E.U(Europe Union) and I.S.O(International Standard Organization) have promoted environmental problems from an individual enterprise level to international level. E.U have practiced E.M.A.S(Environment Management Audit Scheme), they have explained environmental information to local residents by an environmental statement and they have introduced verification system by identification person. One year later, I.S.O have published ISO 14000 series by environmental audit in 1996. Modem enterprise must go well with profitability and sociality. Environmental accounting was appeared in order to agree with profitability and sociality. Environmental accounting is to solve environmental problems, to protect natural resources, to measure effect of environment, and to transmit information of environment. Accountability's theory must be based social fairness and systemic legality. We need the accountability in order to system of Environmental accounting. But the conception of environmental accounting and accountability are not defined in our country. Therefore the purpose of this study is to established the relation of environmental accounting and accountability.

In an IPTV system, the rights of the content and service provider can be protected by using Conditional Access System (CAS) and Digital Right Management (DRM). In case of the CAS, only the authorized user who has structured authentication keys can decrypt the encrypted content. However, since the CAS establishes a secure channel only between content provider and Smart Card (SC), it cannot protect the system against McCormac Hack attack which eavesdrops on unsecure channel between SC and Set-Top Box (STB) and SC cloning attack. In this paper, we propose a robust multi-STB assisted SC / STB authentication protocol which can protect the IPTV system against not only McCormac Hack attack, but also SC cloning attack. The previous works which bind a STB and a SC during the SC registration phase against the SC cloning attack does not support multi-STB environments. The proposed system which dynamically updates the STB information in subscriber management system using the bi-directional channel characteristic of IPTV system can support the user's multi-STB device effectively.

With the spread of computer and development of internet service, the varied contents and digital data has been produced, then provided. The digital contents are more efficiently able to be created, produced, provided as well as distributed, on the other hand, its own copyrights seem to be more easily broken than analogue contents due to the convenience to make copies of original contents. Therefore, protecting copyrights recently become the key issue. DRM(Digital Rights Management) is the current technology to protect digital contents from duplication but it sometimes causes problems in the key-management. In this thesis, we would first like to analyze DRM and find out some trouble in the key-management of it. Finally, we will show CDMS(CEK Distributed Management System) to improve DRM out of the key-management problem and continue to study for better key-management system with it.

Infringement of information security has caused the corporate image to be damaged and share price to fall, and it is emerging as an organizational risk. The value of information assets in enterprises has led to a higher level of security than in the past. As a result, companies are aware of the need for officers to protect information and to oversee a security management system. However, despite the growing importance of information security officers, there is a lack of research on their roles and characteristics. This study validates the relationship between determinants that affect the performance of information security. And a structural equation model was presented and empirically analyzed to see the impact of the internal and external characteristics of the staff in charge of information security on the organization's information security performance.

There are some problems on the system that uses a password comprising a digital signature to identify the secret key owner under the public key infrastructure. For example, the password can be difficult to remember or easy to be disclosure, and users should make more complex password to protect it. A number of studies have been proceeded in order to overcome these defects using the fingerprint identification technologies, but they need to change the current standard of public key infrastructure. On the suggested private key escrow system, the private key can be withdrawn only through the enrollment and identification of a fingerprint template after it is saved to a reliable third system. Therefore, this new private key escrow system can remove previous inconveniences of managingthe private key on current public key infrastructure, and it exhibited superior results in terms of the evaluation items when compared with the integrated method of the existing fingerprint identification and public key infrastructure.

The system proposed in this paper is a fully automated parking control system that can even protect users' information through blockchain. Unlike conventional parking control systems, the system consists of a web page that is accessible to people of all ages and ages, directly to the parking lot. Such a system would also benefit managers in the parking lot business. This is because it can reduce soaring labor costs and maximize the sales it can generate by operating 24 hours a day. In order to implement these systems, the web page was first designed using HTML and the API was configured using JAX-RS to invoke the API required by the web page. As a result, it created a web page that was easily accessible to anyone, built a server that could be accessed by more than 200 people at the same time, focused on personal information protection by encrypting the information of users through blockchain grafts, and designed a system that enabled users to complete payments easily. It is planning to add QR codes and GPS functions in the future and implement a function that allows one-touch information on parking lots and their vehicle information.
