Improving the boneh-franklin traitor tracing scheme

Arjen Lenstra, Pascal Junod, Alexandre Karlov

Traitor tracing schemes are cryptographically secure broadcast methods that allow identification of conspirators: if a pirate key is generated by k traitors out of a static set of l legitimate users, then all traitors can be identified given the pirate key ...

Tracking Odor Plumes in a Laminar Wind Field with Bio-Inspired Algorithms

Alcherio Martinoli, Thomas Lochmatter

We introduce a novel bio-inspired odor source localization algorithm (surge- cast) for environments with a main wind ﬂow and compare it to two well-known algorithms. With all three algorithms, systematic experiments with real robots are carried out in a wi ...

Saliency Detection for Content-aware Image Resizing

Sabine Süsstrunk, Radhakrishna Achanta

Content aware image re-targeting methods aim to arbitrarily change image aspect ratios while preserving visually prominent features. To determine visual importance of pixels, existing re-targeting schemes mostly rely on grayscale intensity gradient maps. T ...

Microlenses on Bragg Reflectors to Create Iridescent Colors

Hans Peter Herzig, Toralf Scharf

In nature strong colors play an important role in scaring away predators or finding a mate. Often, the strongest and brightest colors arise from coherent scattering and reflection on periodic structures on a length scale of several micro- or nanometers. Un ...
