Recently, with the development of biotechnology and molecular genetics, research using human biological materials has been receiving attention, and the demand for the use of human- biological materials has also increased significantly. In particular, human biological materials contain the personal information of the person providing them, so special care must be taken to protect personal information throughout the entire process from drafting the human biological materials research plan, Institutional Review Board (IRB) review, and research progress. In addition, it is important to appropriately utilize residual human biological materials obtained during medical diagnosis and treatment at medical institutions to achieve scientific results, while protecting the rights of human biological materials providers and improving the method of expressing consent so as not to damage the trust of human biological materials providers in researchers. To this end, it is necessary to provide sufficient information and education so that researchers and IRB members can understand and apply related laws such as the Bioethics Act and the Personal Information Protection Act.

Recently the use of personal mobility devices is rapidly increasing, and the businesses related to personal mobility devices are quickly growing as well. Although the use of personal mobility devices provides convenience for short distance movements, many problems occur due to the lack of safety devices and the absence of associated road traffic laws. The number of accidents caused by using personal mobility devices continues increasing every year, and the injuries or deaths are seriously happening with those accidents. When using personal mobility devices, there are basic safety precautions such as wearing a helmet, prohibiting boarding with more than two people, prohibiting boarding with more than 100kg, prohibiting using after drinking alcohol, and so on. However, it is exposed to traffic accidents because there is no way to check before using the system. Therefore, to ensure the user's safety in using the electric kickboard among personal mobility devices, this paper proposes a system that can check the user's safety state before using the electric kickboard. It is possible to safely use personal mobility devices and prevent accidents by proposing a system structure of the electric kickboard that can be used after checking for the use of more than two people, overweight, wearing a helmet, and drinking alcohol.

This study analysed the legal concept of personal information(PI), which was not differentiated from behavioral information, and established it clearly for invigorating online targeted advertising(OTA), which draw attention in big data era; by selecting Guidelines of Assessment of Data Breach Incident Factors and Guidelines of Measures for No-Identifying Personal Information based on Personal Information Protection Act(PIPA) and Enforcement Decree of the PIPA. As a result, PI was defined as any kind of information relating to (1)a living individual(not group, corporate body or things etc.); (2)makes possibly identify the individual by his or her identifiers such as name, resident registration number, image, etc. (not included if not identify the individual); and (3)including information like attribute values which makes possibly identify any specific individual, if not by itself, but combined with other information which can be actually collected and combined). Specifically, PI includes basic, proper distinguishable, sensitive and other PI. It is suggested that PI concept should be researched continually with digital technology development; the effectiveness of the Guidelines of PI Protection in OTA, the legal principles of PI protection from not only users' but business operators' perspectives and the differentiation between PI and behavioral information in OTA should be researched.

This study intended to identify dental hygienists' knowledge and extent of awareness and performance of patient's personal information protection. In addition, this research was conducted to contribute to medical centers' preparation of measures to strengthen the personal information protection by identifying the factors affecting dental hygienists' extent of performance related to the patient's personal information protection. After explaining the purpose and meaning of the research to the survey participants and gaining their consent, a self-administered survey was conducted from November 7, 2014 to June 30, 2015. The data on 210 dental hygienists in Busan city and Gyeongsangnam-do province was used for analysis. As a result, in dental hygienists with more than 10 years experience, the extent of the performance was significantly high (p<.05). In positions higher than a senior manager, the extent of knowledge was high (p<.01) and the extent of performance was significantly high (p<.05). In hospitals with more than 10 to 20 workers, the extent of awareness was significantly high (p<.05). Regarding the correlation of knowledge and the extent of awareness and performance, a high level of knowledge showed a positive correlation of the extent of awareness and performance (p<.01). As a result of a survey regarding what effects dental hygienists' knowledge and extent of awareness of patient's personal information protection have on dental hygienists' extent of performance, it was found that knowledge (.231) and the extent of awareness (.212) are factors affecting the extent of performance. Therefore, to increase the extent of dental hygienists' performance of patient's personal information protection, there is a need to improve the knowledge of patient's personal information protection and change its awareness. To change the awareness of patient's personal information protection, there is a serious need to carry out education targeting dental hygienists.

As the utilize of personal health records increases in recent years, research on cryptographic protocol for protecting personal information of personal health records has been actively conducted. Currently, personal health records are commonly encrypted and outsourced to the cloud. However, this method is limited in verifying the integrity of personal health records, and there is a problem with poor data availability because it is essential to use it in decryption. To solve this problem, this paper proposes a verifiable cloud-based personal health record management scheme using Redactable signature scheme and zero-knowledge proof. Verifiable cloud-based personal health record management scheme can be used to verify the integrity of the original document while preserving privacy by deleting sensitive information by using Redactable signature scheme, and to verify that the redacted document has not been deleted or modified except for the deleted part of the original document by using the zero-knowledge proof. In addition, it is designed to increase the availability of data than the existing management schemes by designing to recover deleted parts only when necessary through the Redact Recovery Authority. And we propose a verifiable cloud-based personal health record management model using the proposed scheme, and analysed its efficiency by implementing the proposed scheme.

The importance of personal data protection is increasingly emphasized both at home and abroad, and while overseas countries are applying various policies and dynamic management technologies, there are some gaps between compliance with laws and regulations and the application of technologies in Korea, and there are few user interfaces that provide convenient ways for data subjects to stop processing personal data. This study first analyzes the need for dynamic personal information consent management technology, the current state of the industry, and the prospects for its development. Next, this study proposes a basic model for dynamic management of personal information consent that maximizes the data subject's right to personal data self-determination while strictly complying with personal data protection laws in Republic of Korea. In particular, this study analyzes the basis of domestic laws and regulations related to the suspension of personal data processing, designs a basic model of personal data consent dynamic management interface, and presents its effectiveness. Based on the results of this study, we expect that the proposed dynamic management model for personal data use consent can be used in various ways for various websites and applications in the future.

To survive in the trend of the fourth industrial revolution, companies are putting a lot of attention and effort into personalization services using the latest technologies such as big data, artificial intelligence and the Internet of Things, while entrusting third parties to handle personal information on the grounds of work efficiency, expertise and cost reduction. In such an environment, consignors need to check trustees on a more effective and reasonable basis to ensure personal information safety for trustees. This study used AHP techniques to derive the importance and priority of each item of "Personal Information Safety Assurance Measures" for financial companies and trustees, and objectively compared and analyzed differences in perceptions of importance between financial institutions and trustees. Based on this, the company recognizes the difference between self-inspection of financial institutions and inspection of trustees and presents policy grounds and implications for applying differentiated inspection standards that reflect the weights appropriate for the purpose.
