1. What are the playback watermarks of video encryption software?
Watermarking refers to adding certain digital information to data multimedia (such as images, sound, video signals, etc.) to achieve document authenticity identification and copyright protection. The embedded watermark information is hidden in the host file, without affecting the original file's viewability and integrity. So many kinds of watermarks can be added in video encryption, such as the copyright holder LOGO, any location warning language, text ads, and running watermarks. Adding watermarks enhances the difficulty of video cracking, increases the operating cost of the pirates, and reduces the probability of the video being cracked.
2. How to encrypt and play online website video?
For example, the encryption and decryption code of OTT Maker's online flash website video is based on C++ and keyframe encryption to prevent reverse cracking. The video files are encrypted in batch and also support URL encryption, which restricts the playback only under the domain name required by the copyright holder to further ensure the safety of the files.
3. How to encrypt the video files distributed offline?
Encrypting video files distributed offline is the most frequently used encryption requirement. The general process is that the video owner uses special encryption software to encrypt the video, and the video is issued to the demander. The demander plays it in the specified encrypted player. Further authorization confirmation is required before playback. At this time, the owner can set up the permitted playback time, permitted number of times, permitted bound devices, permitted offline access, etc. The video demander can only obtain the encrypted video, specified player, and valid authorization information to play the video offline.
4. Can Q&A and interactive animation be added during the video playback?
Yes. We support the automatic pop-up questions or embedded interactive flash animation at specified times during the video playback. Only when you answer correctly or complete the interaction can you continue to watch. Even the more interactive questions are inserted, the better the anti-recording effect is, which greatly increases the operation cost of pirates.
5. Can video encryption solve the problem of hardware recording during playback?
Software recording can be technically intervened. Hardware recording can not be completely prevented, but you can add LOGO, watermark, and running light information on the video, and set the viewing user ID floating screen. In this way, even if the video is leaked, you can find the relevant people in time to pursue responsibility. There is also a technical way to add questions or interactions in the video playback process. After the video is played to a specified point in time, the player will automatically pop up questions, requiring the viewer to answer. The viewer can only continue to play the video after answering the question correctly, otherwise the viewer will be banned.
The above is some of the video encryption technology knowledge based on OTT Maker's many years of video development cases, hoping to help you.
