Description

PROCEDE D'EXTENSION DES CAPACITES D'ENCODAGE DU CODE A BARRES PDF 417METHOD FOR EXTENSION OF PDF BARCODE ENCODING CAPACITIES
Le secteur technique de la présente invention est celui des procédés d' identification automatique à l'aide de codes à barres comme par exemple le code connu sous la désignation PDF 417.The technical sector of the present invention is that of automatic identification methods using bar codes such as for example the code known under the designation PDF 417.
En 1996, ce code à barres PDF connaît un retentissement extraordinaire aux Etats unis d'Amérique avec la fourniture de lecteurs associés.In 1996, this PDF barcode had an extraordinary impact in the United States of America with the supply of associated readers.
Ce code à barres est connu pour procurer une grande capacité d'encodage de données, ce qui n'est pas le cas des codes à barres classiques largement répandus. Cette capacité d' encodage est telle que ce code à barres n'est pas non plus quantitativement différent mais qualitativement différent des autres outils d'identification. Son rôle d'identification ne consiste plus à appeler des données, mais à les fournir directement, avec une fiabilité et des coûts de possession des systèmes très concurrentiels par rapport à ceux mis en œuvre dans des technologies différentes comme les cartes à puce, les cartes PCMCIA, ou les étiquettes radio.This bar code is known to provide a large capacity for encoding data, which is not the case with conventional bar codes widely used. This encoding capacity is such that this bar code is not quantitatively different but qualitatively different from other identification tools. Its identification role is no longer to call data, but to provide it directly, with reliability and cost of ownership of systems very competitive compared to those implemented in different technologies such as smart cards, cards PCMCIA, or radio tags.
Toutefois, dans l'espace de besoins que les symbologies bi-dimensionnelles ont créé, la limite des 1 000 octets du code à barres PDF 417 reste sans commune mesure avec les autres supports précédemment cités. Pour plus de détails on peut se reporter au document édité par « Association Indentification Manufacturers » dans UNIFORM SYMBOLOGY SPECIFICATION PDF 417.However, in the space of needs that the two-dimensional symbologies have created, the limit of 1000 bytes of the PDF 417 barcode remains incommensurate with the other media previously mentioned. For more details, see the document published by “Association Indentification Manufacturers” in UNIFORM SYMBOLOGY SPECIFICATION PDF 417.
On sait déjà répartir et retrouver une information sur plusieurs codes à barres PDF 417. Mais la lecture doit être faite dans l'ordre exact de codage de l'information pour obtenir un message cohérent. De plus, lorsque l'information est de type binaire, on a constaté une perte se traduisant par une reconnaissance par le système d'un code à barres de commande qui conduit à des perturbations . Enfin, il n'y a aucune possibilité de contrôle de l'intégrité de 1' information.We already know how to distribute and find information on several PDF 417 barcodes. But reading must be done in the correct order of coding the information to get a consistent message. In addition, when the information is of binary type, a loss has been observed, resulting in recognition by the system of a control bar code which leads to disturbances. Finally, there is no possibility of checking the integrity of the information.
C'est pourquoi l'objet de l'invention vise la création d'un nouvel assemblage à base de codes à barres PDF 417 dont la capacité d'encodage ne présente plus de limite mathématique mais uniquement physique, et permettant l'utilisation de lecteurs du commerce sans aucune adaptation. L'invention a donc pour objet un procédé d'extension des capacités d'encodage de données à l'aide du code à barres PDF 417 après une première étape classique de compression des données, les données étant lues par un matériel d' acquisition en liaison avec un matériel de lecture connecté à un système d'information, caractérisé en ce qu'on répartit à l'aide d'algorithmes les données en une série de codes à barres liés dynamiquement pour réaliser une seconde compression, on introduit un élément de contrôle de l'intégrité de l'information et on commande le formatage et la lecture des données directement à partir du système d'information.This is why the object of the invention is to create a new assembly based on PDF 417 bar codes, the encoding capacity of which no longer has a mathematical limit but only a physical limit, and which allows the use of readers. trade without any adaptation. The subject of the invention is therefore a method of extending data encoding capacities using the PDF 417 bar code after a first conventional step of data compression, the data being read by acquisition equipment in connection with reading equipment connected to an information system, characterized in that the data is distributed using algorithms in a series of bar codes dynamically linked to achieve a second compression, an element of control of the integrity of the information and the formatting and reading of the data are controlled directly from the information system.
