This paper presents a method for a decentralised peer-to-peer software license validation system using cryptocurrency blockchain technology to ameliorate software piracy, and to provide a mechanism for software developers to protect copyrighted works. Protecting software copyright has been an issue since the late 1970’s and software license validation has been a primary method employed in an at...

Software security encompasses the measures taken to ensure confidentiality, integrity and availability in software systems. In present-day software development, security is often an afterthought rather than part of the software development life-cycle. In order to reveal potential security flaws before a software system is actually implemented, security aspects should be taken into account start...

The software testing process example, as illustrated in Figure 19, is an 11-step testing process that follows the “V” concept of testing. The “V” represents both the software development process and the 11-step software testing process. The first five steps use verification as the primary means to evaluate the correctness of the interim development deliverables. Validation is used to test the s...

Modeling of modern production plants often requires that the system provides means to cope with frequent changes in topology and equipment and can easily be adapted to new or changing requirements. For validation in form of simulation, however, usually a complete specification of both, the production control software and the physical elements of the manufacturing plant is required. We therefore...

The development of highly reliable software is key to the success of many of today's medical devices and instruments. The development of such software is achieved through a phased development process that starts with requirements and ends when the product reaches the market Quality medical sofiware is achieved by applying verification and validation techniques throughout the different developme...

Software security encompasses all the measures taken to ensure confidentiality, integrity and availability in software systems. In present-day software development, security is often just an afterthought rather than part of the software development life-cycle. In order to reveal potential security flaws before a software system is actually implemented, security aspects should be taken into acco...
