The document discusses a personalized sensing system developed for mobile devices aimed at classifying sensory data according to user behavior and device status, emphasizing the importance of data sharing and security. It outlines the framework comprising tagging and sensing modules, an inference module with procedural rules for predictive analytics, and a data-centric networking interface designed for efficient data retrieval. Final considerations include the integration of services, behavioral profiling through data classification, and future testing with various mobile sensors.

Introduction
Theme, Importance and Impact
Study the capacity to perform classification of sensory data from mobile devices, providing
information based on the user behavior and the state of the device.
Impact in mechanisms of transfer
and data sharing;
Concept of searching for data to
meet user;
Learning user behavior based in
mobile sensory data;
Pervasive and Ubiquitous
Computing.
Large-scale, long-lived, mostly
mobile
Not so energy-constrained
Mobility is a driving factor
Security, trust and privacy are
important factors
Connection with emerging
applications;
Sharing data based in users
interests;
Information be available in the
network automatically without user
interaction;
 Sensing people behavior;
Sensing proximity interactions;

4. Develop an middleware
capable to analyze sensory
data from mobile devices,
implementing techniques for
data classification (Sensing
Application) whose learning
will enable the transmission of
inferred information for network
sharing (Networking
Application) based on user’s
behaviors and device state
(Data Tagging)

8. Inference Module
Procedural Rules
Forward chaining
An action is executed when
conditions are satisfied.
Assign values to attributes
Evaluate conditions
Check if all conditions are
satisfied
Supervised Learning
Predictive Modules

Method – PersonalSense
Attributes assign
values - defined
Conditions evaluated
Rules are checked
Actions executed
Method – PersonalSense
A Counter to each rule to detect the
action
Use the action to keep track how many
condition in the rule are currently
satisfied
The rule is ready to fire if all conditions
have become true
The attribute is flagged as defined and
undefined
Gain information model

9. Networking Interface
Data-Centric Characteristics
 Seeks to adapt the network architecture to the
current network usage patterns
 has a founding principle that a communication
network should allow a user to focus on the data
rather than having to reference a specific, physical
location where that data is to be retrieved from.
 Security into the network at the data level
 The name of content sufficiently describes the
information
PersonalSense in Data Centric Networking
Focus on data treatment
Receive data and sent data to an application
User behavior to receive some kind of data
Use a data storage cache at each level of the
network
Decrease the transmission traffic
Increase the speed of response
Allows a simpler configuration of network devices

11. Final Considerations
Service integration and
communication
Automatic provision of
information in the network
relying in opportunistics
meetings between devices
Classification of data
collected from the sensory
capabilities of devices, and
knowledge acquisition and
generation of behavioral
profiles

(Smart Pin, 2009)
Test more mobile sensors
Test the interaction with
Maestroo and ICON in a
mobile device
Test with other classifier
algorithms
Elaboration of an
algorithm for classification
of collected sensor data
from mobile devices
