second dispositif informatique. Ledit procédé consiste: à générer une première valeur de hachage d'une donnée stockée sur le premier dispositif informatique; à générer une seconde valeur de hachage correspondant à une donnée extraite du second dispositif informatique; à comparer la première et la seconde valeur de hachage; et à détecter un changement d'état en cas de différence entre les deux valeurs.
