Cross-Internet file secure sharing method and system based on HTML5 technology

Abstract

The invention discloses a cross-internet file secure sharing method and system based on an HTML5 technology, and belongs to the technical field of data encryption. According to the invention, through the cooperation of the cloud storage device and the password verification of the webpage end, the file encryption and secure sharing functions can be realized by using any one webpage browser supporting HTML5, and a file processing method for time-limited and time-limited downloading of the file is added, so that the immediate use capability of secure sharing of the cross-internet file can be increased, and multiple application system attributes can be adapted; the requirement for adaptability with encryption control software is lowered, the security encryption strength of the file is remarkably improved through data independent encryption link processing, binary processing of the security analysis file and coding encryption processing of a file link level; in addition, through encryption setting of the file elements, confidential storage of file pool information is achieved, and the corresponding file content protection capacity is kept to the maximum extent while the traceability processing capacity is achieved.

Description

technical field [0001] The invention belongs to the technical field of data encryption, and in particular relates to a method and system for safely sharing files across the Internet based on HTML5 technology. Background technique [0002] With the development of Internet communication technology, the network security problem of Internet communication has gradually become prominent. The size of files transmitted on the Internet is gradually increasing, but the security of file transmission is not well controlled, and there is a lack of good control over file encryption. [0003] Electronic files in the Internet environment are formed in a network constructed by digital devices, stored in digital form on media such as hard disks and CDs, and rely on computers and other electronic devices to read and process files that can be transmitted and utilized on the Internet. Electronic files It is attached to the computer system and is inevitably affected by the risk of network securit...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the common file encryption method to be provided by the compression tool including RAR or self-defined encryption software, the password of file encryption is input by the user; After receiving the encrypted file, the receiver needs to use the same Compression or encryption software for decryption, it is obviously difficult to have the same compression software or encryption software among many Internet office users, and a method and system for cross-Internet file security sharing based on HTML5 technology is proposed
