SMU’s engineering students to test new virtual reality game to practice solving hands-on infrastructure failure problems

Games let people experience the unknown and unfamiliar in a virtual world, and have the power to engage their users.

SMU’s engineering students will help test a new virtual reality game that will someday be rolled out to classrooms everywhere to help students design, inspect and test geotechnical — soil and rock — systems virtually.

SMU will receive $80,000 in funding as part of a larger $650,000 grant from the National Science Foundation, which was awarded to professors at Rensselaer Polytechnic Institute, Troy, N.Y.

Called Geo Explorer, the game places students in a virtual field-testing experience to learn how to use the instrument and interpret its results, said Usama El Shamy, associate professor, department of civil and environmental engineering, SMU Lyle School of Engineering.

“Nowadays, Students get hands-on lab experiences testing element-level samples in geotechnical engineering classes,” said El Shamy. “When it comes to field testing, they only see images of the instrument and deal with raw test data.”

The game will broaden the learning experience considerably.

“The game is intended to place the students in a virtual environment where they can perform the field test, and gather and interpret its data as they play,” he said.

“Other modules of the game will place the student in the position of an engineer inspecting the integrity of a levee after a rain storm. The student should be able to promptly report any warning signs of potential failure of the levee,” El Shamy said. “Failure to do a timely report would result in failure of the levee, or, in other words, game over.”

Mixed-reality and mobile game virtually brings students into the field with immersive learning
Geo Explorer is a mixed-reality and mobile game to virtually bring students into the field to conduct geotechnical site investigations and evaluations. It’s being developed by Rensselaer civil engineering faculty Tarek Abdoun and Victoria Bennett.

“Geo Explorer has a tremendous potential to teach students about the deadly consequences of deteriorating infrastructure,” Bennett said. “Games let people experience the unknown and unfamiliar in a virtual world, and have the power to engage their users.”

The immersive learning from playing Geo Explorer will let students participate in geotechnical field testing, inspect levees during and after extreme storms, assess stability and make decisions about future actions related to flood-control infrastructure.

El Shamy will test the use of the game in SMU’s undergraduate geotechnical engineering classes, which are part of the Lyle School’s civil engineering program, then provide feedback on the game’s design and impact on intended learning outcomes. Preliminary testing of the game in classes will start in April.

A bridge to the lab, Geo Explorer incorporates testing actual soil samples
Geo Explorer also includes a bridge to the actual laboratory. Players will not only use mobile devices, downloading field data, receiving messages from characters and collaborating with classmates, but will test actual soil samples in the lab and can upload results to the game.

Abdoun and Bennett note that natural disasters such as Hurricane Katrina illustrate the serious consequences of a deteriorating infrastructure and a public ill-equipped to respond to weather extremes.

Such challenges cannot be adequately met in the traditional classroom.

Games like Geo Explorer can address the gaps in geotechnical engineering education by providing realistic virtual experience with the unfamiliar, letting participants weigh choices and experience their consequences.

“Ultimately, Geo Explorer will be available for free and be scaled for use by students from kindergarten through high school, particularly in districts with a high percentage of minorities who are underrepresented in technical fields,” Abdoun said.

Concept opens up possibilities for developing games in other areas of science and technology
Geo Explorer is intended to educate the workforce in science, technology, engineering and math, said Rensselaer’s Shekhar Garde, dean of the School of Engineering.

“Geo Explorer has a great potential to educate students about grand challenges in infrastructure resilience, sustainability and stewardship,” Garde said. “It also opens up possibilities for developing games in other areas of science and technology for a range of applications in human health, including chemical and biological safety.”

Funds will be used to utilize the game in a geotechnical course that integrates Geo Explorer. The project builds on game modules developed by Deltares, an institute for applied research in water, subsurface and infrastructure based in the Netherlands.

Besides SMU and Rensselaer faculty, other partners include Casper Harteveld, Northeastern University; Flora McMartin, Broad-Based Knowledge; and Joseph Tront, Virginia Polytechnic Institute and State University; Manhattan College; and California State University Fullerton. — Southern Methodist University, Rensselaer Polytechnic

CoinDesk: Research — Over $11 Million Lost in Bitcoin Scams Since 2011

The researchers painstakingly read forum threads post by post, even translating messages written in languages other than English.

Bitcoin, SMU, scammers, $11 million, Moore, Vasek

With the cryptocurrency Bitcoin increasingly popular for digital transactions, the digital currency news site CoinDesk covered the research of SMU Bitcoin experts Marie Vasek, lead researcher on the study, and Tyler W. Moore, both in SMU’s Computer Science and Engineering Department in the Lyle School of Engineering.

