Design of Digital Image Information Security Encryption Method Based on Deep Learning

Due to the high degree of overlapping of digital image information, the security encryption ability of digital image information is weak and the encryption accuracy is low. A security encryption method for digital image information based on deep learning is designed. Determine the connection form of the deep learning network, and based on this, select the key learning function, decipher the digital image information, and complete the digital image analysis based on deep learning. According to the scrambling result of the image information, a circular index table structure is established, and then the secure encryption of digital image information is realized by solving the value range of the security parameter. The experimental results show that the maximum value of the information overlapping index of this method can only reach 1.36, which has strong digital image information security encryption ability and can effectively improve the security encryption accuracy of digital image information.
