Fulltext Press touch code: A finger press based screen size independent authentication scheme for smart devices

Ranak MSAN, Azad S, Nor NNHBM, Zamli KZ

PLoS One, 2017;12(10):e0186940.
PMID: 29084262 DOI: 10.1371/journal.pone.0186940

Due to recent advancements and appealing applications, the purchase rate of smart devices is increasing at a higher rate. Parallely, the security related threats and attacks are also increasing at a greater ratio on these devices. As a result, a considerable number of attacks have been noted in the recent past. To resist these attacks, many password-based authentication schemes are proposed. However, most of these schemes are not screen size independent; whereas, smart devices come in different sizes. Specifically, they are not suitable for miniature smart devices due to the small screen size and/or lack of full sized keyboards. In this paper, we propose a new screen size independent password-based authentication scheme, which also offers an affordable defense against shoulder surfing, brute force, and smudge attacks. In the proposed scheme, the Press Touch (PT)-a.k.a., Force Touch in Apple's MacBook, Apple Watch, ZTE's Axon 7 phone; 3D Touch in iPhone 6 and 7; and so on-is transformed into a new type of code, named Press Touch Code (PTC). We design and implement three variants of it, namely mono-PTC, multi-PTC, and multi-PTC with Grid, on the Android Operating System. An in-lab experiment and a comprehensive survey have been conducted on 105 participants to demonstrate the effectiveness of the proposed scheme.

Pius Owoh N, Mahinderjit Singh M

Sensors (Basel), 2020 Jun 09;20(11).
PMID: 32526843 DOI: 10.3390/s20113280

The proliferation of mobile devices such as smartphones and tablets with embedded sensors and communication features has led to the introduction of a novel sensing paradigm called mobile crowd sensing. Despite its opportunities and advantages over traditional wireless sensor networks, mobile crowd sensing still faces security and privacy issues, among other challenges. Specifically, the security and privacy of sensitive location information of users remain lingering issues, considering the "on" and "off" state of global positioning system sensor in smartphones. To address this problem, this paper proposes "SenseCrypt", a framework that automatically annotates and signcrypts sensitive location information of mobile crowd sensing users. The framework relies on K-means algorithm and a certificateless aggregate signcryption scheme (CLASC). It incorporates spatial coding as the data compression technique and message query telemetry transport as the messaging protocol. Results presented in this paper show that the proposed framework incurs low computational cost and communication overhead. Also, the framework is robust against privileged insider attack, replay and forgery attacks. Confidentiality, integrity and non-repudiation are security services offered by the proposed framework.

MyJurnal

Image watermarking embeds identifying information in an image in such a manner that it cannot easily be removed. For the past several years, image digital watermarking has become a necessary element used for hiding secret image and enabling secured communication such as
privacy, confidentiality, authentication and data integrity. Although numerous watermarking schemes are present in grayscale images, the present work focuses on the RGB color image. This study proposed a new hybrid method that would satisfy the essential needs of modern image watermarking. The color image watermarking is based on the 2D Discrete Cosine Transform and Elgamal cryptosystem. The 2D Discrete Cosine Transform depends on the matrix products, while the Elgamal cryptosystem depends on the discrete logarithm problem. The cryptosystem is combined with existing Arnold transform in watermarking algorithm to enhance the security of secret image. Value of Peak Signal to Noise Ratio was taken as performance evaluation parameters. On the whole, the performance evaluation shows that combining the two algorithms improved the performance of image watermarking.

Fulltext Smart Home Privacy Protection Methods against a Passive Wireless Snooping Side-Channel Attack

Nassiri Abrishamchi MA, Zainal A, Ghaleb FA, Qasem SN, Albarrak AM

Sensors (Basel), 2022 Nov 07;22(21).
PMID: 36366261 DOI: 10.3390/s22218564

Smart home technologies have attracted more users in recent years due to significant advancements in their underlying enabler components, such as sensors, actuators, and processors, which are spreading in various domains and have become more affordable. However, these IoT-based solutions are prone to data leakage; this privacy issue has motivated researchers to seek a secure solution to overcome this challenge. In this regard, wireless signal eavesdropping is one of the most severe threats that enables attackers to obtain residents' sensitive information. Even if the system encrypts all communications, some cyber attacks can still steal information by interpreting the contextual data related to the transmitted signals. For example, a "fingerprint and timing-based snooping (FATS)" attack is a side-channel attack (SCA) developed to infer in-home activities passively from a remote location near the targeted house. An SCA is a sort of cyber attack that extracts valuable information from smart systems without accessing the content of data packets. This paper reviews the SCAs associated with cyber-physical systems, focusing on the proposed solutions to protect the privacy of smart homes against FATS attacks in detail. Moreover, this work clarifies shortcomings and future opportunities by analyzing the existing gaps in the reviewed methods.

