Big data image protection method and system based on a security area

Abstract

The invention provides a big data image protection method based on a security area, and the method comprises the steps: S1, selecting a target security area through employing a target detection method, and extracting color image features; s2, a big data technology is adopted, a big data picture set is utilized to train a network model and a test network model, an application algorithm of a deep learning model in target detection is applied, and an object area is extracted to serve as a safety area of information protection; and S3, taking the extracted security area as a steganography area ofthe encrypted image, and carrying out secret information hiding by applying a steganography algorithm. According to the invention, the application algorithm of the deep learning model is applied in the target detection, that is, the Mask R-CNN instance segmentation method, and select the region with complex texture noise in the image, an area with complex texture noise in the image, namely a foreground part, is selected, secret information is accurately hidden in a foreground object, and therefore the purpose of more secret image secret information hiding protection is achieved.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a large data image protection method and system based on a security area. Background technique [0002] With the rapid development of science and technology, computer network, multimedia technology and personal mobile communication technology have been widely used by everyone. A large amount of multimedia information is transmitted by people more conveniently and quickly in the network, which is convenient for everyone's communication and exchange. However, while multimedia information brings convenience to people's life, information security issues such as personal privacy being spied on and disseminated are gradually becoming more and more serious. aroused people's great attention. In recent years, some information security problems have been solved to a certain extent by information hiding technology. This method hides the secret information in a carrier medium (i...

Problems solved by technology

This method is most similar to the method of the present invention, but the faster rcnn in this method can only realize the identification of the rectangular frame of the foreground object. After information hiding, it is equivalent to hiding the secret information in the rectangular frame containing the object, which is not completely Achieve the purpose of hiding secret information into foreground objects
