Digital image security plays an essential role in the shared communication model. Encryption and decryption process is commonly applied to securely transmit the images in various real-time applications. In addition, the generation of encryption/decryption keys is also essential to achieve enhanced image security. This study presents a multiple share creation scheme with an optimal signcryption (MSS-OSC) technique for digital image security. The MSS-OSC technique primarily generates a set of various shares for every digital image that needs to be transmitted. In addition, the encryption of generated shares takes place via the optimal signcryption (OSC) technique. Moreover, genetic programming (GP) is employed to optimally choose the keys involved in the encryption and decryption process. The detailed experimental validation of the MSS-OSC technique is investigated using a set of benchmark test images. The results analysis demonstrated that the MSS-OSC technique had a superior performance by accomplishing maximum digital image security.
The stagnation of the domestic market has brought the majority of the small and medium-sized enterprises (SME) to their knees, leading them to reinvent their way of doing business and find new strategies in order to survive and grow when the environmental conditions are deeply changing. On the one hand, new trends create a strong disruption on a structural level among the productive fabrics, but on the other hand, they represent also an opportunity, which opens new scenarios and new possibilities for the relaunch of SMEs. Among the most important challenges for Italian SMEs is internationalization, which is the possibility for enterprises to trade their goods not only on the domestic market but also on the foreign markets trying to find new opportunities to obtain some advantages. This is a very complicated process, traumatic and challenging in term of resources, but the possibility to have a genetic patrimony and a productive value, as the ones of the “Made in Italy, gives to the products of Italian enterprises a high level of competition and strong differentiation, making this process more accessible. The growth and competitiveness of enterprises, in particular SMEs, increasingly depend on the ability to apply new knowledge, working methods, and technologies as well as on the opportunity to participate in the commercialization of research developments in order to create new products, services or processes. Therefore, companies should strive to benefit from the opportunities and competitive advantages that innovation brings. SMEs play an important role in economic growth and provide most of the new jobs in Italy. Within the framework of this paper, the insight into the SMEs internationalization process is presented. The article provides an analysis of SMEs in the process of internationalization. Besides it concentrates on the new threats and opportunities represented by the new industrial revolution - Industry 4.0. Analyzing the impact of Industry 4.0 on the internationalization of Italian SMEs, the authors explain the solutions that are being used and the ones that should be taken.
The relevance of the study is that globalization and the integration of the international economy provide excellent opportunities for economic development through international trade and investment. It is necessary to make the product and services more competitive. One of the factors determining the competitiveness of trade is how quickly and how economically the goods can be delivered. The competition in the logistics industry is continually growing, which forces participants to improve their efficiency, improve quality and reduce costs. In these conditions effective IT solutions are vital tools for logistics and the ability to manage the logistics processes in the business environment in the context of globalization is a factor of competitiveness. Within the framework of this paper, the existing business processes of cargo delivery were described. The study of the process of interaction of international supply chain participants made it possible to identify the ineffectiveness of existing processes to understand what can be replaced and corrected with the introduction of blockchain technology. The main reason of inefficiency is the low level of business processes digitalization. The cases of existing blockchain projects for the logistics industry were investigated. The article provides possible cases of using blockchain for the logistics industry.
