Enhancing Your Safety on Public Wi-Fi: The Power of a VPN
“Protect your data on public Wi-Fi with a VPN. Encrypt, mask your IP, and secure your connection. Stay safe with ExpressVPN or Surfshark.”
Last Updated on June 25, 2024 by Daily News Staff
Public Wi-Fi has become an essential service available in coffee shops, bars, trains, and planes worldwide. However, it’s important to note that many of these networks are completely unsecured, leaving room for hackers to intercept your data, monitor your online activities, and potentially steal your private information. If you frequently connect to these hotspots, taking the time to learn about VPNs and their benefits can prove invaluable. This article aims to guide you in staying safe on public Wi-Fi.
Understanding the Risks of Public Wi-Fi
The greatest risk of connecting to public Wi-Fi lies in the possibility of falling victim to man-in-the-middle attacks. These attacks occur when an attacker intercepts the communication between your device and the Wi-Fi network, potentially gaining access to sensitive data such as your online banking details, passwords, and personal information.
Furthermore, public Wi-Fi networks can serve as breeding grounds for rogue networks. These malicious networks mimic legitimate ones and are set up by attackers to deceive unsuspecting users. Connecting to rogue networks unknowingly exposes your data to cybercriminals.
How Can a VPN Safeguard You on Public Wi-Fi?
A VPN (Virtual Private Network) shields you from these threats by routing your internet traffic through its own secure servers using powerful encryption. Here’s how it works:
- • Encryption: A VPN encrypts your data, rendering it unreadable to potential interceptors. Utilizing industry-standard AES-128 or 256 encryption, VPNs ensure that your data remains virtually uncrackable.
- • Anonymity: By masking your IP address, a VPN makes it harder for others to trace your online activities back to you.
- • Secure Connection: When you connect to a VPN server, your data travels through a secure tunnel, preventing hackers from accessing your information even if the public Wi-Fi network is compromised.
Choosing the Right VPN for Public Wi-Fi
When selecting a VPN for public Wi-Fi, consider your online activities and the duration of your usage. Here are some factors to keep in mind:
- • Data Limits and Speeds: Free VPNs often impose data limits and throttle speeds, which may suffice for occasional use but prove inadequate for regular or extended sessions.
- • Device Compatibility: Ensure that the VPN has apps available for all your devices. Premium VPNs generally support a range of platforms, including smartphones, tablets, and laptops.
- • Streaming Capability: If you want to watch videos during your breaks, opt for a VPN that can access popular streaming sites.
- • Reliability and Support: Look for VPN providers that offer 24/7 support and have a solid reputation for reliability.
Our top-rated VPN is ExpressVPN, renowned for its military-grade encryption, fast connection speeds, and exceptional customer support. With its versatility and compatibility across virtually all devices, ExpressVPN offers a 30-day money-back guarantee, allowing you to test it risk-free.
For those on a budget, Surfshark makes an excellent alternative. It provides robust security features at a lower cost, making it an ideal choice for regular public Wi-Fi users seeking reliable protection without breaking the bank.
While public Wi-Fi offers convenience, it also carries substantial risks. Using a VPN is a simple yet effective method to safeguard your data from prying eyes. Whether you choose a premium service like ExpressVPN or a budget-friendly option such as Surfshark, investing in a reliable VPN is a small price to pay for the peace of mind it brings.
By taking this precaution, you can safely browse, work, and enjoy your online activities on public Wi-Fi networks without worrying about cyber threats. Stay informed, stay secure, and make the most of the digital world with the protection of a VPN. Remember that your safety matters, and a VPN can be your strongest ally in the world of public Wi-Fi.
A virtual private network (VPN) is a mechanism for creating a secure connection between a computing device and a computer network, or between two networks, using an insecure communication medium such as the public Internet.[1]
A VPN can extend access to a private network (one that disallows or restricts public access) to users who do not have direct access to it, such as an office network allowing secure access from off-site over the Internet.[2]
The benefits of a VPN include security, reduced costs for dedicated communication lines, and greater flexibility for remote workers.[3]
A VPN is created by establishing a virtual point-to-point connection through the use of tunneling protocols over existing networks. This process involves encapsulating and encrypting the data to ensure secure transmission between two or more devices. A VPN available from the public Internet can provide some of the benefits of a private wide area network (WAN). These benefits include enhanced security, privacy, and the ability to bypass geographical restrictions, making it an essential tool for both individuals and businesses seeking to protect sensitive information and access restricted content while maintaining anonymity online. https://en.wikipedia.org/wiki/Virtual_private_network

Drones paired with AI could help search‑and‑rescue teams find missing persons faster
AI-powered drones equipped with thermal and infrared imaging are transforming search-and-rescue operations, enabling teams to locate missing persons faster and assess their condition—including signs of injury, consciousness, or life-threatening temperature changes—in real time.

