Signed-document encrypting and safety browsing device and method thereof

Abstract

The invention provides a signed-document encrypting and safety browsing device and a method thereof, and relates to the field of electronic document transmission. The signed-document encrypting and safety browsing device and the method thereof have the advantages that a secret key is generated when an encryption identification of a signed document is identified, the signed document is encrypted according to the secret key and an encryption algorithm to generate an encrypted document, manual encryption of users is not needed, and accordingly, user experience is good; the secret key and the encrypted document are sent to a second client side when verification information sent by each third client side is received; when a user not knowing the secret key wants to browse the encrypted signed document, the signed document and the secret key can be received by the second client side after verification of each responsible person related to the signed document, so that the content of the signed document is protected to some extent, practical document application capability is improved, and users' browsing experience is good.

Description

technical field [0001] The invention relates to the field of electronic document transmission, in particular to a device and method for signing off document encryption and safe browsing. Background technique [0002] Electronic documents refer to written materials formed by people in social activities, with chemical magnetic materials such as computer disks, magnetic disks, and optical disks as carriers. It relies on computer system access and can be transmitted on the communication network. It mainly includes electronic documents, electronic letters, electronic reports, electronic drawings, etc. However, in order to prevent some confidential or privacy-related electronic documents from being illegally obtained and leaked by others during transmission, it is necessary to encrypt the electronic documents before the electronic documents are transmitted. [0003] In the prior art, the encryption of the documents in the computer is generally done manually by the user, which req...

Problems solved by technology

[0003] In the prior art, the encryption of the documents in the computer is generally done manually by the user, which requires the user to judge whether the document needs to be encrypted, which is inconvenient in practical applications; and the user sometimes forgets to encrypt the document, which is not conducive to the security of the document ; and after the document uploaded to the computer is encrypted, when other trusted users need to consult the document, the document cannot be consulted because they do not know the key of the document; the actual use ability of the document is reduced, and the user's browsing experience Difference
