Heartbeat could be used as password to access electronic health records

March 7, 2017

Researchers at Binghamton University, State University of New York have devised a new way to protect personal electronic health records using a patient’s own heartbeat.

“The cost and complexity of traditional encryption solutions prevent them being directly applied to telemedicine or mobile healthcare. Those systems are gradually replacing clinic-centered healthcare, and we wanted to find a unique solution to protect sensitive personal health data with something simple, available and cost-effective,” said Zhanpeng Jin, assistant professor in the Department of Electrical and Computer Engineering at the Thomas J. Watson School of Engineering and Applied Science at Binghamton University. Jin is the co-author of a new paper titled “A Robust and Reusable ECG-based Authentication and Data Encryption Scheme for eHealth Systems.”

Traditional security measures — like cryptography or encryption — can be expensive, time-consuming, and computing-intensive. Binghamton researchers encrypted patient data using a person’s unique electrocardiograph (ECG) — a measurement of the electrical activity of the heart measured by a biosensor attached to the skin — as the key to lock and unlock the files.

“The ECG signal is one of the most important and common physiological parameters collected and analyzed to understand a patient’s’ health,” said Jin. “While ECG signals are collected for clinical diagnosis and transmitted through networks to electronic health records, we strategically reused the ECG signals for the data encryption. Through this strategy, the security and privacy can be enhanced while minimum cost will be added.”

Essentially, the patient’s heartbeat is the password to access their electronic health records.

The identification scheme is a combination of previous work by Jin using a person’s unique brainprint instead of traditional passwords for access to computers and buildings combined with cyber-security work from Guo and Chen.

“This research will be very helpful and significant for next-generation secure, personalized healthcare,” said Jin.

Since an ECG may change due to age, illness or injury — or a patient may just want to change how their records are accessed — researchers are currently working out ways to incorporate those variables.

Assistant Professor Linke Guo and Associate Professor Yu Chen, along with PhD candidates Pei Huang and Borui Li, are co-authors of the paper.

The research was presented at The IEEE Global Communications Conference (GLOBECOM 2016) in Washington, D.C., in December 2016.

The work is supported by Binghamton University’s Interdisciplinary Collaboration Grant (ICG) program.

FBI is Investigating Theft of $1.3 Million in Bitcoin from a Massachusetts Man

October 18, 2016

Over two months ago, the world’s third largest Bitcoin Exchange Bitfinex lost around $72 Million worth of Bitcoins in a major hack.

Shortly after the company encountered a $72,000,000 Bitcoin theft, an unnamed Bitfinex user from Cambridge, Massachusetts, filed a police report in September, alleging that $1.3 Million of funds were stolen from his account.
Since then the Cambridge police have handed the case over to the FBI, which is working with the Bitcoin exchange as well as European authorities to recover funds stolen from the Bitfinex user, Coindesk reports.

The individual claimed that he held $3.4 Million in Bitcoin in his personal wallet hosted by the Bitfinex Bitcoin exchange. But following the August’s Bitfinex breach, he was left with $2.1 Million in his account.

Bitfinex then notified the individual of his initial loss of approximately $1.3 Million in Bitcoin, but after the company issued IOU tokens as an emergency measure to keep the exchange operating, the loss incurred was reduced to just $720,000.
The IOUs or BFX tokens are a form of compensation provided to the victims to reduce their losses by a significant factor.
Although specific details remain still unclear, the Bitfinex user confirmed lose of funds beyond Bitfinex IOU tokens issued to all the victims of the breach.
The usability of the token is still unclear. Neither the explanation of tokens provided by Bitfinex is much clear, nor the legal status of the tokens is known.
“The BFX tokens will remain outstanding until repaid in full by Bitfinex or exchanged for shares of iFinex Inc,” explains the company. “The specific conditions associated with the exchange of these tokens will be explained in a later announcement.”

For the incident report filed by the Bitfinex user, you can head on to this link. No further details about the case are available at this moment.
Shortly after the breach of around $72 Million worth of its customers’ Bitcoins, Hong Kong-based Bitcoin exchange announced a reward of $3.5 Million to anyone who can provide information that leads to the recovery of the stolen Bitcoins.
The incident was so big that the price of Bitcoin was dropped almost 20%, from $602.78 to $541 per Bitcoin, within a day after the announcement.
