Description

SYSTEM AND METHOD FOR MULTI-LEVEL PRODUCT AUTHENTICATION BACKGROUNDTechnical Field

[0001] The embodiments herein generally relate authentication systems or digital authentication systems, more particularly related to a system and a method for multi-tier product authentication and destructive tamper-detection of a product.Description of the Related Art

[0002] Product counterfeiting and unauthorized duplication of packaged goods has become a significant challenge across various industries including pharmaceuticals, consumer goods, electronics, and supply chain logistics. Many existing products rely on conventional authentication mechanisms such as printed labels, barcodes, or QR codes to verify authenticity. However, these identifiers can be easily copied, photographed, or reproduced, allowing counterfeit products to enter the market while appearing legitimate. Such practices reduce consumer trust and create difficulties in verifying the originality of products.

[0003] Advancements in digital verification technologies have enabled the use of machine-scannable codes and database-based validation systems for product authentication. These systems typically involve scanning a code using a user device and verifying the scanned information with a server or database. While these approaches improve traceability and tracking of products across supply chains, many of these systems rely on static codes that can be duplicated or reused across counterfeit items, thereby reducing the effectiveness of authentication.

[0004] Existing authentication systems that utilize a single machine-scannable code for verification often lack mechanisms to ensure that the code originates from an original physical package. In such systems, a copied image of the code may still be scanned and validated successfully. As a result, counterfeiters may replicate the authentication code and distribute duplicate products that pass verification checks, thereby compromising product integrity and security.

[0005] Certain packaging -based security solutions attempt to incorporate tamper-evident labels or seals to indicate whether a package has been opened. Although these mechanisms provide a basic level of tamper indication, many of them can still be removed and reattached or replaced without clear detection. Consequently, these systems fail to reliably detect tampering or unauthorized reuse of authentication labels across different products.

[0006] Furthermore, existing authentication systems typically perform only a single-stage verification process, which may not be sufficient to confirm both product authenticity and package integrity. The absence of multi-tier authentication mechanisms that combine physical uniqueness, digital verification, and tamper detection limits the reliability of current solutions in preventing counterfeiting and unauthorized product substitution.

[0007] Shrinks are well known solutions but have several limitations. Shrinks need further enhancement to address fraudulent leaks in current reward solutions which involves consumer-authentication and credible loyalty. Existing solution is to print loyalty QR code on WAD inside cap and cap seal needs to be broken to reveal the QR code. But printing the QR codes remain exposed and those can be misused, to claim rewards later when codes are activated. Even if rewards are allowed to be claimed from registered mobile number still can be misused from registered mobiles.

[0008] Further, sometimes the rewards can be ignored in fake packaging. Once capseal is broken to reveal QR code on WAD, the same QR code can be used within fake packaging by ignoring loyalty claim on rewards. So, the existing inventions deficient in 2-fold i.e. QR codes leakage upstream in supply chain during print or filling-line, and even though the QR code on WAD remains hidden but WAD is not destructible and can be reused within fake packaging thereby ignoring loyalty-scan in requirement of rewards.

[0009] Accordingly, there remains a need for a system and method to address the aforementioned technical drawbacks.SUMMARY OF THE INVENTION

[0044] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Referring now to the drawings and more particularly to FIGS. 1 through 15, where similar reference characters denote corresponding features consistently throughout the figure’s, preferred embodiments are shown.

[0045] FIG. 1 illustrates a system view for multi-tier product authentication and destructive tamper-detection of a package 112 according to some embodiments herein. The system view includes a system 100 including the package 112, a shrinkable band 114, a user device 102, a network 104, and an authentication server 106. The package 112 is configured to hold or store a product. In some embodiments, the package 112 is selected from any of: a container, an enclosure, a box, a bottle, and the like. For example, the package 112 can be a carton box, a shipping box, a parcel used for shipments, a cylindrical container, an electronics packaging box, a lab specimen box, a transport case, and the like. The package 112 may be made of a paperboard, plastic, polymer, composite material or metal. In some embodiments, the product is selected from any of: consumer goods, pharmaceutical products, medical samples, high-value electronics, laboratory materials, defence equipment, logistics packages, industrial components, or luxury goods.

