현재 전자여권은 미국을 중심으로 도입이 시작, 전 세계 36개국에서 발행되고 있으며 우리나라도 2008년 시작으로 비자 면제국 가입을 위한 기본 조건으로 전자여권 전환 작업이 진행되고 있다. 전자여권의 도입과 함께 지문 정보 저장에 대한 프라이버시 문제 및 전자여권 내 정보 보호의 문제 등이 대두 되고 있다. 전자여권에서 사용 되고 있는 프로토콜 중의 하나인 OSEP의 취약점 및 문제점을 사전에 알아내 개인 정보 유출을 미연에 방지할 수 있도록 정형 명세 및 검증 도구인 AVISPA를 사용하여 접근해 보았다. 본 논문에서는 AVISPA를 이용한 명세 및 검증을 통해 OSEP(On-Line Secure E-passport Protocol)의 취약점을 효과적으로 발견할 수 있는 방법을 제안한다.

Background: In the emergency department (ED), adequate pain control is essential for managing patients; however, children with pain are known to receive less analgesia than adults with pain. We introduce the Pain Passport to improve pain management in paediatric patients with suspected fractures in the ED. Methods: This was a before-and-after study. We reviewed the medical records of paediatric patients who were primarily diagnosed with fractures from May to August 2015. After the introduction of the Pain Passport, eligible children were enrolled from May to August 2016. Demographics, analgesic administration rates, time intervals between ED arrival and analgesic administration, and satisfaction scores were obtained. We compared the analgesic prescription rate between the two periods using multiple logistic regression. Results: A total of 58 patients were analysed. The baseline characteristics of subjects during the two periods were not significantly different. Before the introduction of the Pain Passport, 9 children (31.0%) were given analgesics, while after the introduction of the Pain Passport, a significantly higher percentage of patients (24/29, 82.8%) were treated with analgesics (P < 0.001). The median administration times were 112 (interquartile range [IQR], 64-150) minutes in the pre-intervention period and 24 (IQR, 20-74) minutes in the post-intervention period. The median satisfaction score for the post-intervention period was 4 (IQR, 3-5). The adjusted odds ratio for providing analgesics in the post-intervention period was 25.91 (95% confidence interval, 4.36-154.02). Conclusions: Patient-centred pain scoring with the Pain Passport improved pain management in patients with suspected fractures in the paediatric ED.

The purpose of this study is to present an approach to the "Digital Health Passport" (DHP), which will be the most important in the change of the travel industry among the sudden environmental changes brought about by COVID-19. To this end, this study reviewed a variety of empirical literature on DHP, and proposed a framework for DHP based on literature review. The framework is composed of travel intention, health information provision intention, and new technology acceptance/adoption of tourists. First, in terms of travel intention, providing information to DHP should not undermine the travel intention of the travelers. It should be possible to facilitate the travelers' enjoyment by using the information provided by the traveler. In addition, there is a need to assure that the data provided by travelers is managed in a reliable way. Second, it is necessary to understand why the travelers want to provide additional personal information (information disclosure), rather than seeing healthcare information only in terms of mandatory information provision. Finally, from the perspective of new technology, it is necessary to understand the intention of travelers to use/adopt DHP. The key implication of this work is that it proposed a DHP framework for realizing the travel bubble to predict and respond to foreign travelers' behaviors.

This paper proposes a novel method for the recognition of passports based on the CDM(Conditional Dilation Morphology) masking and the ART2-based RBF neural networks. For the extraction of individual codes for recognizing, this paper targets code sequence blocks including individual codes by applying Sobel masking, horizontal smearing and a contour tracking algorithm on the passport image. Individual codes are recovered and extracted from the binarized areas by applying CDM masking and vertical smearing. This paper also proposes an ART2-based hybrid network that adapts the ART2 network for the middle layer. This network is applied to the recognition of individual codes. The experiment results showed that the proposed method has superior in performance in the recognition of passport.

전자여권에 적용된 보안기술 중 BAC(Basic Access Control)는 전자여권의 IC칩에 내장된 여권 소지자의 신상정보를 여권을 제출한 상태에서만 확인할 수 있도록 하는 접근제어 메커니즘이다. 하지만 BAC에 사용되는 비밀키의 생성을 위해 전자여권 내의 MRZ 정보를 구성하고 있는 여권 소지자의 신상정보가 사용되기 때문에 비밀키에 대한 전수조사 공격에 취약할 수 있다. 이에 본 논문에서는 한국 전자여권의 BAC 과정에서 사용되는 비밀키의 보안성을 분석한다.

Nationalism can solidify national unity and ideology but sometimes causes conflicts in human societies. Interestingly, it affects tiger conservation as well. Collaborative efforts are imperative for tiger conservation due to their vast home ranges which cross political boundaries and the limited financial resources. However, tiger states have not shown substantial commitment to collaboration. The nationalism that is entrenched in tiger conservation provides a credible explanation for this passive collaboration among nations. One type of nationalism occurs within a country by favoring one particular subspecies over another. The other type of nationalism occurs when former range countries want tigers. Instead of contributing to saving tigers in current habitats, they are eager to bring tigers back to their political boundaries regardless of the tremendous financial resources required and the lower chance of success. Considering nationalism in tiger conservation, tigers, just like humans, may need a passport for a better chance to survive.

This paper presents the design of a certain highly efficient security policy negotiation of SPS(Security Policy System) using mobile agent system. The conventional IP security systems have some problems. A drawback to these systems is that the required policy between each security area is different. Another problem is not possible to guarantee whether a packet is transmitted through the same path by both directions and is protected by the same policy due to the topology of the network. Unlike conventional systems, the model developed herein can be resolved by using a mobile agent technology. If each domain needs a negotiation of security policy, a mobile agent manages the result of the negotiation in the form of a passport and guarantees the authentication and reliability each other by using the passport.
