This paper presents a hybrid fabrication method for producing anti-counterfeit optical elements on plastic products and surfaces targeting multidiscipline applications such as food, pharmaceuticals, luxury goods, and electronics industry. Our proposition combines the design flexibility and rapid prototyping capabilities of stereolithography three-dimensional (SLA 3D) printing with nanoimprint lithography (NIL) to create unique optical security tags onto plastic surfaces. The proposed approach is cost-effective, scalable, and tailored for mass production, addressing the increasing demand for secure and reliable authentication solutions. NIL is substrate agnostic, offering material selection versatility and realization of security tags onto polymer surfaces, which are widely used across various sectors such as packaging industry, medical devices, and flexible electronics. This enables integration into a wide range of materials, further enhancing applicability on flat and 3D shape surfaces. An evaluation method based on digital reconstruction has been used to ensure robust performance and verification of the produced optical security features. The results demonstrate that this hybrid approach provides a reproducible and technically feasible path for the development of optical anti-counterfeiting tags suitable for large-scale implementation, particularly within fast-moving consumer goods (FMCG).

This research aims to assess consumer attitudes towards purchasing pre-loved luxury fashion items and explore how these attitudes influence their intention to buy such products. Luxury goods consumption is evolving into a multifaceted proposition where customers actively take on new responsibilities. In addition to being purchasers and users, they occasionally turn into luxury brand product dealers. Luxury fashion, which includes more expensive materials, apparel, and frequently new and limited-edition items, is unquestionably stylish. Luxury brands could draw clients and the attention of many audiences, becoming quite prominent, even though luxury fashion only makes up a small portion of the economy compared to other significant businesses. Using a convenience sampling technique, data were collected from 282 individuals in Cairo. The analysis was conducted through SPSS software v2023. Our findings show that consumers’ concerns about the environment have a big influence on their perceived value (PI) of used luxury fashion items, both directly and indirectly through the mediation of their desire for sustainability. Nonetheless, attitude strength has a moderating effect on this association. It is interesting to note that the relationship between environmental concern and sustainability is weakened under the influence of attitude strength. Furthermore, our findings indicate that modest levels of attitude strength make it easy to change how customers’ environmental concerns affect their previously owned luxury fashion items. High-end stores can also fight off counterfeit marketplaces by providing authentication services to consumers of pre-loved luxury clothing. This study emphasizes the role of consumer attitude as a mediator in shaping purchase intentions for pre-loved luxury fashion. However, its focus on one region and cross-sectional data collection presents limitations. Future studies should explore other markets and use longitudinal data for a deeper understanding. This research contributes to the existing literature by offering insights for consumers, marketers, and sellers promoting pre-loved luxury fashion. Full article

Pterocarpus santalinus is considered among the finest luxury woods in the world and has potential commercial and medicinal value. Due to its rich hue and high price, Pterocarpus santalinus has often been substituted and mislabeled with other woods of lower economic value. To maintain the order of the timber market and the interests of consumers, it is necessary to establish a fast and reliable method for Pterocarpus species identification. In this study, wood samples of Pterocarpus santalinus and nine other wood samples commonly used for counterfeiting were analyzed by visible light/near-infrared (Vis/NIR) hyperspectral imaging (HSI). The spectral data were preprocessed with different algorithms. Principal component analysis (PCA) was applied in different spectral ranges: 400~2500 nm, 400~800 nm, and 800~2500 nm. Partial least squares discriminant analysis (PLS-DA) and square support vector machine (SVM) modeling methods were performed for effective discrimination. The best classification model was SVM combined with a normalization preprocessing method in whole spectral range (400~2500 nm), with prediction accuracy higher than 99.8%. The results suggest that the use of Vis/NIR-HSI in combination with chemometric approaches can be used as an effective tool for the discrimination of Pterocarpus santalinus. Full article

Counterfeiting is an important challenge in maintaining the security and sustainability of supply chains. This paper examines a supply chain consisting of a luxury goods manufacturer (and a retailer) in the presence of counterfeit goods. Inspired by the reality that both manufacturers and retailers have incentives to implement anti-counterfeiting, this paper combines the psychological impact of anti-counterfeiting efforts on consumers and discusses the impact of anti-counterfeiting efforts on pricing and profits. We find that: (1) anti-counterfeiting has a positive impact on the selling price of brand products and the firms’ profits. However, the impact on wholesale prices varies depending on who implements the anti-counterfeiting strategy. (2) Only when the quality of brand products is higher than the threshold, is the firm willing to input anti-counterfeiting efforts. Manufacturers in a reselling structure are more motivated to fight counterfeits. (3) Implementing anti-counterfeiting in a direct selling structure is the most effective strategy for manufacturers. Under a reselling structure, it is more beneficial for manufacturers to have the retailer input anti-counterfeiting efforts. Our study provides insights into the reasons why some manufacturers establish internal anti-counterfeiting teams under the direct selling structure, while others incentivize retailers to invest in anti-counterfeiting.

