Block chain-based anti-disclosure electronic signature verification method

The invention discloses an anti-leakage electronic signature verification method based on a block chain, and relates to the technical field of data verification and encryption, and the method comprises the following specific steps: 1, collecting the basic information of an electronic signature to a block chain, managing the block chain through a convolutional neural network, and freely uploading the data of a block to the block chain, the convolutional neural network controls the output of the basic information on the block chain; step 2, performing electronic signature, setting a basic information and electronic signature storage area in the same block, and chaining the basic information and the electronic signature in the block to a block chain; 3, verifying the electronic signature, decrypting the basic information and the electronic signature on the block chain by adopting a public key, and verifying the basic information and the electronic signature by the convolutional neural network; and step 4, output
