TECHNICAL FIELDThe technical field generally relates to systems and methods for authentication of consumer products, and more particularly relates to systems and methods for authentication of consumer products based upon intrinsic features of the products or packaging material associated therewith.
BACKGROUNDCounterfeiting of articles such as documents, merchandise, and currency is a growing problem worldwide, and authentication of such articles has become increasingly important as counterfeiting capabilities have increased in sophistication. Recent developments have focused upon providing pre-configured security features such as 2D and 3D barcodes, indicia including engineered materials having authenticable properties such as magnetic and/or luminescent properties, RFID chips, and the like. However, such pre-configured security features often require specialized authentication systems for interrogation thereof. Further, such pre-configured security features may affect price and appearance of the articles associated with the security features.
While the pre-configured security features are often useful for retailers, banks, or other establishments, consumers are also often desirous of determining authenticity of consumer products, especially when purchasing brand-name goods that are widely subject to counterfeiting. However, consumers generally do not have access to specialized devices that are specifically adapted to authenticate pre-configured security features.
Recent develops with optical character recognition (OCR) have given rise to a variety of new services and capabilities using portable computing devices, such as smartphones and tablet computers. For example, remote bank check deposits are made possible using OCR technology and a camera of the portable computing devices. To deposit bank checks, the geometry of the bank check is recognized within a field of view of the camera. Following recognition of the bank check geometry, OCR is conducted on specific areas of the bank check to gather relevant information from the bank check. The gathered information is then employed by an electronic banking program to complete the financial transaction. While remote bank check deposit technology is very useful for financial transactions, such technology has limitations that impede broader implementation. For example, bank checks have a relatively simple, standard shape and fields subject to OCR are generally consistent between documents. Further, the bank check deposit technology fundamentally requires characters associated with the bank checks that are available for interrogation by OCR technology. Thus, such technology is not applicable to authenticity determinations based upon anything other than characters.
Accordingly, it is desirable to provide systems and methods for authentication of consumer products that are readily available to consumers. In addition, it is desirable to provide systems and methods for authentication of consumer products that do not rely upon pre-configured security features and that do not require specialized devices that are required to enable authentication of such pre-configured security features. Furthermore, other desirable features and characteristics will become apparent from the subsequent detailed description and the appended claims, taken in conjunction with the accompanying drawings and this background.
BRIEF SUMMARYSystems and methods for authentication of a consumer product are provided herein. An embodiment of a method for authentication of a consumer product includes providing the consumer product, optionally with packaging material associated therewith. Filtered light from an intrinsic portion of the consumer product or packaging material associated therewith is detected using a photodetector of a portable computing device to produce at least one single-color image data set representative of the intrinsic portion for at least one color. The at least one single-color image data set is compared with a stored data set that is representative of authentic information for the intrinsic portion using a microprocessor of the portable computing device. Comparing of the at least one single-color image data set with the stored data set is conducted independent of and separate from any analysis of non-color data obtained from preconfigured security features. An indication of authenticity of the consumer product is provided with the portable computing device based upon an outcome of comparing the at least one single-color image data set with the stored data set representative of authentic information for the intrinsic portion.
Another embodiment of a method of authentication of a consumer product includes providing the consumer product, optionally with packaging material associated therewith. Filtered light from an intrinsic portion of the consumer product or packaging material associated therewith is detected using a photodetector of a portable computing device to produce at least one single-color image data set that is representative of the intrinsic portion for at least one color. An independent indication of authenticity of the consumer product is registered in a database using the portable computing device. The database is populated with the at least one single-color image data set after registering the independent indication of authenticity.
In another embodiment, a system for authentication of a consumer product includes a portable computing device and a database. The portable computing device includes a microprocessor and a photodetector. The photodetector is configured to produce single-color image data sets representative of an intrinsic portion of the consumer product or packaging material associated therewith. The database is in electronic communication with the microprocessor. The database is populated with single-color image data sets representative of authentic information for the intrinsic portion.
