A data tamper-proof method of cloud computing platform based on blockchain

In order to solve the problems existing in traditional methods such as low tamper-proof success rate, high tamper-proof time and high resource occupation, a data tamper-proof method of cloud computing platform based on blockchain is designed. The differences of data features are obtained according to the number of data spatial dimensions to determine the importance of data features. According to the importance of data features, on the basis of cloud computing platform data denoising processing, the data feature set is constructed to complete feature extraction. Combined with the result of feature extraction, blockchain is used to construct block structure, and the tamper-proof algorithm of cloud computing platform data is designed to ensure the data security of cloud computing platform. The experimental results show that the tamper-proof method designed has a high success rate, low tamper-proof time, low resource occupation, and good practical application effect. © 2024 Inderscience Enterprises Ltd.