The study by Vasek and Moore, “There’s no free lunch, even using bitcoin: Tracking the popularity and profits of virtual currency scams,” found that fraudulent schemes have scammed at least $11 million in Bitcoin deposits from unsuspecting cyber customers over the past four years.

Bitcoin is the digital world’s most popular virtual currency, with millions in circulation.

The study is the first empirical study of its kind. Vasek and Moore found that hucksters used four different types of schemes through authentic-looking web-based investment and banking outlets to lure customers and heist deposits.

Vasek explained to CoinDesk journalist Joon Ian Wong how the researchers extracted Bitcoin addresses linked to the frauds, enabling them to look at transactions from victims to fraudsters recorded on the transaction addresses.

Scams promising bitcoin riches have netted swindlers at least $11m in the last four years, researchers have found.

Some 13,000 victims handed over their money unwittingly in 42 different scams over that time period, their data suggests.

However, the total amount of funds cheated from victims over this period is almost certainly higher than the estimated $11m the research identified.

A co-author of the research, Marie Vasek, said:

“There are a lot of scams that we couldn’t measure at all. There were scams we couldn’t find or verify … We think presenting our findings as they are, a lower bound, makes a lot of room for us and others to further quantify scams in this space.”

Vasek, who researches computer security at Southern Methodist University, co-wrote the paper with Tyler Moore, an assistant professor in computer science at the same institution.

Painstaking search
The paper, titled There’s No Free Lunch, Even Using Bitcoin: Tracking the Popularity and Profits of Virtual Currency Scams, has been presented at the Financial Cryptography and Data Security conference taking place in Puerto Rico this week.

Vasek and Moore combed online repositories of scam accusations, including a mega-thread of scams, hacks and heists on the Bitcointalk forum that has been maintained since 2012, as well as the subreddit r/bitcoin, BadBitcoin.org and CryptoHYIPs.com.

This process required the researchers to painstakingly go through forum threads post by post, even translating messages that were written in languages other then English, as well as visiting the websites that scammers created to publicise themselves.

“We went through every single post to determine if the scheme was a scam, any associated bitcoin addresses with the scheme, and any associated scams,” Vasek said.

Using this method they found 349 scams, which were then whittled down to 192 deceptions after excluding phishing, malware and pay-for-click websites, which fall outside the scope of the study.

$2.5 million awarded to Retina Foundation and SMU Lyle to study macular degeneration

Research partners in collaborative venture will help rapidly prototype new diagnostic and clinical treatment approaches

An example of the impaired vision of a person suffering with macular degeneration.
Vision impaired by age-related macular degeneration, a progressive, degenerative disease of the retina and the most common cause of vision loss for people over 50.

The Retina Foundation of the Southwest and SMU’s Bobby B. Lyle School of Engineering will collaborate to create the Clinical Center of Innovation for Age-Related Macular Degeneration.

Supported by a $2.5 million grant award from the W. W. Caruth, Jr. Foundation at Communities Foundation of Texas (CFT), the center will be housed at the Retina Foundation in Dallas.

The new collaborative venture will help to rapidly prototype new diagnostic and clinical treatment approaches, focusing on the specific needs of patients who are losing their vision to age-related macular degeneration.

Physician Karl Csaky, Chief Medical Director and T. Boone Pickens Senior Scientist at the Retina Foundation of the Southwest, will lead the joint venture, along with Marc Christensen, Dean of SMU’s Lyle School of Engineering.

Age-related macular degeneration is a progressive, degenerative disease of the retina and is the most common cause of vision loss for individuals 50 years and older. Currently, there are 18 million Americans who have some form of age-related macular degeneration.

It is projected that the population over the age of 60 will double by the year 2030, which will dramatically increase the number of individuals affected by this disease. At present there are few effective treatments for the majority of patients who suffer from age-related macular degeneration.

“I am extremely thankful to the Caruth Foundation for providing their generous support for a unique approach to help patients with age-related macular degeneration,” said Dr. Csaky. “This one of a kind initiative will focus on leveraging the strengths of two preeminent Dallas institutions.”

This $2.5 million award from the W. W. Caruth, Jr. Foundation at CFT recognizes the great need to develop an innovative approach to medical research for age-related macular degeneration, adapting new technologies and treatments that directly correlate to the patients’ disease state. “This type of unique partnership between a top engineering school and a clinical research organization has the potential to be replicated in other areas of medicine as well,” said Brent Christopher, President and CEO of Communities Foundation of Texas. “This model of pairing disparate disciplines to tackle challenging medical issues is the transformational approach Will Caruth would have championed.”

