Automatic Emergency Identifier in Mobile for Healthcare

INTRODUCTION

With the pervasiveness of smart phones and the advance of wireless body sensor networks

(BSNs), mobile Healthcare (m-Healthcare), which extends the operation of Healthcare provider

into a pervasive environment for better health monitorin, has attracted considerable interest

recently! However, the flo"rish of m-Healthcare still faces many challenes incl"din

information sec"rity and privacy preservation! #n this paper, we propose a sec"re and privacy-

preservin opport"nistic comp"tin framework, called S$%&, for m-Healthcare emerency! With

S$%&, smart phone reso"rces incl"din comp"tin power and enery can be opport"nistically

athered to process the comp"tin-intensive personal health information ($H#) d"rin m-

Healthcare emerency with minimal privacy disclos"re! #n specific, to leverae the $H# privacy

disclos"re and the hih reliability of $H# process and transmission in m-Healthcare emerency,

we introd"ce an efficient "ser-centric privacy access control in S$%& framework, which is based

on an attrib"te-based access control and a new privacy-preservin scalar prod"ct comp"tation

($$S$&) techni'"e, and allows a medical "ser to decide who can participate in the opport"nistic

comp"tin to assist in processin his overwhelmin $H# data! etailed sec"rity analysis shows

that the proposed S$%& framework can efficiently achieve "ser-centric privacy access control in

m-Healthcare emerency! #n addition, performance eval"ations via extensive sim"lations

demonstrate the S$%&s effectiveness in term of providin hih reliable $H# process and

transmission while minimi*in the privacy disclos"re d"rin m-Healthcare emerency!

+he st"dy of opport"nistic comp"tin has ained the reat interest from the research comm"nity

recently!

+he existin systems introd"ce the opport"nistic comp"tin paradim in wireless sensor network

to solve the problem of storin and exec"tin an application that exceeds the memory reso"rces

available on a sinle sensor node! specially, their sol"tion is based on the idea of partitionin

the application code into a n"mber of opport"nistically cooperatin mod"les, and each node

contrib"tes to the exec"tion of the oriinal application by r"nnin a s"bset of the application

tasks and providin service to the neihborin nodes!

$assarella et al! eval"ate the performance of service exec"tion in opport"nistic comp"tin!

Specifically, they first abstract reso"rces in pervasive comp"tin as services, which are

opport"nistically contrib"ted by providers and invoked by seekers! +hen, they present a complete

analytical model to depict the service invocation process between seekers and providers, and

derive the optimal n"mber of replicas to be spawned on enco"ntered nodes, in order to minimi*e

the exec"tion time and optimi*e the comp"tational and bandwidth reso"rces "sed!

#n xistin System, ccordin to the sensex over the ae of ./ is expected to hit 01 million by

2131, havin do"bled since 2111! Health care expendit"res pro4ected to rise to 5/!67 by 2151!

+he cost of health care for the nations ain pop"lation has become a national concern are

important for "nderstandin how the opport"nistic comp"tin paradim work when reso"rces

available on different nodes can be opport"nistically athered toether to provide richer

f"nctionality, they have not considered the potential sec"rity and privacy iss"es existin in the

opport"nistic comp"tin paradim!

$RO$O!ED !#!TEM

#n o"r proposed S$%& framework aims at the sec"rity and privacy iss"es, and develops a "ser-

centric privacy access control of opport"nistic comp"tin in m-Healthcare emerency! #n this

paper, we propose a new sec"re and privacy preservin opport"nistic comp"tin framework,

called S$%&, to address this challene! With the proposed S$%& framework, each medical "ser

in emerency can achieve the "ser-centric privacy access control to allow only those '"alified

helpers to participate in the opport"nistic comp"tin to balance the hih-reliability of $H#

process and minimi*in $H# privacy disclos"re in m-Healthcare emerency! Specifically, the

main contrib"tions of this paper are threefold! 8 9irst, we propose S$%&, a sec"re and privacy-

preservin opport"nistic comp"tin framework for m-Healthcare emerency! With S$%&, the

reso"rces available on other opport"nistically contacted medical "sers smart phones can be

athered toether to deal with the comp"tin intensive $H# process in emerency sit"ation! Since

the $H# will be disclosed d"rin the process in opport"nistic comp"tin, to minimi*e the $H#

privacy disclos"re, S$%& introd"ces a "ser-centric two-phase privacy access control to only

allow those medical "sers who have similar symptoms to participate in opport"nistic comp"tin!

8 Second, to achieve "ser-centric privacy access control in opport"nistic comp"tin, we present

an efficient attrib"tebased access control and a novel non-homomorphic encryption based

privacy-preservin scalar prod"ct comp"tation ($$S$&) protocol, where the attrib"ted-based

access control can help a medical "ser in emerency to identify other medical "sers, and $$S$&

protocol can f"rther control only those medical "sers who have similar symptoms to participate

in the opport"nistic comp"tin while witho"t directly revealin "sers symptoms! Note that,

altho"h $$S$& protocols have been well st"died in privacy-preservin data minin, yet most of

them are relyin on time-cons"min homomorphic encryption techni'"e! +o the best of o"r

knowlede, o"r novel non-homomorphic encryption based $$S$& protocol is the most efficient

one in terms of comp"tational and comm"nication overheads! 8 +hird, to validate the

effectiveness of the proposed S$%& framework in m-Healthcare emerency, we also develop a

c"stom sim"lator b"ilt in :ava! xtensive sim"lation res"lts show that the proposed S$%&

framework can help medical "sers to balance the hih-reliability of $H# process and minimi*in

the $H# privacy disclos"re in m-Healthcare emerency

#n this mod"le, each mobile medical "sers personal health information ($H#) s"ch as heart beat,

blood s"ar level, blood press"re and temperat"re and others, can be first collected by BSN, and

then areated by smart phone via Bl"etooth! 9inally, they are f"rther transmitted to the remote

healthcare center via 3@ networks! Based on these collected $H# data, medical professionals at

healthcare center can contin"o"sly monitor medical "sers health conditions and as well '"ickly

react to "sers life-threatenin sit"ations and save their lives by dispatchin amb"lance and

medical personnel to an emerency location in a timely fashion!
