In the embodiment of the invention, the first user can stamp the electronic seal on the Web page through the stamping control on the client of the first user, wherein the stamping control can be an executable component. Here, the data of the electronic seal may include at least one of a name of the seal, a color of the seal, a size of the seal, a certificate bound to the seal, and signature information of a seal maker, in addition to the stamp image. Specifically, a client of a first user can call a stamping control to enable the stamping control to complete the operation of stamping an electronic seal on a Web page; the client of the first user can also insert a stamping control into the Web page, so that the stamping control can complete the operation of stamping the electronic seal on the Web page. When the stamping control executes the operation of stamping the electronic seal, the embedded window is operated, so that the embedded window is displayed on the Web page, and then the stamping control can acquire the data of the electronic seal and render and display the electronic seal in the embedded window according to the data of the electronic seal. Specifically, in 210, drawing the electronic seal refers to rendering the electronic seal. In addition, when the data of the electronic seal only comprises the stamp image, the stamping control can draw the electronic seal in the embedded window directly according to the stamp image; when the data of the electronic seal comprises the stamp image and other data, the stamping control can analyze the data of the electronic seal to obtain the stamp image, and then draw the electronic seal in the embedded window according to the stamp image. And the stamping control draws the electronic seal in the embedded window according to the data of the electronic seal, the data of the electronic seal is still kept in the stamping control, and a user cannot acquire the data of the electronic seal through the embedded window. In addition, the way for the stamping control to obtain the data of the electronic stamp may be from a cryptographic device, or from a server, which is not limited herein, where the cryptographic device may be at least one of a smart cryptographic Key (USB-Key), an IC Card (Integrated Circuit Card), a fingerprint device, an optical disc, or a floppy disc.
For example, the first user browses the Web page through a browser, and a seal button may exist on an interface of the browser. When a first user clicks a stamping button, a stamping control is inserted into a Web page, and the stamping control starts to execute the operation of stamping an electronic seal on the Web page. Specifically, after the Web page is inserted into the stamping control, the stamping control operates the embedded window to enable the embedded window to be displayed on the Web page, and then the stamping control draws the electronic seal on the embedded window according to the data of the electronic seal to enable the electronic seal to be displayed on the Web page.

Here, the electronic seal is applied to the Web page, and the electronic seal is displayed on the Web page, and the signature is applied to the Web page to ensure the validity of the content of the Web page. Specifically, the stamping control may sign the Web page to generate a digital signature, where the principle of the signature may be based on a Public Key Infrastructure (PKI) system.
For example, the embedded window may be moved, and when the electronic seal is displayed at an inappropriate position on the Web page, the first user may drag the embedded window to display the electronic seal at the appropriate position on the Web page. After the position of the electronic seal displayed on the Web page is determined, the first user can right click on the embedded window to pop up a menu, and the menu can contain a signature option. The first user selects the signature option and the stamping control may begin signing the Web page. Here, the signature option may also be called a stamping option, and is only a difference of nomenclature, and is not limited herein. The specific process of signing the Web page by the seal control may include: the stamping control uses a hash function to operate all or part of the content of the Web page to generate a hash value; and carrying out encryption signature on the hash value by using a signature private key corresponding to the data of the electronic seal to generate a digital signature, wherein the digital signature can be referred to as a second digital signature hereinafter. The signature private key corresponding to the data of the electronic seal may be stored in the password device, and the first user may connect the password device with a client of the first user before performing the signature operation.
And 230, submitting the data and the digital signature of the electronic seal to a server, wherein the server is used for providing the Web page.
For example, after the Web page has been stamped with the electronic seal, the stamping control may directly submit the data of the electronic seal and the digital signature to the server. In addition, a submission button can be arranged on the interface of the Web page, and after the Web page is stamped with the electronic seal, the first user can click the submission button, and the stamping control submits the data and the digital signature of the electronic seal to the server. Or the first user can click a submit button, and the browser submits the data and the digital signature of the electronic seal to the server. The manner of submitting the data of the electronic seal and the digital signature to the server is not limited thereto. The data submitted to the server by the client of the first user can include other data, such as at least one of seal position information, page filling content, stamping control and the like, besides the data of the electronic seal and the digital signature.
