Deepfakes

The Epitome of “Fake News”

Deepfakes are the epitome of “fake news”. They are the result of altering video and/or audio to portray something different than was intended in the original version… or creates a complete “fairy tale” version of events that are unrelated, in any way, to the original.

It brings “taking things out of context” to a completely new level. Instead of taking things out of context, it takes them out of the stratosphere!

Fake News Strikes Again!

Why are they a problem?

Deepfakes can easily sway public opinion. We tend to believe what we see. One of the uses of Deepfakes is within political campaigns. Deepfakes can be used to portray a candidate in a negative light when the original footage and/or intent could have been completely innocent.

Deepfakes can also be used by the news media to substantiate a completely false narrative by creating fake footage that illustrates purported visual “evidence”.

One of the techniques used is to swap out the head of one person, with another, and sew the two images together, thus making it look as though a person could be guilty of an act of which they are completely innocent. Originally, such footage might have exhibited a slight “jitter” and/or something about the image would seem to be “off” to the viewer, but technology has quickly advanced making it much more difficult to determine the counterfeit images with only the naked eye.

What can we do about it?

The IT industry has begun to create artificial intelligence (AI) that can spot suspected Deepfake media and alert the monitor.

Companies such as Google are actively training their versions of Deepfake-detecting AI to recognize such trickery, although others warn that the processes used to create Deepfakes are becoming much more sophisticated, and advancing almost by the day.

Lawmakers are determining the structure of bills to counter the increasing use of Deepfakes. Texas is one step ahead and has already put political campaign Deepfake laws into effect.

Update

Since writing this blog, deepfakes have immensely improved their level of sophistication, to the point of the naked eye not being able to tell the difference between a fake and the real thing!

A Digital Shield for Your Online Adventures As tech professionals, we often spend a good chunk of our lives navigating the digital realm. Whether you’re troubleshooting a network, coding a new app, or just binge-watching the latest series, one thing is clear: your connection to the internet is a double-edged sword. It’s both incredibly convenient and, if not properly secured, a potential vulnerability. Enter the VPN (Virtual Private Network) our trusty, digital bodyguard. If you’re not already using one, or if you’re not entirely sure why you should, let’s walk through some of the reasons why a VPN is essential for anyone working in IT and, frankly, for anyone who uses the internet. What Is a VPN? In simple terms, a VPN creates a secure, encrypted tunnel between your device and the internet. It allows your data to travel securely, masking your IP address, and ensuring that no one (be it hackers or nosy advertisers) can track or intercept your online activity. Think of it as your personal “cloak of invisibility” in the digital world!

Futureproofing Our Security In our increasingly connected world, the security of digital information has never been more critical. From banking transactions to private communications, our data is constantly transmitted and stored across the internet. The current systems that protect this data rely on cryptography, a branch of mathematics that helps keep information secure by encoding it in ways that are difficult to decode without the proper key. However, with the rise of quantum computers, traditional cryptography is facing new and significant threats. This is where Post-Quantum Cryptography comes into play. What is Post-Quantum Cryptography? Post-Quantum Cryptography (PQC) [1] refers to cryptographic algorithms that are specifically designed to be secure against the power of quantum computers. Quantum computers, once they become practical, will be capable of solving complex mathematical problems much faster than classical computers. This will render many of the encryption methods we rely on today [such as RSA (Rivest, Shamir, and Adleman – initials of the inventors) and ECC (Elliptic Curve Cryptography)] vulnerable to attack. Quantum computers operate on quantum bits, or “qubits”, which can exist in multiple states simultaneously, unlike classical bits that are either a zer (0) or one (1). This allows quantum computers to perform certain calculations exponentially faster than classical computers. For example, in a matter of seconds, a quantum computer could potentially break an RSA key, which is considered secure by today’s standards. As quantum computing technology advances, the need for PQC becomes even more urgent.
