Steep - Run Scientific Workflows in the Cloud

February, 6th 2020

For the last couple of years, I’ve been work­ing on a sci­entific work­flow man­age­ment sys­tem called Steep. I’m more than happy to an­nounce that, here at Fraunhofer IGD, we de­cided to make Steep Open-Source! You can down­load the bin­ar­ies and the source code of Steep from its Git­Hub re­pos­it­ory.

Dynamic SSE for storing geospatial data in the cloud

May, 20th 2019

Geo­spa­tial data sets of­ten con­tain sens­it­ive in­form­a­tion, for ex­ample, about urban in­fra­struc­tures. Since clouds are usu­ally provided by third parties, this data needs to be pro­tec­ted. In our pa­per en­titled Dy­namic search­able sym­met­ric en­cryp­tion for stor­ing geo­spa­tial data in the cloud, we present an en­cryp­tion scheme al­low­ing users to en­crypt their data in the cloud and make it search­able at the same time. The pa­per has just been pub­lished to the In­ter­na­tional Journal of In­form­a­tion Se­cur­ity by Springer.

Implementing secure applications in smart city clouds using microservices

May, 14th 2019

Smart Cit­ies make use of ICT tech­no­logy to ad­dress the chal­lenges of mod­ern urban man­age­ment. The cloud provides an ef­fi­cient and cost-ef­fect­ive plat­form on which they can man­age, store and pro­cess data, as well as build ap­plic­a­tions per­form­ing com­plex com­pu­ta­tions and ana­lyses. The quickly chan­ging re­quire­ments in a Smart City re­quire flex­ible soft­ware ar­chi­tec­tures that let these ap­plic­a­tions scale in a dis­trib­uted en­vir­on­ment. Smart Cit­ies have to deal with huge amounts of data in­clud­ing sens­it­ive in­form­a­tion about in­fra­struc­ture and cit­izens. In or­der to lever­age the be­ne­fits of the cloud, in par­tic­u­lar in terms of scalab­il­ity and cost-ef­fect­ive­ness, this data should be stored in a pub­lic cloud. However, in such an en­vir­on­ment, sens­it­ive data needs to be en­cryp­ted to pre­vent un­au­thor­ized ac­cess.

I just up­loaded a new acous­tic cover to You­Tube. Damien Rice is one of my fa­vour­ite artists of all time. It’s a won­der I haven’t up­loaded more cov­ers of his songs yet but I will def­in­itely do that in the fu­ture 😊
