Identity-related processes have been identified as important in explaining virtual community (VC) member behavior as well as informing system design of VCs. In particular, the two distinct identity processes of self-verification and identification have been identified and investigated separately, portrayed as two distinctive or contradictory identity processes with different practical implicati...

We define identity theft as the unauthorized use and exploitation of another individual’s identity-corroborating information. Published research proposing technical countermeasures is sparse, in contrast to a number of recent proposals to address the sub-problem of phishing. We first identify some underlying problems facilitating identity theft. To address identity theft and the use of stolen o...

Identity-Based Cryptosystem plays an important role in the modern cryptography world, due to the elimination of the costly certificate. However, all practical identity-based encryption schemes require pairing operation in the decryption stage. Pairing is a heavy mathematical algorithm, especially for resource-constrained devices such as smart cards or wireless sensors. In other words, decryptio...

Expert practical knowledge emerges through sustained participation in some community of practice. However, participation alone is not the sole factor that contributes to high levels of expertise in the workplace. Our multi-year ethnographic study of one fish hatchery and associated activity systems shows that deeper experiential (practical) and conceptual (scientific) knowledge emerged when fis...

This paper discusses the economics of electronic identity (eIdentity) from both theoretical and practical perspectives. Personal identity data are becoming increasingly important in online transactions, and they have never been monetised to the extent they are today. Consequently, there is a need for an improved understanding of the economic externalities resulting from the electronic use of id...

The object-oriented paradigm is one of the central programming paradigms of our time. The following description is a generally accepted characterization of that paradigm: “An object has state, behavior, and identity” [9]. The concept of object identity plays an important role here insofar it is the only characteristic element that is not available in purely declarative programming languages wit...

It has always been a critical issue to find efficient methods for fast revocation of a user’s identity in identity (ID)based cryptosystems. Unfortunately, none of the previous ID-based cryptography can find a practical way. Libert et al. and Baek et al. respectively propose an ID-based mediated encryption scheme based on the practical ID-based encryption scheme from bilinear pairing due to Bone...
