Today, Internet users start off using heavily SNS(Social Network Site) such like, Facebook, Twitter. The reason of the growth of using SNS would be closely related to the various services of gaming, playing, entertainment items, sharing information etc., provided by the SNS, technically, the most important one out of the services provided would be behaving of sharing knowledge among people who connected and networked in the site. In sum, we assume that the users may communicate well each other and pay attention to build closely a social network using that kind of activities. However, nevertheless the new trends of communications and sharing knowledge become popular, researchers have just began the research issues in explaining why Internet user rush into SNS and enjoy the time in there. Therefore, we investigate on the reasons of posting knowledge voluntarily in the SNS and how others response to the posted information and actually affected by the behavior. We appled personal relation and social identity theory for this study, which personal relation in SNS may affect on social identity and make them produce knowledge generation. We found that social identity and involvement in SNS is closely related and influence knowledge creation and generation. This empirical study resulted in the importance of social relations in SNS, which leads to a sharing knowledge.

With the increasing frequency of incidents related to personal information leaks, there is a growing concern about personal information protection. Moreover, with the emergence of blockchain technology, there is a heightened interest in self-sovereign identity models applied through blockchain, with ongoing research on Decentralized Identifiers (DID) to achieve this. However, despite universities storing and utilizing significant information such as personal data, their computer systems are operated and managed based on centralized systems, leading to annual occurrences of personal data breaches. Therefore, this paper proposes and implements a DID-based computing system applicable within universities. Additionally, it establishes and executes prominent services within the university context. The proposed system ensures users' self-sovereign identities through verifiable credentials, enabling the establishment of a secure integrated information system within the university, departing from traditional centralized systems.

This paper analyzes the trends of identification proofing services(PIPSs) to identify and authenticate users online and proposes a method to improve PIPS based on alternative means of resident registration numbers in Korea. Digital identity proofing services play an important role in modern society, but there are some problems. Since they handle sensitive personal information, there is a risk of information leakage, hacking, or inappropriate access. Additionally, online service providers may incur additional costs by applying different PIPSs, which results in online service users bearing the costs. In particular, in these days of globalization, different PIPSs are being used in various countries, which can cause difficulties in international activities due to lack of global consistency. Overseas online PIPSs include expansion of biometric authentication, increase in mobile identity proofing, and distributed identity proofing using blockchain. This paper analyzes the trend of PIPSs that prove themselves when identifying users of online services in non-face-to-face overseas situations, and proposes improvements by comparing them with alternative means of Korean resident registration numbers. Through the proposed method, it will be possible to strengthen the safety of Korea's PIPS and expand the provision of more reliable identification services.

When an individual needs to prove eligibility, it is sufficient to know whether or not s/he meets the eligibility, but any existing method inevitably exposes the identity of the owner or unnecessary additional information in the process of providing personal information. In this paper, among the immutable items of personal information such as gender, date of birth, and place of birth, we propose a method in which the owner provides only essential item(s) to the eligibility verifier with each iterm marked on one option among multiple choices. In this way, the eligibility verifier can access the combination of items stored in the blockchain with the consent of the information owner, and can safely store the access history by requesting recording in the blockchain again. In the proposed method, the user does not worry about his/her identity being revealed or his/her personal information being overly exposed, and the eligibility verifier can check only necessary items and search later records without separately storing the records.

This study examined effects of the social-psychological motivations to use Instagram (i.e., identity seeking, social interaction) and narcissistic personality on personal attachment to Instagram and intention to post photos on Instagram. Identity seeking, social interaction and narcissistic personality (i.e., grandiose/exhibition) had significant positive effects on personal attachment to Instagram. Identity seeking and social interaction had significant positive effects on intention to post photos on Instagram. However, narcissistic personality had no effect on the intention to post photos on Instagram. The study results support the theory of the extended-self in the digital context. This study also provides useful information to help organizations understand why people use Instagram as well as how to take advantage of Instagram to enhance their services and consumer experiences.

