The data wiping is a technique which perfectly deletes data in a storage to prevent data recovery. Currently, management of stored data is important because of increasing an accident of personal information leakage. Especially, if you need to discard data contained personal information, using a wiping tool which permanently deletes data to prevent unnecessary personal information leakage. The data wiping is also used for data security and privacy protection. However the data wiping can be used intentionally destruction of evidence. This intentionally destruction of evidence is important clues of forensic investigation. This paper demonstrates the methods for detecting the usage of wiping tools in digital forensic investigation.

Today, with the popularity of smart phones and the proliferation of SNS, anyone is exposed to the risk of personal information leakage. Unlike the prior studies of privacy, this research aims to identify the privacy factors affecting the provision intention of individual information from the SNS Users. This study also analyses how the perceived privacy risks and corporate trust affect the provision intention of individual information. The analysis results of empirical data show that despite experiencing the privacy leakage such as direct hacking and being aware of the risk, people are providing firms with personal information. The most influential variables to perceived privacy risk are information privacy policy, information privacy concern, previous privacy experience and information privacy awareness in the decreasing order of importance. Those to the corporate trust are information privacy policy, information privacy awareness, previous privacy concern and information privacy experience. Besides, the corporate trust and the perceived privacy risk also affect the provision intention of personal information. Finally, this study proposes the implications for personal information privacy.

Due to the development of ICT, with using hardwares such as WiFi, 3G and GPS and so on, smartphone could have provided a lot of applications with novel functions rapidly. Through such applications, lots of personal information such as personal location, personal images, and list of phone calls is created, saved and widely used. Because there is lots of leakage of the stored personal information due to loss of phone and application, privacy violation have been important issue nowadays. Smartphone with GPS and Internet provides location information. To protect the information, the technologies that only the authorized user can access it while inquiring the location information have been proposed. In this paper, to minimize the identification information for location information subject and information user and anonymize the identifiable information such as phone number, we proposed a model that can reduce the leakage of information and avoid the wrong usage of the stored information in the server. This technique will be used for protecting privacy when developing the application that provides routing service through location history information.

In this paper, we analyze the quality status of Health and Welfare division's standardized log and asses the characteristics of the institutions' logs analysis to establish the criteria to minimize hazards and control the quality of log's institutional details to limit extraction. As a result, extraction condition's proposed development direction to adequately assess and control health and welfare abuses privacy control target log. This improvement over the status and quality of information shared with relation to institutional work of the log quality characteristics is made possible. In addition, quality control and inspection standards were prepared in accordance with the institutional log characteristics. Future research will include performing continuous analysis and improvement activities on the quality of logs with integrated control of sharing personal information and distributing information about logs' quality to proactively target organ. Therefore, we expect that correcting proactive personal information misuse and leakage is possible to achieve.

With the development of the Internet, user authentication technology that proves me online is improving. Existing ID methods pose a threat of personal information leakage if the service provider manages personal information and security is weak, and the information subject is to the service provider. In this study, as online identification technology develops, we propose a DID-based self-authentication model to prevent the threat of leakage of personal information from a centralized format and strengthen sovereignty. The proposed model allows users to directly manage personal information and strengthen their sovereignty over information topics through VC issued by the issuing agency. As a research method, a self-authentication model that guarantees security and integrity is presented using a decentralized identifier method based on distributed ledger technology, and the security of the attack method is analyzed. Because it authenticates through DID Auth using public key encryption algorithms, it is safe from sniffing, man in the middle attack, and the proposed model can replace real identity card.

The Internet is referred as sea of information, which provides huge information, but personal information is collected for malicious behavior and provided to various web sites via internet. This can lead to economic losses as well as the disclosure of personal information. We can easily get personal information from device, such as mobile and private terminal, as well as internet, and then it can be spread very quickly. The personal information leakage and damage cases are also increasing, while the importance of personal information on the web page to distinguish the individual as the basic information is growing. In this paper we review and analyse recent invasion of privacy practices on the web and its causes, and technical and administrative protections.

DID(Decentralized Identity Identification) is a system in which users voluntarily manage their identity, etc., and control the scope and subject of submission of identity information based on a block chain. In the era of the 4th industrial revolution, where the importance of protecting personal information is increasing day by day, DID will surely be positioned as the industrial center of the Internet and e-business. However, when managing personal information, DID is highly likely to cause a large amount of personal information leakage due to electronic infringement, such as hacking and invasion of privacy caused by the concentration of user's identity information on global service users. Therefore, there are a number of challenges to be solved before DID settles into a stable standardization. Therefore, in this paper, we try to examine what problems exist in order to positively apply the development of DID technology, and analyze the improvement plan to become a stable service in the future.
