Home security cams hacked in Singapore, and stolen footage sold on adult websites

Posted by in categories: food, habitats, internet, security

* Unsecured home security cameras hijacked * Stolen images circulate on Discord * Everyone needs to take IoT security more seriously.

In Singapore it’s not at all uncommon today for people to have IP cameras all over their homes.

And, of course, the more people who installed internet-connected cameras throughout their private residences the more you would be considered odd if you hadn’t jumped on the bandwagon, and put cameras in your living room, kitchen, bedroom, sometimes even with a view of even more private areas of your house.

Challenges for LEO HTS Megaconstelllations: Terrestrial Networks Integration

Posted by in categories: government, internet, satellites

Satellite communication has been serving the terrestrial network as a complementor rather than a competitor for a considerable time. The best use-case scenario is the cellular backhaul over VSAT (Very Small Aperture Terminal) to connect remotely installed BTS (Base Transceiver Station) of a cellular network through a geostationary satellite to the respective BSC (Base Station Controller) and ultimately the core network. This technology enabled MNOs (Mobile Network Operators) to increase their subscribers base in remote communities which could not be connected to their network grid through Microwave or Fibre transmission. Similar network architecture, commonly known as bent-pipe and FSS (Fixed Satellite Service), has been used by other networks requirements of ISP (Internet Service Providers), Government, Corporate, Oil & Gas, Mining sectors, where the DCE (Data Communication Equipment) and DTE (Data Terminal Equipment) are replaced from BTS and BSC to networking switches and routers.

However, all these communications are struggling to keep at par with development at terrestrial networks, and the main reason is staggering latency of around 530 milliseconds for a roundtrip of a message through the satellites at an altitude of around 37,000 kilometres, which is a big challenge for Industry 4.0 technologies. The arrival of the planned NGSO mega constellation appears to address the problem through claimed significantly lower latency of around 4 milliseconds, which is at par with fibre optics.

The integration of the networks of mega constellations with those on the ground is a complicated situation with multiple dynamics to analyse. Let us have a brief look at 4G LTE and 5G NR technology and analyse the integration for both backhaul and fronthaul interfaces through NGSO satellites with the core networks.

Elon Musk’s Starlink Space Internet Is Ready For Public Use

Posted by in categories: Elon Musk, internet, satellites

Elon Musk, the CEO of SpaceX, has announced that his space internet project is ready for public use. The statement comes after SpaceX launched 60 Starlink satellites into low-Earth orbit last week, bringing the total number to almost 800.

Eventually, SpaceX plans to launch tens of thousands of Starlink satellites to create a blanket around the Earth capable of beaming high-speed broadband internet to 99% of the inhabited world.

The Coming Internet: Secure, Decentralized and Immersive

Posted by in categories: computing, disruptive technology, electronics, information science, internet, open access, supercomputing

The blockchain revolution, online gaming and virtual reality are powerful new technologies that promise to change our online experience. After summarizing advances in these hot technologies, we use the collective intelligence of our TechCast Experts to forecast the coming Internet that is likely to emerge from their application.

Here’s what learned:

Security May Arrive About 2027 We found a sharp division of opinion, with roughly half of our experts thinking there is little or no chance that the Internet would become secure — and the other half thinks there is about a 60% probability that blockchain and quantum cryptography will solve the problem at about 2027. After noting the success of Gilder’s previous forecasts, we tend to accept those who agree with Gilder.

Decentralization Likely About 2028–2030 We find some consensus around a 60% Probability and Most Likely Year About 2028–2030. The critical technologies are thought to focus on blockchain, but quantum, AI, biometrics and the Internet of things (IoT) also thought to offer localizing capabilities.

The Most Sensitive Optical Receivers Yet for for Laser-Beam Based Space Communications

Posted by in categories: internet, space

Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications, using an almost noiseless optical preamplifier in the receiver, was recently demonstrated by researchers at Chalmers University of Technology, Sweden.

In a new paper published in the scientific journal Nature: Light Science & Applications, a team of researchers describes a free-space optical transmission system relying on an optical amplifier that, in principle, does not add any excess noise — in contrast to all other preexisting optical amplifiers, referred to as phase-sensitive amplifiers (PSAs).

The researchers’ new concept demonstrates an unprecedented receiver sensitivity of just one photon-per-information bit at a data rate of 10 gigabits per second.

Elon Musk Is Providing Internet To Wildfire Towns To Help Firefighters

Posted by in categories: Elon Musk, internet, satellites

Elon Musk’s company SpaceX has given emergency responders in Washington access to its Starlink satellites to help fight fires.

Through the satellite-based internet constellation Starlink, SpaceX plans to provide broadband internet across the globe and enable connectivity to billions of people who may not have reliable internet access.

SpaceX has already launched hundreds of satellites into orbit, though the firefighters’ use of the network is the first early application of the internet service to be disclosed.

Space internet is ready for people to start using it, Elon Musk says

Posted by in categories: Elon Musk, internet, satellites

The private space firm hopes to eventually launch tens of thousands of Starlink satellites to create a constellation capable of beaming high-speed broadband down to 99 per cent of the inhabited world.

“Once these satellites reach their target position, we will be able to roll out a fairly wide public beta in northern US and hopefully southern Canada,” Musk tweeted following the launch.

“Other countries to follow as soon as we receive regulatory approval.”
