System and method for adding real-time file dynamic tags and encryption online

Abstract

The invention discloses a system and method for adding real-time file dynamic tags and encryption online, which is used to transfer each file and add at least one tag related to the file and user information, according to The user's demand is encrypted for viewing after decryption by the user. At first, at least one file is transmitted through a data input unit; the file from the data input unit is converted into PDF format through a first conversion unit, and Adding at least one tag related to the file and user information via a tag adding unit; encrypting the file from the first file transfer unit through the encryption unit to form an encrypted file and generate a corresponding Decryption key: transmitting the encrypted file and the corresponding decryption key to a first storage unit for storage and a second storage unit for storage.

Description

technical field [0001] The present invention relates to a system and method for adding dynamic tags to files, encrypting and decrypting files, and viewing file content online, especially about allowing users to read confidential files online and read confidential files offline. Authenticity, controllability, usability, integrity, and non-repudiation performance greatly reduce the file capacity after adding labels related to user information, and use multiple high-level encryption standards to encrypt files separately, and Includes methods for optimizing the allocation of system resources. Background technique [0002] For the operation of general governments, banks, national defense, enterprises, organizations, and medical institutions, the information circulating within them refers to the information generated, collected or used by the government, banks, national defense, enterprises, organizations, and medical institutions during their operations. material. There are man...
