METHOD AND SYSTEM FOR SECURING THE MISMATCH, THE MISMATCHING AND THE DISTRIBUTION OF VECTOR VISUAL SEQUENCES

摘要

P The present invention relates to a method for the secure distribution of vector visual synthetic sequences at least two dimensions, animated and consisting of a succession of frames containing at least one multidimensional geometric object to be displayed on the screen of the user and determined by at least one parameter [color, scale, dimensions, point coordinates of the object]. Before the transmission to the client equipment, a flow analysis is carried out to generate a modified main flow, having the format identical to the format of the original flow but at least one frame of which has been modified, and additional information d 'Any format, including digital information capable of allowing the reconstruction of said modified frames, said modified main stream and said additional information thus generated from the server being transmitted separately to the recipient equipment. Subsequently, a summary of a stream in the original format is calculated on the recipient equipment as a function of said modified main stream and of said additional information. /P
