This study was to investigated why consumers buy counterfeit luxury goods, and to address questions about what was used. To this end, benefits consumers experience using counterfeit or what is profit? In addition, experience using counterfeit what is lost or dissatisfied? Based on the results of previous studies on the use counterfeit motivation, loss of use, benefits, and behavioral factors associated with motivation to learn using these counterfeit goods, benefits, and loss factor, each counterfeit product attitude and purchase intention was affects. First, the motivation for using counterfeit display, economics, satisfaction, usefulness, respectively. Counterfeiting in the attitude demonstrated motivation and quality had a significant impact. The economics of buying a counterfeit, satisfaction and quality significantly affected the motivation. Second, counterfeit benefits and economic benefits, personal benefits factor, respectively. Counterfeit goods on the attitude factor has significant effect personal benefit. Purchase of counterfeit goods, the economic and personal benefits also had a significant impact. Third, the loss factor counterfeit personal loss, quality loss, material loss, and social factors were lost. Attitude toward counterfeits were no significant factors that affect. The social cost of buying a factor had a significant impact. These findings on the behavior of consumers with counterfeit deep understanding helps. In addition, to reduce the future use of counterfeit campaign gives data that can be exploited.

The methods for detecting copy move frogery (CMF) are divided into two categories, block-based methods and keypoint-based methods. Block-based methods have a high computational cost because a large number of blocks should be examined for CMF detection. In addition, the forgery detection may fail if a tampered region undergoes geometric transformation. On the contrary, keypoint-based methods can overcome the disadvantages of the block-based approach, but it can not detect a tampered region if the CMF forgery occurs in the low entropy region of the image. Therefore, in this paper, we propose a method to detect CMF forgery in all areas of image by combining keypoint-based and block-based methods. The proposed method first performs keypoint-based CMF detection on the entire image. Then, the areas for which the forgery check is not performed are selected and the block-based CMF detection is performed for them. Therefore, the proposed CMF detection method makes it possible to detect CMF forgery occurring in all areas of the image. Experimental results show that the proposed method achieves better forgery detection performance than conventional methods.

The present paper attempts to account for customers' purchase intention of counterfeit goods. Based on some previous analyses, we have set up a structured model for analysis with a hope to identify the relationship between benefits from using counterfeit goods and motivational factors to purchase them. It is found, first of all, that motivation for ostentation significantly influences personal benefits from using the counterfeit goods. Second, we also find that motivation for satisfaction does not exert any direct influence on the factors of benefits, though it affects decisions to purchase. Third, motivation for practicability has significant influence on personal and, more strongly, on economic benefits. Fourth, quality has significant influence on both personal and economic benefits. Again, this factor is also more closely related with economic benefits than with personal ones. We hope that we will be able to provide practical tips for those who design and plan public service advertisements that intend to reduce purchasing of counterfeit products.

This study started why do consumers use the counterfeit goods. We executed the pretest through the depth interview, and made an purchase motivation scale, useful satisfaction and dissatisfaction factor scale of counterfeit goods. We found out having the recognition difference of China consumers about these. The results is as follows. First, Counterfeit use motivation ostentation, economic efficiency, satisfaction, and the practicality of four was All counterfeit motivation had a significant impact on attitudes. Second, the personal satisfaction and economic satisfaction as two counterfeit satisfaction factors were Counterfeit products personal satisfaction factors showed a significant influence on the attitude. Also the purchase of counterfeit economic satisfaction had a significant positive impact. Third, counterfeit dissatisfaction factors were personal, social and material factors of dissatisfaction into three Significant influence attitude toward counterfeit products is a factor. Purchase of personal dissatisfaction factors also had a significant impact. These findings made it possible for in-depth understanding of the behavior and culture in China of counterfeit consumer use. The results of this study has provided data that can be utilized in the future counterfeits reduce the use of public awareness campaigns.

오늘날 대부분의 인증 시스템들은 PKI 환경으로 변화하는 추세이며, 인증서의 역할은 날로 중요해지고 있다. 만일 이런 인증서가 위조 된다면 심각한 정보 사고가 발생할 것이다. 따라서 인증서는 위조되면 안될 것이다. 그러나 인증서 위조 가능성은 존재한다. 왜냐하면 디지털 서명 방식을 사용하고 있기 때문이다. 인증서 위조 방법은 두 가지가 있다. 첫 번째가 인증기관의 비밀키를 알아내는 방법이고, 두 번째는 디지털 서명에 사용되는 해쉬 알고리즘의 충돌(Collision) 문제를 이용하여 위조하는 방법이다. 어느 것으로든 인증서가 위조되면 어느 누구도 기술적으로 위조라는 사실을 증명할 수 없다. 위조 인증서는 디지털 검증 방식에 의해 모두 유효하게 판정되기 때문이다. 첫 번째 방법은 디지털 서명에 있어서 원천적인 문제이다. 따라서 본 논문은 두 번째 방법인 해쉬 알고리즘의 충돌 문제를 이용한 위조를 해결하는 방법에 대해 연구한다. 또한 인증 경로를 최적화하는 방법에 대해서도 연구한다.
