Embodiment 1

[0026] In this embodiment, the signature client computer and the seal verification client computer are connected to the seal server Seal Center through the network, and the seal server is connected to the CA center certificate directory server CA Center through the network. The physical seal made according to the graphic electronic seal stored in the seal server is fixed under the seal body of the combined seal, so the traditional stamping and signature can be completed on the paper document document. Simultaneously, a memory chip with USB is arranged on the seal body to store the digital certificate of the corresponding electronic seal and its private key. The entire procedure of applying the combined seal with electronic seal digital certificate to sign and authenticate can be divided into two processes of signing and checking the seal (see Figure 2), and the steps of the signing process are as follows:

[0027] 1), opening steps: the seal user opens the original office docu...
