Digital image i.e. user photo, authenticating method for portable telephone, involves modifying blocks based on code so as to modify visual rendering of blocks, and decompressing modified image and displaying modified image on terminal
The method involves segmenting a digital image into blocks that are juxtaposed with respect to one another and not intersected with one another, and compressing the segmented image. The compressed image is stored in a secure storing and processing unit e.g. Universal Integrated Circuit Card (UICC)su...

| description | The method involves segmenting a digital image into blocks that are juxtaposed with respect to one another and not intersected with one another, and compressing the segmented image. The compressed image is stored in a secure storing and processing unit e.g. Universal Integrated Circuit Card (UICC)such as smart card, and numbers are allocated to the corresponding blocks. The blocks are modified based on a code containing the allocated numbers, so as to modify the visual rendering of the blocks. The modified image is decompressed and displayed on a terminal i.e. portable telephone. An independent claim is also included for a system for authenticating an image, comprising a portable telephone.
Procédé d'authentification d'une image (3) comprenant les étapes de : - (E1) partition de l'image (3) en tuiles (32) juxtaposées et sans intersection ; - compression de l'image (3) ainsi décomposée ; - stockage de l'image (3) dans une unité (2) de stockage et de traitement sécurisée sous forme compressée ; - attribution d'un numéro (36) à chacune des tuiles (32); - (E5) modification par l'unité (2) de stockage et de traitement sécurisée d'un premier ensemble de tuiles en fonction d'un code composé d'une série de numéros compris parmi les numéros attribués de manière à modifier ainsi sensiblement le rendu visuel de cet ensemble de tuiles ; - (E6) décompression et affichage de l'image (4) ainsi modifiée sur le terminal. |