[0046] The shrinkable band 114 is configured to dispose on the package 112. In someembodiments, the shrinkable band 114 encircles or fits the package 112, to secure the package 112. The shrinkable band 114 may be a heat-shrinkable band. In some embodiments, the shrinkable band 114 is made of a heat-shrinkable polymeric material. The heat-shrinkable polymeric material may be any of, but not limited to, PVC, PET, PLA or multi-layer shrink films. Upon using at least one source, the shrinkable band 114 contracts either radially and longitudinally or both to tightly conforming to an outer surface of the package 112, thereby locking the package 112 in a closed state. The at least one source may be a heat source, where the heat is applied using a hot air source, a dryer, or other thermal devices. The shrinkable band 114 acts as a security element that enables both authentication and tamper detection.

[0047] The shrinkable band 114 includes an externally visible layer and an internal layer arranged such that the internal layer remains concealed by the externally visible layer. The externally visible layer includes a first machine-scannable code and a first non-clonable copy -proof artefact. The first machine-scannable code may be a QR code, a barcode, a matrix code, or a graphic identifier. The non-clonable copy-proof artefact may be a physically unique structure material, a textured pattern material, or other physically unpredictable structure, which cannot be precisely replicated, duplicated, cloned or reproduced. In some embodiments, the first machine-scannable code and the non-clonable copy -proof artefact are associated with the package. The internal layer includes a second machine-scannable code and a second non-clonable copy -proof artefact which remains hidden beneath the externally visible layer until the shrinkable band is physically disturbed or removed. The second machine-scannable code may be a QR code, a barcode, a matrix code, or a graphic identifier.

[0048] The second machine-scannable code and the second non-clonable copy -proof artefact in the inner layer is associated with the first machine-scannable code and the first non-clonable copy-proof artefact, by capturing and registering characteristic features of a digital signature associated with the first machine-scannable code, and a predefined digital association between the externally visible layer and the internal layer, in the authentication server 106. In some embodiments, the user device 102 is configured to capture and register the characteristic features. The user device 102 may be, but not limited to, a tablet, a laptop, a computer device, a customized input device, or a mobile phone for capturing any of imaging data, visual data or encoded data. The user device 102 may utilize an imaging sensor, a camera module, or an optical scanner to capture required data. The user device 102 uses the network 104 to communicate with the authentication server 106. In some embodiments, the network 104 can be a wired network, a wireless network, or a combination of the wired network andthe wireless network. In some embodiments, the network 104 is an Internet.

[0049] The authentication server 106 includes a memory 108 and a processor 110. The memory 108 is configured to store a set of instructions for executing the processor 110, the characteristic features of the digital signature associated with the first machine-scannable code, and the predefined digital association between the externally visible layer and the internal layer, associated with the package 112. In a packaging process of the package 112, the shrinkable band 114 is positioned around the package 112 at any position to cover the externally visible layer and the internal layer of the shrinkable band 114. Upon using the at least one source, the shrinkable band 114 contracts, and the externally visible layer and the internal layer becomes sandwiched between the shrinkable band 114 and an outer surface of the package 112.

[0050] When a user receives the package 112, the user may be enabled to capture the first machine-scannable code and the first non-clonable copy-proof artefact using the user device 102. The user device 102 captures first scan data including images of the externally visible layer including the first machine-scannable code and the first non-clonable copy-proof artefact of the shrinkable band 106, of the package 112. The first scan data is transmitted to the authentication server 106 through the network 104.

[0051] The authentication server 106 is configured to receive the first scan data including the images of the first machine-scannable code and the first non-clonable copyproof artefact, of the package 112 and initiates an authentication process. The authentication server 106 is configured to extract characteristic features associated with a physical structure of the first machine-scannable code and the first non-clonable copy-proof artefact, from the first scan data. The characteristic features may include texture patterns, edge features, spatial distribution of structures, pixel-level variations, or micro-pattern signatures present in the non-clonable copy-proof artefact, and a placement of the non-clonable copy -proof artefact and the first machine-scannable code. The authentication server 106 is configured to compare the extracted characteristic features with the stored digital signature associated with the externally visible layer stored in the memory 108 of the authentication server 106. Based on the comparison between the extracted characteristic features and the stored digital signature, the authentication server 106 validates authenticity of the first non-clonable copy -proof artefact. If the extracted characteristic features match, the authentication server 106 may request for second scan data. If the extracted characteristic features do not match, the authentication server 106 may determine that the package 112 as potentially counterfeit or unregistered.

