What is Video Encryption?

Video encryption is a security process protecting video content from unauthorized access. It converts original video data into an unreadable format. Thus it secures content from theft and piracy. Video encryption relies on an encryption key. The authorized users only know this code and can access encrypted content. Unauthorized users cannot view or decode the video data without the key. Various encryption techniques exist. AES encryption is well-known and widely used. AES stands for Advanced Encryption Standard. It’s a strong method of ensuring content safety from illicit use.

When encrypting a video, the original file transforms. It becomes a scrambled format, incomprehensible without the encryption key. This key decrypts and grants access to the content. Users can easily share and store encrypted videos across platforms. There are no unauthorized access risks. Only viewers with the correct key can unlock the content. Thus, it maintains control and protects the owner’s intellectual property rights.

How does Video Encryption Work?

How Video Encryption Works

Create an Encrypted Video Stream

Video encryption begins with the encryption software processing the original video file. The software divides the video into smaller segments to achieve encrypted video streaming. Each segment is then encrypted using a specific encryption method. Advanced Encryption Standard (AES) is the most popular of them.

AES Video Encryption Process

AES video encryption is an industry-standard method utilized for its strong security features. It uses a symmetric key algorithm. That means it uses the same key for encryption and decryption. The most available AES encryptions are:

  • AES-128
  • AES-192
  • AES-256

The higher key lengths offer stronger security.

In AES video encryption, the encryption key scrambles the video segments. This process makes the segments unreadable without the decryption key. The encrypted segments are combined. They create a single encrypted video file ready for streaming.

Protected Delivery of Encrypted Video

When a user requests video streaming, the streaming server delivers the encrypted video. The server allows only authorized viewers by checking user credentials. The viewer is granted access to the decryption key after the successful verification.

Decryption Process

An authorized user’s device receives the encrypted video stream and the decryption key. The device’s video player, built with video encryption software, uses the decryption key. It decrypts the video segments. The player reassembles these segments into the original video format. Then, it plays the video decrypted video to the viewer.

Server-to-Viewer Encryption

Video encryption software secures the transmission of video streams between the server and the viewer’s device. Technologies like Secure Sockets Layer (SSL) or Transport Layer Security (TLS) help achieve this encryption. The server and viewer devices establish a secure connection. It ensures additional protection for encrypted video content.

Digital Rights Management (DRM)

Additional protection is offered by integrating DRM into the video encryption process. DRM stands for Digital Rights Management. It provides a framework for securely distributing digital content. Moreover, it effectively controlled unauthorized access and sharing. DRM systems like Widevine, PlayReady, and FairPlay help video providers maintain secure streaming. They also help to enforce licensing agreements.

User Authentication and Access Control

Video encryption software often features user authentication and access control systems. These systems protect video content by requiring individual users to sign in with unique login credentials. Access controls can be set to grant or restrict user access to specific content based on their given permissions.

Video encryption works through a series of steps involving AES video encryption, secure server-to-viewer communication, user authentication, access control, and DRM integration. By employing these techniques and incorporating video encryption software, content providers can protect and stream their videos securely to authorized users, ensuring the safety of digital assets in today’s online world.

Meeting Legal Requirements

Video encryption is often a requirement to comply with legal regulations and industry standards. Encrypted streaming can help platforms conform to laws such as the General Data Protection Regulation (GDPR) and the Digital Millennium Copyright Act (DMCA), avoiding potential penalties and reputation damage.

Attracting High-Value Content

Securing video files through encryption is crucial for attracting high-value content to a platform. With comprehensive encryption methods, premium content creators are more likely to trust the platform with their content, resulting in more attractive libraries for users.

Gaining Competitive Advantage

As unauthorized streaming and piracy continue to plague the video industry, secure platforms offering encrypted streaming differentiate themselves from potential competitors. These platforms build trust and credibility among content creators and users by showcasing strong security measures, increasing user retention and platform growth.

Types of Video Encryption Technologies

AES 128 Encryption:

AES 128 encryption is a widely used video encryption technology. AES, or Advanced Encryption Standard, provides high video protection. In this method, a 128-bit key is used to encrypt and decrypt videos, balancing security and performance. The same key performs encryption and decryption tasks as a symmetric key algorithm. DRM video encryption also incorporates AES 128 in their systems, making it a popular choice for video streaming platforms.

HLS Encryption with AES-128:

HLS, or HTTP Live Streaming, is a video streaming protocol developed by Apple. HLS encryption with AES-128 combines the security of the AES-128 encryption method with the adaptive streaming capabilities of HLS. This approach enhances video protection while optimizing content delivery to viewers based on their internet connection and device capabilities.

In HLS encryption, the video files are divided into small segments. Each segment is encrypted individually using the same AES-128 encryption key. Encrypting the segments separately prevents unauthorized users from accessing the entire video, even if they manage to decrypt one segment.

Encryption with Real-Time Messaging Protocol (RTMP):

RTMP is a widely used protocol for low-latency video streaming. Developed by Adobe Systems, it delivers high-quality, real-time audio and video content over the Internet. Real-Time Messaging Protocol Encryption (RTMPE) is an encryption technology that adds a layer of security to video streams using the RTMP protocol.

RTMPE uses an obfuscation technique to disguise the content transmitted between the server and the viewer’s device. While less secure than other encryption methods like AES-128, it provides a basic level of video protection for content creators and streaming platforms.

Combining RTMP with HLS and AES 128 encryption can yield even better results. This approach simultaneously delivers the video content in RTMP and HLS formats. The HLS version is encrypted with AES-128, while the low-latency RTMP version is available for real-time interactions. The viewers’ devices can switch between the same video versions based on their preferences and capabilities.

AES-128 vs. AES-256: Which is More Secure?
