A method for sharing a digital image between a first user terminal and at least one second user terminal over a communications network. The method includes: displaying on the second terminal a “degraded image”, the degraded image being obtained from a “first image” by digital processing of the first image, the digital processing visually concealing content of the first image; and following detection of an interaction of a user with the screen of the second terminal: defining a zone of interaction of the degraded image depending on the location of the interaction on the screen; obtaining a portion of the first image corresponding to the determined zone of the degraded image; and displaying on the screen of the second terminal the portion of the first image in the place of the corresponding area of the degraded image, throughout the duration of the interaction of the user with the screen.
