There are many applications, such as detecting a human’s head pose (position and rotation), tracking whether drivers are paying attention or not, applying augmented reality, etc. This paper proposes to evaluate and decide what are the optimal techniques of image enhancement that can be used to improve different algorithms of FLD. After proposing different pipelines of contrast enhancement and grayscale conversion to enhance the image before applying the FLD algorithm, the results show that the performance will not increase drastically if an image enhancement pipeline is used, but for the reason that this step will not consume a lot of time in the process of detection, it is a step worth considering.","PeriodicalId":302692,"journal":{"name":"2022 21st RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"24 588 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116830960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aside from generating significant speedups of everyday procedures, OCR has a considerable role in the preservation of historical sources of information. Most of the World War 2 (WW2) documents are of great importance, especially with applications in virtual archives, museums, and research. The situation asks for an efficient, yet not aggressive, transcribing method using OCR tools. This paper describes an approach in the context of the given problem. The focus is oriented towards extracting the information from documents affected by their age, but with simpler structures, mainly split into paragraphs, such as letters and military reports. The approach is based on combining the results of multiple OCR engines, with the final objective of achieving better performance compared to the individual performance of each engine.","PeriodicalId":302692,"journal":{"name":"2022 21st RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130168507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantum communications are based on quantum key distribution, which uses quantum mechanical processes to generate cryptographic keys and to securely distribute them to the users in the networks. There already are quantum key distribution devices on the market, but it is ill advised to fully rely on such devices, in the national security use cases. Thus, each country in EU is actively trying or has already succeeded in developing their own prototypes. We present our roadmap for building such a quantum key distribution prototype and the current status of the R&D activities undertaken by our collaboration ITIM-UTCN.","PeriodicalId":302692,"journal":{"name":"2022 21st RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131008155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout the years, various protective measures have been developed to prevent against an increasing number of exploits that are becoming more and more complex and refined. Instead of concentrating on general mitigating techniques, our proposal orients towards creating performant honeypots which are safe and isolated environments that attract malicious users for the purpose of studying their invasive techniques. Firstly, this paper introduces an original method of describing, from a mathematically point of view, recursively defined topologies and presents a proposed algorithm used in constructing them. Secondly, we suggest a novel architecture which combines recursively defined topologies (RDT), software-defined networks (SDN) and an orchestrator engine for containerized infrastructure in order to develop a high-interaction honeypot which simulates an entire data center using a single physical host. The proposed implementation may represent a promising framework used as a developing platform for more complex honeypots used in either researching malicious human behavior or in the IT industry as a defensive measure. Regarding achieved results, the proposed implementation accomplishes notable results in deceptive techniques, isolation and effortless configurability.","PeriodicalId":302692,"journal":{"name":"2022 21st RoEduNet Conference: Networking in Education and Research (RoEduNet)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122873328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
