Automated batch Certificate generation and verification system
2017Co-Authors: Ahmed Dalhatu Yusuf, Moussa Mahamat Boukar, Shahriar ShamiluuluAbstract:Nowadays several numbers of Certificate generation and verification systems have been developed to take the bite out of difficulties faced in the manual system and minimize the processing time for generating a Certificate. These systems are functioning based on the predefined Template and predefined Template format by the system developer. However, some systems allow end-user to define Template and Template format by the use of XML. The technology mentioned above requires an end-user to have minor knowledge of XML to be able to define Template and Template format. This research work enables an end-user to define Certificate Template and Template format without the requisite of XML knowledge by clicking few buttons and typing from the system GUI, verifying the Certificate and generating one or more Certificate(s) simultaneously in an instantaneous manner.

Euro-Par Workshops - Academic Achievement Recognition and Verification Using Blockchain
Euro-Par 2019: Parallel Processing Workshops, 2020Co-Authors: Axel Curmi, Frankie InguanezAbstract:Falsification of Certificates is a growing concern and the verification process can be a lengthy and challenging one. In this research, we are proposing a distributed ledger-based solution for the storage and verification of academic qualifications. An entity that would want to verify Certificates can make use of our API service that would, in turn, scan a Certificate, find the matching Certificate Template, extract the necessary data and verify it from a blockchain stored copy. In this research, we also propose an improved manner of verifying the ownership of a blockchain public address which also does not allow a user to present an address of a third party, this being one of the common security concerns of similar solutions. We also calculate the possible costs to adopt this system in all EU countries taking into consideration different gas prices, which is a determining factor to the transaction cost of a blockchain network. We conclude that a blockchain based Certificate verification system addresses various issues related to document forgery and is a viable solution even with the current state of technology.

Ethereum-Blockchain-Based Technology of Decentralized Smart Contract Certificate System
IEEE Internet of Things Magazine, 2020Co-Authors: Rui Xie, Yuhui Wang, Tan Mingzhou, Wei Zhu, Yang Zhongjie, Gwanggil JeonAbstract:Traditional paper Certificates and electronic Certificates have difficulties in preservation and management, not to mention other problems concerning inconvenient verification, poor reliability, anti-counterfeiting and anti-tampering. This paper proposes a scheme designed to build a decentralized Certificate system that is based on blockchain technology and smart contract, in which a set of blockchain Certificate system aiming at providing blockchain Certificate services for college students' innovation and entrepreneurship competition is developed. In this system, certain functions of the Certificate about management, issuing, verification and revocation are realized via smart contract. Signer information, Certificate Template and Certificate information are stored in a smart contract that adopts structured data, thereby realizing more convenient callings in querying and validating Certificate.

Strategies in printed advertisements focused on the Viennese Condominium Market
2014Co-Authors: Martina Hoffmann, Giovanna Ferluga, Filippo Gagliano, M. Rosa Trovato, A. ValentiAbstract:Since December 1st, 2012 the new Energy Performance Certificate Template-law 2012 is valid. This law was implemented to encourage customers to buy more energy efficient objects. As this new legal situation has great influence on daily business of real estate agents, it is seen to be important to observe the changes on the real estate market very carefully. This study focused on the Viennese Condominium Market. In a previous study more than 5000 Viennese condominium advertisements, listed in the IMMO Kurier were analyzed and worked out. In fact more than 75% of the listed advertisements in the IMMO Kurier included the requested heating parameter (Hoffmann, ERES 2013). But how does this new information influence the transparency of the real estate market?In which way does the Viennese Condominium Market become more transparent for customers?What are the benefits and what are the disadvantages?It was decided to repeat the investigations by comparing the results from November 17th, 2012 and December 22nd, 2012 with the results from November 16th, 2013 and December 21st, 2013.Several strategies of advertising condominiums on the Viennese real estate market can be identified:For offered Condominiums:The advertisement includes the district/address, information on prices, square meters and heating parameter.Summing up, the transparency of the real estate market is not guaranteed by forcing real estate agents to show the heating parameters in their advertisements, especially, if further information on price and square meters has not to be added.

Redesign of Real Estate Market by Legal Regulation
2013Co-Authors: Martina HoffmannAbstract:This paper shows how the real estate market is influenced by the new Energy Performance Certificate Template-law 2012, focused on condominium market in Vienna. The purpose of the following study was to analyze the changed role of real estate agents and to show their reactions towards the new market situation. Therefore it was decided to observe the advertisement market carefully. The observation concentrated on the following two questions: 1. Changed role of the real estate agent 2. Changes on the condominium advertisement market until December, 1st, 2012?Since November 17th, 2012 until December 22nd 2012, 1474 advertisements of the Viennese condominium market, listed in the IMMO Kurier were analyzed. The IMMO Kurier is a supplement of a well-known Austrian daily newspaper, which appears every Saturday. Due to the investigations it could be identified, that the total amount of advertisements decreased whereas the quantity of advertisements including the calculated heating demand increased. Therefore real estate agents are fulfilling the legal requirements of EAVG 2012 and do not risk penal provisions. In conclusion the real estate market was redesigned by EAVG 2012 and the impacts have to be observed and analyzed.