High-quality luxury products cater to a specific group of consumers due to their durability and the value attached to them. Counterfeiting luxury products has resulted in economic losses for both the producers and consumers. The market for counterfeit luxury products has continued to grow due to the difficulty in authenticating genuine luxury products. The traditional system of verification largely depends on the expert use of specialized equipment for visually inspecting physical luxury products and their associated certificates. This conventional process of authenticating luxury products is expensive, slow, and not easily accessible to consumers. Hence, there is a need for a digital verification approach for luxury products. Blockchain provides the potential for providing traceable and immutable information about a given luxury product. The focus of this paper is to develop a blockchain decentralized application (DApp) for authenticating luxury products in the class of luxury accessories such as jewelry across their respective lifecycles. To achieve this, qualitative analytics is applied to identify useful features for the digital authentication of luxury products. Blockchain requirement engineering modelling is then applied to explore the use of blockchain technologies to realize the features that guarantee transparency in the ownership and use of luxury products. Furthermore, this paper explores the existing blockchain technologies for realizing and implementing the developed requirements of the authentication DApp for luxury products. The selected blockchain technology stack is applied in prototyping authentication systems for luxury products. The implemented platform is simulated to demonstrate the operations carried out in authenticating luxury products. Full article

The marking and surface structuring of various materials is important in various industrial fields such as biomaterials, luxury goods, anti-counterfeiting, automotive and aerospace, electronics and semiconductor industries, and others. Recent advances in laser technology, such as burst-mode lasers, have opened new ways of affecting the surfaces of various materials, inducing a different appearance and/or properties of the laser-exposed areas. From earlier studies, it is known that when splitting a single pulse into multiple pulses and thus creating a quasi-MHz–GHz repetition rate regime, it is possible to increase not only the ablation efficiency but it also provides the possibility to tune the heat in-flow into the surface. Such new regimes enable the control of the surface roughness as well as the optical properties and corrosion resistance. In this work, we analyze the effect of the different burst-mode regimes for the marking of stainless-steel samples, aiming to produce high-contrast marking having different shades of black/white color (black-gray-white). Moreover, we investigate the angular dependence of the reflected light after laser treatment numerically from the measured surface morphology Full article

In recent years, counterfeit luxury products have become a major concern for consumers worldwide. The reason for the proliferation of counterfeit products is that the manufacturing and distribution process is not transparent to consumers and this information can be easily falsified or altered by others. To solve this problem, this paper proposes the development of a management system using blockchain and smart contract technology to solve the problems of data forgery and data tampering, while tracking the information related to luxury products and ensuring the accuracy and authenticity of the relevant data, to achieve the purpose of luxury product anti-counterfeiting. When using Hyperledger Fabric to deploy the blockchain and execute smart contracts, all information related to the production and logistics process of luxury goods will be uploaded to the blockchain. No human intervention is required to create a complete, traceable, tamper-proof, and trusted repository. Compared to previous work, this paper combines blockchain technology with specific processes in the supply chain, employing a variety of security methods to secure the communication process. Moreover, our proposed solution is more flexible in transmission, with more secure protocols also making data harder to tamper with and falsify, thereby solving the problem of forgery and tracking of luxury products.

Global sales of second-hand luxury products are steadily increasing. To better understand key drivers for purchasing second-hand luxury products, a survey was conducted including 469 respondents. The study not only includes existing customers, but also non-customers and thus potential future clientele. Based on the theory of planned behavior, the components of attitude, subjective norms, perceived behavioral control, and individual motivators (creative, economic, ethical, nostalgic, sustainable) were investigated. Using structural equation modeling, the results support the influence of attitude, past purchase experience, perceived behavioral control, and subjective norms on purchase intention. Attitude, in turn, is mainly impacted by economics and ethics as individual motivators. Further, subjects were asked to state their own definition of luxury and to name individual reasons for and against second-hand luxury products. Thereby, quality turned out to be double-edged: on the one hand, second-hand products were able to prove their quality, on the other hand, the fear of counterfeits and unhygienic products was cited. Overall, consumers of second-hand luxury goods are heterogeneous and have different buying experiences with one or more of the three categories: new luxury goods, second-hand luxury goods, and second-hand products. The study thus expands the understanding of the transformation within the (second-hand) luxury industry. Full article

