J’ai lu sur Macworld la pr\u00e9sentation d’une boite qui propose des photos certifi\u00e9s<\/a>.<\/p>\n

L’id\u00e9e, c’est de mettre des syst\u00e8mes de protections, permettant de garantir que la photo a bien \u00e9t\u00e9 prise \u00e0 un endroit donn\u00e9, \u00e0 une date donn\u00e9e.<\/p>\n

\u00e7a, ok, mais si on me pr\u00e9sentait une telle preuve, ma r\u00e9action serait assez simple : qu’est-ce qui me garanti que la photo est une photo \u00ab\u00a0directe\u00a0\u00bb ou qu’il s’agit d’une photo de photo ?<\/p>\n

Et oui, rien n’interdit de placer une photo devant l’appareil.<\/p>\n

La seule solution pour emp\u00eacher \u00e7a serait d’ajouter des informations sur la profondeur de champ par exemple, sauf que je ne pense pas que l’Iphone permette cela, pas plus que les autres mobiles.<\/p>\n

J’avais d\u00e9j\u00e0 exprim\u00e9 mes doutes aux fondateurs de cette startup. Ils m’avaient r\u00e9pondu que je devais \u00eatre particuli\u00e8rement tordu pour imaginer un tel sc\u00e9nario ;).<\/p>\n

Alors, la preuve \u00e9lectronique est une bonne id\u00e9e, mais l’iPhone n’est sans doute pas le support id\u00e9al, et je doute que de tels supports fassent foi devant la justice. en tout cas, \u00e7a ne remplace certainement pas un huissier.<\/p>\n

Peut \u00eatre que, pour faire cette application, il vaudrait mieux partir d’un appareil photo connect\u00e9 et int\u00e9grant un GPS ?<\/p>\n","protected":false},"excerpt":{"rendered":"