The various embodiments will hereinafter be described in conjunction with the following drawing figures, wherein like numerals denote like elements, and wherein:
The following detailed description is merely exemplary in nature and is not intended to limit the systems and methods for authenticating consumer products as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
Embodiments described in detail below include systems and methods for authenticating consumer products. Consumer products, as referred to herein, are articles of manufacture, natural products, or other articles of commerce that a consumer is desirous of procuring for the product itself. The consumer can be a retail consumer, an industrial consumer, or any other individual or group of individuals that is desirous of learning authenticity of the product at issue. The systems and methods, as described herein, are readily available to consumers, relying upon portable computing devices such as cellphones, personal digital assistants (PDAs) or tablet computers, scanning devices, and the like to effectuate authentication by capturing an image of an intrinsic portion of the consumer product and comparing the image to a stored data set that is representative of authentic information for the intrinsic portion of the consumer product. In particular, filtered light from an intrinsic portion of the consumer product or packaging material associated with the consumer product is detected using a photodetector of the portable computing device to produce at least one single-color image data set representative of the intrinsic portion for at least one color, and the at least one single-color image data set is compared with the stored data set, with an indication of authenticity provided based upon the comparison. The “intrinsic portion” of the consumer product or, alternatively, an “intrinsic portion” of the packaging material associated with the consumer product, as referred to herein, is a portion of the product itself including design elements, material surfaces, artistic patterns, or the like that contribute to design and/or function of product rather than an added feature whose sole purpose is for providing an interrogable indication for authentication. The systems and methods, as described herein, do not rely upon pre-configured security features, with the comparison between the at least one single-color image data set and the stored data set conducted independent of and separate from any analysis of non-color data obtained from preconfigured security features. In this manner, authentication can be conducted by virtue of color analysis of the product or associated packaging itself utilizing the portable computing device without a requirement for specialized devices to enable authentication of complex pre-configured security features.
The systems and methods as described herein generally involve detecting and analyzing filtered light from an intrinsic portion of the consumer product or packaging material that is associated with the consumer products. The “intrinsic portion” of the consumer product or, alternatively, an “intrinsic portion” of the packaging material associated with the consumer product, is a portion of the product itself or packaging including design elements, material surfaces, artistic patterns, or the like that contribute to design and/or function of product rather than an added feature whose sole purpose is for providing an interrogable indication for authentication. The intrinsic portion represents the portion of the product or packaging that is interrogated for authentication purposes and is defined by at least a portion of a viewing area of the photodetector, as described in further detail below. In embodiments, the intrinsic portion is not preconfigured to provide an interrogable indication for authentication, and the intrinsic portion may be free from a preconfigured security feature. Rather, identification of the intrinsic portion as providing an interrogable area for authentication may be conducted in a later step associated with populating a database with authentic information, e.g., based upon observation of the consumer product after design of the consumer product is complete. For example, the consumer product may be analyzed for areas that would be difficult to fraudulently reproduce by a counterfeiter, and those areas may be designated as the intrinsic portion that is subject to interrogation for purposes of rendering authentication determinations.
Referring to
The photodetector 16 is configured to produce single-color image data sets 34 representative of the intrinsic portion 20 of the consumer product 21 or packaging material associated therewith. Production of the single-color image data sets is represented by box 34. For example, the single-color image data sets 34 may be conventionally produced through Bayer filtering, whereby light into the photodetector 16 passes through an array of spectral filters 24, resulting in patterns 26, 28, 30 of individual colors on a square grid of photosensors in the photodetector 16. Conventionally, a mosaic of the patterns 26, 28, 30 forms an RGB image, and pixel data from the photodetector 16 and representative of the RGB image can be stored in the portable computing device 12 or associated storage media. A black/white pattern 32 may also be derived from the respective color patterns 26, 28, 30. However, each pattern 26, 28, 30 can be captured to produce a single-color image data set 34 representative of the respective red, green, and blue color patterns. In embodiments, the single-color image data sets 34 can include pixel location and intensity data for each pixel in the pattern, effectively quantifying the information gathered by each pixel.
When exposed to light emitted by the light source 22 (e.g., light from the LED), the intrinsic portion 20 emits at least some spectral content in the visible wavelength. More specifically, the intrinsic portion 20 has areas of visible “color” that can be resolved by the photodetector 16 of the PDA. In embodiments, the intrinsic portion 20 has a minimum amount of spectral content to enable effective yield of patterns 26, 28, 30 in at least a portion of the viewing area 23 of the photodetector 16. Conversely, the intrinsic portion 20 may have a maximum content of non-spectral content such as, e.g., black lettering or metallic features that would make color comparison difficult. The minimum amount of spectral content may vary depending upon number of pixels of the digital camera, clean area (devoid of other characters or color changes) around the intrinsic portion 20, focus requirements for the digital camera, fast movement that could blur the image, or other factors known to impact image quality. In one embodiment, for a photodetector having a high number of pixels (e.g., >5 MP), then the minimum amount of spectral content may be at least 5% while still enabling effective yield of patterns 26, 28, 30.