Fulltext Watermarking techniques used in medical images: a survey

Mousavi SM, Naghsh A, Abu-Bakar SA

J Digit Imaging, 2014 Dec;27(6):714-29.
PMID: 24871349 DOI: 10.1007/s10278-014-9700-5

The ever-growing numbers of medical digital images and the need to share them among specialists and hospitals for better and more accurate diagnosis require that patients' privacy be protected. As a result of this, there is a need for medical image watermarking (MIW). However, MIW needs to be performed with special care for two reasons. Firstly, the watermarking procedure cannot compromise the quality of the image. Secondly, confidential patient information embedded within the image should be flawlessly retrievable without risk of error after image decompressing. Despite extensive research undertaken in this area, there is still no method available to fulfill all the requirements of MIW. This paper aims to provide a useful survey on watermarking and offer a clear perspective for interested researchers by analyzing the strengths and weaknesses of different existing methods.

Mohsin AH, Zaidan AA, Zaidan BB, Albahri AS, Albahri OS, Alsalem MA, et al.

J Med Syst, 2018 Oct 16;42(12):238.
PMID: 30327939 DOI: 10.1007/s10916-018-1104-5

The development of wireless body area sensor networks is imperative for modern telemedicine. However, attackers and cybercriminals are gradually becoming aware in attacking telemedicine systems, and the black market value of protected health information has the highest price nowadays. Security remains a formidable challenge to be resolved. Intelligent home environments make up one of the major application areas of pervasive computing. Security and privacy are the two most important issues in the remote monitoring and control of intelligent home environments for clients and servers in telemedicine architecture. The personal authentication approach that uses the finger vein pattern is a newly investigated biometric technique. This type of biometric has many advantages over other types (explained in detail later on) and is suitable for different human categories and ages. This study aims to establish a secure verification method for real-time monitoring systems to be used for the authentication of patients and other members who are working in telemedicine systems. The process begins with the sensor based on Tiers 1 and 2 (client side) in the telemedicine architecture and ends with patient verification in Tier 3 (server side) via finger vein biometric technology to ensure patient security on both sides. Multilayer taxonomy is conducted in this research to attain the study's goal. In the first layer, real-time remote monitoring studies based on the sensor technology used in telemedicine applications are reviewed and analysed to provide researchers a clear vision of security and privacy based on sensors in telemedicine. An extensive search is conducted to identify articles that deal with security and privacy issues, related applications are reviewed comprehensively and a coherent taxonomy of these articles is established. ScienceDirect, IEEE Xplore and Web of Science databases are checked for articles on mHealth in telemedicine based on sensors. A total of 3064 papers are collected from 2007 to 2017. The retrieved articles are filtered according to the security and privacy of telemedicine applications based on sensors. Nineteen articles are selected and classified into two categories. The first category, which accounts for 57.89% (n = 11/19), includes surveys on telemedicine articles and their applications. The second category, accounting for 42.1% (n = 8/19), includes articles on the three-tiered architecture of telemedicine. The collected studies reveal the essential need to construct another taxonomy layer and review studies on finger vein biometric verification systems. This map-matching for both taxonomies is developed for this study to go deeply into the sensor field and determine novel risks and benefits for patient security and privacy on client and server sides in telemedicine applications. In the second layer of our taxonomy, the literature on finger vein biometric verification systems is analysed and reviewed. In this layer, we obtain a final set of 65 articles classified into four categories. In the first category, 80% (n = 52/65) of the articles focus on development and design. In the second category, 12.30% (n = 8/65) includes evaluation and comparative articles. These articles are not intensively included in our literature analysis. In the third category, 4.61% (n = 3/65) includes articles about analytical studies. In the fourth category, 3.07% (n = 2/65) comprises reviews and surveys. This study aims to provide researchers with an up-to-date overview of studies that have been conducted on (user/patient) authentication to enhance the security level in telemedicine or any information system. In the current study, taxonomy is presented by explaining previous studies. Moreover, this review highlights the motivations, challenges and recommendations related to finger vein biometric verification systems and determines the gaps in this research direction (protection of finger vein templates in real time), which represent a new research direction in this area.

