Abstract:
1. A method of authenticating images and particularly images of offending vehicles comprising the following steps: allocating image capturing systems ( providing informative system means to capture physical information relative to the offence, hereafter called offence data ( providing first memory and/or transmission means ( providing operating systems ( the operating systems apply to the captured image data, any known processing suitable for improving or conserving the quality of the images in question and/or reducing the amount of data necessary for reconstruction of the images, without any significant loss of quality, in order to reduce the size of the memories necessary for storing the captured image data and/or the capacity of the means for transmitting this data, the intermediate data representative of images after these processing being called initial graphical data ( the operating systems operated to calculate from the offence data and from a graphical representation of the alphanumerical characters ( the operating systems merging the initial graphical data and the graphical offence data in such a way as to obtain a new set of data representative of images, called graphical identifier-data ( the operating systems operated to calculate, by applying a non-bijective function, denoted f, to the graphical identifier data, a set of data, hereafter called summary data ( the operating systems operated to calculate, from the signature data and from a graphical representation of the alphanumerical characters constituting the signature data, new data representative of images, called graphical signature data ( the operating systems merging the graphical identifier data and the graphical signature data so as to obtain a new set of data representative of images, in which the graphical identifier data and the graphical signature data constitute sub-sets accessible from this new set of data, called graphical authenticable data ( providing second means of memorization and/or of transmission ( providing control units ( the control units searching among the graphical received data for the subset of graphical identifier data, hereafter called tested graphical identifier data ( the control units searching among the received graphical data, for the subset of graphical signature data, hereafter called tested graphical signature data ( the control units operated to calculate a set of data, called tested summary data ( the control units applying to the tested signature data, the method of decoding c.sup.−1 to obtain a set of data, called received summary data (