Since 1982, the Retina Foundation of the Southwest has been on the leading edge of basic research to better understand age-related macular degeneration and how it works to destroy central vision, which is necessary for reading, writing and driving. The Foundation also works closely with patients in a clinical setting to better understand the vision loss they are experiencing over time.

SMU’s Lyle School of Engineering is dedicated to the role of innovation in finding solutions to real-world problems and has a dedicated space for those pursuits – the Deason Innovation Gymnasium. The Lyle School will help to accelerate the clinical application of technologies.

“We are grateful for this opportunity to collaborate with Retina Foundation doctors to help develop and prototype treatments tailored to patient needs,” said Christensen. “For example, we’ll be in a position to tackle problems such as the delivery of medication to the retina through polymer chemistry and mechanical engineering. Engineering and medicine can partner in astounding ways, and we are excited to see how our framework for fostering innovation accelerates solutions to medical challenges.”

Bitcoin scams steal at least $11 million in virtual deposits from unsuspecting customers

First empirical study of its kind identifies fraud on seemingly legitimate web sites purposely designed to steal customers’ funds

bitcoin, moore, smu, fraud

Fraudulent schemes have scammed at least $11 million in Bitcoin deposits from unsuspecting cyber customers over the past four years, according to new cyber security research from Southern Methodist University, Dallas.

Bitcoin is the digital world’s most popular virtual currency, with millions in circulation.

In the first empirical study of its kind, SMU researchers found that hucksters used four different types of schemes through authentic-looking web-based investment and banking outlets to lure customers and heist deposits, said computer security expert Marie Vasek, lead researcher on the study.

“Our calculation of $11 million is almost certainly at the low-end,” said Vasek. “The amount of Bitcoin that depositors have lost to these scams is probably many millions more.”

Typically the scams succeed by exploiting not only people’s greed, but also the urge to “get rich quick,” coupled with the inability to judge the legitimacy of web services to decide which financial sites are good or bad, said Bitcoin and cyber security expert Tyler W. Moore, co-researcher on the study.

“Because the complete history of Bitcoin transactions are made public, we have been able to inspect, for the first time, the money flowing in and out of fraudulent schemes in great detail. It’s like having access to all of Bernie Madoff’s books for many of these scams,” said Moore, director of the Economics and Social Sciences program of the Darwin Deason Institute for Cyber Security in SMU’s Lyle School of Engineering.

13,000 victims and counting in four different kinds of scams
The researchers identified 41 scams occurring between 2011 and 2014, in which fraudulent sites stole Bitcoin from at least 13,000 victims, and most certainly more.

“We found that the most successful scams draw the vast majority of their revenue from a few victims,” Vasek said.

The researchers were only able to track revenues for about 21 percent of the scams, which would indicate that the amount of Bitcoin actually stolen most likely far exceeds $11 million.

The findings emerged when the researchers ran a Structured Query Language database dump of all relevant Bitcoin transactions, then analyzed Bitcoin addresses (the account numbers) of both victims and the siphoning transactions of scammers.

The researchers presented the findings, “There’s no free lunch, even using bitcoin: Tracking the popularity and profits of virtual currency scams,” at the 2015 19th International Financial Cryptography and Data Security Conference, Jan. 26-30, in San Juan, Puerto Rico. Vasek is a graduate student in the Lyle School’s Computer Science and Engineering Department. Moore is assistant professor in the Lyle School’s Computer Science and Engineering Department.

“The amount of fraud being attracted by Bitcoin is a testament to the fact the virtual currency is gaining in legitimacy,” said Moore. “But scams that successfully hijack funds from depositors may end up scaring away consumers who will fear using Bitcoin for their legitimate digital transactions.”

There are 13.7 million Bitcoin in circulation, according to blockchain.info. The number of Bitcoin transactions exceeds 100,000 per day.

The research was partially funded by the U.S. Department of Homeland Security’s Science and Technology Directorate, Cyber Security Division, and the Government of Australia and SPAWAR Systems Center Pacific.

Four scams, each with varying lifespans, strategies and success
Vasek and Moore identified four common scams by tracking forum discussions, where scams are often initially advertised and later exposed, and by tracking web sites.