As the computer technology grows so fast, it can affect the human life in every fields. Specially, advent of Digital epoch is changing human life completely. In the past, people should get the information through the mass-media. But these days we can produce and provide some information through new media, Internet. In other words, two-ways communication like internet make individual be the producer in the information stream. Especially, net generation is different form the old generation and they want to express themselves distinctively from others. Nevertheless, they can't have the chance to express their identity properly and only they try to satisfy their needs by consuming special goods. In this article, I want to suggest a program that an individual can express their own identity and image. I will transform CIP (Corporate Information Program) and adjust it to an individual case. This is different from the previous study that emphasize the external factor figure, etc. First, we will find the MI(mind identity) and the BI(behavior identity). Second, we will present the VI(visual identity) by using two factors. - MI, VI. Finally, we will analyze them totally and make the PI(personal identity ) that can express their own identity and philosophy well. Through this programs, they can express themselves well and get the chance to think creatively. I am sure this program will have more implications about image strategy.

In a virtual community, one can possess multiple identities and pretend to be different by creating self-identity in contrast with his or her actual self. Does false identity undermine the qualitative growth of a virtual community by reducing members' accountability? Or does it stimulate their contributive behaviors by ensuring freedom of speech? It is imperative to understand the effects of multi-identity considering the distinct properties of a virtual community in which people easily change their identities at little or no cost. To answer these questions, we adopted the concept of self-discrepancy from the social psychology theory rooted in the concept of the self and developed a theoretical model to predict quality of contribution of the individual member in virtual communities. Based on the self-discrepancy theory, we first identified two different domains of the self: (1) an "actual self" that consists of attributes that the person believes he or she currently possesses in real life and (2) a "cyber self" that consists of attributes the person believes he or she possesses in a virtual community. Next, we derived an index for two different types of self-discrepancy by using the differences between the actual and the cyber identities: Personal Self-discrepancy and Social Self-discrepancy. Personal Self-discrepancy reflects the degree of discrepancy between actual and cyber identity regarding a person's intelligence, education, and expertise. Social Self-discrepancy reflects the degree of discrepancy between actual and cyber identity regarding a person's morality, sociability, and accordance with social norms. Finally, we linked them with sense of virtual community, perceived privacy rights, and quality of contribution to examine how having a multi-identity influences an individual's psychological state and contributive behaviors in a virtual community. The results of the analysis based on 266 respondents showed that Social Self-discrepancy negatively influenced both the Sense of Virtual Community and Perceived Privacy Rights, while Personal Self-discrepancy negatively influenced only Perceived Privacy Rights, thereby resulting in reduced quality of contribution in virtual communities. Based on the results of this analysis, we can explain the dysfunctions of multi-identity in virtual communities. First, people who pretend to be different by engaging in socially undesirable behaviors under their alternative identities are more likely to suffer lower levels of psychological wellbeing and thus experience lower levels of sense of virtual community than others. Second, people do not perceive a high level of privacy rights reflecting catharsis, recovery, or autonomy, even though they create different selves and engage in socially undesirable behaviors in a virtual community. Third, people who pretend to be different persons in terms of their intelligence, education, or expertise also indirectly debase the quality of contribution by decreasing perceived privacy rights. The results suggest that virtual community managers should pay more attention to the negative influences exercised by multi-identity on the quality of contribution, thereby controlling the need to create alternative identities in virtual communities. We hope that more research will be conducted on this underexplored area of multi-identity and that our theoretical framework will serve as a useful conceptual tool for all endeavors.

This study conducted a survey with 300 male respondents in their 20s to 50s, in order to examine the influence of personal variables, identity of gender roles, self-esteem and social-cultural attitude towards appearance on metro-sexual consumption. The findings are as follows: First, the majority of respondents experienced metro-sexual consumption in passive ways, such as purchasing cosmetics or perfume. Second, self-esteem differed by classification of identity of gender roles and the self-esteem was the most highly rated in non-classified, followed by in femininity, masculinity and androgyny. On the other hand, the non-classified group appeared to have the most highly social and cultural attitude toward appearance. Lastly, when examining the effect of personal variables, identity of gender roles, self- esteem and social-cultural attitude toward appearance on metro-sexual consumption, the results showed that the younger respondents who spend the highest monthly expenses on appearance, belong to the androgynous group and have the social-cultural attitude, are more likely to have a greater tendency towards metro-sexual consumption.
