Counterfeit products have been a major concern in global market. With the emergence of RFID systems, to detect counterfeit products in supply chain is relatively easy. Many anti-counterfeiting techniques for products attached by RFID tag are proposed. Most of the previous anti-counterfeiting techniques are not considering the distribution of the counterfeit from a customer to a customer. Using the ownership transfer protocols we can prevent the counterfeit from being distributed on the supply chain as well as between the customers and the customers. The ownership transfer protocols must be modified for anti-counterfeiting because of the usage of the protocol. In this paper, we modify the ownership transfer protocol proposed by G. Kapoor and S. Piramuthu[1] to be able to detect the counterfeit and track and trace the products in the supply chain. Our proposed protocol consists of three phases: the products delivery phase, the products takeover phase, and the products sale phase. We show that our protocol is anti-counterfeiting as well as secure against the security attacks.

The purpose of this study was to analyze anti-counterfeiting strategies of fashion firms in Korea. Data was collected by in-depth interviews for 25 fashion firms and 5 buying offices who had been victims of counterfeiting. The result showed that fashion firms recognized the counterfeiting, especially deceptive counterfeiting, as a serious problem in Korea and seek for stronger protection. Fashion firms adopted diverse strategies for the protection of trademark and for the protection of design； (1) Investigation and Surveillance, (2) Warning, (3) Prosecution, (4) Lawsuit, (5) Consumer education (6) High-tech tabooing, (7) Provide incentives, (8) Penalty, (9) Do nothing. Despite the diverse efforts, they proposed the most desirable strategies to deter the counterfeiting as the changes of consumer attitude and stronger legal protection.

우리의 화장품산업은 향후 수출주도산업으로 중점 육성하는 새로운 성장산업이다. 수출 제1위 시장인 중국에서 한국 화장품은 세계화장품 1위국인 프랑스 제품과 자웅을 겨루고 있을 정도로 좋은 호응을 얻고 있다. 그런데 화장품 역시 여느 산업과 마찬가지로 중국에서 중국의 위조상품으로 큰 피해를 입고 있어, 한국 화장품의 위조상품 근절을 위한 통합적 위조방지 system 구축과 위조형태별로 위조 방지 전략을 강구하였다. 우선 위조의 개념과 위조 형태분석을 통하여 중국에서 한국 화장품의 위조형태를 위조상품, 모조상품, 불법유통상품 그리고 상표의 무단선점으로 구분하였다. 위조행위를 근절시키기 위해서는 우선 기업 내부적으로는 최고경영층의 확고한 위조행위 근절의지에서부터 제품개발, 생산, 판매의 각 단계별로 위조 방지체제를 구축하여야 한다. 기업 외부적으로는 IP-desk와 같은 위조방지지원체제는 물론 한 중 정부간의 협력체제를 총동원하여 위조행위를 근절시켜야 한다. 더욱 중요한 것은 소비자들 스스로가 위조/모조상품을 구매하지 않는 성숙된 소비문화가 정착되어야 할 것이다. 위조상품에 대한 구체적 방지 전략은 기업내부의 사전적 대응으로 hidden tag나 Rfid tag의 부착, 수출통관인증제의 활용과 유통채널의 철저한 감독이 필요하며, 사후적 대책으로 중국정부에 상표법위반에 의한 강력한 단속을 요청하여야 한다. 모조상품에 대한 방지 전략은 모조상표는 상표법위반으로 모조디자인은 중국전리법 위반으로 대처하여야 하며, 소비자에게 정품인식을 위한 홍보도 강화하여야 한다. 불법유통상품들은 샘플판매, 유통기한경과상품의 판매, 밀수상품의 유통들로써 강력한 dealership을 구축하여 이를 적극적으로 저지시켜야 한다. 상표의 무단선점은 상표 및 디자인 등록, 세관등록의 철저를 통하여 예방하여야 한다.

The market for counterfeit luxury fashion goods is proliferating across the globe. In an effort to provide some insight into this phenomenon, this study aimed to identify the antecedents of attitudes toward counterfeits of luxury fashion goods. As antecedents, counterfeit proneness and attitudes toward counterfeiting were considered. It was hypothesized that counterfeit proneness not only influences attitudes toward counterfeits of luxury fashion goods directly but also indirectly through attitudes toward counterfeiting. Data were gathered by surveying university students in Seoul, using convenience sampling. Three hundred five questionnaires were used in the statistical analysis. SPSS was used for exploratory factor analysis, and AMOS was used for confirmatory factor analysis and path analysis. The results showed that all the fit statistics for the variable measures were quite acceptable. In addition, the overall fits of the hypothesized model suggest that the model fits the data well. Factor analysis revealed that counterfeit proneness and attitudes toward counterfeits of luxury fashion goods were uni-dimensional and that attitudes toward counterfeiting were two dimensional, which are 'normatively less susceptible' and 'value conscious'. Test of the hypothesized path showed that counterfeit proneness influences attitudes toward counterfeits of luxury fashion goods indirectly through the two factors of attitudes toward counterfeiting. The results suggest some implications for anti-counterfeit businesses.