High-yield investment programs, otherwise known as online Ponzi schemes, which promise investors outlandish interest rates on deposits. The scammers lure both unsuspecting victims as well as those fully aware it’s a Ponzi scheme who hope to cash out in time. Of all the scams, this type has taken in the lion’s share of money from victims. The biggest of these scammers was Bitcoin Savings & Trust, formerly First Pirate Savings & Trust. When such schemes collapse, as they eventually do, and often within about 37 days, they’re replaced with a new program, often run by the same criminals, say the researchers. These scammers consistently pay out to their investors far less than they take in.

Mining investment scams are classic advanced-fee fraud, taking orders and money from customers but never delivering any mining equipment — specialized computer processors and electronic devices for mining Bitcoin. These retailers typically endure for 145 days, much longer than Ponzi schemes. Vasek and Moore looked at Labcoin, Active Mining Corp., AsicMiningEuipment.com and Dragon-Miner.com.

Victims make deposits into scam wallets under the promise the service offers greater transaction anonymity. If the deposit is small, scammers leave the money, but if it rises above a threshold, scammers move the money into their wallet. Services such as Onion Wallet, Easy Coin and Bitcoinwallet.in each surfaced with transfers from victims siphoned to one address held by a scammer.

Exchange scams, such as BTC Promo, CoinOpend and Ubitex, offer PayPal and credit card processing, but at a better exchange rate than competitors. Customers soon find out, however, they never get Bitcoin or cash after making payment. Longer-lived exchange scams survived about three months. Wallet and exchange scams exploit the difficulty in judging the legitimacy of web services.

The study is not a comprehensive review, the researchers note, as they were limited to those scams for which they could determine a minimum estimate of the prevalence and criminal profits of the scams after analyzing the public ledger of all Bitcoin transactions ever executed.

The researchers conservatively estimate that $11 million has been taken by scams, while only $4 million has ever been returned. Most of the successful scams catch a few “big fish,” say the researchers, who pay the bulk of the money into the scam.

“Bitcoin scams pose a problem for more than the victims who directly lose money,” Moore said. “They threaten to undermine trust in this promising technology, and cast a chilling effect on those interested in trying out new services. By mining the public record for fraudulent transactions, we hope to deter would-be scammers and assist law enforcement in cracking down on the bad actors.” — Margaret Allen

KERA: Bitcoin — Behind The Cryptocurrency Curtain

“It’s like any other digital commodity in that it finds its value in the people who use it…” — Tyler Moore

Bitcoin, KERA, Tyler Moore, SMU, ponzi scheme

KERA Public Radio journalist Justin Martin tapped the expertise of SMU Bitcoin and cybersecurity expert Tyler W. Moore, an assistant professor of computer science in the Lyle School of Engineering.

An expert on the digital currency Bitcoin, Moore’s expertise draws in part on his research surrounding Bitcoin, the exchanges that trade in the currency and patterns of online usage. One of Moore’s studies found that online money exchanges that trade hard currency for the rapidly emerging cyber money have a 45 percent chance of failing — often taking their customers’ money with them.

The finding is from a computer science study in which Moore applied survival analysis to examine the factors that prompt Bitcoin currency exchanges to close.

KERA’s interview with Moore, “Bitcoin: Behind The Cryptocurrency Curtain,” was published online Nov. 17.

Listen to the interview.

EXCERPT:

By Justin Martin
KERA

Fans of bitcoin tout the digital currency as secure, anonymous and efficient. But wildly fluctuating exchange rates and charges recently in an alleged bitcoin Ponzi scheme in North Texas have put a spotlight on bitcoin’s risks.

Tyler Moore is an assistant professor of computer science and engineering at Southern Methodist University and he joins KERA’s Justin Martin for a conversation on bitcoin.

Interview Highlights: Tyler Moore …

… On bitcoin and cryptocurrency:

“Bitcoin is a currency just like dollars or euros or pounds, but it’s completely digital so there’s no paper equivalent. To do that, you need to have some rules in place so that people can’t willy-nilly copy the bits and steal each other’s bitcoins – so that’s where the crypto comes in – you have some cryptography to protect against double spending and sort of enforce the rules of the system.”

… On how to acquire bitcoin:

“So there’s two main ways – the more esoteric way is to mine bitcoins, but if you’re new to bitcoin the most common way is to go to a currency exchange, just like you would when you enter a new country, go the airport, go to the exchange, and provide your dollars and get whatever currency you’d like. You can get to an online currency exchange and pay your dollars and whatever the current market rate is they’ll give you the equivalent in bitcoin.”

… On bitcoin’s value:

“It’s like any other digital commodity in that it finds its value in the people who use it. Which is one reason we see these huge fluctuations in that there can be wildly differing demands for the currency at a given time.”