[0052] When the second scan data is requested, the user is enabled to perform destructive removal of at least a portion of the externally visible layer of the shrinkable band 114 to view the second machine-scannable code and the second non-clonable copy-proof artefact in the inner layer of the shrinkable band 114. In some embodiments, the at least a portion of the externally visible layer of the shrinkable band 114 is configured to tear, or disturb to expose the second machine-scannable code and the second non-clonable copy-proof artefact located on the internal layer, ensuring that the second machine-scannable code and the second non-clonable copy-proof artefact can only be accessed after physical interaction with the shrinkable band 114, thereby preventing unauthorized reuse of. After the second machine-scannable code and the second non-clonable copy-proof artefact becomes visible, the user can be enabled to capture the second scan data including images of the second machine-scannable code and the second non-clonable copy-proof artefact using the user device 102. The second scan data is transmitted to the authentication server 106 through the network 104.

[0053] The authentication server 106 is configured to receive the second scan data including images of the second machine-scannable code and the second non-clonable copyproof artefact from the user device 102. The authentication server 106 is configured to verify the predefined digital association between the externally visible layer and the internal layer stored in the memory 108 upon receiving the second scan data, to confirm a legitimate authentication sequence and generate an authentication result. In some embodiments, the predefined digital association includes any of: a cryptographic relationship, an encoded mapping, or a registered pairing created during the packaging process of the package 112. The authentication result may indicate that the package is authentic, tampered, previously verified, suspected to be counterfeit, and the like. The authentication result is transmitted to the user device 102 and displayed to the user through an application user interface. In some embodiments, the authentication server 106 enables the processor 110 to execute the processes as described above. Once both the externally visible layer and the internal layer is authenticated, loyalty points, or reward points may be rewarded or offered, as per the application.

[0054] FIG. 2 illustrates an exploded view of the authentication server 106 of FIG. 1 according to some embodiments herein. The authentication server 106 includes a database 200, a data receiving module 202, a processing module 204, a feature extraction module 206, a signature matching module 208, a verification module 210, an authentication decisionmodule 212, and an output module 214. The data receiving module 202 is configured to receive scan data from the user device 102 through the network 104. In some embodiments, the scan data includes the first scan data including images of the first machine-scannable code, and the non-cloneable copy-proof artefact disposed on the externally visible layer of the shrinkable band 114, and the second scan data including images of the second machine-scannable code and the second non-clonable copy-proof artefact revealed after destructive removal of the externally visible layer.

[0055] The processing module 204 is configured to preprocess the received scan data prior to authentication. The feature extraction module 206 is configured to extract characteristic features from the images of the non-clonable copy-proof artefact. In some embodiments, the characteristic features include texture patterns, micro-structure patterns, spatial variations, or other unique visual attributes that are difficult to replicate. The signature matching module 208 is configured to compare the extracted feature representation with the stored digital signature associated with the first machine-scannable code. In some embodiments, the signature matching module 208 determines a score between the captured artefact features and the stored reference signature to determine whether the non-clonable copy -proof artefact is authentic. The verification module 210 is configured to verify a predefined digital association between the first machine-scannable code disposed on the externally visible layer and the second machine-scannable code disposed on the internal layer of the shrinkable band 114. In some embodiments, the verification module 210 ensures that the revealed second machine-scannable code corresponds to the first machine-scannable code, thereby confirming a legitimate authentication sequence.

[0056] The authentication decision module 212 is configured to generate an authentication result based on outputs from the signature matching module 208 and the verification module 210. In some embodiments, the authentication decision module 212 determines whether the product is authentic, potentially tampered, or invalid based on predefined validation rules stored in the database 200. The output module 214 is configured to transmit the authentication result to the user device 102 through the network 104. In some embodiments, the output module 214 provides an authentication status, tamper detection notification, or additional product verification information to the user. The output module 214 may further update the database 200 with a record of the authentication event for traceability and monitoring purposes.
