Signing contracts on the telephone

27.01.2010
Researchers at Fraunhofer SIT have developed a digital signature for Internet telephony that allows the legally binding archiving of calls. At the GSMA Mobile World Congress in Barcelona (Hall 2, Stand E41) the experts will be demonstrating how the VoIPS software works.

Internet telephony has developed from a niche product into standard technology in recent years. Most telephone providers switched their background technology to Voice over IP, or VoIP for short, long ago. BITKOM, the German association for information technology, cites the economical rates and additional functions such as interaction between e-mail and voicemail as the primary forces driving this change.

The fusion of telephone and Internet is also resulting in new business forms and services that must be secure against tapping and manipulation. For example, the possibility of concluding or changing contracts by telephone. With this in mind, the security experts at the Fraunhofer Institute for Secure Information Technology SIT in Darmstadt have developed software that provides legally-binding archiving of VoIP telephone calls.

Let’s look at a possible application: A banker talks to a customer. This talk leads to a contract that is to be recorded in order to provide evidence. The banker presses the record button on his or her telephone, and the customer is automatically asked for consent. If the customer confirms, recording begins in accordance with the VoIPS principle, which is based on digital signature technology. The software from SIT divides the telephone calls into intervals and signs the transmitted data packets with corresponding metadata. To keep the separate packages from being stored in the wrong order, each interval is given a distinctive encoded "stamp". In this way, VoIPS combines all the important information on a stored call into an indivisible chain. Any changes to the calls will be noticed, no matter when the change is made.

VoIPS is suitable for all situations where companies, public authorities, banks or insurance companies want to store calls with a tamper-proof method in order to rule out later legal uncertainties. For example, VoIPS could be used for telephone banking or for recording conversations in hospital operating rooms. Based on the applicable standards for Internet telephony, VoIPS can be installed on any IP telephone system.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
