Self-Enforcing Access Control for Encrypted RDF
The amount of raw data exchanged via web protocols is
steadily increasing. Although the Linked Data infrastructure could
potentially be used to selectively share RDF data with different individuals
or organisations, the primary focus remains on the unrestricted
sharing of public data. In order to extend the Linked Data paradigm to
cater for closed data, there is a need to augment the existing infrastructure
with robust security mechanisms. At the most basic level both access
control and encryption mechanisms are required. In this paper, we propose
a flexible and dynamic mechanism for securely storing and efficiently
querying RDF datasets. By employing an encryption strategy based on
Functional Encryption (FE) in which controlled data access does not
require a trusted mediator, but is instead enforced by the cryptographic
approach itself, we allow for fine-grained access control over encrypted
RDF data while at the same time reducing the administrative overhead
associated with access control management
PATExpert: Semantic Processing of Patent Documentation
PATExpert is a recently started “Specific Targeted
Research Project” funded by the EC in FP 6, IST priority.
PATExpert’s goal is to change the paradigm currently followed
for patent processing from textual to semantic. We are about to
develop a semantic multimedia content representation based on
Semantic Web technologies for selected technology areas and to
investigate some central topics from the semantic representation
angle: patent retrieval and classification, content extraction, generation
of multilingual user comprehensible patent information,
visualization of and navigation in patent content spaces, and
patent valuing and technology area assessment
