Recent dramatical development of computer technology related to internet technology intensifies the dispute over software of computer or smart device. Research on software has been flourished with political issuing of fierce competition among nations for software development. Particularly industrial growth in ethernet based big data and IoT (Internet of Things) has promoted to build and develop open source programs based on java, xcode and C. On these circumstances, issue on software piracy has been confronted despite the basic security policy protecting intellectual property rights of software and thus it is of substantial importance to protect the rights of originality of source program license. However, the other issue on source technology protection of developer is the possibility of hindrance to advancement in industry and culture by developing programs. This study discuss the way of enhancing legal stability of IoT application program development and reinforcing precision in inspection of program plagiarism by analyzing the source programs with newly introducing text mining technique, thus suggests an alternative protective way of infringement of personal information due to duplicating program.

In a rapidly changing IT and business management environment the demand for competent IS personnels is increasing. However, it is ironic that the number of IT and IS majors has sharply decreased as well as the widespread skepticism of IS identity. This research suggests directions to differentiate MIS to other IT majors, diversify IS core competency and make general improvements in MIS curriculum. The research recommend the courses of IS Strategy and policy, ITA/EA, Global IT Management, Emerging Technologies, DW/DM, BI, IT Service Science, Project Management, IT Consulting and integrated capstone which are few in Kore universities. This research also stress the course of soft skills like business communication, team building, analytic/logical thinking, rational problem solving and so on as a important IS competency. The pedagogy of course is important, so the research recommend the internship, mentoring programme, lecturers in industry according to industrial - educational cooperation.

Based on the 'Government 3.0', the government opens the public data and encourages the active use in the private sector. Recently, the spatial and statistical information that is one of the public data is being widely used in the various web business as a high value-added information. In this study, we propose an architecture of high-availability, high-reliability and high-performance open platform which can provide a variety of services such as searching, analysis, data mining, and thematic mapping. In particular, we present two different system architectures for the government and the public services, by reflecting the importance of the information security and the respective utilization in the private and public sectors. We also compared a variety of server architecture configurations such as a clustered server configuration, a cloud-based virtual server configuration, and a CDN server configuration, in order to design a cost- and performance-effective spatial-statistical information open platform.

With widespread use of the Internet and improvements in streaming media and compression technology, digital music, video, and image can be distributed instantaneously across the Internet to end-users. However, most conventional Digital Right Management are often not secure and not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. The SVC offers temporal, spatial, and SNR scalability to varying network bandwidth and different application needs. Meanwhile, for many multimedia services, security is an important component to restrict unauthorized content access and distribution. This suggests the need for new cryptography system implementations that can operate at SVC. In this paper, we propose a new scrambling encryption for reserving the characteristic of scalability in MPEG4-SVC. In the base layer, the proposed algorithm is applied and performed the selective scambling. And it encrypts various MVS and intra-mode scrambling in the enhancement layer. In the decryption, it decrypts each encrypted layers by using another encrypted keys. Throughout the experimental results, the proposed algorithms have low complexity in encryption and the robustness of communication errors.

A threshold decryption scheme is a multi-party public key cryptosystem that allows any sufficiently large subset of participants to decrypt a ciphertext, but disallows the decryption otherwise. When performing a threshold decryption, a third party is often involved to guarantee fairness among the participants. To maintain the security of the protocol as high as possible, it is desirable to lower the level of trust and the amount of information given to the third party. In this paper, we present a threshold decryption scheme which allows the anonymity of the participants as well as the fairness by employing a semi-trusted third party (STTP) which follows the protocol properly with the exception that it keeps a record of all its intermediate computations. Our solution preserves the security and fairness of the previous scheme and reveals no information about the identities of the participants and the plaintext even though an attacker is allowed to access the storage of the STTP.

As the number of recent information security incident occurrence increases, more and more workload and liability pressure are given to info-security professionals, which results in decrease of morale level of working groups in the field. In order to solve this problem, Korean government is providing various action plans to improve the morale level of info-security professionals, and also requiring financial companies to submit its own action plan of increasing morale of info-security professionals to Financial Service Agency. For this study, based on the previous studies and relevant professionals' interviews, we selected 16 critical morale increase variables, and performed survey for empirical analysis. As a result, 3 features; role, system, and relationship were presented as the main factor of morale increasement of info-security professionals. This study also suggests a decision making method of utilizing the developed morale measurement model for individual organizations.

With a great improvement of computers and Network communication skills, we can exchange information quickly. There have been many researches on the subject how to guarantee the information security by security mechanism and cryptography schemes. Nowadays, many people in this area show their interest in money transfer systems between accounts, which can provide a secure mechanism in which people can send money to the legitimate party or person safe. However, we have teamed many ways to distort messages and repudiate the malicious activity in mail systems based on SSL mechanism. It is very likely that important information which must be kept in secret is laid exposed to un_authorized user. Accordingly, to provide stronger security service, researches on electronic payment system which tan guarantee the security characteristics such as confidentiality, integrity, user authentication, Non-repudiation, are strongly needed. In this paper, we analize the characteristics of the previous researches in this field, and also propose a securer electronic payment system based on ECC algorithm.
