In order to use an Internet service, it is a general procedure that user subscribes to the service and then registers her or his id(identifier). As Internet has been more widely used, however, user has more and more ids than ever before. In this environments, whenever user uses an Internet service, she or he must authenticate to the service provider, which makes her or him inconvenient. As user's data is scattered and unmanaged on various web sites, user privacy has been revealed more often. This paper specifies e-IDMS which ETRI has been developing to solve such problems. e-IDMS is an Internet ID(IDentity) management system based on ID Federation Mechanism e-IDMS provides ID Federation-based facilities such as composite authentication, Internet SSG, ID information management, privacy protection and interactive query. e-IDMS is used in establishing integrated ill management system for public institutions.

The International Maritime Organization (IMO) has defined e-Navigation for the purpose of providing safe and efficient maritime information and communication services. Currently, a maritime cloud is being developed as a communication infrastructure for e-Navigation services. In this paper, we design the structure of vessel ID importation system which can efficiently register the maritime ID in the maritime cloud environment.

eID는 여러 편의성을 제공하지만, 개인정보보호의 불확실성에 대한 우려로 활성화가 쉽지 않다는 단점이 있다. 이미 선진국에서는 eID의 도입을 추진해 왔으며 특히 EU에서 적극적으로 시도한 바 있다. 안전한 eID 시스템을 위해서는 개인정보보호 뿐 아니라 시스템 자체의 보안에 대한 고려도 동시에 이루어져야 한다. 보안성이 신뢰되지 않는다면, 개인정보보호에 대한 신뢰도 존재할 수 없을 것이다. 본 고에서는 EU에서도 특히 활발한 움직임을 보이고 있는 독일의 eID 현황 및 보안 메커니즘을 살펴본다. 그리고 안전한 eID 시스템 구성을 위한 보안 요구사항을 분석한다.

The problem of unsolicited e-mail has been increasing for years, so many researchers has studied about spam filtering and prevention. In this article, we proposed a faster spam prevention algorithm based on userID instead of full email address. But there are 2% of false-negatives by userID. In this case, we store those domains in a DB and filter them out. The proposed algorithm requires small DB and 3.7 times faster than the e-mail address comparison algorithm. We implemented this algorithm using SPRSW(Spam Prevention using Replay Secrete Words) to register userID automatically in userID DB.

최근 여러 선진국을 중심으로 전자신분증 기능을 갖는 eID 카드가 도입되고 있다. eID 카드의 도입을 위해서는 안전한 개인정보보호 대책이 필수적으로 고려되어야 한다. 그러나 현행 eID 인증시스템에서 중간자공격에 대한 위험성이 기존 연구 문헌에서 제기된 바 있다. 본 논문에서는 기존의 eID 인증방식을 개선하여, 중간자공격으로부터 안전한 방식을 제안하고자 한다. 제안한 방식으로 인증 과정에서의 개인정보 노출에서 안전을 보장받을 수 있다.

Electronic identity (e-ID) card based on smartcard is a representative identity credential for on-line and off-line personal identification. The e-ID card can store the personal identity information securely, so that the information can be accessed fast, automated identity verification and used to determine the cardholder's authorization to access protected resources. Due to such features of an e-ID card, the number of government organizations and corporate enterprises that consider using e-ID card for identity management is increasing. In this paper, we present an authentication framework for access control system using e-ID cards by discussing the threat environment and security requirement against e-ID card. Specifically, to accomplish our purpose, we consider the Personal Identity Verification system as our target model.

The purpose of this study was to investigate the etiological distribution, therapeutic outcome, and survival time in canine epilepsy. The medical records of 57 epileptic dogs were reviewed for the evaluation of etiological distribution. Among them, 27 dogs (47%) and 30 dogs (52%) had idiopathic epilepsy (IdE) and structural epilepsy (StE), respectively. Twenty-nine dogs (IdE: 16 dogs, StE: 13 dogs) were evaluated for therapeutic outcome and survival time. The incidence of generalized epileptic seizure (IdE, 56% vs. StE, 44%; P = 0.043) and the median seizure frequency at the time of first presentation (IdE, 2.0/month vs. StE, 13.3/month; P < 0.01) were significantly different between the two groups. Although pre-treatment seizure frequency and duration were not different, the median duration of seizure in the IdE group (0.5 min) was significantly shorter than that in the StE group (3 min) after treatment (P < 0.01). In addition, the median frequency of seizure was relatively lower in the IdE group (0.25/month) compared to the StE group (2.00/month) following antiepileptic therapy (P = 0.053). The median survival time of the IdE group (1.5 years [95% CI, 1.0-2.3 years]) was significantly longer than that of the StE group (0.4 year [95% CI, 0.2-1.3 years]) (P < 0.01). The information on etiological data and intracranial lesions may be useful for predicting treatment response and prognosis in epileptic dogs.

현재 국내에서 사용되고 있는 신분 인증 시스템은 주민등록번호와 같은 개인 정보를 기반으로 인증을 수행하여, 프라이버시 침해 위협이 존재한다. 그 해결 방안으로 가상 ID를 이용하는 I-PIN과 e-ID 카드가 제안되었지만, 문제점은 ID와 패스워드만 알고 있다면 누구나 도용이 가능하고 오프라인에서 사용하는 플라스틱 카드의 경우 위 변조가 가능하다는 한계를 갖는다. 본 논문에서는 주민등록번호를 대체할 식별 데이터인 QR-ID를 생성하고, 이에 기반을 둔 QR-ID 카드를 제안한다. QR 코드는 인식기에 대한 제약이 적고 일부 데이터 조작만으로 새로운 QR 코드 생성이 가능하여 노출 시 새로운 ID로 갱신할 수 있으며, QR-ID는 소유자의 바이오메트릭 데이터로 암호화되어 타인이 복호화 할 수 없다.

Ixeris dentata (ID, family Asteraceae), called Seumbakuy in Korea, was fermented with lactic acid bacteria (LAB) and their antiallergic activities were investigated. Fermentation of ID with Bifidobacterium breve or Lactobacillus acidophilus increased its inhibition of degranulation in RBL-2H3 cells induced by the IgE-antigen complex. Oral administration of these extracts to mice inhibited the passive cutaneous anaphylaxis (PCA) reaction induced by the IgE-antigen complex and scratching behaviors induced by compound 48/80. The fermented ID more potently inhibited the PCA reaction and scratching behaviors than the non-fermented one. These extracts also inhibited mRNA expression of TNF-${\alpha}$ and IL-4, as well as NF-${\kappa}B$ activation in RBL-2H3 cells induced by the IgE-antigen complex. These findings suggest that LAB fermentation improves ID-mediated inhibition of IgE-induced allergic diseases such as rhinitis and asthma, and that ID works by inhibiting degranulation and NF-${\kappa}B$ activation in mast cells and basophils.
