Writing and reading data system, starting from a chromatic printed information that modifies patterns emitted by an electromagnetic waves source, introducing biases that conform new patterns, giving place to new data categories matched to a code

DESCRIPTION

Data writing and reading system, based on chromatic printed information that modifies patterns emitted by a source of electromagnetic waves, introducing polarizations that form new patterns, giving rise to new categories of data that correspond to a code.

Field of the invention 5

The present invention relates to a system for recording and reading data, in which the encoded data is set on a variety of media (cards, tickets, vouchers, notes, etc.) made of different materials (paper, cardboard, plastic , rubber, and many others). That information becomes inaccessible to human vision and, due to its particular conditions of production is impossible to access unless destroying or causing damage to the support, and therefore the appropriate information becomes impossible to duplicate or clone. This system provides 10 improved security levels.

Recording and reading processes are characterized by low production costs.

Background of the invention

At present there are many recording and reading solutions for the data card market (smart cards, RFID cards, magnetic cards, bar codes, etc.), and although they are not part of the universe of electronic reading, there are also cards scratches that are used to hide information.

US 2005/067489 A1, US 4 464 786 A, GB 2 121 959 A, US 6 242 733 B1 and WO 96/23274 A1 describe electronic systems for authentication and / or identification of cards or media, such as document identification or paper money. Such systems comprise an electromagnetic emitter, a photoelectric transceiver and a microprocessor. twenty

Such modalities are either high in cost or have poor performance, allowing forgery and cloning.

This invention, instead, provides a data support solution for those markets and applications, providing lower cost and higher security standards.

Compendium of the invention 25

According to the present invention a system according to claim 1 is provided in which the encoded data is stored in a medium by use by depositing material that has chromatic properties on or incorporating it into the medium and such data is read by passing electromagnetic radiation through said medium or reflecting such radiation from such medium and wherein the radiation waveform is modified by interaction with said material having chromatic properties. 30

The present invention is a very high security data storage system, which, by means of a process to establish groupings of chromatic patterns (which can be installed by means of standard printing resources) on supports made of paper, cardboard, plastic, rubber , etc., allows data to be set in a very subtle color distribution form, making visual detection and mechanical access to chromatic patterns (pigmented molecules) installed in a support layer impossible and known as 35 data values ​​impossible. This procedure allows the later detection (reading) of particular characteristics of an electromagnetic wave after its interaction with such chromatic material, given by a convergence of several physical phenomena, such as shape changes, harmonic distributions, distortions and index variations. absorption at different frequency exposures, with its consequent impact on the potential response of the system, and resonance effects that occur at the level of the original electromagnetic wave. Together, such values ​​are parameterized and combined in an array, causing a complex data record, and allowing reference (correspondence) to a given code of data categories. Then the result is compared to a standard record (a sample) and, if it is identical, it is validated as a genuine data element.

The electromagnetic radiation used for this purpose may typically be in the visible range but may also be for example in the infrared, microwave and ultraviolet regions of the spectrum if suitable chromatic materials are used. Such radiation will normally be at a particular predetermined wavelength. When a light source is used, it may conveniently be a light emitting diode. If desired, multiple sources of electromagnetic radiation can be used to "read" different data elements present in the medium. Such sources can be used at different times and their interaction with chromatic clusters evaluated against the same or different sets of parameters that result from the interaction of electromagnetic radiation and chromatic clusters. In this sense, different aspects of the data stored in the medium can be read for different purposes.

Chromatic materials suitable for use in the present invention include conventional inks and toners, the effect of which has been determined when interacting with electromagnetic radiation of particular waveforms.

The medium to which such groupings can be applied includes paper, cardboard, acetate, plastic, plexiglass, acetate, rubber, adhesive tape and cloth. If desired, multiple layers can be used each of which may contain chromatic groupings representing different data elements.

As noted above, an interaction of electromagnetic radiation with a grouping of material that has chromatic properties can cause a variation of a number of different parameters relative to the waveform. The number of parameters used to perform a verification according to the present invention will be a choice, depending for example on the degree of security required.

The process explained above is repeated for each of the data elements in the sample, and if one does not satisfy the matrix comparison requirements (parameters) the sample will be invalid. The data represented by a chromatic grouping can be stored in any convenient analog or digital form. 10

The detection process is done, for example by means of photoelectric transformation, producing a binary or analog output, which is decoded by a suitable processing block.

The color deposits on or in the support medium can be made in any convenient way, for example printing. Preferably, the safety is improved by subtle variation within the reservoir thereby causing a more complex modification of electromagnetic radiation that interacts with the chromatic reservoir 15. The variation within the color groups is made by using mixtures of materials that have color properties in each color group.

The detection of the modified waveform parameters is achieved in a convenient manner, for example by the use of transducers and photoelectric cells. A comparison with an authentic set of parameters that have been predetermined for a particular chromatic grouping is then carried out by computer means, for example by the use of a microprocessor.

Detailed description of the preferred embodiments

Referring generally to Fig. 1, starting from an electromagnetic energy source (such as a light emitter 35 for this example) 1, a photonic emission set is produced having a specific waveform and wavelength selected between the entire electromagnetic spectrum 2, passing through a protection layer 3, and continuing to the data layer containing chromatic installations formed in controlled clusters 4.

These groupings, which form molecular deposits, add information that comes from the modification of the original 40 characteristics (waveform, etc.) of the original photonic emission.

As a result, the emerging beams 6, 7 and 8, due to a distortion modification resulting from the interaction with the chromatic deposits, contain a new harmonic distribution giving rise to new waveforms, and thus creating a new register of information. These beams are received by the photoelectric transceiver (scanner) 9, then the analog output information 10 is processed by the microprocessor 11. This module 45 decodes the information, comparing the data with internal data, validating each bit or not, and then controlling the interfaces 12, 13, 14 and 15, affected to final and external processes.
