A methodology to analyze heart data using fuzzy automata1

“…We also plan to extend the event pattern operators supported in our framework, including other EPL operators, such as the every-distinct, repeat, repeat-until, conjunction and disjunction, as well as data windows. Thus, with these new event pattern operators, we will be able to apply the MEdit4CEP-BPCPN to other application domains such as ehealth and distributed environments [44,45]. For instance, the techniques presented in this work can be adapted to detect deviations between a process model and their running instances, using the event logs following the path established by Wang et al in [46].…”

Prioritized Colored Petri Nets (PCPNs) are a well-known extension of plain Petri nets in which transitions can have priorities and the tokens on the places carry data information. In this paper, we propose an extension of the PCPN model with black sequencing transitions (BPCPN). This extension allows us to easily model the ordered firing of the same transition using an ordered set of tokens on one of its precondition places. Black sequencing transitions are then presented as a shorthand notation in order to model the processing of a flow of events, represented by one of their precondition places. We then show how black sequencing transitions can be encoded into PCPNs, and their application to model Complex Event Processing (CEP), defining a compositional approach to translate some of the most relevant event pattern operators. We have developed MEdit4CEP-BPCPN, an extension of the MEdit4CEP tool, to provide tool support for this novel technique, thus allowing end users to easily define event patterns and obtain an automatic translation into BPCPNs. This can, in turn, be transformed into a corresponding PCPN, and then be immediately used in CPN Tools. Finally, a health case study concerning the monitoring of pregnant women is considered to illustrate how the event patterns are created and how the BPCPN and PCPN models are obtained by using the MEdit4CEP-BPCPN tool.

“…While the two key elements of IoT are things and networks, in IoE there are five key concepts: things, networks, people, data and processes [2]. IoT and IoE have proved useful in a myriad of contexts and applications, such as healthcare applications, home automation and resource management, among many others more [3][4][5][6].…”

In recent years, the Internet of Things (IoT) has grown rapidly, as has the number of attacks against it. Certain limitations of the paradigm, such as reduced processing capacity and limited main and secondary memory, make it necessary to develop new methods for detecting attacks in real time as it is difficulty to adapt as has the techniques used in other paradigms. In this paper, we propose an architecture capable of generating complex event processing (CEP) rules for real-time attack detection in an automatic and completely unsupervised manner. To this end, CEP technology, which makes it possible to analyze and correlate a large amount of data in real time and can be deployed in IoT environments, is integrated with principal component analysis (PCA), Gaussian mixture models (GMM) and the Mahalanobis distance. This architecture has been tested in two different experiments that simulate real attack scenarios in an IoT network. The results show that the rules generated achieved an F1 score of .9890 in detecting six different IoT attacks in real time.
