This paper addresses the quality attributes of the strategy and tactics of the software project plan that should be in place in order to deliver a good software product. It presents an initial work in which a set of required quality attributes is identified to evaluate the quality of the strategy and tactics of the software project plan, based on the Business Motivation Model (BMM) and the quality attributes available in the ISO 9126 standard on software product quality.展开更多

The codes may originate from different entropy attributes and schemes, such as true random and digital random number generators. Businesses, organizations, and academic institutions have adopted OTP methods for credit card transaction confirmation, recalling forgotten passwords, and validating web portal accounts. This paper proposed a new method in authenticating login credentials using a 3 × 3 matrix and random system key as Two-Factor Authentication (2FA) with an SMS-enabled feature. We used the 6-codes pseudorandom method and a 4-codes validation to allow mobile flexibility and ensure that the user has the required access. The page link and evaluation form are sent to students, IT professionals, and researchers. The results showed respondents are satisfied in terms of functionality, usability, efficiency, and reliability. The developed system could safeguard information, disallow unauthorized access, and impose acceptable data protection measures and minimal system requirements to use the system.展开更多
