In this paper, a zero trust-based complex biometric authentication was proposed in a passwordless environment. The linkage of FIDO 2.0 (Fast IDENTITY Online) transaction authentication platforms was designed in conjunction with metaverse. In particular, it was applied with the location information of a smart terminal according to a geomagnetic sensor, an accelerator sensor, and biometric information for multi-factor authentication(MFA). At this time, a FIDO transaction authentication platform was presented for adaptive complex authentication with user's environment through complex authentication with secondary authentication based on situational awareness such as illuminance and temperature/humidity. As a result, it is possible to authenticate secondary users based on zero trust with behavior patterns such as fingerprint recognition, iris recognition, face recognition, and voice according to the environment. In addition, it is intended to check the linkage result of the FIDO platform for complex integrated authentication and improve the authentication accuracy of the linkage platform for transaction authentication using FIDO2.0.

To verify remitter's identity when the remitter transfers money to a recipient using an electronic financial service provided by the financial institution, the remitter inputs the information; such as the withdrawal account number, the withdrawal amount, the password pre-registered with the financial company, or the information from authenticating medium that is previously distributed by the financial institution. However, the 1-Way transaction between the financial institution and the remitter is exposed to a great risk of accidents such as an anomaly remittance or a voice phishing fraud. Therefore, in this study, we propose a 2-WAY trade verification model for electronic financial transaction that can be mutually agreed by allowing the recipient to share the transaction information with the remitter and the financial company. We have improved the traditional electronic financial transaction's method by replacing it to 2-WAY trade method, and it is used for various purposes; such as preventing an error within the remittance or voice phishing fraud, enhancing loan transaction and contract transaction, etc. Through these variety of applications, we are expecting to reduce the inconveniences while improving the convenience of financial transaction and vitalizing the P2P transaction of financial institution.

This paper is to analyze how Walt Whitman developed the theme and structure of Leaves of Grass with his ideal of democratic vistas. Whitman established his identity as an inspired poet, having faith in the divinity of man based on transcendental belief. After being awakened to the transcendental truth, he practiced his own common world view--his democratic vistas. Whitman searched for the unity with nature and identified his self with "common man and his nation." The poetry expresses "cosmological and national ideology" dedicated to the creation of an ideal nation united in eternal freedom and peace. By portraying common cosmic and national theme in terms of his individual personality, he brought various paradoxical and controversial ideas into one thing, namely "democracy", fusing diversity into unity. As in the symbol of the grass, there is a unity in variety reflected by democracy in a cosmological and political compound. With the form of free verse, he could express his liberal unrestrained and mystical thoughts of democracy. This new form has been associated with the poet's strong consciousness of the need for modernization in his country. He willingly assumed "the role of prophet and public voice for American democrat" with the rolling catalogues and I-persona which formed a sense of the common man and common things of America. Whitman pioneered a democrat literature with simple and dynamic tone and style. He successively pursued the democratic vistas in his Leaves of Grass.

Phishing is an attack to theft an user's identity by masquerading the user or the device. The number of phishing victims are sharply increased due to wide spread use of smart phones and messenger programs. Smart phones can operate various wi-fi based apps besides typical voice call and SMS functions. Generally, the messenger program such as Kakao Talk or Nate On is consisted of client and server functions. Thus, the authentication between the client and the server is essential to communicate securely. In this paper, we propose the messenger authentication protocol safe against smart phone phishing. To protect communications among clients, the proposed method provides message encryption and authentication functions.

Recently, technologies are being developed to recognize and authenticate users using bioinformatics to solve information security issues. Biometric information includes face, fingerprint, iris, voice, and vein. Among them, face recognition technology occupies a large part. Face recognition technology is applied in various fields. For example, it can be used for identity verification, such as a personal identification card, passport, credit card, security system, and personnel data. In addition, it can be used for security, including crime suspect search, unsafe zone monitoring, vehicle tracking crime.In this thesis, we conducted a study to recognize faces by detecting the areas of the face through a computer webcam. The purpose of this study was to contribute to the improvement in the accuracy of Recognition of Face Based on CNN Algorithms. For this purpose, We used data files provided by github to build a face recognition model. We also created data using CNN algorithms, which are widely used for image recognition. Various photos were learned by CNN algorithm. The study found that the accuracy of face recognition based on CNN algorithms was 77%. Based on the results of the study, We carried out recognition of the face according to the distance. Research findings may be useful if face recognition is required in a variety of situations. Research based on this study is also expected to improve the accuracy of face recognition.