Real-Time Medical Systems Based on Human Biometric Steganography: a Systematic Review

Mohsin AH, Zaidan AA, Zaidan BB, Ariffin SAB, Albahri OS, Albahri AS, et al.

J Med Syst, 2018 Oct 29;42(12):245.
PMID: 30374820 DOI: 10.1007/s10916-018-1103-6

In real-time medical systems, the role of biometric technology is significant in authentication systems because it is used in verifying the identity of people through their biometric features. The biometric technology provides crucial properties for biometric features that can support the process of personal identification. The storage of biometric template within a central database makes it vulnerable to attack which can also occur during data transmission. Therefore, an alternative mechanism of protection becomes important to develop. On this basis, this study focuses on providing a detailed analysis of the extant literature (2013-2018) to identify the taxonomy and research distribution. Furthermore, this study also seeks to ascertain the challenges and motivations associated with biometric steganography in real-time medical systems to provide recommendations that can enhance the efficient use of real-time medical systems in biometric steganography and its applications. A review of articles on human biometric steganography in real-time medical systems obtained from three main databases (IEEE Xplore, ScienceDirect and Web of Science) is conducted according to an appropriate review protocol. Then, 41 related articles are selected by using exclusion and inclusion criteria. Majority of the studies reviewed had been conducted in the field of data-hiding (particularly steganography) technologies. In this review, various steganographic methods that have been applied in different human biometrics are investigated. Thereafter, these methods are categorised according to taxonomy, and the results are presented on the basis of human steganography biometric real-time medical systems, testing and evaluation methods, significance of use and applications and techniques. Finally, recommendations on how the challenges associated with data hiding can be addressed are provided to enhance the efficiency of using biometric information processed in any authentication real-time medical system. These recommendations are expected to be immensely helpful to developers, company users and researchers.

Law on consent and confidentiality in India: a need for clarity

Mathiharan K

Natl Med J India, 2014 Jan-Feb;27(1):39-42.
PMID: 25403126

The concept of informed consent specific to medical research and treatment is still alien to many medical researchers and practitioners and to millions of Indians. The doctor-patient relationship in India is governed more by trust where the doctor is the authoritative person. Therefore, the benefit of informed consent does not reach all patients in day-to-day medical practice. To complicate the issue, the Indian law is not specific about the age at which a person can give valid consent. The Indian Penal Code is silent about the legal validity of consent given by persons between 12 and 18 years of age. Similarly, the age at which the 'Right to Confidentiality' begins is yet to be defined either by the statute or by the courts. Hence, there is a need for a clear statutory provision to remove the anomalies and ambiguities regarding the age of consent to undergo invasive therapeutic or investigative procedures, participate in clinical trials, as well as define the age at which a person's right to medical confidentiality begins.

Design and develop a video conferencing framework for real-time telemedicine applications using secure group-based communication architecture

Mat Kiah ML, Al-Bakri SH, Zaidan AA, Zaidan BB, Hussain M

J Med Syst, 2014 Oct;38(10):133.
PMID: 25199651 DOI: 10.1007/s10916-014-0133-y

One of the applications of modern technology in telemedicine is video conferencing. An alternative to traveling to attend a conference or meeting, video conferencing is becoming increasingly popular among hospitals. By using this technology, doctors can help patients who are unable to physically visit hospitals. Video conferencing particularly benefits patients from rural areas, where good doctors are not always available. Telemedicine has proven to be a blessing to patients who have no access to the best treatment. A telemedicine system consists of customized hardware and software at two locations, namely, at the patient's and the doctor's end. In such cases, the video streams of the conferencing parties may contain highly sensitive information. Thus, real-time data security is one of the most important requirements when designing video conferencing systems. This study proposes a secure framework for video conferencing systems and a complete management solution for secure video conferencing groups. Java Media Framework Application Programming Interface classes are used to design and test the proposed secure framework. Real-time Transport Protocol over User Datagram Protocol is used to transmit the encrypted audio and video streams, and RSA and AES algorithms are used to provide the required security services. Results show that the encryption algorithm insignificantly increases the video conferencing computation time.