Selon une caractéristique de l'invention, on répartit les données par paquets de 1 Ko quel que soit leur volume.According to a characteristic of the invention, the data is distributed in packets of 1 KB whatever their volume.
Selon une autre caractéristique, le système d'acquisition et l'application en réception des données sont intégrés au système d' information auquel est connecté le matériel de lecture.According to another characteristic, the acquisition system and the application for receiving data are integrated into the information system to which the reading material is connected.
Un avantage essentiel de l'invention réside dans le fait que le volume des données lues n'est pas assujetti à un matériel de lecture spécifique et au volume de sa mémoire.An essential advantage of the invention lies in the fact that the volume of the data read is not subject to specific reading material and to the volume of its memory.
Un autre avantage réside dans l'absence de contrainte de l'ordre de lecture des codes à barres PDF. D'autres caractéristiques, détails et avantages de l'invention apparaîtront plus clairement à la lecture du complément de description donné ci-après donné à titre indicatif en relation avec un dessin sur lequel la figure unique 1 représente un schéma d'organisation. Comme indiqué précédemment, on s'affranchit des limites actuelles des lecteurs du commerce en assurant autant de transmissions que de lectures, en reconstituant les données au niveau de la mémoire vive du calculateur et en mettant en oeuvre des algorithmes de compression/décompression faisant appel aux fractales et des algorithmes de cryptage des données .Another advantage lies in the absence of constraints on the order of reading PDF bar codes. Other characteristics, details and advantages of the invention will appear more clearly on reading the additional description given below, given for information only, in relation to a drawing in which the single figure 1 represents an organizational diagram. As indicated above, we overcome the current limits of commercial readers by ensuring as many transmissions as reads, by reconstructing the data in the computer's RAM and by implementing compression / decompression algorithms using fractals and data encryption algorithms.
Il est ainsi possible d'utiliser un lecteur standard du commerce qui n' est pas saturé par le volume des données qu' il a à transmettre à un calculateur intégré dans le matériel d'acquisition, puis au système d'information. Un seuil supplémentaire est alors franchi, c'est l'augmentation des capacités de l'encode et du décode.It is thus possible to use a standard commercial reader which is not saturated by the volume of data which it has to transmit to a computer integrated in the acquisition equipment, then to the information system. An additional threshold is then crossed, it is the increase in the capacities of the encoder and of the decode.
Pour aller au-delà des limitations du lecteur, on codifie une quantité de données illimitée répartie en une série de symboles liés dynamiquement. Chaque symbole représente alors une quantité donnée de la codification globale. La liaison dynamique permet d' éviter les erreurs de manipulation, comme par exemple l'inversion de l'ordre de lecture, la double lecture accidentelle ou la non validation en cas d'oubli d'un symbole. On peut par exemple répartir l'ensemble des données sur un ensemble de quatre symboles. On lit ensuite ces quatre symboles et on recompose l'information au niveau du système d'information. On comprend qu'avec cette nouvelle méthode ce n'est plus ni le matériel d'acquisition des données, ni le lecteur par exemple, qui interprètent l'information, mais le système d'information lui-même, ce qui revient à reporter l'interprétation au niveau d'une puissance de calcul sans commune mesure avec la capacité intrinsèque du lecteur. Le rôle de cette puissance de calcul est alors de recréer la structure de l'information à partir de chaque paquet qui porte la description des liens avec l'ensemble complet des paquets. Il en résulte que le procédé selon l'invention permet l'utilisation de matériels périphériques du commerce sans modification particulière. Le procédé selon l'invention permet de dépasser les limites physiques et mathématiques du code à barres PDF 417 décrit selon les normes en vigueur, ce qui permet de traiter des volumes d' information très importants en restant compatibles avec les moyens d'impression et de lecture du commerce. C'est donc un avantage tout à fait considérable qu' apporte l'invention. De plus, les codes à barres peuvent être lus sans aucun ordre et certains codes à barres peuvent être lus deux fois sans aucune perturbation du système et sans aucune perte d'intégrité de l'information.To go beyond the limitations of the reader, one codifies an unlimited quantity of data distributed in a series of dynamically linked symbols. Each symbol then