The popularity of machine learning, AI and the network has greatly facilitated life, but there are also many security risks, and users' privacy data have been greatly threatened. At present, this kind of problem is generally solved by using big data (BD) security and privacy protection model. However, the traditional BD security and privacy protection model also has its shortcomings. For example, when facing data privacy attacks and big data information intrusion attacks, the protection effect of traditional models is not ideal, and the protection speed for privacy is too slow. Through its shortcomings, the current BD security and privacy protection model is difficult to protect the current data privacy. The research on BD security and privacy protection model based on imageencryptionalgorithm has become a hot field. Because of the advantages of imageencryptionalgorithm in data encryption, it can be applied to BD security and privacy protection model. This paper proposed a BD security and privacy protection model based on imageencryptionalgorithm, which aimed to improve the protection capability of the privacy protection model. The algorithm proposed in this paper was an image encryption algorithm based on chaotic system. Through this algorithm, the pixel correlation coefficient of the image can be reduced more thoroughly, and the user's image privacy and information can be encrypted better. In the test, the protection rates of traditional BD security and privacy protection model and BD security and privacy protection model constructed by image encryption algorithm based on chaotic system against tuple attacks were 75.15% and 82.25%, respectively. Its protection rates against attribute attacks were 77.26% and 82.41%, respectively, and against probabilistic attacks were 76.38% and 81.97%, respectively. It can be seen that the BD security and privacy protection model based on the imageencryptionalgorithm of chaoticsystem has a higher protection rate against v
