Recently, the spread of smartphones and various wearable devices has led to increases in the accumulation and usage of personal information. As a result, privacy protection has become an issue. Even though there have been studies and efforts to improve legal and technological security measures for protecting privacy, personal information leakage accidents still occur. Rather than privacy requirements, analysts mostly focus on the implementation of security technology within software development. Previous studies of security requirements strongly focused on supplementing the basic principles and laws for privacy protection and securing privacy requirements without understanding the relationship between privacy and security. As a result, personal information infringement occurs continuously despite the development of security technologies and the revision of the Personal Information Protection Act. Therefore, we need a method for eliciting privacy requirements based on related privacy protection laws that are applicable to software development. We also should clearly specify the relationship between privacy and security. This study aims to elicit privacy requirements and create privacy assurances cases for Privacy Friendly System development.

RFID is a widely adopted in the field of identification technology these days. Radio Frequency IDentification (RFID) has wide applications in many areas including manufacturing, healthcare, and transportation. Because limited resource RFID tags are used, various risks could threaten their abilities to provide essential services to users. A number of RFID protocols have done by researcher in order to protect against some malicious attacks and threat. Existing RFID protocols are able to resolve a number of security and privacy issues, but still unable to overcome other security & privacy related issues. In this paper, we analyses security schemes and vulnerability in RFID application. Considering this RFID security issues, we survey the security threats and open problems related to issues by means of information security and privacy. Neither a symmetric nor an asymmetric cryptographic deployment is necessarily used with light weighted algorithm in the future.

RFID technology can help automatically and remotely identify objects, which raises many security concerns. We review and categorize several RFID security and privacy solutions, and conclude that the most promising and low-cost approach currently attracts little academic attention. We therefore concluded that, from a privacy perspective, the user scheme is an important strategy for meeting the consumer's needs. Furthermore, we call for the privacy research community to put more effort into this line of thinking about RFID privacy.

Financial firms, especially large scaled firms such as KB bank, NH bank, Samsung Card, Hana SK Card, Hyundai Capital, Shinhan Card, etc. should be securely dealing with the personal financial information. Indeed, people have tended to believe that those big financial companies are relatively safer in terms of information security than typical small and medium sized firms in other industries. However, the recent incidents of personal information privacy invasion showed that this may not be true. Financial firms have increased the investment of information protection and security, and they are trying to prevent the information privacy invasion accidents by doing all the necessary efforts. This paper studies how effectively a financial firm will be able to avoid personal financial information privacy invasion that may be deliberately caused by internal staffs. Although there are several literatures relating to information security, to our knowledge, this is the first study to focus on the behavior of internal staffs. The big financial firms are doing variety of information security activities to protect personal information. This study is to confirm what types of such activities actually work well. The primary research model of this paper is based on Theory of Planned Behavior (TPB) that describes the rational choice of human behavior. Also, a variety of activities to protect the personal information of financial firms, especially credit card companies with the most customer information, were modeled by the four-step process Security Action Cycle (SAC) that Straub and Welke (1998) claimed. Through this proposed conceptual research model, we study whether information security activities of each step could suppress personal information abuse. Also, by measuring the morality of internal staffs, we checked whether the act of information privacy invasion caused by internal staff is in fact a serious criminal behavior or just a kind of unethical behavior. In addition, we also checked whether there was the cognition difference of the moral level between internal staffs and the customers. Research subjects were customer call center operators in one of the big credit card company. We have used multiple regression analysis. Our results showed that the punishment of the remedy activities, among the firm's information security activities, had the most obvious effects of preventing the information abuse (or privacy invasion) by internal staff. Somewhat effective tools were the prevention activities that limited the physical accessibility of non-authorities to the system of customers' personal information database. Some examples of the prevention activities are to make the procedure of access rights complex and to enhance security instrument. We also found that 'the unnecessary information searches out of work' as the behavior of information abuse occurred frequently by internal staffs. They perceived these behaviors somewhat minor criminal or just unethical action rather than a serious criminal behavior. Also, there existed the big cognition difference of the moral level between internal staffs and the public (customers). Based on the findings of our research, we should expect that this paper help practically to prevent privacy invasion and to protect personal information properly by raising the effectiveness of information security activities of finance firms. Also, we expect that our suggestions can be utilized to effectively improve personnel management and to cope with internal security threats in the overall information security management system.

Radio frequency identification (RFID) tags are cheap and simple devices that can store unique identification information and perform simple computation to keep better inventory of packages. Security protocol for RFID tags is needed to ensure privacy and authentication between each tag and their reader. In order to accomplish this, in this paper, we analyzed a lightweight privacy and authentication protocol for passive RFID tags.

In this paper, we evaluated web security vulnerability and privacy information management of hospital web sites which are registered at the Korea Hospital Association. Vulnerability Scanner (WVS) based on the OWASP Top 10 was used to evaluate the web security vulnerability of the web sites. And to evaluate the privacy information management, we used ten rules which were based on guidelines for protecting privacy information on web sites. From the results of the evaluation, we discovered tertiary hospitals had relatively excellent web security compared to other type of hospitals. But all the hospital types had not only high level vulnerabilities but also the other level of vulnerabilities. Additionally, 97% of the hospital web sites had a certain level of vulnerability, so a security inspection is needed to secure the web sites. We discovered a few SQL Injection and XSS vulnerabilities in the web sites of tertiary hospitals. However, these are very critical vulnerabilities, so all hospital types have to be inspected to protect their web sites against attacks from hacker. On the other hand, the inspection results of the tertiary hospitals for privacy information management had a better compliance rate than that of the other hospital types.

Radio Frequency Identification system based on EPC(Electronic Product Code) Network Environment can read or write information of tagged objects, using Rf signals without direct contact. This advantage which is to provide storage ability and contactless property is better than Bar-code system. Mobile RFID system which integrates Mobile system with RFID system will provide new additional service to users. However, an advantage for obtaining information of objects using RF signal causes personal privacy problem. In this paper, we propose techniques that can protect personal privacy based on mobile. Our scheme provides privacy protection of users and is more efficiently than another application service.

Mobile Crowdsourcing (MCS) has become an emerging paradigm evolved from crowdsourcing by employing advanced features of mobile devices such as smartphones to perform more complicated, especially spatial tasks. One of the key procedures in MCS is to collect answers from mobile users (workers), which may face several security issues. First, authentication is required to ensure that answers are from authorized workers. In addition, MCS tasks are usually location-dependent, so the collected answers could disclose workers' location privacy, which may discourage workers to participate in the tasks. Finally, the overhead occurred by authentication and privacy protection should be minimized since mobile devices are resource-constrained. Considering all the above concerns, in this paper, we propose a lightweight and privacy-preserving answer collection scheme for MCS. In the proposed scheme, we achieve anonymous authentication based on traceable ring signature, which provides authentication, anonymity, as well as traceability by enabling malicious workers tracing. In order to balance user location privacy and data availability, we propose a new concept named current location privacy, which means the location of the worker cannot be disclosed to anyone until a specified time. Since the leakage of current location will seriously threaten workers' personal safety, causing such as absence or presence disclosure attacks, it is necessary to pay attention to the current location privacy of workers in MCS. We encrypt the collected answers based on timed-release encryption, ensuring the secure transmission and high availability of data, as well as preserving the current location privacy of workers. Finally, we analyze the security and performance of the proposed scheme. The experimental results show that the computation costs of a worker depend on the number of ring signature members, which indicates the flexibility for a worker to choose an appropriate size of the group under considerations of privacy and efficiency.