The use of Multiparty Conference service based on SIP for VoIP provides is gradually magnified, and the work for continuous development and standardization on SIP is in the process of advancing. But, currently it is impossible for SIP to support identity discovery and distribution of each participant for multiparty conference. In this paper, we propose a SIP extension for guaranteeing security on the multiparty conference using SIP by adding new method and reconstructing header informations. With this, it is also possible to identify discovery and to distribute each participant using SIP extension when a call is established for closed multiparty conference.

Summary. With the advent of the internet and the concept of social network service, people of present days are flooded daily with new varieties of the communication channel. One of the most affected group of people may be singing artists. This over-growing number of communication channels pushes singers to put just as many efforts to establish and groom his or her unique identity as an artist. In old 'pre-internet' days, any singing artist's superficial features, like the tone of voice or stage presentation, were the only transcriptive criteria upon which the artist was adjudicated. New developments in technology, however, have set a new paradigm for singing artists of the present day. Respective criteria of today extend beyond the realm of music and comprise musicianship, requiring much scrupulous attention on the various area to propagate and protect one's unique identity as an artist. In light of this phenomenon, this study looks into Mr. Lee, Seung Hwan whom may undoubtedly be one of the most representative ballad singers of 90's. We can probably see his music in 5 features such as Rock Sound based on using various instruments, World Music Sound, Massive Choir, Challenge for the New Style, Lyrics of Life. As a singer-songwriter, he colored numerous albums and influenced the era, unlike many others. He still works vigorously, worthy of his epithet, a 'present-progressive' artist. The object of this study is how Mr. Lee has been proactively dealing with the phenomenon above.

Eugene O'Neill's one-act play Before Breakfast (1916) depicts a morning scene of a married couple who live in a slovenly flat at Greenwich Village. There is no apparent dramatic action occurring in the play. Instead, the play is full of Mrs. Rowland's incessant complaints about her husband Alfred's loafing around bars with artists friends, neglecting his role as breadwinner. An irony is that every morning she prepares breakfast for the good-for-nothing husband even in the moment of complaining. It is worth noting that Alfred is an 'unseen character' who is never directly observed by the audience but is only described by her wife. Deprived of all chances to speak and present himself on stage, he is kept in the room throughout the play. In contrast, Mrs. Rowland dominates the stage, monopolizing language and action. The audience has to listen to her, judge from her statements, and take her one-sided complaints. The accused husband, with zero chance of showing up and defending himself, has no choice but to be the sinner as the wife intends. Another irony is that the audience's feeling about the situation is quite different from what is expected. The wife's complaints are regarded to be unfair and groundless in the reason that the situation is monopolized by her. In case of the husband, in contrast, the loss of voice and presence stresses the injustice of his dead-lock situation. In other words, the 'absent' quality of Alfred works to evoke the audience's sympathy for himself and subsequently makes his presence recognized, not visually but emotionally, by the audience throughout the play. Discovered in this paradoxical moment where the spectators understand or 'see' the status of the unseen and the devoiced message is successfully conveyed to the listeners, is the theatricality of absence. Adding to the function as theatrical device, the 'unseen character' Alfred works as a device of self-reflection to mirror the author's own life. Alfred, the alter-ego of O'Neill, effectively exorcises the author's life-long feeling of guilty as the unfaithful husband and father in the unhappy first marriage, successfully evoking the audience's sympathy for himself.

Recently the range of mobile phone's usage has become more widely since phone has the function of data communication and voice communication. In addition, the request of users who wish to represent their identity on their mobile phones by storing some kinds of multimedia data such as images and melody has increased. There are two different methods for downloading the multimedia data; one method accesses a wireless internet server to download the data and another method downloads the data from PC directly. While the first one requires extra fee for downloading the data, the second method has weakness to modify the original data and it cannot be used in GSM phone yet since it is developed for CDMA phone. In this paper, we introduce a PC-based download application system that enables the users to download multimedia data from PC to GSM phone very easily.

Conventionally, there were few cases in which a medical accident became a criminal case in Japan. However, after the serious malpractice such as the Yokohama City University Hospital case, prosecutors came to be less hesitant to prosecute a malpractice. In a medical accident, the attribution of the responsibilities among medical personnel becomes one important element of the proof of negligence. The Supreme Court concluded that, when the attribution of the responsibilities is not established among medical personnel to confirm the identity of the patient like the Yokohama City University Hospital case, all the personnel who were involved bear the responsibilities to identify the patient. For serious cases which requireut most carefulness fortreatment such as the Saitama Medical University Hospital case, not only the chief physician in charge of the case concerned but also the director of the branch at the university hospital bear the responsibilities to confirm the treatment policy of the case. After the acquittal of the Ohno Hospital case, the voice demanding more prudent prosecution of malpractices has become stronger than before. Meanwhile, Ministry of Health, Labour and Welfare introduced Medical Accidents Investigation System for the prevention of medical accident and, has reinforced the third party inspection of medical accidents.
