[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0021] Figure 1 A flowchart of the electronic signature method provided by an embodiment of the present invention is shown. Figure 1 The electronic signature method provided by the embodiment of the present invention includes:

[0022] S101, the device to be signed obtains the file to be signed, and obtains the first position information of the device to be signed.

[0023] Specifically, the device to be signed in the present invention can be a PAD, a notebook computer, a PC, or other device with a visual function that can view the content of the document to be signed.

[0024] The device to be signed can pre-store the document to be signed, or receive the document to be signed sent by a third-party device.

[0025] The device to be signed can locate its own first position information through GPS positioning or Beidou positioning.

[0026] S102, the device to be signed establishes a communication connection with the signing device, and sends the first location information to the signing device.

[0027] Specifically, the device to be signed can establish a connection with the signing device through a wired or wireless method, such as USB, NFC, Bluetooth, etc. The device to be signed sends the first location information to the signing device through the established communication connection.

[0028] S103, the signing device obtains the second position information of the signing device, and determines whether the first position information and the second position information meet the preset conditions. If they meet the preset conditions, the signature information is sent to the device to be signed, and the signature information includes the second position information and the seal image.

[0029] Specifically, the signature device has a signature chip, and a seal image is stored in the signature chip.

[0030] As an optional implementation provided by the embodiment of the present invention, the signature device includes but is not limited to: a smart key device, an electronic signature pen or a physical seal. If it is a smart key device, it can be in the form of, for example, a USB Key or a Bluetooth Key. If it is an electronic signature pen, the electronic signature pen can perform handwritten signatures on the device to be signed, and can also perform electronic signatures. If it is a physical seal, the electronic seal signature function is added on the basis of the existing physical seal, and the management rules for the use of seals can remain unchanged, that is, it can be stamped with a physical seal or an electronic seal, and the action of stamping on the device to be signed with the physical seal can be the same.

[0031] The signature device can locate its own second location information through GPS positioning or Beidou positioning, and determine whether the first location information and the second location information are within a preset range. If they are within the preset range, it is considered to meet the preset conditions, otherwise it does not meet the preset conditions.

[0032] The signature device will only allow the signature information to be sent to the device to be signed after it determines that the preset conditions are met, ensuring that the document to be signed and the signature device are in the same location to avoid abuse of the electronic signature.

[0033] As an optional implementation of the embodiment of the present invention, after the preset conditions are met and before the signature information is sent to the device to be signed, the electronic signature method provided by the embodiment of the present invention further includes: the signature device obtains authorization information. Specifically, the signature device can receive information such as a confirmation password and a confirmation fingerprint, and only after the signature device verifies and obtains the authorization information can the signature information be sent to the device to be signed, so as to prevent the electronic seal from being used without authorization.

[0034] S104, the device to be signed processes the signature information and the file to be signed to obtain a signed file.

[0035] As an optional implementation of the embodiment of the present invention, before the device to be signed processes the signature information and the document to be signed to obtain the signed document, the electronic signature method provided by the embodiment of the present invention further includes: the device to be signed obtains a confirmation instruction. Specifically, after receiving the confirmation instruction, the device to be signed can stamp the seal image at the corresponding position of the document to be signed.

[0037] Specifically, the signing device may extract the number of the signed file from the signed file, or may receive the number of the signed file input by the user, or may receive the number of the signed file sent by the device to be signed.

[0038] The signature device can store the signature file number and hash value to reduce the amount of data storage.

[0039] The signing device can regularly upload the number and hash value of the signed document, for example, to the blockchain, to ensure that the signed document is traceable. The signed document with the number of the signed document can be sent to the backend by the device to be signed.

[0040] It can be seen that through the electronic signature method provided by the embodiment of the present invention, the signing device determines that the positions of the signing device and the device to be signed meet the preset conditions before allowing the signature information to be sent to the device to be signed, ensuring that the file to be signed and the signing device are in the same position, thereby avoiding abuse of the electronic signature.