A combination of infrared imaging, thermal imaging and color cameras on an uncrewed drone, along with an AI system to interpret the data, can help emergency responders and search-and-rescue teams locate, identify and track people who have gone missing in the wilderness. The experimental system helps responders pinpoint where a missing person is and determine whether they are hurt or even alive.
People who get lost or hurt while exploring nature can become stranded for days. Rescue teams often use drones to look for the person or signs of their whereabouts. The small drone my colleagues and I built at my lab at Kennesaw State University flies autonomously using a grid search pattern. It sends live video and images to a ground station operated by the rescue team.
When the AI system finds a person, it analyzes images to determine whether the individual is upright or lying on the ground. It segments parts of the person’s body, identifying the person’s head and the body’s position. It then zeroes in on the forehead. It extracts forehead temperature readings, pixel by pixel, from the imaging data to estimate forehead temperature. We have two papers detailing these findings accepted for the American Institute of Aeronautics and Astronautics Aviation Forum 2026 conference.
Our AI model then assesses whether the person is conscious or unconscious and identifies abnormal temperatures that could indicate heat stress, hypothermia or other physical complications, or death – all vital information for a search-and-rescue team.
In field trials we have conducted, the system has provided consistent temperature readings of the heads of volunteers from our research team who have walked out into a variety of environments, under different conditions.
Why it matters
It is critical to get accurate and timely information on the whereabouts of a missing person. The likelihood that the person will survive decreases steeply as time passes.
An AI-enhanced drone can make search-and-rescue operations significantly more efficient than sending teams of people out into the environment to search on foot, especially in poor weather conditions or under thick foliage. Rescuers who know whether a person is conscious or unconscious can also better gear up for what they need to do to retrieve the person and administer aid. Our technology could save lives.
What other research is being done
Search-and-rescue personnel use various kinds of drones, but the machines often lack the ability to positively identify humans, especially under thick foliage, in bad weather or when the person is lying down or unconscious. The AI-based technology we have developed overcomes those challenges.
Better sensors that are very lightweight, that can function at night or in rain, and can see more clearly through thick foliage could further improve our drone and drones used by others. Researchers are devising AI-powered sound recognition for detecting screams for help, advanced thermal imaging for better nighttime vision and autonomous drones that could act as first responders.
Also under development are drones that can carry heavy payloads, such as flotation devices, fly for up to 14 hours or perform real-time mapping of the ground below.
What’s next
One of our next steps is to have multiple drones fly together and autonomously coordinate search-and-rescue operations among themselves. This will allow the technology to cover a much larger area, perhaps hundreds of square miles.
We are also designing a large drone that can carry up to 110 pounds (50 kilograms) of payload and stay aloft for an hour.
The Research Brief is a short take on interesting academic work.

Stay Protected from Cyberattacks: Simple Safeguards to Reduce Cyber Intrusions and Real-World Losses
(Feature Impact) Connected homes are becoming the norm with millions of Americans relying on Wi-Fi networks, mobile apps and smart devices to manage everything from door locks to thermostats.
As convenience increases, so does exposure, and the experts at multiple-line insurance carrier Mercury Insurance are reminding homeowners that basic cybersecurity practices can help reduce both their digital and physical risks.
“Smart-home technology is incredibly useful, but it also expands the number of entry points into your home – not just digitally, but physically,” said Dustin Howard, head of info security at Mercury Insurance. “The good news is that many of the most effective protections are simple, proactive steps that homeowners can take today.”
Smart-home adoption continues to accelerate with recent studies showing roughly 70% of U.S. households now use at least one connected device. From video doorbells to smart garage doors, these tools provide visibility and control, but if not properly secured, they can also create vulnerabilities that bad actors may exploit.
Consider these cybersecurity best practices for connected homes:
- Secure your Wi-Fi network: Use strong, unique passwords – at least 14-16 characters with a mixture of letters, numbers and symbols – and enable WPA3 encryption when available to prevent unauthorized access. Also turn on your router’s built-in firewall and disable Wi-Fi protected setup.
- Update devices regularly: Firmware and software updates often include critical security patches that close known vulnerabilities. Turn on automatic updates for operating systems, applications, browsers and smart home devices such as thermostats and cameras. If devices are no longer able to update, it may be time to replace them to avoid compromising security.
- Enable multi-factor authentication (MFA): Adding a second layer of verification significantly reduces the risk of unauthorized account access. Enable MFA for email accounts, banking and financial apps, cloud storage and social media accounts, and use an authenticator app for confirmation rather than receiving a code via text or email.
- Segment your network: Consider placing smart-home devices, including televisions, security cameras and speakers, on a separate network from personal devices like laptops and phones. Also create a guest network for visitors to use to help further protect your main network.
- Change default settings: Many devices come with default usernames and passwords that are widely known and easily exploited. Change the defaults on your router as well as login credentials for any new devices, making admin accounts more difficult to target.
