Recent and recurrent leaks of highly confidential information, prompted Professor Luc Moreau and Rocio Aldeco-Perez at the University's School of Electronics and Computer Science to take a concept which is more commonly used in the art world and derive a tool that operates on private data.
In a paper entitled Provenance-based Auditing of Private Data Use just published in the BCS International Academic Research Conference - Visions of Computer Science, the academics describe how a tool called Provenance can be applied to personal and confidential information so that an audit trail can be analysed to see where the information has come from, how it is being used and how it can be made secure.
As part of their research, the academics developed a case study based on private data in a university and the requirements of the Data Protection Act.
'Provenance is a term which comes from diverse areas such as art, archaeology and palaeontology and describes the history of an object since its creation,' said Professor Moreau. 'Its main focus is to establish that the object has not been forged or altered, we have found that we can now do the same audit with private data.'
According to Professor Moreau, who extended the concept of Provenance to service-oriented architectures when he embarked on the EU Provenance Project in 2005, the auditing capabilities of this tool will make it possible to redesign systems so that they incorporate secure auditing strategies and therefore are more robust and trusted.
'At the moment when data is leaked, there is no systematic way to analyse the scenario,' said Professor Moreau. 'We are now working towards the first prototype capable of auditing this data.'

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
