The spread of smart phones provides users with a variety of services, making their lives more convenient. In particular, financial transactions can be easily made online after user authentication using a smart phone. Users easily access the service by authenticating using a PIN, but this makes them vulnerable to social engineering attacks such as spying or recording. We aim to increase security against social engineering attacks by applying the authentication method including imaginary numbers when entering a password at the door lock to smart phones. Door locks perform PIN authentication within the terminal, but in smart phones, PIN authentication is handled by the server, so there is a problem in transmitting PIN information safely. Through the proposed technique, multiple PINs containing imaginary numbers are generated and transmitted as processed values such as hash values, thereby ensuring the stability of transmission and enabling safe user authentication through a technique that allows the PIN to be entered without exposure.

The literature of unfair labeling and advertising(ULA) was reviewed, along with the requirement for establishing an obligation to compensate for damage(OCD) by it based on the Act on Fair Labeling and Advertising(FLAA). ULA covers cases of possible deception or misleading consumers and thereby undermining fair trade order, or making other business entities do so. FLAA regulates OCD by ULA, but the Civil Act should also be considered for its effective results since the Act regards ULA as unlawful and duty bound to make compensation for damages arising therein. In this context, the study analyzed qualitatively 17 supreme court precedents related to OCD by ULA among a total of 119 by advertising to find the characteristics of the judgemental principles. It is found that most principles came from FLAA and the Act focusing on the meaning of false or exaggerated advertising, which is one of the following five ULA types according to its standards of judgment: its requirement for fraudulent acts, the meaning of damage by it, the perspective of calculation of damages, the requirement of OCD, and the characteristics of claim for damages. A more effective policy is suggested based on FLAA and related research should be continually carried on.

The Chinese counterfeits has begun to gain great attention recently because of the drastic increase in its volume. The consumption of counterfeit harms to manufacturer who spend millions of dollars to create and develop new product. The counterfeits in Chinese can cause international dispute and lower national reputation. The purpose of this study were to examine if the buyers of counterfeits tend to care more about interpersonal relationship than non-buyers among Chinese. Data were gathered by surveying Chinese consumer living in Beijing, Shanghai, and Guangzhou metropolitan area using convenient sampling, and 480 questionnaires were used in the statistical analysis. In analyzing data, descriptive statistics, factor analysis, structural equation modeling with AMOS were conducted. The results of this study were follows, first, attitude toward counterfeits was classified into three factors such as interpersonal relationship, perception, and involvement. It is general belief that attitudes toward counterfeits were correlated with on brand attachment, however this study show that the buyers of counterfeits tended to purchase counterfeit goods as more alternatives of genuine(original) product than non-buyers. Perhaps, the buyers of counterfeits tended to have lower consumer ethics than non-buyers because they value counterfeit high. It is generally accepted that both a producer and a buyer violate the laws, but they are rather generous for buyer. The results of this study suggest consumers' attitude towards counterfeit need to be changed, following consumer education and strict law enforcement. Based on these results, global brand marketing strategies for luxury goods were suggested.
