Software requirement analysis is an essential step in software development process, which defines what is to be built in a project. Requirements are mostly written in text and will later evolve to fine-grained and actionable artifacts with details about system configurations, technology stacks, etc. Tracing the evolution of requirements enables sta...

In this paper, we proposed an image authentication method based on least significant bit (LSB) hiding and double random phase encoding (DRPE) technique. An image that needs to be authenticated is first encrypted using DRPE algorithm. All amplitude information in this encrypted image is discarded and the phase mask is reserved. Then, the phase image...

Orthogonal defect classification (ODC), the most influential framework for software defect classification and analysis, provides valuable in-process feedback to system development and maintenance. Conducting ODC classification on existing organizational defect reports is human-intensive and requires experts’ knowledge of both ODC and system domains...

We present a new method to identify navigation related Web usability problems based on comparing actual and anticipated usage patterns. The actual usage patterns can be extracted from Web server logs routinely recorded for operational websites by first processing the log data to identify users, user sessions, and user task-oriented transactions, an...

In recent years, more organizations began to ad-dress usability problems to improve their competitive position and foster customer loyalty. Although there are some clas-sification schemes to address usability problems, there is no cause-effect framework to enable in-process usability feedback and improvement. Orthogonal defect classification (ODC)...