The database 18 is in electronic communication with the microprocessor 14, and the database 18 is populated with single-color image data sets 34 that are representative of authentic information for the intrinsic portion 20 of particular consumer products. Methodologies for populating the database 18 are described in further detail below. The database 18 can be maintained in a non-transitive storage medium that is either physically included in the portable computing device 12, or physically separate but in electronic communication with the portable computing device 12.
An exemplary embodiment of a method for authentication of a consumer product 21 will now be described with reference to
In accordance with the exemplary method, the consumer product 21 is provided, optionally with packaging material associated therewith. The consumer product 21 may be provided at various locations including, but not limited to, a retail location, a wholesale location or warehouse, or in public commerce (e.g., during an exchange between consumers). A software application or “app” may be initiated in the portable computing device 12, and information regarding the imaging template data for the intrinsic portion 20 may be retrieved from the database 18 based upon preliminary information 40 for the consumer product 21, represented by box 40 in
The method may proceed with identifying the intrinsic portion 20 of the consumer product 21 within the viewing area 23 of the photodetector 16 using the microprocessor 14 of the portable computing device 12. In an embodiment, upon successful identification of the consumer product 21 to be authenticated within the software application, an imaging template may be generated on the screen of the portable computing device 12, with the imaging template based on the imaging template data obtained from the database 18. The imaging template overlies a viewing area 23 of the photodetector 16 as displayed on the screen of the portable computing device 12 so as to provide an indication to the consumer of the general geometry of features for which to search for the intrinsic portion 20 on the consumer product 21 or packaging thereof. The portable computing device 12 may provide feedback to the consumer to move closer or in particular directions for purposes of isolating and/or optimizing the intrinsic portion 20 of the consumer product 21 in the viewing area 23 of the photodetector 16 based upon the imaging template. For example, the portable computing device 12 may provide feedback for the consumer to move orientations to minimize specular reflection or other image contamination factors. As represented by box 50 in
After identification of the intrinsic portion 20 using the portable computing device 12, and as represented by box 60 in
Once the at least one single-color image data set 34 is produced in box 34, the at least one single-color image data set 34 is compared with a stored data set for the corresponding color that is representative of authentic information for the intrinsic portion 20, as represented in box 70 of
As represented by box 80, an indication of authenticity of the consumer product 21 may then be provided with the portable computing device 12 based upon an outcome of comparing the at least one single-color image data set 34 with the stored data set representative of authentic information for the intrinsic portion 20 (i.e., with authentication decision represented by a “Yes” or “No” from Box 70 in
In embodiments, the portable computing device 12 can be calibrated prior to detecting the filtered light 27 from the intrinsic portion 20 of the consumer product 21. Calibration/normalization techniques may be employed to maximize accuracy of authentication in accordance with the methods described herein. Consistent authentication may require control of illumination and detection parameters in order to optimize image quality, optimize repeatability (e.g., two different devices operate similarly), and allow for similar processing of images captured under different conditions. Variances in illumination/imaging may affect the intended results. For example, the photodetector may be subject to operation under many forms of illumination including direct sunlight, cloudy day scattering, fluorescent light, incandescent light, white light LED, etc. Each of those conditions may have a color temperature associated with it, but it also may not be uniform across the 400-700 nm spectral region. In embodiments, a white area with a known normal sunlight CIE coordinate may be employed to calibrate for the different illumination conditions. Any type of light other than direct sunlight would show a deviation from the normal sunlight CIE coordinate and can be mathematically manipulated back to the normal sunlight case. That manipulation can be added into the remainder of the color field so that correction creates more uniform actionable data. Further, in embodiments, calibration methods may be employed to normalize images to one another and between devices so they can be processed similarly.
In another embodiment of an exemplary method, an imaging template does not already exist in the database 18 for an intrinsic portion 20 of the consumer product 21 at issue. In this embodiment, the consumer product 21 is provided as described above in the context of
In another embodiment and with reference to
While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment. It being understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope as set forth in the appended claims.
