  • IDS/IPS and networked computer systems are playing an increasingly important role in our society. They have been the targets of a malicious attacks that actually turn into intrusions. That is why computer security has become an important concern for network administrators. Recently, various Detection/Prevention System schemes have been proposed based on various technologies. However, the techniques, which have been applied in many systems is useful for existing intrusion patterns on standard-only systems. Therefore, probe detection of private clouds using BlockChain has become a major security protection technology to detection potential attacks. In addition, BlockChain and Probe detection need to take into account the relationship between the various factors. We should develop a new probe detection technology that uses BlockChain to fine new pattern detection probes in cloud service security in the end. In this paper, we propose a probe detection using Fuzzy Cognitive Map(FCM) and Self Adaptive Module(SAM) based on service security using BlockChain technology.

  • This paper attempted to examine to what extent advertising as expression has been constitutionally protected through an analysis on the reputational-right-related legal cases. In order to make the understanding more clearly, this paper applied Van Alstyne's graphical depiction on how commercial speech is protected compared with other constitutional rights such as political speech, private expression, defamation, and obscene expression. Through the analysis, this paper found out that first, in the legal cases, there has been no consideration on whether the status of the plaintiff is public figure or private figure, whereas in the libel cases, Korean courts has made a distinction between public figure and private figure since 2002; second, when the case is concerned with corporations, the Korean courts do not give consideration on the status of corporation, while the status of corporation is a somewhat important factor in deciding the degree of responsibility in the U.S.; third, even though it is clear that advertising in Korea is being protected as expression, it is nebulous whether it is well balanced with other personal rights that are constitutionally protected. Conclusively, applying the Alstyne's graphical depiction on Korean advertising, it advertising as expression in Korea is being provided lower protection than defamation. To put it differently, like the case in the U.S., advertising, although it is allegedly protected as expression, does not yet enjoy full-fledged constitutional protection in Korean society. Rather, there must be some actions to be taken to enhance the degree of protection of advertising.

  • Private set intersection cardinality (PSI-CA) is a typical problem in the field of secure multi-party computation, which enables two parties calculate the cardinality of intersection securely without revealing any information about their sets. And it is suitable for private data protection scenarios where only the cardinality of the set intersection needs to be calculated. However, most of the currently available PSI-CA protocols only meet the security under the semi-honest model and can't resist the malicious behaviors of participants. To solve the problems above, by the application of the variant of Elgamal cryptography and Bloom filter, we propose an efficient PSI-CA protocol with high security. We also present two new operations on Bloom filter called IBF and BIBF, which could further enhance the safety of private data. Using zero-knowledge proof to ensure the safety under malicious adversary model. Moreover, in order to minimize the error in the results caused by the false positive problem, we use Garbled Bloom Filter and key-value pair packing creatively and present an improved PSI-CA protocol. Through experimental comparison with several existing representative protocols, our protocol runs with linear time complexity and more excellent characters, which is more suitable for practical application scenarios.

  • Objectives: This study was conducted to investigate the effect of professional self-concept and ethical awareness of dental hygiene (department) students attending a university located in Gwangju and Jeollanam-do on patients' willingness to protect personal information. Methods: Professional self-concept, ethical disposition, and patients' personal information protection intention according to general characteristics were analyzed using t-tests and one-way ANOVA. After confirming the correlation through Pearson's correlation analysis, the effect on the patient's personal information protection intention was confirmed using multiple regression analysis. Results: Professional self-concept, ethical disposition, and the patients' willingness to protect personal information all showed positive correlations. The higher the communication skills of professional self-concept and the higher the idealism of ethical orientation, the higher the patients' willingness to protect personal information. Conclusions: This study, ascertained the effect of dental hygiene students' professional self-concept and ethical consciousness on patients' personal information protection practices. The results suggest that it is necessary to develop an educational program that can enhance the practice of dental hygienists to protect patients' personal information, and to develop and conduct continuous policy development and research.

  • The system specification is a system theory based formal representation method for systems' structure and behavior modeling. When we make use of the system specification method in each step of software development, we can derive a hierarchical and modularized system design which enables us to manage the software development process flexibly. This research presents system specification based design of a mobile alarm system which sends alerts about illegal usage of private information and manages the response against the each alert. In our design of mobile alarm system, there are formal definition of alert message overcoming the functional limitation of mobile device and hierarchical modularized modeling of alarm processing using system specification. The efficiency of making use of the system specification is shown by applying the specification method to implementation of mobile alarm system. The contribution of this work is in design and implementation of mobile alarm system which enables us to handle the private information leakage situation more flexible way using system specification based software designing method.

  • Mobile RFID system is a next generation technology which combines the existing RFID systems with mobile systems. It is newly expected to provide additional services and will be broadly used in everyday life; however, it sometimes causes the privacy or security problems generated by existing RFID systems and the additional privacy or security problems. Moreover, even if many methods have been proposed to solve those problems, it is still difficult to adapt to reality or to guarantee the security perfectly. Therefore, in this paper, we propose the secure and practicable privacy protection mechanism suitable to mobile RFID systems. proposing mechanism is applicable the mechanism to Private Zone of mobile RFID systems which require to protect the privacy. This mechanism suggests that own tagging-products needed to protect privacy using mobile reader of personal don't provide any information to other readers except their own reader. In addition to, proposing mechanism is the efficient mechanism which largely reduces the process to maintain the synchronization when happen to the DoS attack or system error.

  • Digital watermarking has gained importance in recent years in copyright protection and multimedia. This paper proposes a secure and novel watermarking system based on complemented Maximum Length Cellular Automata (MLCA) and Two-Dimension Cellular Automata Transform (2D CAT). In this watermarking scheme, the original watermark is first encrypted by complemented MLCA with the private keys, and then the encrypted watermark is embedded into the CAT domain of the cover image, at last use the inverse CAT for the transformed image, the watermarked image is obtained. Experiment results show that this new method is more secure and provides robust performance against watermarking attacks.
