Description

technical field [0001] The invention relates to the field of mobile network security, in particular to an image data leakage prevention method, device and equipment. Background technique [0002] Data security is more and more concerned by enterprises. Enterprises will have a lot of important data to protect. Currently, data leakage prevention mainly focuses on text data security protection. However, with the development of the information industry, the protection requirements for image data are also increasing. growing day by day. [0003] The existing anti-leakage of image data mainly uses image feature extraction based on wavelet transform technology, and recognition of text content in images based on OCR technology, so as to construct the content fingerprint of the image. [0004] Adopt above-mentioned technology to have following defective: [0005] 1. The security protection ability of image data is relatively weak. When the image is distorted and deformed, the conte...
