Abstract

The present invention discloses an electronic document signing method based on a fixed neural network steganography technique. The method includes that the signer uses a trusted identity authentication platform to verify the identity of the signer, and applies for a signature key using the verified identity ID, performs a digest operation on the document to be signed through a hash function to generate a document plaintext digest; uses the signature key and the document plaintext digest, and generates a signature value through an identity-based cryptographic signature algorithm; uploads the signature value, the document plaintext digest, the verified identity ID as verification values, and the signer's signature picture to a cloud platform, and the cloud platform uses the fixed neural network steganography technique to embed the identity-based cryptographic signature verification value into the handwritten electronic signature picture. The present invention can securely hide digital signature information in the picture without significantly changing the visual appearance of the signature picture, improving the security and credibility in the process of electronic document processing.