- Monitor device activity: Regularly review connected devices and remove any that are unfamiliar or no longer in use. If your router supports it, enable notifications for new device connections for real-time visibility.
“As homes become more connected, cybersecurity becomes a core part of overall home protection,” Howard said. “It’s not just about protecting your data – it’s about protecting your property, your privacy and your peace of mind.”
With smart-home technology expected to continue expanding, homeowners should treat cybersecurity as a routine part of home maintenance – just like checking smoke detectors or locking doors – to stay ahead of evolving risks.

Artemis II crew brought a human eye and storytelling vision to the photos they took on their mission
Artemis II crew: Artemis II’s astronaut photos show how human perspective and storytelling make space imagery feel authentic—especially in an era of AI-generated visuals.
Christye Sisson, Rochester Institute of Technology
In early April 2026, the Artemis II mission captivated me and millions of people watching from across the world. The crew’s courage, skill and infectious wonder served as tangible proof of human persistence and technological achievement, all against the mysterious backdrop of space.
People back on Earth got to witness the mission through remarkable photos of space captured by astronauts. Images created and shared by astronauts underscore how photography builds a powerful, authentic connection that goes beyond what technology alone can capture.
As a photographer and the director of the Rochester Institute of Technology’s School of Photographic Arts and Sciences, I am especially drawn to how these photographs have been at the center of the public’s collective experience of this mission.
In an era when image authenticity is often questioned and with the capabilities of autonomous, AI-driven imaging, NASA’s choice to train astronauts in photography has placed meaning over convenience and prioritized their human perspectives and creativity.
Capturing space from the crew’s perspective
Photography was not originally placed as a high priority in NASA’s Apollo era. The astronauts only took photographs if they had the chance and all their other tasks were complete.
Thanks largely in part to public response to those images from Apollo, including “Earthrise” and the “Blue Marble” being widely credited for helping catalyze the modern environmental movement, NASA shifted its approach to utilize photography to help capture the public’s imagination by training their astronauts in photographic practices.
The Artemis II mission’s photographs have helped cut through the increasing volume of artificially generated images circulating on social media. NASA’s social media releases of the crew’s photographs have garnered thousands of shares and comments.
This excitement could be explained by the novelty of photos from space, but these images also distinguish themselves as products of astronauts experiencing these sights and interpreting them through their photographs. These differences require an important distinction around where technology ends and humanity begins.
Human perspective versus AI tools
Photography has long integrated AI-powered software and data-driven tools in a variety of ways: to process raw images, fill in missing color information, drive precise focus and guide image editing, among others. These modern technological assists help human photographers realize their vision.
Artificial intelligence is also increasingly capable of operating machinery competently and autonomously, from cars to drones and cameras.
And AI can generate convincing, realistic images and videos from nothing more than a text prompt, using readily available tools.
Researchers train AI to mimic patterns informed by millions of sample images, and the algorithm can then either take or create a photograph based on what it predicts would be the most likely version of a successful, believable image.
Human-created photos are rooted in direct observation, intent and lived experience, while AI images – or choices made by AI-driven tools – are not. While both can produce compelling and believable visuals, the human photographs carry emotional power because the photographer is drawing from their experiences and perspective in that moment to tell an authentic story.
Artemis II photographs resonate, not only because they are historic, but because they reflect the deliberate choices and intent of a human being in that specific moment and context. The exposure, camera setting, lens choice and composition are all dictated by the astronaut’s vision, skill, perspective and experience. Each image is unique in comparison with the others. These choices give the images narrative power, anchoring them in human perspective.
Images to tell a story
Photographers choose what to include in the final version of their image to tell a story. In the Artemis II images, this human perspective comes out. In the “Earthset” photo, you see a striking juxtaposition of the Moon’s monochromatic, textured surface in the foreground against a slivered, bright Earth.
The choice to include both in the frame contrasts these objects literally and figuratively, inviting comparison. It creates a narrative where Earth is contrasted against the Moon – life is contrasted against the absence of it.
Another photo shows the nightside of the whole Earth, featuring the Sun’s halo, auroras and city lights. The choice to include the subtle framing of the window of the capsule in the lower left corner reminds the viewer where and how this image was captured: by a human, inside a capsule, hurtling through space. That detail grounds the photograph in the human perspective.
Both photos are reminiscent of Earthrise and the Blue Marble. These past images hold a place in the global collective consciousness, shaped by a shared historical moment.
The Artemis II photographs are anchored in this collective moment of lived human experience, yet also shaped by each astronaut’s viewpoint. The crew’s unique perspectives exemplify photography’s transformative power by inviting viewers to engage emotionally and intellectually with their journey. These photographs share the astronauts’ awe and wonder and affirm the value of human creativity and its ability to connect us in a captured moment.
