Description

Protected file access method and system for free file security control software

The invention relates to a method for managing rights of a protected electronic file and a system thereof, in particular to a protected file access method and system thereof for the installation-free file security control software.

One of the conventional ways of protecting privileges management of electronic archives is to install an encryption and decryption application (AP) on the client. The user needs to input the account number and password to access the file, and the encryption/decryption program queries the authentication server (Authentication, Authorization & Accounting Server) by using the account and password input by the user to identify the account. User identity. When the identity authentication is passed, the authentication server will pass the user's corresponding rights (rights, the authorization obtained by the person outside the organization), or the authority (privileges, the authorization obtained by the person within the organization) to the client. End application. At this point, the application will determine the actions that the user can perform on the file, such as read-only, writable, printable, etc., depending on the rights or permissions returned.

It can be seen from the above that a protected file is required to be installed by the user to install a corresponding file security control software, and the above-mentioned authentication can read (or modify) the electronic file. Installing the encryption and decryption application software is an additional burden.

In view of the above-mentioned technical deficiencies, the present invention provides a system and method. Under this method, the client can exempt the installation file security control software but can access the protected electronic file.

The technical problem to be solved by the present invention is that the protected file can still be accessed if the client can install the file security control software. The invention mainly utilizes the browsing tool already existing on the user-side operating platform to read the protected file, so that the user can enjoy the convenience of authenticating and reading the file without the need to additionally install the related software.

In order to solve the above problem, the present invention allows a user to access a protected file by connecting to a web server with a web browser. The method includes the following steps: (a) opening a web browser program on the user end, Linking to the web server via a network, the web server provides a virtual application service via the network; (b) the virtual application service is activated for reading in response to the protected file selected by the user end An application of the protected file, and opening the protected file; (c) transmitting the opened file image to the user end for the user to operate on the web browser program.

In order to solve the above problem, the system of the present invention allows a user to access a protected file by connecting to a web server with a web browser. The system includes: a first person, transmitting the protected file to a network. Retrieving, by the server, a location of the protected file, and notifying the user of the location by using a network; the user end, opening a web browser program to connect to the a web server that provides a virtual application service via the network in response to the protected file selected by the user end, and the virtual application service launches an application for reading the protected file And opening the protected file, and transmitting the opened file image to the user end for the user to operate on the web browser program.

Other detailed features and characteristics of the present invention will be apparent from the description of the following methods or embodiments of the end system and the scope of the claims.

The web browser program 250 (or virtual file editor) is selected from an extensible markup language (XML) having (supportable) programmable and interactive functions, and the expandable Markup languages include Hypertext Markup Language (HTML 5) or those with similar functionality. The virtual application service 250 is, for example, a remote desktop. The remote desktop is installed, for example, a file reader, and includes a reader such as a word, an excel, or a powerpoint.

The method further includes the step (d): the operation of the user terminal 25 on the web browser program 250 is passed back to the virtual application service 230.

In this way, the user terminal 25 does not need to install any new software, and the protected file can be read by using the original browsing tool, and the file itself is also subject to the copyright authority management program installed on the network server. protection.

As shown in FIG. 3, the protected file access method of the second embodiment of the present invention includes steps (a), (b) and (c); wherein the (a) step is performed: at the user terminal 25 Opening a web browser (browser) 250, connecting to the web server 23 via a network and sending the protected file 210 to the web server 23, the web server 23 providing a virtual application Service 230; (b) Step execution: In response to the protected file 210 sent by the user terminal 25, the virtual application service 230 launches an application for reading the protected file 210 and opens the protected file. File 210; (c) Step execution: Transfer the opened file image to the user terminal 25 for the user to operate on the web browser program 230.

The web browser program 250 (or virtual file editor) is selected from an extensible markup language (XML) having (supportable) programmable and interactive functions, and the expandable Markup languages include Hypertext Markup Language (HTML 5) or those with similar functionality. The virtual application service 250 is, for example, a remote desktop. The remote desktop is installed, for example, a file reader, and includes a reader such as a word, an excel, or a powerpoint.
