摘要： This paper applies depth images and a 3D simulation to introduce a safety system for manufacturing facilities. Smart systems have recently become an important topic for use in the manufacturing industry, and these are now being developed with newly-introduced A.I.-based technologies. Smart manufacturing systems introduced with A.I. enable more efficient production than before, but these offer limited improvements at first. To further enhance production, collaborative intelligence can combine human creativity with the speed and accuracy of the equipment, complementing the shortcomings of each production method. However, collaboration in existing facilities requires new safety measures for workers because there is a higher propensity for accidents due to collisions. A recent study on worker-equipment collisions has shortcomings in that a collision between workers and equipment is inevitable because whether or not a collision occurs with a worker is checked only by using a sensor inside the robot. Therefore, this study installs a depth image camera outside the equipment, not a sensor inside, and the system can produce simulations in advance in a virtual environment before finalizing the design of the operation and equipment. A comparison of a simulation to the actual movement of a robot arm toward the point of collision with a worker confirmed an error of about 10.048 cm. Through this, it is possible to detect worker-equipment collision in advance.

摘要： The recent intelligent surveillance systems provide various services that have not existed before, such as proactive predictive surveillance, through the AI-based video analysis technology. However, there are common security and privacy challenges caused by malicious attacker and untrusted 3rd party in the CCTV cloud system. To solve this problem, we exploit the blockchain technology to insure integrity and security of cloud-based intelligent surveillance system. In this paper, we propose a new method for cloud-based CCTV blockchain system. Our contribution is to propose a new Merkle-Tree method for the efficient transmission of video data. The suggested method in this paper is efficient because it reduces the bandwidth required for transmission. It also has the advantage of enabling deduplication to reduce storage costs. Also, the proposed method can synchronize CCTV video data safely without exposing the privacy of the object in the course of synchronization.

摘要： Internet technology, as a product of the development of the network era, connects a large number of hardware devices, but the connection of many devices makes its corresponding security be greatly tested. The network security technology and the corresponding computer hardware security technology have become the focus of people's attention. At the same time, the construction of multimedia database based on this related technology has become the development trend of people's research and attention. Most of the conventional computer security technology focuses on the security construction of the operating system, which has certain openness, so its corresponding reliability is very low, but also uncontrollable. Based on this, this paper proposes a design scheme of the public security architecture on the embedded terminal, and realizes the design of the multimedia security broadcast control system based on this scheme, and realizes the play and storage of multimedia files, as well as the interaction between the corresponding media servers. The wireless network embedded security terminal designed in this paper includes client terminal identity authentication, corresponding media content protection and storage, and real-time broadcast content monitoring. Finally, the experiment is carried out based on the proposed design scheme. The experimental results show that the embedded security terminal proposed in this paper has obvious performance advantages, and its correctness and availability have been verified in practice.

摘要： With the emergence of cyber technology, the biggest evolution has been observed in the use of Internet for financial purposes, in particular for the Internet banking sector. However, with the increase in the number of Internet banking users, many security issues have been discovered. In the recent past, there have been many successful cyber-attacks on the Internet banking services (IBS) throughout the world. There exists a huge amount of various data about the security of the banking systems, however, proper analysis of such data using various learning techniques is needed for security assessment. In this research work, we aim to assess the security of IBS by developing a framework based on deep analysis of big data (available in various formats) and the existing security requirements of the country. We propose a framework consisting of 93 data categories to assess the security of the IBS. We evaluate our proposed approach on a case study consisting of the banks providing IBS in Pakistan. A total of 21 Pakistani banks providing Internet banking services are analyzed thoroughly using our proposed framework. The result uncovered many deficiencies in the Internet banking services of the analyzed banks. All these deficiencies are conveyed to the respective banks for verification and helping them to take corrective measures. In addition, a comprehensive set of security recommendations is developed for the banks, their customers and the regularity authority for improving Internet banking security.
