Trajectory privacy-preserving for Location-based Social Networks (LBSNs) has been received much attention to protect the sensitive location information of subscribers from leaking. Existing trajectory privacy-preserving schemes in literature are confronted with three problems: 1) it is limited for privacy-preserving by only considering the location anonymization in practical environment, and the sensitive...
The inevitability of IPv6 has come to fore. How to resolve the problem of IP address registration has been a great challenge for network management. The existing solution uses manual registration mechanism, not suitable for dealing with massive IPv6 addresses. Based on the Extensible Provisioning Protocol, we propose an “EPP-IP” mechanism to achieve a flexible and automatic registration management...
Deterministic encryption for low entropy personally identifiable information(PII) is vulnerable to dictionary attack. It is particularly so because of an expedient method to enumerate possible PII'splain text instead of all possible keys. Deterministic encryption, however, is indispensable in the generation of hash or index of PII. This paper presents a novel mechanism to frustrate dictionary attacks...
Formative assessment is an important method to control the quality of the learning process. In this paper, a framework for the formative assessment management system is presented. This three-layer system framework is based on the J2EE technologies. The principles of data structure design were discussed. We discuss formative assessment based on fuzzy evaluation in details which included establish the...
In this paper, a framework for the information management system of Mandarin test (IMSMT) is presented. The IMSMT consist of functional models that are registration, draw straws, test online, upload speech file, grade online, results release, record, examiner management. This three-layer system framework is based on the J2EE technologies. The principles of data structure design were discussed. The...
