Description

[0009] The method will be explained in more detail using an exemplary embodiment. In the drawing shows:

[0010] FIG. 1: the schematic sequence of the method for authenticity control of indications of origin; and

[0011] FIG. 2: the schematic sequence of the method in the control of the durability of perishable products.

[0012] With the schematic representation of FIG. 1, a variant of the authenticity control of indications of origin in conjunction with the data for authentication of the original product is reproduced. By assigning an individual code for each product 1, the application of counterfeit indications of origin (e.g. trademarks) on products is largely ruled out. The introduction of the individual code takes place on the part of the surface of the product 1, on which the mark 3 is applied. The application is carried out in such a way that no visible optical design features of the brand 3 are changed. By means of laser beam method, the code is incorporated encrypted by different wells. These depressions, which cannot be perceived by mere observation, can also be introduced on the design surface 2 of the mark 3. In particular, this technically more complex variant for high-priced products 1, such as watches with notoriously known brand names, suitable. Likewise, in a further variant of the introduction of individual coding pattern are applied to the area of origin markings. Such coding patterns consist of dot-shaped invisible color elements which are combined as a pattern containing the code. As suitable colors for example invisible IR colors can be used. Likewise, in a further variant of the introduction of individual coding pattern are applied to the area of origin markings. Such coding patterns consist of dot-shaped invisible color elements which are combined as a pattern containing the code. As suitable colors for example invisible IR colors can be used. Likewise, in a further variant of the introduction of individual coding pattern are applied to the area of origin markings. Such coding patterns consist of dot-shaped invisible color elements which are combined as a pattern containing the code. As suitable colors for example invisible IR colors can be used.

[0013] For the purpose of authentic control, the detection of the design elements by means of a mobile computing device 4, such as a smart phone, tablet PC, notebook, by triggering the autofocus function. The peripheral edges of the design surface 2 to be tested are detected. Thereafter, the optical representation elements of the total area between the peripherally delimiting edges are two-dimensionally picked up by the camera of the mobile computing device 4. For the purpose of discriminating the two-dimensional and three-dimensional code features introduced in the origin identifier, the camera is moved relative to the inspected surface during the detection process. During the usually upward movement, acquisitions from different distances (heights) and/or angles are performed by software. If different views of the visual display elements are detected due to the different incidence of light, a three-dimensional design feature is present within the design area 2. The changes in the optical views of three-dimensional representations upon detection from different planes or angles of incidence of the light may be enhanced by thereby triggering the flashlight device and/or the flashlight function. Alternatively, instead of the movement upwards, the camera can also be made laterally and thereby change the respective detection angle of the camera. With a required higher accuracy of the detection of the design features, the respective detection takes place within the different distance levels by the software-assisted connection of the ZOOM function of the camera. From the design elements of the acquired overall view, the connection data are decoded from the respective individual codes recorded, to connect to the server 5 of the manufacturer via the Internet 7. After the connection has been established, the individual code and the data of the detected brand 3 are transmitted. The values decoded by the server 5 are then compared with stored values of the data of the genuine product. If the comparison results in a match of the values, a corresponding signal is transmitted to the mobile computer device 4 and signaled by the latter visually and/or acoustically as a genuine product. In this case, a query code 6 is transmitted, which also contains the query time and the release for the querying seller. If the comparison yields deviations of the values, then the presence of a counterfeit product is signaled by the mobile computer device 4. After the connection has been established, the individual code and the data of the detected brand 3 are transmitted. The values decoded by the server 5 are then compared with stored values of the data of the genuine product. If the comparison results in a match of the values, a corresponding signal is transmitted to the mobile computer device 4 and signaled by the latter visually and/or acoustically as a genuine product. In this case, a query code 6 is transmitted, which also contains the query time and the release for the querying seller. If the comparison yields deviations of the values, then the presence of a counterfeit product is signaled by the mobile computer device 4. After the connection has been established, the individual code and the data of the detected brand 3 are transmitted. The values decoded by the server 5 are then compared with stored values of the data of the genuine product. If the comparison results in a match of the values, a corresponding signal is transmitted to the mobile computer device 4 and signaled by the latter visually and/or acoustically as a genuine product. In this case, a query code 6 is transmitted, which also contains the query time and the release for the querying seller. If the comparison yields deviations of the values, then the presence of a counterfeit product is signaled by the mobile computer device 4.

