Security most important to retaining mobile banking customers, NTU-WeBank study finds

Service quality and system quality rank second and thirdCredit: NTU Singapore A study by a research team from Nanyang Technological

A study by a research team from Nanyang Technological University, Singapore (NTU Singapore) and China’s first digital-only bank WeBank has found that security, service quality and system quality are the most important factors for customers who use mobile banking.

Two in five respondents (40%) said that the security they felt while carrying out transactions on mobile applications was their most important consideration.

This was followed by the level of service quality (25%), which referred to whether the banking applications could fulfil users’ needs, such as carrying out transactions and easy access to credit card services.

System quality, which considers the performance of the application, including compatibility with different mobile phones and loading speeds, came in a close third (24%).

The results of the study were published in the Journal of Retailing and Consumer Services, an academic publication by Elsevier, last December.

The researchers said their study which ranked factors that are important in determining customer loyalty would be useful to financial institutions who are looking at improving their mobile banking applications.

Already widely used in China prior to COVID-19, mobile banking applications have seen a sharp rise in uptake throughout Asia during the pandemic, as the touchless payment systems provided by most mobile banking applications have gained traction.

The NTU-WeBank team obtained their results after surveying 224 mobile banking users of a large bank in China in 2019. Over three-quarters of the respondents (79%) were frequent users of mobile banking, meaning that they used it at least once a week.

The researchers said that although the study was conducted in China, the results are applicable to other countries where mobile banking has a high level of adoption, such as Singapore, Thailand, and Vietnam.

Associate Professor Xu Hong, from NTU’s School of Social Sciences who led the study, said: “It was already known that all these factors: security, service quality, system quality, and interface design had an impact on customers, and this study highlights implications for banks’ strategies for retaining their mobile banking users, as well as exploring how to capture new customers.”

Assistant Professor Yu Han, from NTU’s School of Computer Science and Engineering, who co-led the research, said: “Our study has implications for banks’ strategies for retaining their mobile banking users, as well as exploring how to capture new customers.”

Assoc Prof Xu and Asst Prof Yu are part of the team at the Joint NTU-WeBank Research Centre on Fintech which initiated this study. The joint centre was launched in early 2019 with the aim of developing new technologies to support Banking 4.0, where banking can be personalised and done anytime, anywhere.

Mr Joe Chen, Executive Vice President of WeBank, said: “The findings are relevant to other banks who are increasingly rolling out more digital solutions, which include payment, lending, and wealth management applications. As mobile banking worldwide is becoming increasingly accepted as replacement for branch-based banking in many countries, it is important for banks to know the factors that affect and influence customer loyalty. In this regard, the Joint NTU-WeBank Research Centre will continue to generate research outcomes and innovations for the benefit of the Fintech industry.”

NTU Senior Vice President (Research) Professor Lam Khin Yong, added: “The NTU-WeBank partnership is another example of the University’s strong links with the private sector. It also shows our strong support for industry collaborations that accelerates the translation of research into innovation and commercial adoption. This study also serves as a good example of interdisciplinary research involving faculty from the social sciences and computer science, as it solves a very important issue in today’s fintech industry.”

A multi-pronged approach to build customer loyalty

The team’s analysis of the results also showed that a mobile application’s interface design had a strong and positive impact on respondents’ evaluation of system and service quality.

This is despite it scoring relatively low compared to other factors surveyed in the study. For example, the team found that respondents tended to associate good interface design, such as smooth transitions between pages, with optimal system quality and high security.

The findings also outlined a larger correlation between several factors that were surveyed. For example, service and system quality and interface design were found to be important in sparking user loyalty, which the researchers defined as “the intention to continuously use the mobile banking product and recommend it to others.”

After analysing the survey results, the team advised that mobile banking operators should focus on providing multi-level security features to increase the users’ sense of security when using the applications.

Such features might include pop-up messages that alert users to the potential risks that could occur when using mobile banking services, as well as a well-documented policy statement from the financial institution.

Besides providing users assurance of their security while using the applications, Assoc Prof Xu added: “The level of service quality, which encompasses factors such as the levels of reliability, responsiveness, and empathy from bank staff, could enhance users’ satisfaction and increase their usage of mobile banking services.”

“By providing a stable and secure mobile banking system that boasts fast responses and efficient service, banks can encourage customers to continue using their mobile banking application, while ultimately strengthening user loyalty. The results can also help improve their overall mobile banking strategy and cater the functions of their apps to the needs of different age groups.”

Next steps: overseas studies

To further their research on loyalty intention in mobile banking, the NTU-WeBank team is looking to conduct studies in other countries and regions to identify other determinants that could affect customer loyalty.

Assoc Prof Xu said the team will continue to leverage the computing platform which it has developed to collect and analyse user experience data for future studies.

“We believe the large-scale immersive studies we will conduct using our computing platform powered by social computing and social media technologies will be able to help banks gain more insights into customers’ intentions,” said Assoc Prof Xu.

