We have developed a new way to protect video transmissions. This will prevent even future quantum computers from entering live streams or recordings of private video. We are computer scientists who study computer security. In our study, we present Quantum-Safe video encryption. It combines two complementary techniques: Quantum Encryption and Secure Internet Transmission.
With encryption systems, hackers cannot access or understand video data. An encryption key scrambles data so that only those with the correct key cannot scramble it. If a hacker even tries to peak, the system will detect it and raise the alarm. This video can also be moved digitally, the equivalent of a locked box on the Internet, so it cannot be replaced or tampered with during transportation.
Quantum cryptography uses true random encryption keys based on quantum physics to scramble video data. Unlike traditional encryption, which relies on mathematical complexity, quantum encryption uses the fundamental unpredictability of quantum states to generate unbroken keys.
Quantum refers to the scale of atoms and molecules that operate in counterintuitive ways. Quantum computers take advantage of these strange behaviors to solve problems that are difficult or impossible for a normal computer.
This quantum cryptography scheme combines secure transmission over the Internet using transport layer security. This is an encryption scheme used to keep the connection between a web browser and a web page private.
Our approach works by converting each video frame into a quantum image representation. This is essentially a mathematical framework that captures visual information in quantum states. The data is then scrambled in combination with quantum-generated random keys, making it impossible to distinguish the encrypted video purely.

Additionally, quantum cryptography is resistant to future technologies such as quantum computers, so this video will remain safe for years to come.
Why is it important?
Until tomorrow's quantum computer arrives, today's encryption will work well. These super-strong machines can break most current encryption methods in seconds. This means that today's private videos stored on cloud platforms or sent over the internet could be decrypted in a few years.
Even more dangerous, these stolen videos can be manipulated deepfake. Forged videos can ruin reputation, shake up decisions and even cause violence. A secure encryption system not only protects privacy, but also helps protect the truth.
What else is being done?
Researchers around the world are exploring quantum key distributions to securely share encryption keys. Others use chaos theory, deep learning, or hybrid algorithms to protect the content of your videos and images.
However, most existing work focuses solely on images, or key exchanges, without fully protecting live or saved video data.
What's next?
This system is scaled to encrypt complete video files and real-time video streams, such as those used in video conferencing and surveillance systems.
The next steps include reducing performance overhead for smooth playback and testing the system in a real environment. They are also exploring ways to work with Deepfake Detection Tools, which not only stops hackers from accessing the video, but also proves that the video has not been changed.
Although our framework shows strong early results, as quantum systems become more accessible over the years, practical use relies on staged adoption.
The research summary is a short view of interesting academic work.
