The Top Security Challenges Data Centers Face in 2022
Data centers and providers employ some of the most sophisticated cybersecurity measures available to protect systems, hardware, and customer information. However, that does not mean
It’s Time to Bake Security into Software from the Start
One of the most unexpected consequences of ransomware attacks in 2021 may have been the nationwide cream cheese shortage caused by an attack on one
IoT Health Data in Electronic Health Records (EHR): Security and Privacy Issues in Era of 6G
Millions of wearable devices with embedded sensors (e.g., fitness trackers) are present in daily lives of its users, with the number growing continuously, especially with the approaching 6G communication technology. These devices are helping their users in monitoring daily activities and promoting positive health habits. Potential integration of such collected data into central medical system would lead to more personalized healthcare and an improved patient-physician experience. However, this process is met with several challenges, as medical data is of a highly sensitive nature. This paper focuses on the security and privacy issues for such a process. After providing a comprehensive list of security and privacy threats relevant to data collection and its handling within a Central Health Information system, the paper addresses the challenges of designing a secure system and offers recommendations, solutions and guidelines for identified pre-6G and 6G security and privacy issues.
The Cybersecurity Risks of Cryptocurrency
The evolution of cryptocurrency has taken the world by storm in the past decade. In 2013, there were only 66 types of cryptocurrency worldwide. In February 2022, Statista reports around 10,397 cryptocurrencies that people can invest in.
Cryptocurrency, often referred to as just crypto, is a form of digital money. This electronic currency uses blockchain technology, a secure, digital ledger containing crypto transactions.
While many investors are keen on learning about crypto, following the latest crypto trends and making a profit, it’s critical to weigh the risks associated with trading cryptocurrency.
Below, we’re going to discuss some of the cybersecurity risks associated with investing in crypto, as well as some ways to protect yourself when investing your hard-earned money into digital tokens.
Adaptive Matrix Pattern Steganography on RGB Images
Abstract: Almost all spatial domain image steganography methods rely on modifying the Least Significant Bits (LSB) of each pixel to minimize the visual distortions. However, these methods are susceptible to LSB blind attacks and quantitative steganalyses.
This paper presents an adaptive spatial domain image steganography algorithm for hiding digital media based on matrix patterns, named “Adaptive Matrix Pattern” (AMP). The AMP method increases the security of the steganography scheme of largely hidden messages since it adaptively generates a unique codebook matrix pattern for each ASCII character in each image block.
