The PreNotiS (preventive notification system) was proposed to address the current lack in consumer prevention and
disaster informatics systems. The underscore of this letter is to propose PreNotiS as a provision of trusted proxies of
information sourcing to be integral to the disaster informatics framework. To promote loose coupling among subsystems,
PreNotiS has evolved into a model-view-controller (MVC) architecture via object-oriented incremental prototyping. The
MVC specifies how all subsystems and how they interact with each other.
A testing framework is also proposed for the PreNotiS to verify multiple concurrent user access which might be
observable during disasters. The framework relies on conceptually similar self-test modules to help with serviceability.
Modern mobile devices are some of the most technologically advanced devices that people use on a daily basis and the
current trends indicate continuous growth in mobile phone applications. Nowadays phones are equipped with cameras
that can capture still images and video, they are equipped with software that can read, convert, manipulate, communicate
and save multimedia in multiple formats. This tremendous progress increased the volumes of communicated sensitive
information which should be protected against unauthorized access. This paper discusses two general approaches for
data protection, steganography and cryptography, and demonstrates how to integrate such algorithms with a mobile-toserver
link being used by many applications.
The tasks achievable by mobile handsets continuously exceed our imagination. Statistics show that the mobile phone
sales are soaring, rising exponentially year after year with predictions being that they will rise to a billion units in 2009,
with a large section of these being smartphones. Mobile service providers, mobile application developers and researchers
have been working closely over the past decade to bring about revolutionary and hardware and software advancements
in hand-sets such as embedded digital camera, large memory capacity, accelerometer, touch sensitive screens, GPS, Wi-
Fi capabilities etc. as well as in the network infrastructure to support these features.
Recently we presented a multi-platform, massive data collection system from distributive sources such as cell phone
users1 called PreNotiS. This technology was intended to significantly simplify the response to the events and help e.g.
special agencies to gather crucial information in time and respond as quickly as possible to prevent or contain potential
emergency situations and act as a massive, centralized evidence collection mechanism that effectively exploits the
advancements in mobile application development platforms and the existing network infrastructure to present an easy-touse,
fast and effective tool to mobile phone users. We successfully demonstrated the functionality of the client-server
application suite to post user information onto the server.
This paper presents a new version of the system PreNotiS, with a revised client application and with all new server
capabilities. PreNotiS still puts forth the idea of having a fast, efficient client-server based application suite for mobile
phones which through a highly simplified user interface will collect security/calamity based information in a structured
format from first responders and relay that structured information to a central server where this data is sorted into a
database in a predefined manner. This information which includes selections, images and text will be instantly available
to authorities and action forces through a secure web portal thus helping them to make decisions in a timely and prompt
manner. All the cell phones have self-localizing capability according to FCC E9112 mandate, thus the communicated
information can be further tagged automatically by location and time information at the server making all this
information available through the secure web-portal.
We present a fast massive information communication system for data collection from distributive sources such as cell
phone users. As a very important application one can mention preventive notification systems when timely notification
and evidence communication may help to improve safety and security through wide public involvement by ensuring
easy-to-access and easy-to-communicate information systems. The technology significantly simplifies the response to
the events and will help e.g. special agencies to gather crucial information in time and respond as quickly as possible.
Cellular phones are nowadays affordable for most of the residents and became a common personal accessory. The paper
describes several ways to design such systems including existing internet access capabilities of cell phones or
downloadable specialized software. We provide examples of such designs. The main idea is in structuring information in
predetermined way and communicating data through a centralized gate-server which will automatically process
information and forward it to a proper destination. The gate-server eliminates a need in knowing contact data and
specific local community infrastructure. All the cell phones will have self-localizing capability according to FCC E911
mandate, thus the communicated information can be further tagged automatically by location and time information.