Counterfeiting is found today in many industries and in various forms with severe consequences for supply chain operations. Products counterfeiting can be detected in consumer goods such as clothing, food and beverages, accessories, pharmaceuticals, electronics, and luxury goods. The continuous violations in the supply chain have led to the need for mobilization of all involved stakeholders to overcome counterfeiting challenges. Effective traceability seems to be the only way to combat this phenomenon, ensuring safe and sustainable supply chain operations. This paper presents a structured literature review on traceability approaches for combatting the product supply chain counterfeiting phenomenon that led to forming a structured classification framework. The performed analysis aims to identify trends and good practices and can be used as a guideline for real-life projects against supply chain counterfeiting. The results show that traditional traceability methods are not effective as they can be easily falsified using today’s technological advancements. However, these same advancements also present valuable technologies such as blockchain and the internet of things to ensure safe and sustainable supply chain operations. Full article

Existing product anti-counterfeiting and traceability solutions across today’s internationally spanning supply chain networks are indeed developed and implemented with centralized system architecture relying on centralized authorities or intermediaries. Vulnerabilities of centralized product anti-counterfeiting solutions could possibly lead to system failure or susceptibility of malicious modifications performed on product records or various potential attacks to the system components by dishonest participant nodes traversing along the supply chain. Blockchain technology has progressed from simply being a use case of immutable ledger for cryptocurrency transactions, to a programmable interactive environment of developing decentralized and reliable applications addressing different use cases globally. Key areas of decentralization, fundamental system requirements, and feasible mechanisms of developing decentralized product anti-counterfeiting and traceability ecosystems utilizing blockchain technology are identified in this research, via a series of security analyses performed against solutions currently implemented in supply chain industry with centralized architecture. The decentralized solution will be a secure and immutable scientific data provenance tracking and management platform where provenance records, providing compelling properties on data integrity of luxurious goods, are recorded and verified automatically across the supply chain.

An interesting research problem in the supply chain industry is evaluating and determining the provenance of physical goods—demonstrating the authenticity of luxury goods such as bottled wine. However, many supply chain systems and networks have been built and implemented with centralized system architecture, relying on centralized authorities or any form of intermediary, and leading to issues such as single-point processing, storage and failure, which could be susceptible to malicious modifications to product records or various potential attacks to system components by dishonest participant nodes traversing along the supply chain. Blockchain technology has evolved from merely being a decentralized, distributed and immutable ledger of cryptocurrency transactions to a programmable interactive environment for building decentralized and reliable applications addressing different use-cases and existing problems in the world. In this research, with a chosen research method of proof-by-demonstration, the Decentralized NFC-Enabled Anti-Counterfeiting System (dNAS) is proposed and developed, decentralizing a legacy anti-counterfeiting system of the supply-chain industry using Blockchain technology to facilitate trustworthy data provenance retrieval, verification and management, as well as strengthening the capability of the product’s anti-counterfeiting and traceability qualities in the wine industry, with the capacity to further extend this to the supply chain industry as a whole. The proposed dNAS utilizes a decentralized blockchain network with a consensus protocol compatible with the concept of enterprise blockchain, programmable smart contracts and a distributed file storage system to develop a secure and immutable scientific-data provenance tracking and management platform on which provenance records, providing compelling properties of the data integrity of luxurious goods, are recorded, verified and validated automatically.

The proliferation of counterfeit luxury goods poses a great threat to the sustainable development of the luxury goods industry; it also disturbs the order of economic development, causes the aggravation of environmental pollution, and is contrary to the principle of global sustainable development. How to effectively weaken consumers’ willingness to buy counterfeit luxury products has become a focal issue. This research explores the impact of value consciousness, social risk perception, and face consciousness on the purchase intention of counterfeit luxury. In addition, this study explores the different mediating roles played by attitude. The results show that value consciousness has a significant positive impact on the counterfeit luxury purchase intention through the full mediation of attitudes. Perceived social risk not only exerts a direct negative impact on the purchase intention of counterfeit luxury products but can also indirectly influence intention through the partial mediation of attitudes. Besides, there is an inverted U-shaped relationship between face consciousness and counterfeit luxury purchase intention, and attitudes play a partially mediating role in this inverted U-shaped path. This research also has certain management implications for the government and luxury products companies to formulate relevant policies and marketing strategies to curb consumers’ willingness to purchase counterfeit luxury products.
