What is Video Encryption?
Video Encryption is the process of safeguarding accessibility to different videos against unauthorized users by encoding them.
Video encryption techniques are mainly used to prevent unauthorized users from viewing or downloading different digital assets on the internet.
How Does Video Encryption Work?
Video files, upon creation, are encrypted so that they can only be read by users with access to the encryption key.
Without such a key, the video file will just seem like a series of gibberish and illegible letter sequences that cannot be read by any hardware or software. People cannot view or download video files without the encryption key.
In most cases, video encryption takes place with the help of encoding software and hardware.
Major Types of Video Encryption
- AES 128 Encryption: It is the most commonly used and basic encryption technology. Most developers and creators use it to encrypt their videos and protect their raw videos against visibility within the network.
- HLS Encryption with AES-128: HLS Encryption streams videos with the help of HLS protocol. Video encryption, on the other hand, takes place with the help of the AES-128 algorithm.
- Real-Time Messaging Protocol (RTMP) and RTMP Encrypted (RTMPE): RTMP was originally developed to support only live streaming. But today, it is also used by many developers to stream and broadcast their audio-video content in software like Flash players, mobile applications, and desktops.
The Working of AES Encryption
The AES Encryption technology works based on three different “secret keys” with different lengths of cryptography.
The cryptograph is responsible for facilitating the encryption and all the process related to encryption. The length of the cryptograph determines the strength of the protection offered.
The three lengths the secret key uses are 128-bit, 192-bit, and 256-bit.
In the AES Encryption process, one of the keys is taken with some data, making it unreadable after scrambling. Thus, the file becomes unrecognizable unless the viewer has the appropriate decoder or encryption key.
Key Benefits of Video Encryption
- It safeguards video assets from unauthorized access while ensuring their quality and mobility.
- It helps businesses comply with industry standards for protecting their digital assets, thus preventing lawsuits and legal issues.
- It prevents any violations of privacy during subscriber-platform exchanges.
- It provides authorized users with seamless access through automated methodologies, ensuring that broadcasters don't have to worry about any authorized user being unable to access their digital content.
