Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...

In this paper, we present a multilingual database specifically designed to develop technologies for rich audio-visual scene description in meeting-room environments. Part of that database includes the already existing CHIL audio-visual recordings, whose annotations have been extended. A relevant objective in the new recorded sessions was to include situations in which the semantic content can n...

This paper describes our design policy and prototype data collection of RWC (Real World Computing Program) multimodal database. The database is intended for research and development on the integration of spoken language and visual information for human computer interactions. The interactions are supposed to use image recognition, image synthesis, speech recognition, and speech synthesis. Visual...

A system is proposed that combines textual and visual statistics in a single index vector for content-based search of a WWW image database. Textual statistics are captured in vector form using latent semantic indexing (LSI) based on text in the containing HTML document. Visual statistics are captured in vector form using color and orientation histograms. By using an integrated approach, it beco...

We demonstrate iMONDRIAN, a component of the MONDRIAN annotation management system. Distinguishing features of MONDRIAN are (i) the ability to annotate sets of values (ii) the annotation-aware query algebra. On top of that, iMONDRIAN offers an intuitive visual interface to annotate and query scientific databases. In this demonstration, we consider Gene Ontology (GO), a publicly available biolog...

An organizational information system (OIS) has been designed and implemented using visual web Java Server Faces (JSF) on NetBeans Integrated Development Environment (IDE) 6.5 in Instrumentation and Informatics Research Laboratory, Department of Electronics Science, Gauhati University, INDIA. The database for the system is developed using My Structured Query Language Version 5.0 (MySQL). The con...

In this paper we examine how Self-Organizing Maps (SOMs) can be used in detecting and describing emergent ontological relations between semantic objects and object classes in a visual database. The ontological relations we have studied include co-existence, taxonomies of visual and semantic similarity and spatial relationships. The used database contains 2618 images, each of which belongs to on...

Since most multimedia database systems are built on top of object or object-relational database systems, they inherit the underlying query facilities. The approach we present in this paper is in two steps. The rst step is to design a multimedia query language that will be used as an internal language. The second step is to deene an equivalent visual query language and a translator to translate ...

In cyberspace security of private data is a prominent issue. Beside the reliable algorithm for automatic authentication, providing the security of the server database is considerable. In this paper a technique to secure the database of an iris-based biometric system is proposed. We employed visual cryptography, permutation and a block-based saving procedure to protect the template from maliciou...

A synchronous database of acoustic and 3D facial marker data was built for audio-visual laughter synthesis. Since the aim is to use this database for HMM-based modeling and synthesis, the amount of collected data from one given subject had to be maximized. The corpus contains 251 utterances of laughter from one male participant. Laughter was elicited with the help of humorous videos. The result...
