Media File Security in the Era of Large Data Created by the Internet of Things for Smart Cities

Big data incorporates streaming media as one of its components; regardless of how lengthy the movie is, industry-standard video encoding techniques encode a massive amount of data. When there is a possibility that the video being broadcast may be recorded and viewed by both the intended recipient and the attacker, the availability of the data as well as the identification of the audience is jeopardized. This study employs the Advanced Encryption Standard (AES) to prevent cybercriminals from accessing its data. Video data must first be compressed to make greater use of the available system resources. The multimedia container format (often known as MPG) employs three separate frame types for video compression: I frames, B frames, and P frames. The data in the second and third time periods is like what was presented in the first time. Even I frame must be analyzed and compressed to remove unneeded data. Even if it contains a large amount of new data, decrypting the entire video may only take a single frame. Encrypting a single frame takes substantially longer when many compression algorithms are used. The approach given here is superior to the alternatives in terms of encryption and data processing speed. The inversion of the equipment had no effect on the video’s quality. This design has been demonstrated to be capable of video decoding.
