About 60 percent of cosmetic products sold in the dominant Taobao internet shopping mall proved recently to be counterfeit products made in China. This paper is to investigate the anti-counterfeiting strategies to clean up fake goods for Korean cosmetics which have been exported to China. Using the scienter rule the paper classified the forgery action for Korean cosmetics into four broad groups - counterfeit, piracy, illegally distributed product, and brand prior register. This paper suggested interior company's anti-counterfeiting strategies for each group, focusing on the construction for an integrated anti-counterfeiting system including consumer's rationality through the government cooperation between Korea and China.

The purpose of this study is to establish a quality assurance method and managerial standard through management practices and identification method of counterfeit items as measure to eradicate counterfeit items of weapon system. We have performed a study in three significant terms. First, a general study on counterfeit items. In this part, we have described the definition, cause and control need of counterfeit item. Second, management practice of foreign-purchased counterfeit items. Finally, quality assurance methods of counterfeit items. We have proposed the counterfeit items management method, building managerial standard and network, improvement of a system and strengthening quality assurance method.

전자 상거래의 발달로 인해 전자 화폐의 개발 및 연구는 현재 활발하게 진행되어지고 있다. 전자화폐는 고액과 소액의 금액 단위 및 보안 요구 사항으로 위조 방지, 익명성, 분할성, 이중사용 방지 등의 다양한 요구를 만족 시켜야 한다. 이에 본 논문에서는 해쉬체인을 이용한 소액의 은행 전용의 전자화폐에 관하여 연구하였다. 보안 요구 사항으로는 분할성, 위조 방지, 이중사용 방지를 제공해 주고 있다. 기존의 해쉬 체인의 경우 사용자가 발행하여 은행으로부터 정당성을 증명하는 경우가 대부분이나 본 논문에서는 은행이 사용자의 요청으로 인해 해쉬체인을 생성하여 제공한다. 이로 인해 인출 프로토콜의 통신횟수가 줄어들었다.

본 논문에서는 인쇄물의 위조방지를 위해 에러에 강한 디지털 워터마킹을 제안한다. 제안한 알고리즘은 워터마크 삽입을 위해 먼저 원영상을 웨이브릿 변환하여 근사(approximation) 이미지를 얻고, 워터마크는 근사 이미지의 DC계수를 제외한 중요한 DCT계수에 삽입된다. 워터마크의 강건도 향상을 위해 에러정정코드와 반복을 적용하고, 디지털 기기사이의 변환에 의한 차이를 줄이기 위해 CIE Lab 칼라 공간을 사용하였다. 표준 칼라 영상을 사용하여 실험한 결과, 기존 방법에 비하여 적은 반복으로도 비트에러가 발생을 감소하였으며, 알고리즘은 1차의 프린트 스캔에서는 robust 하고 2차의 프린트 스캔에서는 fagile 한 성격을 나타내었다, 본 알고리즘은 여권, 지폐, 신분증, 면허증등과 같은 인쇄물의 위조방지에 이용될 수 있다.

To protect the market for various products, existing authentication techniques using ID, hologram and RFID have been gradually developed. However, these methods can be easily exposed the authentication information, and also these exposed information easily copy. Thus, production of the counterfeit goods can not completely prevent. In this paper, to solve these problems, we designed JCVM file system for saving and managing the authentication information, user's information and a sales agency information into the smart card. And we designed and implemented an authentication protocol that can authenticate to avoiding exposure using processor of the smart card. Through this, this proposed scheme can prevent occurrences of the counterfeit goods. And also, can be used for authentication as any product that can attach the smart card.

Recently, artificial intelligence parking control systems have increased the recognition rate of vehicle license plates using deep learning, but there is a problem that they cannot determine vehicles with fake license plates. Despite these security problems, several institutions have been using the existing system so far. For example, in an experiment using a counterfeit license plate, there are cases of successful entry into major government agencies. This paper proposes an improved system over the existing artificial intelligence parking control system to prevent vehicles with such fake license plates from entering. The proposed method is to use the degree of matching of the front feature points of the vehicle as a passing criterion using the ORB algorithm that extracts information on feature points characterized by an image, just as the existing system uses the matching of vehicle license plates as a passing criterion. In addition, a procedure for checking whether a vehicle exists inside was included in the proposed system to prevent the entry of the same type of vehicle with a fake license plate. As a result of the experiment, it showed the improved performance in identifying vehicles with fake license plates compared to the existing system. These results confirmed that the methods proposed in this paper could be applied to the existing parking control system while taking the flow of the original artificial intelligence parking control system to prevent vehicles with fake license plates from entering.

전자화폐는 기존의 화폐 개념을 네트워크 상으로 옮겨 디지털화한 무형의 화폐 또는 지불수단으로, 기존 신용력에 기반을 두고 종이 화폐가 가지고 있었던 불편함을 해소하기 위해 원격지 이송에 따른 통신기능, 휴대 및 보관관리의 편리성, 위조방지 기능을 기존 화폐 개념기능에 추가한 것이며, 온라인 방식과 오프라인 방식이 있다. 본 논문에서는 오프라인 방식 전자화폐가 만족해야 할 요구사항, 즉, 익명성, 위조불가능성, 이중사용방지와 조건부 익명성 철회를 충족시킬 수 있는 시스템의 구조와 프로토콜을 제시하고, 이를 자바카드를 이용해서 구현하였다.

Recently, a location-based threshold-endorsement(LTE) scheme is proposed to thwart bogus data injection attacks. The scheme exhibits much greater filtering power than earlier symmetric schemes and results in enhanced energy savings. In this paper, we show that LTE has fatal vulnerabilities. We also propose an improved scheme that mitigates the weakness and thereby achieves the original claims without lessening remarkable filtering power intended in LTE.
