The Stinson-Wei traceability scheme (known as traceability scheme) was proposed for broadcast encryption as a generalization of the Chor-Fiat-Naor traceability scheme (known as traceability code). Cover-free family was introduced by Kautz and Singleton in the context of binary superimposed code. In this paper, we find a new relationship between a traceability scheme and a cover-free family, whi...

The literature lists many benefits of requirements traceability and standards suggest that it should be practiced. However, available literature concentrates on industries developing complex and large systems with several thousands of requirements. Thus, the companies developing systems with only approximately a hundred requirements face the challenge to define what traceability information to ...

Requirements traceability is central to the issue of requirements management, which is essential for producing quality software. Our focus on requirements traceability addresses aspects related to software development and evolution. Our survey deals both with technical and managerial aspects and aims at contextualizing requirements traceability as well as providing basic reference on the subjec...

Requirements traceability offers many benefits to software projects, and it has been identified as critical for successful development. However, numerous challenges face the implementation of traceability in the software engineering industry. Some of these challenges can be overcome through organizational policy and procedure changes, but the lack of cost-effective traceability models and tools...

This study aim is to provide a feasible and effective way for the government supervision, agricultural enterprises and consumers to obtain traceability information. This study researches traceability of agricultural products. Through the analysis of the participators, the influence of the agricultural products circulation pattern of supply chain, traceability security system and tracing process...

Software traceability is the ability to relate artefacts created during the development life cycle of software system. Traceability is essential in the software development process and it has been used to support several activities such as impact analysis, software maintenance and evolution, component reuse, verification and validation. Moreover, the importance of traceability in the software d...

Traceability exists in many food supply chains for valid economic reasons, one of which is improving food safety and quality. Some politicians and consumer groups are calling for increased identity preservation in systems where traceability has not yet been adopted. In this paper, we explore the implications of adding traceability to a food supply chain that already includes an inspection proto...

Software traceability is a required component of many software development processes. Advocates of requirements traceability cite advantages like easier program comprehension and support for software maintenance (i.e., software change). However, despite its growing popularity, there exists no published evaluation about the usefulness of requirements traceability. It is important, if not crucial...

Traceability, the ability to track parts and products, is a necessity for many enterprise applications. These include pilferage reduction, counterfeit prevention, and targeted recalls. In this paper, we share lessons learned from a comparative analysis of two state of the art traceability data management systems: a federated system for parts traceability; and a distributed system for distributi...

The Food & Drug Administration has begun requiring that electronic submissions of regulated clinical studies utilize the Clinical Data Information Standards Consortium data standards. Within regulated clinical research, traceability is a requirement and indicates that the analysis results can be traced back to the original source data. Current solutions for clinical research data traceability a...
