Pattern discovery in large binary relations has been extensively studied. Typically, it needs to compute patterns that hold in relations Objects×Properties that denote whether given properties are satisfied or not by given objects. An emblematic success in this area concerns frequent itemset mining and its post-processing that derives association rules. It is however clear that many datasets co...

Nowadays, the growing necessity for secure and private off-site storage motivates the appearance of novel storage infrastructures. In this sense, it is increasingly common to find storage systems where users interact just with a set of trustworthy participants, such as in Friend-to-Friend (F2F) networks. In general, these systems have been treated as a particular case of P2P networks where link...
