Abstract: Multimedia Information Encryption Algorithm Based on Big Data Analysis MARDAN Zunon (Department of Information Engineering, Xinjiang Institute of Engineering, Urumqi 830023, China) Abstract: The traditional method of digital multimedia information encryption is based on the knowledge of a single mathematical field, which has some problems such as easy leakage, easy cracking and low security level. As a result, a digital multimedia information encryption method based on big data analysis is proposed. The encryption method of the cloud and encryption hardware is combined to write the digital multimedia information encryption algorithm into the cloud database. Users use cryptographic hardware for identity binding, creating isolated spaces for information interaction. Complete the encryption of digital multimedia information. The experimental results show that the digital multimedia information encryption method based on big data analysis reduces the crack rate of theoretical encrypted files and has good information encryption effect, high safety factor, and strong practicability.
