A new system preserves the right to privacy in Internet searches

09.11.2009
A team of Catalan researchers has developed a protocol to distort the user profile generated by Internet search engines, in such a way that they cannot save the searches undertaken by Internet users and thus preserve their privacy. The study has been published in the Computer Communications magazine.

Just imagine someone from Company X who uses the Google search engine to obtain information about a certain technology. If Company Y, a competitor of X, should discover this situation, it could infer that the abovementioned technology is going to be used in X's new products, and with that information it could obtain a competitive edge.

In the same way, a mass media enterprise that finds out the searches undertaken by the competition's journalists could infer what news items they are working on and beat them to it. A personal report could also be drawn up on someone based on their searches.

In order to solve these types of situations, a team of researchers from three Catalan universities (the Rovira i Virgili University, the Autónoma of Barcelona and the Oberta of Catalonia) has developed a system which preserves user privacy via a new computer protocol, whose details are published in the Computer Communications magazine.

"It is a model based on cryptographic tools which distort the profile of users when they use search engines on Internet", explains Alexandre Viejo to SINC. He is one of the authors of the study and a researcher at the Computer Engineering Department of the Rovira i Virgili University, "in such a way that their privacy is preserved".

Search engines such as Google, Yahoo and Microsoft Live search save the profiles of their users (via an analysis of the searches they undertake) with the argument that they are more familiar with their interests and offer a more efficient response.

There currently exist types of software which provide anonymous navigation, such as the Tor network, but the new system "offers a clear improvement in response time". Nevertheless, Alexandre Viejo acknowledges that the application of the protocol delays searches slightly, "but it can be perfectly assumed by the user".

The tool prototype has already been tried in closed (research centre intranets) and open (internet) environments, "and the results allow us to be optimistic with the global implementation of the model". The researchers are now working on the development of a final user version and trust that it will soon be easily integrated into the main platforms and browsers.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