This study explores U.S. consumers' perceptions about fashion counterfeit goods and counter feiting and motivations for purchasing and not purchasing those goods. A qualitative research technique utilizing self-administered essay questions was used to collect data. A convenience sample of female college students(N=128) drawn from classes at Midwestern and Southern universities in the U.S. participated in this study. This study found that a majority of consumers tended to perceive that fashion counterfeit goods are merely imitations of the legitimate goods and that counterfeiting is producing and selling fake goods, but a small number of consumers associated those goods with illegally produced goods and illegal practices or violations of intellectual property rights. The major motivations for purchasing counterfeit fashion goods were found to be price/value consciousness, appearance of counterfeit goods, status consumption, availability of the goods, desire for souvenirs, and social(family and peer) influences. In addition, the major deterrents to purchasing these goods were identified as integrity/ethical judgment, poor quality of counterfeit goods, self-image/status, and unavailability of the goods. This study provides policy makers and anti-counterfeit coalitions with information to develop effective educational programs or campaigns to influence consumers' counterfeit fashion purchasing behavior.

Chen 등은 위조 방지와 프라이버시 보호를 위한 RFID 인증 프로토콜을 제안하였다. 제안된 스킴은 저비용의 RFID 태그 보안을 위하여 XOR 연산과 시프트(shift) 연산을 이용하였다. 그러나, 실제적인 응용 환경을 고려하지 않았기 때문에 보안상의 문제점을 비롯하여 몇 가지 취약점을 보인다. 본 논문에서는 Chen 등의 프로토콜을 분석하고 취약점에 대한 의견을 제시한다. 또한, 기존의 스킴을 보완한 RFID 양방향 인증 프로토콜과 효율적인 공급망 관리를 위한 갱신 프로토콜을 제안한다. 제안된 프로토콜은 기존의 XOR 연산 기반의 RFID 인증 프로토콜과 안전성 및 효율성면에서 비교, 분석하였으며, 높은 안전성과 적은 통신 비용이 요구됨을 확인하였다.

$Gd_2O_3:Eu/Bi$ nanoparticles were synthesized via spray pyrolysis and applied for the preparation of a luminescent pearl pigment as an anti-counterfeiting material. The luminescence properties were optimized by changing the $Eu^{3+}$ and $Bi^{3+}$ concentration. Ethylene glycol was used as an organic additive to prepare the $Gd_2O_3:Eu/Bi$ nanoparticles. The highest emission intensity was achieved when the total dopant content was 10.0 at.% and the mole fraction of Bi was 0.1. The concentration quenching was mainly due to dipole-dipole interactions between the same activators, and the critical distances were 9.0 and $19.6{\AA}$ for $Eu^{3+}$ and $Bi^{3+}$, respectively. The prepared $Gd_2O_3:Eu/Bi$ powder exhibited an average size of approximately 82.5 nm and a narrow size distribution. Finally, the $Gd_2O_3:Eu/Bi$ nanophosphor coated on the surface of the pearl pigment was confirmed to have good red emission under irradiation from a portable ultraviolet light-emitting diode lamp (365 nm).

A series of phosphors, SrWO₄:5 mol% Dy³⁺, SrWO₄:5 mol% Sm³⁺, and SrWO₄:5 mol% Dy³⁺:x Sm³⁺ (x＝1~15 mol%), were prepared using a facile co-precipitation. The crystal structure, morphology, photoluminescence properties, and application in anti-counterfeiting fields were investigated. The crystalline structures of the prepared phosphors were found to be tetragonal systems with the dominant peak occurring at the (112) plane. The excitation spectra of the Dy³⁺ singly-doped SrWO₄ phosphors were composed of an intense charge-transfer band centered at 246 nm in the range of 210~270 nm and two weak peaks at 351 nm and 387 nm due to the ⁶H_15/2→⁶P_7/2 and ⁶H_15/2→⁴I_13/2 transitions of Dy³⁺ ions, respectively. The wavelength of 246 nm was optimum for exciting the luminescence of Dy³⁺ and Sm³⁺ co-doped SrWO₄ phosphors. The emission spectra consisted of two intense blue and yellow emission bands at 480 nm and 573 nm corresponding to the ⁴F_9/2→⁶H_15/2 and ⁴F_9/2→⁶H_13/2 transitions of Dy³⁺, and two strong emission peaks at 599 nm and 643 nm originating from the ⁴G_5/2→⁶H_7/2 and ⁴G_5/2→⁶H_9/2 transitions of Sm³⁺, respectively. As the concentration of Sm³⁺ ions increased, the emission intensities of Dy³⁺ rapidly decreased, while the emission intensities of Sm³⁺ gradually increased. These results suggest that the color of the emission light can be tuned from yellow to white by changing the concentration of Sm³⁺ ions at a fixed 5 mol% Dy³⁺. Furthermore, the fluorescent security inks were synthesized for use in anti-counterfeiting applications.

일반적으로 인쇄 문서의 위변조를 방지하기위해 복사방지마크와 이차원 바코드가 많이 사용되고 있다. 하지만 이차원 바코드는 복사 방지 마크와 분리 배치되어 있어 사본 구별이 시각적으로 힘들고, 스캐너로만 인식할 수 있다는 단점이 있다. 따라서 본 논문은 이차원 바코드에 워터마크를 삽입해 시각뿐만 아니라 스캐너로 정확하게 구분 할 수 있는 위변조방지기술에 대해 연구했다. 복사 방지마크는 디지털 입출력 장치의 저주파 필터 특성으로 인해 특정 패턴이 소실되거나 변형되는 것을 이용해 패턴으로 만들었다. 원본과 사본을 스캔한 이미지의 히스토그램을 분석을 통해 성능검증을 했다. 그리고 이차원 바코드를 웹캠이나 핸드폰 카메라로 인식한 인증키로 온라인 서버에 접속해 내용을 확인하는 시스템을 제안했다.
