Another offline digital copyright protection method realizes digital copyright protection by limiting functions of built-in application programs, such as limiting the forwarding times and opening times of digital copyright files to be protected.
An online digital copyright protection method for a mobile terminal is generally characterized in that a special watermark is embedded in a digital copyright file to be protected, and when the digital copyright file to be protected is to be read, the special watermark is acquired from a server by utilizing wireless connection of a data communication function or a Bluetooth wireless function and the like of the mobile terminal so as to verify whether the file corresponding to the watermark can be read normally.
In the prior art, a digital rights protection method of a mobile terminal is divided into offline digital rights protection and online digital rights protection. Since the third party cannot develop the application, the number of application programs on the mobile terminal and the file type of copyright protection are very limited, which cannot meet the diversification of user requirements. The online digital copyright protection method requires that the mobile terminal must be ensured to be connected to the server side when the copyright is verified, otherwise, the copyright verification cannot be completed. Thus, not only is an extra data communication fee incurred for the user each time the file is opened, but also the file cannot be opened due to failure of authentication when connection to the server is not possible in some occasions or for a period of time. Therefore, there are strong limitations to online digital rights protection methods, which are generally adopted only under specific application conditions.