Marzo RR, Bhattacharya S, Ravichandran S, Lakshmanan P, Jeffery VR, Moralitheran P, et al.

J Educ Health Promot, 2019;8:250.
PMID: 32002422 DOI: 10.4103/jehp.jehp_192_19

INTRODUCTION: Smoking is one of the leading factors of mortality in Malaysia. Most youngsters start at adolescence, fascinated by the concept of smoking. Interventions that harness the broad availability of mobile phones, as well as adolescents' interest in their appearance, may be an innovative way to advance school-based prevention. This study aims to determine the perceptions of facial-aging apps among secondary school students.
METHODOLOGY: For this research, descriptive cross-sectional study using simple random sampling method was used. Population sampling was targeted toward three government schools. The total number of respondents is 383, with all of them aged between 13 and- 16 years of age. Legal considerations were taken to maintain the confidentiality of respondents. The specific objectives are: 1. To determine the level of change of intention on smoking, 2. To know the perceived reactions of the peer groups on the appearances of students as nonsmokers, 3. To determine whether the students learned new benefits of nonsmokingand, 4. To measure the impact of a facial-aging app among students.
RESULTS: The number of respondents who smoke was 40 (10.4%), while the number of respondents who do not smoke was 343 (89.6%). About 89% of the respondents agree that their three-dimensional selfie image motivates them not to smoke. In addition, 87.8% of respondents admit that the perceived reactions of their classmates make them think that they look better as nonsmokers. After learning the effects of smoking, about 86.4% of the respondents acknowledged that they would educate their peer groups. Furthermore, 85.9% of the respondents found this "Smokerface" app enjoyable.
CONCLUSION: The facial-aging intervention was effective in motivating Malaysian pupils to stay away from tobacco use. Thus, the analysis on the study of facial app usage in smoking prevention among youngsters concludes that most of the adolescents concur that the "Smokerface" app helps in the prevention of smoking among youths.

Fulltext Physical Layer Security Using Two-Path Successive Relaying

Liau QY, Leow CY, Ding Z

Sensors (Basel), 2016 Jun 09;16(6).
PMID: 27294924 DOI: 10.3390/s16060846

Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this is at the price of sophisticated implementation. As an alternative, two-path successive relaying has been proposed to emulate operation of full-duplex relay by scheduling a pair of half-duplex relays to assist the source transmission alternately. However, the performance of two-path successive relaying in secrecy communication remains unexplored. This paper proposes a secrecy two-path successive relaying protocol for a scenario with one source, one destination and two half-duplex relays. The relays operate alternately in a time division mode to forward messages continuously from source to destination in the presence of an eavesdropper. Analytical results reveal that the use of two half-duplex relays in the proposed scheme contributes towards a quadratically lower probability of interception compared to full-duplex relaying. Numerical simulations show that the proposed protocol achieves the ergodic achievable secrecy rate of full-duplex relaying while delivering the lowest probability of interception and secrecy outage probability compared to the existing half duplex relaying, full duplex relaying and full duplex jamming schemes.

Fulltext Using telemedicine to support care for people with type 2 diabetes mellitus: a qualitative analysis of patients' perspectives

Lee JY, Chan CKY, Chua SS, Paraidathathu T, Lee KK, Tan CSS, et al.

BMJ Open, 2019 Oct 22;9(10):e026575.
PMID: 31640990 DOI: 10.1136/bmjopen-2018-026575

OBJECTIVE: Telemedicine has been promoted as an economical and effective way to enhance patient care, but its acceptance among patients in low-income and middle-income countries is poorly understood. This study is aimed to explore the experiences and perspectives of people with type 2 diabetes mellitus that used telemedicine to manage their condition.
DESIGN: In-depth and focus group interviews were conducted with participants who have engaged in telemedicine. Questions included were participants' perception on the programme being used, satisfaction as well as engagement with the telemedicine programme. All interviews and focus groups were audio-recorded and transcribed verbatim. Data were analysed using a thematic approach.
PARTICIPANTS AND SETTING: People with type 2 diabetes (n=48) who participated in a randomised controlled study which examined the use of telemedicine for diabetes management were recruited from 11 primary care clinics located within the Klang Valley.
RESULTS: Twelve focus groups and two in-depth interviews were conducted. Four themes emerged from the analysis: (1) generational difference; (2) independence and convenience, (3) sharing of health data and privacy and (4) concerns and challenges. The main obstacles found in patients using the telemedicine systems were related to internet connectivity and difficulties experienced with system interface. Cost was also another significant concern raised by participants. Participants in this study were primarily positive about the benefits of telemedicine, including its ability to provide real-time data and disease monitoring and the reduction in clinic visits.
CONCLUSION: Despite the potential benefits of telemedicine in the long-term care of diabetes, there are several perceived barriers that may limit the effectiveness of this technology. As such, collaboration between educators, healthcare providers, telecommunication service providers and patients are required to stimulate the adoption and the use of telemedicine.NCT0246680.

