Abstract:
The main aim of the Linked Open Data (LOD) project is to publish data publicly without access restriction in order to be consumed upon Unified Resource Identifier (URI) resolution. The latter provides more description about the resources being represented through the resolvability and discoverability of more others resources. Sometimes, data/resources need to undergo an access restriction to be consumed only on a small scale for keeping its confidentiality. However, while the power of the LOD resides in the resolvability of more URIs related to the resources in hand, a curious question imposes itself: how can we achieve a compromise between URI resolvability and access restriction? This paper discusses how the represented data cam be secured. It illustrates how the Public Key Infrastructure (PKI) can be applied to restrict the access to confidential resources of represented data being published using the Linked Data Principles (LDP), while maintaining the resolvability of such restricted resources. This brings out a new era of research related to the counter part of LOD, a research topic called the Linked Closed Data (LCD). A good example to elaborate this compromise question is a case study retrieved from the Cyber Forensics (CF) field where the tangible Chain of Custody (CoC) is represented using the LDP to exploit the resolvability feature of such principles on different resources of the Electronic-CoC (e-CoC). The latter should also obey an access restriction in order to be shared only between role players who published the data and juries who are going to consume it.
