A special aspect of multimedia database applications is that they require continuity in their data access. The maximum number of users who can simultaneously use the multimedia database is limited by this continuity requirement. Formulas for computing the maximum number of users and the associated memory requirement have been presented in the literature. However, these formulas do not take into...
We argue the necessity of universally veriiable secret sharing for secrets as individual users' cryptographic keys, and propose protocols to realize such secret sharing for two most common public-key cryptosystems: discrete logarithm based and integer factorization based. The universal veriiabil-ity achieves sharing secret with multi third parties as shareholders using two-party protocols in wh...
Empirical studies in the product development literature have shown that the users’ self-reported importance of product attributes differs from the derived importance of product attributes obtained through the attributes’ correlation with an external criterion such as user satisfaction. However, no study has examined this phenomenon in the context of software products. This investigation is impo...
Providing scalable on-demand interactive video service by means of multicasting and client buffering
True-VOD provides interactive on-demand (i.e., virtually zero start-up delay) video service by allocating each user a dedicated stream. Such streaming technique, however, cannot scale up to accommodate a large number of users. A more scalable solution is to use multicasting and client buffering. In this paper, we propose a client-initiated (client-pull) on-demand scheme in which short unicast s...
This paper presents politeness as a key social requirement for computer human interaction (CHI). Politeness is defined, in information terms, as offering the locus of control of a social interaction to another party. Software that creates pop-up windows is not illegal, but is impolite, as it preempts user choice. It is proposed that impolite software drives users away, while polite software att...
Upon release, Pokemon Go, an augmented reality technology based game garnered tremendous interest in the public, with an average of 20 million daily active users. The game combines geo-spatial elements along with gamification practices to incentivize it’s users movement in the physical world. Such incentives can have potential externalities to businesses associated with them. Using online revie...
The explosive wireless data service requirement accompanied with carbon dioxide emission and consumption of traditional energy has put pressure on both industry and academia. Wireless networks powered with the uneven and intermittent generated renewable energy have been widely researched and lead to a new research paradigm called green communication. In this paper, we comprehensively consider t...
Optimised virtual keyboards are potentially efficient and fast for expert users, but they are difficult and slow for novice users due to the visual search requirement. Introducing structure and order to the layout may ease the visual searching process. By means of a Metropolis algorithm with an added alphabetical bias term to the Fitts-digraph energy function previously used (Zhai, Hunter, & Sm...
Requirements engineering is a critical task in the construction of correct computer systems. It is not however a certain task, and it causes serious problems in computer systems. This is due to the existence of a gap between users and the development process introduced by a manual interpretation of their needs. In order to ascertain an accurate translation from users requirements to speciica-ti...
Predicting personality is essential for social applications supporting human-centered activities, yet prior modeling methods with users’ written text require too much input data to be realistically used in the context of social media. In this work, we aim to drastically reduce the data requirement for personality modeling and develop a model that is applicable to most users on Twitter. Our mode...