MyJurnal

The aim of this study is to examine the factors that drive students’ self-disclosure on Social Networking Sites (SNSs). A total of 215 undergraduates from two public universities in East Malaysia were recruited as respondents. This study adapts self-disclosure model by Elmi, A.Iahad and Ahmed (2012), where the model proposed trust as one of the factors that complementing other existing factors in online self-disclosure. This study proved that privacy concerns (r = -.212, p < .01), perceived trust (r = .22, p < .01), perceived ease of use (r = .213, p < .01), and perceived enjoyment (r = .28, p < .01) are significantly related to students’ online self-disclosure on SNSs. In addition, as trust plays a vital role in moderating the users’ online self-disclosure behavior, this study formulated students’ trusts on SNSs based on three dimensions which are individual, institutional and online trust. Findings of study suggested that there is a significant difference between online trust based on male and female respondents.

Fulltext Grouping and Sponsoring Centric Green Coverage Model for Internet of Things

Kumar V, Kumar S, AlShboul R, Aggarwal G, Kaiwartya O, Khasawneh AM, et al.

Sensors (Basel), 2021 Jun 08;21(12).
PMID: 34201100 DOI: 10.3390/s21123948

Recently, green computing has received significant attention for Internet of Things (IoT) environments due to the growing computing demands under tiny sensor enabled smart services. The related literature on green computing majorly focuses on a cover set approach that works efficiently for target coverage, but it is not applicable in case of area coverage. In this paper, we present a new variant of a cover set approach called a grouping and sponsoring aware IoT framework (GS-IoT) that is suitable for area coverage. We achieve non-overlapping coverage for an entire sensing region employing sectorial sensing. Non-overlapping coverage not only guarantees a sufficiently good coverage in case of large number of sensors deployed randomly, but also maximizes the life span of the whole network with appropriate scheduling of sensors. A deployment model for distribution of sensors is developed to ensure a minimum threshold density of sensors in the sensing region. In particular, a fast converging grouping (FCG) algorithm is developed to group sensors in order to ensure minimal overlapping. A sponsoring aware sectorial coverage (SSC) algorithm is developed to set off redundant sensors and to balance the overall network energy consumption. GS-IoT framework effectively combines both the algorithms for smart services. The simulation experimental results attest to the benefit of the proposed framework as compared to the state-of-the-art techniques in terms of various metrics for smart IoT environments including rate of overlapping, response time, coverage, active sensors, and life span of the overall network.

ScientificWorldJournal, 2013;2013:462826.
PMID: 24285935 DOI: 10.1155/2013/462826

We describe the findings from a survey assessing the beliefs regarding testing, confidentiality, disclosure, and environment of care and attitudes towards care of people with HIV/AIDS (PLHWA), in 1020, 4th and 5th year medical students, from public and private medical universities in Malaysia. A self-administered validated questionnaire based on the UNAIDS Model Questionnaire with a 5-point Likert scale (5, strongly disagree; 4, disagree; 3, neutral; 2, agree; 1, strongly agree) was used as a survey tool. The survey included demographic data and data on undergraduate training received on HIV/AIDS. Statistical significance in the demographic data and training received by respondents was evaluated using the chi-square test while the independent Student's t-test was used for comparison of means between public and private universities. A P value of <0.05 was considered statistically significant with 95% confidence interval. Our study revealed less than 20% of medical students received adequate training to care for PLHWA. They had prevalent negative beliefs regarding testing, confidentiality, disclosure and environment of care towards PLHWA although in giving care to PLHWA, their attitudes were largely positive and nondiscriminatory.
