In this paper, a new hybrid opto-digital multiple information hiding and real-time extracting system was suggested and implemented using a volume holographic optical correlator. The multiple information hiding system in which the multiple information can be hided in an arbitrary cover image was digitally implemented by using the combination of pseudo random sequence and Hadamard matrix. In addition, a real-time optical extraction system in which the hided multiple information in a cover image can be extracted in real-time was implemented by using a volume holographic optical correlator. In the VanderLugt-type holographic optical correlator used in this experiment, the multiful matched spatial filters corresponding each of the hided informations were recorded in a photorefractive crystal by using the moving window-based angular multiplexing scheme.

We designed a security improved document DRM for protecting document based military information which is transmitted in the military information system environment. The user should be could not access document which not related to his/her role and duty, and must view the only document appropriate for his/her role and security level according to the security level of document. We improved the security of document DRM by adding to the access control module in DRM server. Our system allows operation mode authorizations for the document, considering the user's role & security level and the security level of document. And it prevents indiscriminate access to the document and damage the confidentiality and integrity of information.

Using the service innovation system model, the development of Korean online game industry is analyzed. The model proposed by Gallouj (2002) is modified in order to reflect IT service characteristics such as network externalities. Success factors and innovations patterns of Korean online game industry are examined. First, at the early stage of her growth, Korean online game industry was not supported or coordinated by any Government policies unlike DRAM, CDMA or TFT-LCD. Many parts of technical and service innovations were unintentionally initiated by online game developing ventures without predeterminde strategies. Second, the online game industry is basically a service industry so that users' needs and technical and service characteristics are intertwined to produce innovation. The innovation system of the online game industry is quite different from conventional product technological innovation systems in a sense that there are no blueprints for innovation as well as major players in the system. Third, Government's policies for promotion of IT industry such as the broadband infrastructure installation policy, the hi-tech venture promotion policy and the military exemption policy contributed greatly to development of the online game industry. However, these policy tools were not intended for online game industry but in the end gave a great impact on the service innovation system of the online game industry.

Recently, the necessity of systematic security management system that consider company' character and environment has appeared because of increasing security accident continuously in domestic companies. However, most of companies has applied to only K-ISMS which is existing information security management system, although They are different from object, purpose and way of security level evaluation by companies. According to this situation, Many experts have questioned that there are many problems with effectiveness of introducing security management system. In this study, We established definition of information security management system, industrial security management system and research security management system through analysis of previous study and developed evaluation item which can implement security in whole industry comparing and analyzing the control items of them. Also, we analyzed existing security level evaluation and suggest design direction of industry-centric security level evaluation model considering character of industry.

Mobile payment system using NFC attracted attention as the mobile payment market grows due to the fast diffusion of smart phones. However, non NFC mobile payment recently appeared because of the slow growth of infrastructure for NFC. With advent of Non NFC mobile payment applications, mobile payment industry is in developing trend. Non NFC mobile payment revitalizes the market by overcoming the limit of NFC with the smart applications using bar code and QR code payment, and providing various discounts, membership benefits and payment information. Therefore, this paper analyzed the intention of continuous use with the quality of mobile payment application based on the information system success model. Three categories of factors which are system quality, service quality, and information quality were used. We verified the significance of the factors affecting the intension of continuous use. mainly, quality of information was considered as an important factor of continuous Intention to Use. Also, unlike previous NFC, it was found that in Non-NFC, compatibility might not be as important factor. Moreover, we suggest a marketing strategy of companies for mobile payment industry which focus on information quality. and future research directions for non NFC payment market.