According to the technical scheme provided by the embodiment of the invention, the electronic seal is drawn on the embedded window of the Web page according to the data of the electronic seal, the Web page is signed, the digital signature is generated, and the data and the digital signature of the electronic seal are submitted to the server, wherein the server is used for providing the Web page, the electronic seal is drawn on the embedded window of the Web page by using the data of the electronic seal, the drawn electronic seal is only the display result of the electronic seal and does not contain the data of the electronic seal or the link of the data of the electronic seal, so that a user cannot obtain the data of the electronic seal from the embedded window, and the seal of the Web page is effectively prevented from being illegally obtained and used.
In another embodiment of the present invention, the implementation method of fig. 2 may further include: acquiring seal position information, wherein the seal position information is used for indicating the position of the embedded window relative to the Web page, and submitting data and a digital signature of an electronic seal to a server, and the seal position information comprises the following steps: and submitting the data, the digital signature and the seal position information of the electronic seal to a server.
For example, the stamping control can obtain the stamp position information while signing the Web page. Here, the stamp position information may refer to a position of the embedding window relative to the Web page when the stamping control signs the Web page, and the position may be a suitable position where the electronic stamp is displayed on the Web page.
Because the stamp position information can indicate the position of the embedded window relative to the Web page, when the content of the Web page is verified to be tampered, the stamping control can automatically move the embedded window to the position specified by the stamp position information according to the stamp position information, so that the electronic stamp can be displayed at the proper position of the Web page.
In another embodiment of the present invention, an electronic seal is drawn in an embedded window of a Web page according to data of the electronic seal, and the method of fig. 2 may include: acquiring and analyzing data of the electronic seal to obtain a stamp image; and drawing the electronic seal on the embedded window according to the stamp picture.
For example, when the data of the electronic seal includes at least one of a name of the seal, a color of the seal, a size of the seal, a certificate bound to the seal, signature information of a seal maker, and the like in addition to the stamp image, the stamping control may obtain and analyze the data of the electronic seal to obtain the stamp image, and then draw the electronic seal in the embedded window according to the stamp image, so that the electronic seal is displayed on the Web page. Specifically, the stamping control can draw the electronic stamp in the embedded window according to the stamp picture, and the stamp picture is still kept in the stamping control, so that a user cannot obtain the stamp picture through the embedded window.
The stamping control acquires the stamp image by analyzing the data of the electronic stamp, and then draws the electronic stamp in the embedded window according to the stamp image, wherein the drawn electronic stamp is only the display result of the electronic stamp and does not contain the stamp image or the link of the stamp image, and a user cannot acquire the stamp image through the embedded window, so that the stamp of the Web page is effectively prevented from being illegally acquired and used.
In another embodiment of the present invention, before signing the Web page, the implementation method of fig. 2 may further include: using a signature public key of a seal maker to verify whether the data of the electronic seal is legal or not, wherein the signature of the Web page comprises the following steps: and when the data of the electronic seal is verified to be legal, signing the Web page.
For example, in order to ensure the validity of the data of the electronic seal, when the signer makes the electronic seal, the signer may first receive the seal metadata of the electronic seal, and then use the signature private key to sign the seal metadata to generate a digital signature, which is the signature information of the signer, and the digital signature may be referred to as a first digital signature hereinafter. At this time, the data of the electronic seal may be classified into two types, which are seal metadata and signature information of the seal maker, where the seal metadata includes a stamp image, and in addition, may include at least one of a seal name, a seal color, a seal size, or a certificate bound to the seal. Before signing the Web page, the stamping control can firstly verify whether the data of the electronic seal is legal by using the signature public key of the stamping party, and when the data of the electronic seal is legal, the stamping control signs the Web page. The signature private key is owned by the signer and can be called as the signature private key of the signer. The signature private key of the signer and the signature public key of the signer form a signature key pair of the signer. The signature public key of the signer can be obtained from the signer, and the specific way is not limited here. The process that the stamping control uses the signature public key of the stamping party to verify whether the data of the electronic seal is legal or not can comprise the following steps: the stamping control uses a hash function to operate the stamp metadata to generate a first hash value; the stamping control uses a signature public key of a stamping party to verify and sign the first digital signature to generate a second hash value; and the seal control compares whether the first hash value and the second hash value are consistent, and if so, the verification is legal.
Before the electronic seal is stamped on the Web page, whether the data of the electronic seal is legal or not is verified, and the validity and the legality of the electronic seal stamped on the Web page can be ensured.
