Recently,with the spread of online services involving websites,attack-ers have the opportunity to expose these services to malicious actions.To protect these services,A Completely Automated Public Turing Test to Tell Computers and Humans Apart(CAPTCHA)is a proposed technique.Since many Arabic countries have developed their online services in Arabic,Arabic text-based CAPTCHA has been introduced to improve the Usability for their users.More-over,there exist a visual cryptography(VC)technique which can be exploited in order to enhance the security of text-based CAPTCHA by encrypting a CAPTCHA image into two shares and decrypting it by asking the user to stack them on each other.However,as yet,the implementation of this technique with regard to Arabic text-based CAPTCHA has not been carried out.Therefore,this paper aims to implement an Arabic printed and handwritten text-based CAPTCHA scheme based on the VC technique.To evaluate this scheme,experi-mental studies are conducted,and the results show that the implemented scheme offers a reasonable security and Usability levels with text-based CAPTCHA itself.

The public has access to a range of mobile applications(apps)for disasters.However,there has been limited academic research conducted on disaster apps and how the public perceives their Usability.This study explores end-users'perceptions of the Usability of disaster apps.It proposes a conceptual framework based on insights gathered from thematically analyzing online reviews.The study identifies new Usability concerns particular to disaster apps'use:(1)content relevance depends on the app's purpose and the proximate significance of the information to the hazard event's time and location;(2)app dependability affects users'perceptions of Usability due to the lifesafety association of disaster apps;(3)users perceive advertisements to contribute to their cognitive load;(4)users expect apps to work efficiently without unnecessary consumption of critical phone resources;(5)appropriate audio interface can improve Usability,as sounds can boost an app's alerting aspect;and,finally(6)in-app browsing may potentially enhance users'impression of the structure of a disaster app.As a result,this study argues for focussed research and development on public-facing disaster apps.Future research should consider the conceptual framework and concerns presented in this study when building design guidelines and theories for disaster apps.

Most of the security strategies today are primarily designed to provide security protection,rather than to solve one of the basic security issues related to adequate software product architecture.Several models,frameworks and methodologies have been introduced by the researchers for a secure and sustainable software development life cycle.Therefore it is important to assess the Usability of the popular security requirements engineering(SRE)approaches.A significant factor in the management and handling of successful security requirements is the assessment of security requirements engineering method performance.This assessment will allow changes to the engineering process of security requirements.The consistency of security requirements depends heavily on the Usability of security requirements engineering.Several SRE approaches are available for use and each approach takes into account several factors of Usability but does not cover every element of Usability.There seems to be no realistic implementation of such models because the concept of Usability is not specific.This paper aims at specifying the different taxonomy of Usability and design hierarchical Usability model.The taxonomy takes into account the common quality assessment parameters that combine variables,attributes,and characteristics identified in different approaches used for security requirements engineering.The multiple-criteria decision-making(MCDM)model used in this paper for Usability evaluation is called the fuzzy AHP-TOPSIS model which can conveniently be incorporated into the current approach of software engineering.Five significant Usability criteria are identified and used to evaluate the six different alternatives.Such strategies are graded as per their expected values of Usability.

In order to assess the Usability of steering wheel control interfaces in motorsport,it is necessary to employ a set of appropriate methods.The method selection process first involves identifying the relevant motorsport-based Usability criteria.The unique factors associated with context of use in motorsport are then defined.These are employed to synthesize a set of key performance indicators(KPIs)that require specific analysis.The first KPI relates to error rates;these should be minimized,particularly under high cognitive load on the primary.The second KPI involves task times;these should be minimized not just to reduce distraction,but also to improve competitive performance.The third KPI states that Usability should be optimized to minimize visual distraction.The fourth KPI advocates the minimizing of interface task load to reduce the effect on the primary task.The final KPI states that interface functionality should be easy to learn and recall.The KPIs provide clear goals to guide the identification of the most appropriate methods for each aspect of Usability.Methods categories are devised and sets of appropriate methods selected based on the KPIs.These then combine into a toolset with an associated application process with the overall goal of providing a means by which motorsport interfaces may be both analysed and improved.

Transformation from conventional business management systems tosmart digital systems is a recurrent trend in the current era. This has led to digitalrevolution, and in this context, the hardwired technologies in the software industry play a significant role However, from the beginning, software security remainsa serious issue for all levels of stakeholders. Software vulnerabilities lead to intrusions that cause data breaches and result in disclosure of sensitive data, compromising the organizations’ reputation that translates into, financial losses andcompromising software Usability as well. Most of the data breaches are financiallymotivated, especially in the healthcare sector. The cyber invaders continuouslypenetrate the E- Health data because of the high cost of the data on the darkweb. Therefore, security assessment of healthcare web-based applicationsdemands immediate intervention mechanisms to weed out the threats of cyberattacks for the sake of software Usability. The proposed disclosure is a unique process of three phases that are combined by researchers in order to produce andmanage Usability management framework for healthcare information system. Inthis most threatened time of digital era where, Healthcare data industry has bornethe brunt of the highest number of data breach episodes in the last few years. Thekey reason for this is attributed to the sensitivity of healthcare data and the highcosts entailed in trading the data over the dark web. Hence, Usability managementof healthcare information systems is the need of hour as to identify the vulnerabilities and provide preventive measures as a shield against the breaches. The proposed unique developed model of Usability management workflow is preparedby associating steps like learn;analyze and manage. All these steps gives an allin one package for the healthcare information management industry because thereis no systematic model available which associate identification to implementationsteps with different evaluation steps.
