Pharming attack is a confidence trick that the hacker catch away customers financial information on Internet banking. At first, a hacker installs malicious execution code on customers PC in secret. As a customer tries to connect a Internet banking Web site, the malicious code changes it to phishing site in Internet explorer. The hacker catch away customers financial information in process of internet banking. The hacker steals money from customer's bank account using stolen information. PKI is a widespread and strong technology for providing the security using public key techniques. The main idea of PKI is the digital certificate that is a digitally signed statement binding an user's identity information and his public key. The Internet banking service stands on the basis of PKI. However, the bank is trusted in natural, the only customer is certified in the present Internet banking. In this paper, we propose a method of cross certification in Internet banking. The customer certify a bank and the bank certify the customer in proposed method. The method can service to customer the secure Internet banking about pharming attack. We compare the proposed method with other methods.

Today, wearable technology products are used in a wide range of consumer, healthcare, bio-medical, and industrial applications. The market for wearable technology products is expected to increase dramatically over the next several years. In addition, concerns for safety, performance and reliability of wearable products keep increasing and will be essential for widespread acceptance in the marketplace. Wearable smart devices, which are generally in contact with the human body and skin, are exposed to the risk of the electric shock, burn, and explosion. Therefore, the standardization of wearable devices in terms of human safety and reliability should be very important. Furthermore, the development of test method and test certification of the wearable products will be one of the key technology for mass production. Such standardization and certification will help consumers to choose the safest and best quality wearable devices and allow manufacturers to prove the safety and quality of their products, thereby helping them to gain a competitive technology. This paper discusses the current status of the wearable smart devices as well as the standardization and test certification applicable to wearable technology products.

This short review was aimed to provide the information for the people who are interested in genetic counselor education and certification system in Korea. A large part of this study is indebted to HJ Kim's articles on the genetic counselor system, the global standards of genetic counseling curriculums, training program accreditation (TPA), and a certification process for genetic counselors (CPGC) in the US and Japan. The US and Japanese educational systems showed a high degree of similarities in curriculum, accreditation, and certification programs. Based upon this review, we hereby propose that the Korean Society for Medical Genetics should take a key role in providing the TPA and CPGC for non-MD genetic counselors. Requirement for the entrance to a Master's degree genetic counseling program should be open to successful four year undergraduate students for all areas, provided the candidates demonstrate the abilities to master the graduate level study in human genetics, statistics, psychology, and other required subjects. Besides accredited program graduates, eligibility for certification should also include the qualified candidates of genetic counseling with no formally approved education, but with a sufficient amount of clinical experience.

Purpose: Autonomous driving cars, which are often represent the new convergence product, have been researched since the early years of 1900 but their safety assurance policies are yet to be implemented for real world practices. The primary purpose of this paper is to propose a modular concept based on which a safety assurance system can be designed and implemented for operating autonomous driving cars. Methods: We combine a set of key attributes of CE mark (European Assurance standard), E-Mark (Automobile safety assurance system), and A-SPICE (Automobile software assurance standard) into a modular approach. Results: Autonomous vehicles are emphasizing software safety, but there is no integrated safety certification standard for products and software. As such, there is complexity in the product and software safety certification process during the development phase. Using the concept of module, we were able to come up with an integrated safety certification system of product and software for practical uses in the future. Conclusion: Through the modular concept, both international and domestic standards policy stakeholders are expected to consider a new structure that can help the autonomous driving industries expedite their commercialization for the technology advanced market in the era of Industry 4.0.

Unmanned Aircraft Systems (UAS) are rapidly emerging not only as a key military power, such as surveillance and reconnaissance for military purposes but also as a new air transportation means in the form of Urban Air Mobility (UAM). Currently, airworthiness certification is carried out focused on the verification of technical standards for flight safety suitability of aircraft design in accordance with the Military Aircraft Flight Safety Certification Act and does not employ the model for operational risk assessment for mission areas and airspace. In this study, in order to evaluate the risk of the mission area from the perspective of the UAS operator, a risk assessment simulation has been conducted by applying the Specific Operations Risk Assessment (SORA) model to the operating environment of the Korean military UAS. Also, the validity of the SORA model has been verified through the analysis of simulation results, and a new application plan for airworthiness certification of the military unmanned aerial system has been presented.

PGP is an encryption software designed to provide information protection, security and authentication services for online communication systems. The characteristic of behavior done on the Internet is that you don't know the other person. It is very important to protect information from someone you cannot trust. So identification of the other person is an important task. PGP uses an digital signature algorithm to verify the identity of the other party. However, it is not accurate to check the other party's credibility. PGP increases trust as other users sign more on public keys of user. In other words, credibility is not perfect. In this paper, PGP certification system that key management in Ethereum blockchain, one of the blockchain platforms, is proposed. Key management in blockchain ensures data integrity, transparency and reliability.

A major effect of electronic commerce on the Internet is that it reduces transaction costs and creates an efficient market. Thus, an information strategy for developing of regional economy must be changed toward 21st century of electronic commerce era. In this paper, we present an information strategy for activating the electronic commerce of regional small and medium-sized business organizations. The paper stresses creation of a network organization comprising local government, regional business organizations, universities, research institutes, and citizens' coalitions as groups of organizational actors. Necessary conditions of a successful network organization in electronic commerce are to build the public key infrastructure for developing the trust of transactions among partners, and to create an information center to manage a web of partners. In the network organization, the information center must play critical roles as a creator of value and the certification authority in order to issue and manage participants' electronic certificates.
