Térfigyelő kamerarendszerek általános rendszerkövetelményei Fehér András Az IP kamera technológia felgyorsult fejlődése, az internet hálózatok sávszélességének növekedése, valamint az arcfelismerő biometrikus algoritmusok azonosítási képességének javulása együttesen járulnak hozzá az arcfelismerési funkcióval kiegészített, vagy azt nem tartalmazó térfigyelő kamerarendszerek térhódításához. E megoldások terjedése a technika fejlődésével párhuzamosan indult, azonban a bostoni robbantásokat követően felgyorsult. Külön aktualitást a kérdésnek a már Európa szerte is megszaporodó robbantásos merényletek adnak. Egyre gyakrabban merül fel akár hatóságok, akár polgári megrendelők részéről egy olyan általános rendszerkövetelmény kidolgozása, mely betartása esetén garantálható az elvárt eredmény. Jelen cikkben foglalkozom e – amúgy jogosnak tekinthető – igény teljesíthetőségének műszaki és technológiai korlátaival.

A right to privacy as a fundamental human right in correlation with data protection Ivona Ninkov This paper presents a general overview of the rights to privacy as a fundamental human right in the correlation with data protection. The paper aims to illustrate how rights of privacy are developed after the Second World War and the data protection regulation after the case of Snowdan. It clarifies the difference between the right to privacy and data protection in the lights of the General Data Protection Regulation, which entered into force on May 25th, 2018. The paper outlines data protection terminology, people’s rights and how these rights are enforced through international legal treaties. During the research the author used a comparative method to find the similarity and differencies between the privacy rights and personal data protection focusing on the rich jurisprudence of the European Court of Human Rights (ECtHR) and the Court of Justice of the European Union (CJEU). In the paper it is concluded that the right of privacy and the right of personal data protection are closely linked, but they should not be considered to be identical.

Applying Information Security Risk Management Standards Process for Automated Vehicles Malak M. Shatnawi Development of the transportation system is the main concern for each country, it provides a continual flow of goods, services and information’s essential for the economic, security, safety, welfare, and to the health of its citizens. Transportation generally framed as a key component for progress, the sustainability dimensions represented by the social, economic, and environmental pillars have direct impacts on the cities and regions growth and prosperity which become the main challenge for all researchers and engineers because of the expansion of transportation networks. The rapid modern technology brought changes in all fields including road transportation and infrastructure and one of the most contemporary research subjects in transportation is the Automated Vehicles AV or Self Driven Vehicles SDV. The main challenges in the field of autonomous vehicles rest in the fact of improving road safety, minimizing accidents and human errors. It is known that road safety is a difficult issue including several fields to study such as human, vehicles, roads and socio-economic and environment factors. This paper will focus in transportation, infrastructure and mobility risk management which seeks to make transportation system more efficient in term of safety, security, traffic accidents, security of data and information technology as well as software systems against malfunctions and all kinds of attacks. The aim of the paper is to discuss the challenges and threats faced in the development of the autonomous vehicles AV by studding information security risk management standard process, and explaining how applying the process of International Organization for Standardization (ISO), the concept of applying ISO 27005, to AV will be discussed here through certain processes.

Geometric design of sleeve and abutment for subperiosteal implants using finite element analysis Kulcsár Klaudia; Kónya János Nowadays, we experience a rapid development is the field of implantology. Dental implant insertion became a routine procedure during which, mostly screw-type implants are used. Achievements in modern implantology result in such tooth replacements which are perfectly identical to natural teeth both aesthetically and functionally. Thus, chewing ability can be completely restored. The most important advantage of these procedures is that they prevent further bone resorption in neighbouring tissues. The use of custom-made implants becomes even more widespread in modern implantology. Thanks to the patient-specific design, various dental replacements are made that fulfil different needs and expectations of each patient. The creation of these custom design implants is carried out with additive manufacturing technology. This additive technology provides an opportunity for patients who have insufficient bone tissue for the insertion of conical implants. This study presents denture-supporting abutments of different geometric designs. The abutment is directly connected to the sleeve, which is fixed to the subperiosteal implant with micro-welding technology. In geometric design, the distribution of axial forces resultant from the denture is of vital importance as stress levels should be decreased. Examinations were carried out with finite element analysis, which is a widely-used method in engineering practice. By the end of this study, optimal geometric design is determined by comparing the result of each design. The chosen geometry is then implemented into practice and used for the implantation procedure. The material of choice for the subperiosteal implant is Grade 23 titanium alloy, and it is created with an additive manufacturing process. The material of the sleeve and abutment is Grade 5 titanium alloy, and these parts are manufactured with a subtractive process.