The new game, Fakey, emulates a social media feed and teaches users to recognize credible content

Abu Dhabi, UAE, April 27, 2021: As people around the world increasingly get their news from social media, online misinformation has emerged as an area of great concern. To improve news literacy and reduce the spread of misinformation, NYUAD Center for Cybersecurity researcher and lead author Nicholas Micallef is part of a team that designed Fakey, a game that emulates a social media news feed and prompts players to use available signals to recognize and scrutinize suspicious content and focus on credible information. Players can share, like, or fact-check individual articles.

In a new study, Fakey: A Game Intervention to Improve News Literacy on Social Media published in the ACM Digital Library, Micallef and his colleagues Mihai Avram, Filippo Menczer, and Sameer Patil from the Luddy School of Informatics, Computing, and Engineering, Indiana University, present the analysis of interactions with Fakey, which was released to the general public as a web and mobile app with data procured after 19 months of use. Interviews were conducted to verify player understanding of the game elements. The researchers found that the more players interacted with articles in the game, the better their skills at spotting credible content became. However, playing the game did not affect players’ ability to recognize questionable content. Further research will help determine how much gameplay would be necessary to be able to distinguish between legitimate and questionable content.

Games like Fakey, which was designed and developed by researchers at Indiana University, could be offered as a tool to social media users. For example, social media platforms could conduct regular exercises (akin to ‘phishing drills’ used in organizations for employee security training) wherein users practice identifying questionable articles. Or, the researchers say, such games could be integrated into media literacy curricula in schools. “The impact of misinformation could be substantially reduced if people were given tools to help them recognize and ignore such content,” said Micallef. “The principles and mechanisms used by Fakey can inform the design of social media functionality in a way that empowers people to distinguish between credible and fake content in their news feeds and increase their digital literacy.”

The science of sound, vibration to better diagnose, treat brain diseases

Multidisciplinary researchers uncover new ways to use ultrasound energy to image and treat hard-to-reach areas of brainCredit: Allison Carter, Georgia

Multidisciplinary researchers uncover new ways to use ultrasound energy to image and treat hard-to-reach areas of brain

A team of engineering researchers at the Georgia Institute of Technology hopes to uncover new ways to diagnose and treat brain ailments, from tumors and stroke to Parkinson’s disease, leveraging vibrations and ultrasound waves.

The five-year, $2 million National Science Foundation (NSF) project initiated in 2019 already has resulted in several published journal articles that offer promising new methods to focus ultrasound waves through the skull, which could lead to broader use of ultrasound imaging — considered safer and less expensive than magnetic resonance imaging (MRI) technology.

Specifically, the team is researching a broad range of frequencies, spanning low frequency vibrations (audio frequency range) and moderate frequency guided waves (100 kHz to 1 MHz) to high frequencies employed in brain imaging and therapy (in the MHz range).

“We’re coming up with a unique framework that incorporates different research perspectives to address how you use sound and vibration to treat and diagnose brain diseases,” explained Costas Arvanitis, an assistant professor in Georgia Tech’s George W. Woodruff School of Mechanical Engineering and the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. “Each researcher is bringing their own expertise to explore how vibrations and waves across a range of frequencies could either extract information from the brain or focus energy on the brain.”

Accessing the Brain Is a Tough Challenge

While it is possible to treat some tumors and other brain diseases non-invasively if they are near the center of the brain, many other conditions are harder to access, the researchers say.

“The center part of the brain is most accessible; however, even if you are able to target the part of the brain away from the center, you still have to go through the skull,” Arvanitis said.

He added that moving just 1 millimeter in the brain constitutes “a huge distance” from a diagnostic perspective. The science community widely acknowledges the brain’s complexity, each part associated with a different function and brain cells differing from one to the other.

According to Brooks Lindsey, a biomedical engineering assistant professor at Georgia Tech and Emory, there is a reason why brain imaging or therapy works well in some people but not in others.

“It depends on the individual patient’s skull characteristics,” he said, noting that some people have slightly more trabecular bone ? the spongy, porous part of the bone ? that makes it more difficult to treat.

Using ultrasound waves, the researchers are tackling the challenge on multiple levels. Lindsey’s lab uses ultrasound imaging to assess skull properties for effective imaging and therapy. He said his team conducted the first investigation that uses ultrasound imaging to measure the effects of bone microstructure — specifically, the degree of porosity in the inner, trabecular bone layer of the skull.

“By understanding transmission of acoustic waves through microstructure in an individual’s skull, non-invasive ultrasound imaging of the brain and delivery of therapy could be possible in a greater number of people,” he said, explaining one potential application would be to image blood flow in the brain following a stroke.

Refocusing Ultrasound Beams on the Fly

Arvanitis’ lab recently found a new way to focus ultrasound through the skull and into the brain, which is “100-fold faster than any other method,” Arvanitis said. His team’s work in adaptive focusing techniques would allow clinicians to adjust the ultrasound on the fly to focus it better.

“Current systems rely a lot on MRIs, which are big, bulky, and extremely expensive,” he said. “This method lets you adapt and refocus the beam. In the future this could allow us to design less costly, simpler systems, which would make the technology available to a wider population, as well as be able to treat different parts of the brain.”

