A Scalable Two-Phase Top-Down Specialization Approach for Data Anonymization using MapReduce on Cloud Abstract? A Scalable Two-Phase Top-Down Specialization Approach for Data Anonymization using MapReduce on Cloud. A large number of cloud services require users to share private data like electronic health records for data analysis or mining, bringing privacy concerns. Anonymizing data sets via…
A Secret-Sharing-Based Method for Authentication of Grayscale Document Images via the Use of the PNG Image With a Data Repair Capability Abstract? A new blind authentication method based on the secret sharing technique with a data repair capability for grayscale document images via the use of the Portable Network Graphics (PNG) image is proposed. An…
A Secure and Dynamic Multi-keyword Ranked Search Scheme over Encrypted Cloud Data Abstract? Due to the increasing popularity of cloud computing, more and more data owners are motivated to outsource their data to cloud servers for great convenience and reduced cost in data management. However, sensitive data should be encrypted before outsourcing for privacy requirements,…
A Secure and Privacy-Preserving Opportunistic Computing for healthcare Abstract? the pervasiveness of smart phones and the advance of wireless body sensor networks (BSNs), mobile Healthcare (m-Healthcare), which extends the operation of Healthcare provider into a pervasive environment for better health monitoring, has attracted considerable interest recently. However, the flourish of m-Healthcare still faces many challenges…
A Secure and Privacy-Preserving Opportunistic Computing Framework for Mobile-Healthcare Emergency. With the pervasiveness of smart phones and the advance of wireless body sensor networks (BSNs), mobile Healthcare (m-Healthcare), which extends the operation of Healthcare provider into a pervasive environment for better health monitoring, has attracted considerable interest recently. However, the flourish of m-Healthcare still faces…
A Secure Protocol for Spontaneous Wireless Ad Hoc Networks Creation Abstract? A Secure Protocol for Spontaneous Wireless Ad Hoc Networks Creation.a secure protocol for spontaneous wireless ad hoc networks which uses an hybrid symmetric/asymmetric scheme and the trust between users in order to exchange the initial data and to exchange the secret keys that will…
A secure remote user mutual authentication scheme using smart cards Abstract? Authentication thwarts unauthorised users from accessing resources in insecure network environments. Password authentication based on smart cards is one of the simplest and most ef?cient authentication methods and is commonly deployed to authenticate the legitimacy of remote users. Based on cryptographic techniques, several password…
A Secured Authentication System for MANETs using voice and Fingerprint Biometrics Abstract?Mobile Adhoc NETworks (MANET) are collections of wireless mobile devices with restricted broadcast range and resources and communication is achieved by relaying data along appropriate routes that are dynamically discovered and maintained through collaboration between the nodes. MANET is a self configuring, dynamic, multi…
A Security Modeling Approach forWeb-Service-based Business Processes. Several reports indicate that the highest business priorities include: business improvement, security, and IT management. The importance of security and risk management is gaining that even government statements in some cases have imposed the inclusion of security and risk management within business management. Risk assessment has become an…
A Segmentation and Graph-based Sequence Matching Method for Video Copy Detection Abstract? We propose in this paper a segmentation and graph-based video sequence matching method for video copy detection. Specifically, due to the good stability and discriminative ability of local features, we use SIFT descriptor for video content description. However, matching based on SIFT descriptor…
A Set of Complexity Measures Designed for Applying Meta-Learning to Instance Selection Abstract? A Set of Complexity Measures Designed for Applying Meta-Learning to Instance Selection. Some authors have approached the instance selection problem from a meta-learning perspective. In their work, they try to ?nd relationships between the performance of some methods from this ?eld and…
