Sensitive image recognition method and device

Abstract

The invention discloses a sensitive image recognition method and a sensitive image recognition device, and belongs to the field of image recognition. The method comprises the steps of acquiring an image to be recognized; detecting whether a target image exists in a sensitive image database, and acquiring a detection result, wherein the sensitive image database is used for storing the plurality of sensitive images and the category of each sensitive image, and the target image is the image the same as the image to be recognized; predicting the category of the image to be recognized via an image recognition module, and acquiring a prediction result, wherein the prediction result comprises a plurality of categories to which the image to be recognized may belongs and the probability of each possible category; and acquiring the category to which the image to be recognized belongs according to the detection result and the prediction result. Through combination of the recognition method based on the sensitive image database and the recognition method based on the image recognition model, the new sensitive image or the sensitive image with a small spreading range can be recognized while the typical sensitive images are recognized, the recognition range of the sensitive images is expanded, and the recognition effect is good.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a sensitive image recognition method and device. Background technique [0002] With the popularity of the Internet, the Internet has become an important channel for the dissemination of various information. While users obtain a large amount of useful information through the Internet, they also obtain a large amount of bad information, such as sensitive images that are prohibited by laws and regulations such as pornography, prostitution, violence, and political sensitivity. These bad information will have a bad influence on users, therefore, it is necessary to identify sensitive images to purify the network environment. [0003] In the prior art, the process of identifying sensitive images is as follows: establish a sensitive image database, usually, the sensitive image database contains image fingerprints belonging to the same sensitive image category; when the image to be ident...

AI Technical Summary

Problems solved by technology

[0005] The sensitive image recognition method above depends on the sensitive image database, and the establishment of the sensitive image database is restricted by various conditions, such as storage resource limitations, search speed limitations, manpower limitations, etc., where the storage resources and search speed limitations of the sensitive image database do not allow Too many sensitive images added

In addition, human limitations will lead to the inability to timely review the emerging sensitive images of different categories, and then cannot update the sensitive image database in time, so that only a very small proportion of sensitive images in the actual dissemination of sensitive images can be identified based on the sensitive database

Therefore, the recognition range of the above sensitive image recognition method is narrow and the recognition effect is poor