[0014] The database of the server 5 contains the assignments of the mark 3 to the individual codes of the products land a query code 6 associated therewith. The data of the mark 3 and of the individual code are compared with the data of the database and the associated interrogation code 6 is determined. If the respective data associated with the product 1 match, the authenticity of the product is signaled. For each query, the query code 6 is recreated according to a predetermined stored mathematical function. Subsequently, the new polling code 6 is sent from the server 5 to the polling mobile computing device 4. The server 5 registers the query and stores the time and the number of queries already made. For the authenticity check, in addition to the trademark data with the individual code, the valid query code 6 must also be entered and transmitted. Even with a complete imitation of the original product with individual code and brand data so the confirmation of the authenticity can be done only with simultaneous knowledge of the currently valid query code 6. When querying the database also more product information such as technical data, a three-dimensional audiovisual representation of the product is available.

[0015] During the recording process of the individual code, a hash function integrated into the evaluation software is used, which converts the acquired value. This conversion makes it impossible to trace back to the individual code of the product land thus significantly increases the security against counterfeiting. The converted value is sent to the server 5.

[0016] Within the server 5, the appropriate values of the product 1 to be checked are also converted and stored using the same hash function. After the transfer of the detected and hash function coded values, these are compared with the stored values. If the comparison results in a match of the values, a corresponding signal is transmitted to the mobile computer device 4 and signaled by the latter visually and/or acoustically as a genuine product of the manufacturer. If the comparison yields deviations of the values, then the presence of a counterfeit product 1 is signaled by the mobile computer device 4.

[0017] The data connection between the origin marking (e.g. brand) and the individual code can be designed as a hologram, in which, for example, the brand representation and the code are components of the hologram. Furthermore, instead of the laser engravings or holograms or in addition to these code patterns in the form of punctiform patterns are used, which are produced by dot-shaped applications of invisible dots of infrared color. These are detected by the camera sensor of the mobile computing device 4 and displayed on the display. The code is decrypted by creating a template on the code pattern by querying only predetermined polling points of the applied code pattern. In order to increase the detection accuracy and the required exclusive reproduction of the IR image (pattern), an IR filter is arranged between the camera sensor and the code pattern to be detected, which hides the influence of daylight. The key for the respective locations of the code pattern to be queried is stored in the database and is sent to the mobile computing device 4 at the query from the data associations of the brand and individual connection code. This determines the values of the code pattern at the locations specified by the key and sends them to the database. After comparing the code thus decrypted, a comparison is then made with the valid stored values.

[0018] The schematic representation of FIG. 2 shows the procedural sequence of the process in the authenticity control and detection of the shelf life of perishable products such as food and pharmaceutical products as well as the time-related Functional guarantee of technical products. In this variant of the use of the method, the individual code is combined with the data of the indication of origin and the expiry date and this data is applied to the product 1 itself or the packaging. The code with the expiry date is printed on the surface of the product 1 or the packaging. For this purpose, in addition to or on the visible design features of the origin marking (trademark), the individual code is generated as a dot-shaped code combination by means of color dots of invisible IR color. The data of the code combination are then stored in the database II. At each over the Internet or the connection to a mobile data storage taking place query the stored data of the respective genuine product, a new query code 6 is generated. In addition to the code data, this also contains the date of the query and the number of queries already made. With this query code 6 ensures that only the interrogator can make a new query to the existing authenticity of the product 1, which is also in the possession of the respective valid query code 6. The individual security code serves to identify the respective originality or uniqueness of the product land the interrogation code 6 to prevent undiscovered imitations,

[0019] The storage of the shelf life data in a query carried out in another database 8 allows the overview and timely signaling of those products 1, for which a price discount is provided within predetermined periods.