Using ‘Guided Waves’ to Access Periphery Brain Areas

Another research cohort, led by Alper Erturk, Woodruff Professor of Mechanical Engineering at Georgia Tech, and former Georgia Tech colleague Massimo Ruzzene, Slade Professor of Mechanical Engineering at the University of Colorado Boulder, performs high-fidelity modeling of skull bone mechanics along with vibration-based elastic parameter identification. They also leverage guided ultrasonic waves in the skull to expand the treatment envelope in the brain. Erturk and Ruzzene are mechanical engineers by background, which makes their exploration of vibrations and guided waves in difficult-to-reach brain areas especially fascinating.

Erturk noted that guided waves are used in other applications such as aerospace and civil structures for damage detection. “Accurate modeling of the complex bone geometry and microstructure, combined with rigorous experiments for parameter identification, is crucial for a fundamental understanding to expand the accessible region of the brain,” he said.

Ruzzene compared the brain and skull to the Earth’s core and crust, with the cranial guided waves acting as an earthquake. Just as geophysicists use earthquake data on the Earth’s surface to understand the Earth’s core, so are Erturk and Ruzzene using the guided waves to generate tiny, high frequency “earthquakes” on the external surface of the skull to characterize what comprises the cranial bone.

Trying to access the brain periphery via conventional ultrasound poses added risks from the skull heating up. Fortunately, advances such as cranial leaky Lamb waves increasingly are recognized for transmitting wave energy to that region of the brain.

These cranial guided waves could complement focused ultrasound applications to monitor changes in the cranial bone marrow from health disorders, or to efficiently transmit acoustic signals through the skull barrier, which could help access metastases and treat neurological conditions in currently inaccessible regions of the brain.

Ultimately, the four researchers hope their work will make full brain imaging feasible while stimulating new medical imaging and therapy techniques. In addition to transforming diagnosis and treatment of brain diseases, the techniques could better detect traumas and skull-related defects, map the brain function, and enable neurostimulation. Researchers also see the potential for uncovering ultrasound-based blood-brain barrier openings for drug delivery for managing and treating diseases such as Alzheimer’s.

With this comprehensive research of the skull-brain system, and by understanding the fundamentals of transcranial ultrasound, the team hopes to make it more available to even more diseases and target many parts of the brain.

Nontoxic, flexible energy converters could power wearable devices

Nontoxic, nanotube-based thermoelectric generation converts uneven heat distribution from wearables to electrical energy for their next cycle of operation.

WASHINGTON, April 27, 2021 — A wide variety of portable and wearable electronics have become a large part of our daily lives, so a group of Stanford University researchers wondered if these could be powered by harvesting electricity from the waste heat that exists all around us.

Further inspiration came from a desire to ultimately fabricate energy converting devices from the same materials as the active devices themselves, so they can blend in as an integral part of the total system. Today, many biomedical nanodevices’ power supplies come from several types of batteries that must be separated from the active portion of the systems, which is not ideal.

In Applied Physics Letters, from AIP Publishing, the researchers report the design and fabrication of single-wall carbon nanotube thermoelectric devices on flexible polyimide substrates as a basis for wearable energy converters.

“Carbon nanotubes are one-dimensional materials, known for good thermoelectric properties, which mean developing a voltage across them in a temperature gradient,” said Eric Pop, a professor of electrical engineering and materials science. “The challenge is that carbon nanotubes also have high thermal conductivity, meaning it’s difficult to maintain a thermal gradient across them, and they have been hard to assemble them into thermoelectric generators at low cost.”

The group uses printed carbon nanotube networks to tackle both challenges.

“For example, carbon nanotube spaghetti networks have much lower thermal conductivity than carbon nanotubes taken alone, due to the presence of junctions in the networks, which block heat flow,” Pop said. “Also, direct printing such carbon nanotube networks can significantly reduce their cost when they are scaled up.”

Thermoelectric devices generate electric power locally “by reusing waste heat from personal devices, appliances, vehicles, commercial and industrial processes, computer servers, time-varying solar illumination, and even the human body,” said Hye Ryoung Lee, lead author and a research scientist.

“To eliminate hindrances to large-scale application of thermoelectric materials — toxicity, materials scarcity, mechanical brittleness — carbon nanotubes offer an excellent alternative to other commonly used materials,” Lee said.

The group’s approach demonstrates a path to using carbon nanotubes with printable electrodes on flexible polymer substrates in a process anticipated to be economical for large-volume manufacturing. It is also “greener” than other processes, because water is used as the solvent and additional dopants are avoided.

Flexible and wearable energy harvesters can be embedded into fabrics or clothes or placed on unusual shapes and form factors.

“In contrast, traditional thermoelectrics that rely on bismuth telluride are brittle and stiff, with limited applications,” Pop said. “Carbon-based thermoelectrics are also more environmentally friendly than those based on rare or toxic materials like bismuth and tellurium.”

The most important concept in the group’s work is to “recycle energy as much as we can, converting uneven heat distribution to electrical energy for use for the next cycle of operation, which we demonstrated by using nontoxic nanotube-based thermoelectric generation,” said Yoshio Nishi, a professor of electrical engineering. “This concept is in full alliance with the world’s goal of reducing our total energy consumption.”
