Machine learning on blockchain: A new approach to engineering computational security
2025-02-28
(Press-News.org)
A new study published in Engineering presents a novel framework that combines machine learning (ML) and blockchain technology (BT) to enhance computational security in engineering. The framework, named Machine Learning on Blockchain (MLOB), aims to address the limitations of existing ML-BT integration solutions that primarily focus on data security while overlooking computational security.
ML has been widely used in engineering to solve complex problems, offering high accuracy and efficiency. However, it faces security threats such as data tampering and logic corruption. BT, with its features of decentralization, transparency, and immutability, has been explored to safeguard engineering data. But the traditional ML process remains vulnerable to off-chain risks as ML models are often executed outside the blockchain.
The MLOB framework places both data and the computational process on the blockchain, executing them as smart contracts and protecting execution records. It consists of four core components: ML acquisition, where an ML model is trained for a specific task; ML conversion, which adapts the trained model for blockchain deployment; ML safe loading, ensuring the security of data and model transfer; and consensus-based ML model execution, guaranteeing the safety and correctness of computations.
To illustrate the effectiveness of the MLOB framework, the researchers developed a prototype and applied it to an indoor construction progress monitoring task. They compared the MLOB framework with three baselines and two recent ML-BT integrated approaches. The results showed that the MLOB framework significantly enhanced security, successfully defending against six designed attack scenarios. It maintained a high level of accuracy, with only a 0.001 difference in the mean intersection over union (MIoU) metric compared to the best baseline method. Although it had a slightly compromised efficiency, with a 0.231 second latency increase compared to the most efficient baseline, the overall performance met the requirements of industrial practice.
The MLOB framework also has managerial implications. It encourages organizations to innovate by integrating advanced technologies, which can lead to more competitive engineering operations. It also helps mitigate risks associated with data and logic security, optimizing resource allocation and enhancing economic resilience.
However, the framework has some limitations. It has limited support for latency-sensitive scenarios and lacks a user-friendly interface. Future research will focus on optimizing its efficiency and designing a more accessible user interface to further improve its usability and expand its application in engineering computing.

A new review article published in Engineering offers a comprehensive look at vacuum glazing, a technology that shows great potential in enhancing energy efficiency in buildings. As buildings account for around 40% of society’s total energy consumption, improving the thermal performance of glazing is crucial for achieving low-carbon building goals.
Vacuum glazing has gained attention for its heat preservation, sound insulation, lightweight features, and anti-condensation properties. The concept dates back to 1913, but it was not until 1989 that researchers in Australia successfully produced vacuum glazing with excellent thermal insulation performance. Since then, significant ...

About The Study: In this study, differences in out-of-pocket maternity spending among the commercially insured were associated with differences in coinsurance rates. These costs could lead people to forgo needed health care or other basic needs that support health (e.g., food or housing). Changes to health plan benefit design could improve equity in out-of-pocket maternity spending and its consequences.

COLLEGE PARK, MD – A new study out today in JAMA Health Forum is the first to show that Black, Hispanic and Asian people with private insurance tend to pay more out-of-pocket for maternity care than white people.
“The average additional spending on medical care from pregnancy through postpartum paid by people who are Black, Hispanic and Asian is significantly more than white people,” said Dr. Rebecca Gourevitch, the study’s lead author and an assistant professor in the Department of Health Policy and Management at the University of Maryland School of Public Health (UMD SPH).
“We found that out-of-pocket costs were highest ...

About The Study: During the COVID-19 pandemic, food insecurity decreased among Supplemental Nutrition Assistance Program (SNAP) participants in most racial and ethnic groups but did not decrease among non-SNAP participants in any group. These results suggest that during the pandemic, increased SNAP benefit amounts were associated with ameliorating food insecurity for many U.S. adults who were able to access SNAP but did not reduce racial and ethnic disparities in food insecurity.

On February 7, 2025, the U.S. National Institutes of Health announced a decision to cap indirect cost reimbursement—which supports the critical infrastructure and staff that make biomedical research possible—at 15%. In a commentary published February 28 in the Cell Press journal Cell, molecular biologist Tom Maniatis of the New York Genome Center (NYGC) and Columbia University's Zuckerman Institute reflects on the impact NIH funding has had on his own career and science, explores the value indirect investment has brought to U.S. science over the last five decades, and calls for urgent, unified action from the scientific community ...

Despite ongoing progress, structural racism and health disparities continue to shape healthcare practices in ways healthcare providers may not even realize. A recent study in JAMA Network Open, published Feb. 28, 2025, shows that continued use of race-specific equations in the diagnostic process of children with asthma symptoms limits the identification of reduced lung function in Black children.
“This finding is important because when these children are not identified as having reduced lung function, they may not receive further testing. This can lead to under-diagnosis, ...

Hepatic steatosis, often triggered by non-alcoholic fatty liver disease (NAFLD), is a leading cause of liver dysfunction globally, affecting approximately 30% of the population. The progression from steatosis to hepatic fibrosis, which may ultimately lead to cirrhosis, is a significant concern in liver disease management. This review highlights the critical role of solute carrier (SLC) family transporters in both hepatic steatosis and fibrosis. SLC transporters are membrane-bound proteins responsible for transporting a variety of molecules, including fatty acids, ...

Scientists have a new target to prevent cold sores after University of Virginia School of Medicine researchers discovered an unexpected way the herpes virus re-activates in the body. The finding could also have important implications for genital herpes caused by the same virus.
The discovery from UVA’s Anna Cliffe, PhD, and colleagues seems to defy common sense. She and her team found that the slumbering herpes virus will make a protein to trigger the body’s immune response as part of its escape from dormancy. You’d think this would be bad for the virus – that activating the body’s ...

Glenview, Illinois – The American College of Chest Physicians (CHEST), the PF Warriors, the Rare Disease Diversity Coalition (RDDC)—a program at the Black Woman's Health Imperative—and the National Association of Community Health Workers (NACHW) announce their collaboration to address idiopathic pulmonary fibrosis (IPF) as a chronic disease on Rare Disease Day 2025.
Together, the organizations will employ designated activities that will build a knowledge base on the current IPF landscape ...

The study, which examined 121 babies aged three to twelve months in Accra, the capital of Ghana, demonstrates a remarkable variety of language input in the early months of life. The children are regularly exposed to two to six languages. Strikingly, the number of caregivers the children have also ranges between two and six, and babies who have more adults in their daily lives who regularly take care of them also hear more different languages. In Ghana, families often live in so-called “compound buildings”, where many ...
