In this paper, we developed a mobile student ID providing a self sovereignty identity (SSI) which replaces the conventional plastic-type student ID that includes private information of a student such as a name, a student number, a facial photo, etc. The implemented mobile student ID solves the problem of exposing student's identity due to a loss or a theft of a plastic-type student ID, and it has a structure and process of FRANCHISE model which is developed by a concept of a decentralized Identity(DID) of a Blockchain, in which specialized for convenience as an electronic student ID through an application on a smart phone device. In addition, it protects student's privacy by controlling personal information on oneself. By using a smartphone, not only it easily identifies the student but also it expands to several services such as participation in school events, online authentication, and a student's exchange program among colleges.

Many emerging mobile ad-hoc network application communications are group-oriented. Multicast supports group-oriented applications efficiently, particularly in a mobile environment that has a limited bandwidth and limited power. Energy effectiveness along with safety are 2 key problem in MANET design. Within this paper, MANET is presented with a stable, energy-efficient clustering technique. In this proposed work advanced clustering in the networks with ticket ID cluster manager (TID-CMGR) has formed in MANET. The proposed routing scheme makes secure networking the shortest route possible. In this article, we propose a Cluster manager approach based on TICKET-ID to address energy consumption issues and reduce CH workload. TID-CMGR includes two mechanism including ticket ID controller, ticketing pool, route planning and other components. The CA (cluster agent) shall control and supervise the functions of nodes and inform to TID-CMGR. The CH conducts and transfers packets to the network nodes. As the CH energy level is depleted, CA elects the corresponding node with elevated energy values, and all new and old operations are simultaneously stored by CA at this time. A simulation trial for 20 to 100 nodes was performed to show the proposed scheme performance. The suggested approach is used to do experimental work using the NS- simulator. TIDCMGR is compared with TID BRM and PSO to calculate the utility of the work proposed. The assessment shows that the proposed TICKET-ID scheme achieves 90 percent more than other current systems.

Android that was made by Google and Open Handset Alliance is the open source software toolkit for mobile phone. In a few years, Android will be used by millions of Android mobile phones and other mobile devices, and become the main platform for application developers. In this paper, the integrated login application based on Google's Android platform is developed. The main features of the mobile combination login application content based on Android are as follows. First, the application has more convenient login functionality than the functionality of general web browser as the web browser of the mobile-based applications(web browser style applications) as well as security features and faster screen(view) capability by reducing the amount of data transfer. Second, the application is so useful for management of ID and Password, and it can easily manage multiple ID information such as message, mail, profile. The results of performance evaluation of the developed application show the functionality that can login many kinds of portal sites simultaneously as well as the ability that can maintain login continuously. Currently, we are trying to develope a couple of the technologies that can insert multiple accounts into one ID and check all information on one screen.

The clean mobile robot for wafer transfer is AGV that carry each wafer to each equipment. It has wafer handling technology, wafer ID recognition technology, position calibration technology using vision system, and anti-vibration technology. Wafer loading/unloading working accuracy is within ${\pm}$1mm, ${\pm}$3$^{\circ}$. By application of this AGV, we can reduce the manufacturing tack time and bring cost down of equipment.

Currently widely used IP cameras provide the ability to control IP cameras remotely via mobile devices. To do so, the IP camera software is installed on the website specified by the camera manufacturer, and authentication is performed through the password between the IP camera and the mobile device. However, many products currently used do not provide a secure channel between the IP camera and the mobile device, so that all IDs and passwords transmitted between the two parties are exposed. To solve these problems, we propose an authentication and key exchange protocol using ID-based signature scheme. The proposed protocol is characterized in that (1) mutual authentication is performed using ID and password built in IP camera together with ID-based signature, (2) ID and password capable of specifying IP camera are not exposed, (3) provide forward-secrecy using Diffie-Hellman key exchange, and (4) provide security against external attacks as well as an honest-but-curious manufacturer with the master secret key of the ID-based signature.

본 논문에서는 ATSC 기반 국내 지상파 DTV 방송신호를 대상으로 ATSC A/65c(Program and System Information Protocol; PSIP) 및 A/57b(Content Identification and Labeling for ATSC Transport) 표준규격 기반의 방송프로그램ID 규격을 제안한다. 특히, 현재 방송사 내부적으로 운영되고 있는 콘텐츠 식별관리 방식의 독자성을 유지하고, 지상파방송 서비스 환경의 특수성을 반영한 지상파 방송프로그램 식별정보인 방송프로그램ID 구조를 제시한다. 또한 방송프로그램ID 삽입/추출기의 구현 및 실험과정을 통하여, 국내 지상파 DTV 방송 송수신규격과의 정합 및 방송프로그램ID의 기능 검증을 수행한다.

인터넷 인구가 크게 증가함에 따라 인터넷 상의 ID와 개인정보 관리 문제가 크게 대두되고 있다. 이에 대한 해결책으로 통합 ID 관리 시스템이 고안되었으며 이 방법들 중 하나로 사용자 중심의 분산형 인증을 제공하는 OpenID가 있다. 현재 OpenID는 보안적인 기능을 담당하는 신뢰모델에 대한 표준화가 되어있지 않기 때문에 ID와 Password 이외에 사용자를 인증하는 다른 방법이 없는 문제점이 있다. 본 논문에서는 OpenID의 인증 및 신뢰성을 강화하기 위해 OTP 생성 매체인 Mobile One Time Password를 적용한 OpenID기반의 MOTP를 이용한 사용자 인증 시스템을 제안하고 설계한다.

In 2008, ETRI developed a new mobile digital ID wallet, in which anyone can store personal information and PKI credential. When the wallet is used, privacy protection is one of the most important problems and personal information should be protected under various usage scenarios such as exchanging sensitive information in on/off-line environments, joining as a new member in the web site, etc. In this paper, we propose a triangular trust management scheme that can effectively manage trustness and also protect sensitive personal information. This scheme relies on three techniques: PKI, reputation and condition (situation context). We implemented prototype of our scheme, and tested it under various scenarios, which showed that the proposed scheme can effectively be used for diverse cases.