represents a given quantity of the global coding. The dynamic link allows avoid handling errors, such as reversing the reading order, accidental double reading or non-validation in case of forgetting a symbol. We can for example distribute all the data on a set of four symbols. We then read these four symbols and recompose the information at the information system level. We understand that with this new method it is no longer either the data acquisition equipment or the reader, for example, which interpret the information, but the information system itself, which amounts to reporting interpretation at the level of a computing power without common measure with the intrinsic capacity of the reader. The role of this computing power is then to recreate the structure of the information from each packet which carries the description of the links with the complete set of packets. It follows that the method according to the invention allows the use of commercial peripheral equipment without any particular modification. The method according to the invention makes it possible to exceed the physical and mathematical limits of the PDF 417 bar code described according to the standards in force, which makes it possible to process very large volumes of information while remaining compatible with the printing and reading the trade. It is therefore an entirely considerable advantage which the invention brings. In addition, bar codes can be read without any order and some bar codes can be read twice without any system disturbance and without any loss of information integrity.
A titre d'exemple, on peut intégrer dans quatre codes à barres PDF 417 un volume d'information de l'ordre du 800 Ko. Ainsi donc, on réalise une première compression des données de manière classique, puis on réordonne l'information compressée en paquets d'information à l'aide de fonctions polynomiales pour réaliser une seconde compression et on introduit une instruction de contrôle de parité de l'intégrité. En décompression, on relit d'abord l'intégration à l'aide du système d'information, un micro ordinateur par exemple, puis on interprète l'information et on obtient l'information initialement compressée. Le mode d'intégration est donc reconnu dans l'outil d'interprétation et de décompression.As an example, we can integrate into four PDF 417 barcodes a volume of information of the order of 800 KB. So, we perform a first compression of the data in a conventional manner, then we reorder the compressed information into information packets using polynomial functions to perform a second compression and we introduce a parity check instruction of the integrity. In decompression, we first re-read the integration using the information system, a microcomputer for example, then we interpret the information and we obtain the information initially compressed. The integration mode is therefore recognized in the interpretation and decompression tool.
On restitue à l'inverse une grande quantité de données de façon transparente et sécurisée pour l'utilisateur final.Conversely, a large amount of data is restored in a transparent and secure manner for the end user.
Sur la figure 1, on a représenté l'organisation d'un système faisant application du procédé selon l'invention. Le système d'information 1 est un programme dédié qui encode et décode les données en étant connecté à un matériel d'acquisition 2, par exemple un micro ordinateur, incorporant un calculateur 3. Le matériel 3 est relié à une imprimante 4 qui imprime un ou des codes 5 à barres PDF 417 résultant de l'encodage des données de départ. A l'inverse, le code à barres PDF 417 peut être lu par un lecteur 6 qui est connecté au matériel d' acquisition 2 dont les données sont décodées par le système d' information 1 pour restituer sous forme lisible l' information contenue dans le code à barres PDF 417. Si les codes sont multiples aucun ordre de lecture, comme indiqué précédemment, n' est imposé et le système ne délivre aucune information tant que la lecture de tous les codes n'est pas réalisée au moins une fois. In Figure 1, there is shown the organization of a system applying the method according to the invention. The information system 1 is a dedicated program which encodes and decodes the data while being connected to acquisition equipment 2, for example a microcomputer, incorporating a computer 3. The equipment 3 is connected to a printer 4 which prints a or PDF 417 bar codes 5 resulting from the encoding of the initial data. Conversely, the PDF barcode 417 can be read by a reader 6 which is connected to the acquisition equipment 2, the data of which are decoded by the information system 1 in order to reproduce in readable form the information contained in the PDF barcode 417. If the codes are multiple, no reading order, as indicated above, is imposed and the system does not deliver any information until all the codes have been read at least once.
