Embodiment 1

[0064] A method for binding e-books to handheld readers.

[0065] People use mobile terminals such as handheld readers to read e-books. As a kind of digital content, e-books need to obtain the authorization file of the corresponding e-books to read after adding copyright protection. Therefore, the handheld reader needs to download the authorization file, but because the handheld reader generally lacks Internet communication capabilities, it cannot directly download the authorization file bound to its own device from the copyright server.

[0066] Therefore, using the method of the present invention, the handheld reader can bind the e-book and the handheld reader through the PC.

[0067] For example: a reader purchases an e-book B from an online e-book store, and can read it on a handheld reader, but needs to obtain the content file B1 of e-book B and the authorization file B2 of e-book B through a PC, and the handheld reader It can be connected to a PC through a USB data cabl...

Embodiment 2

[0087] How to bind e-books to mobile phones.

[0088] People can also use mobile terminals such as mobile phones to read e-books. Similarly, when reading an e-book with copyright protection on a mobile phone, the mobile phone also needs to obtain the authorization file of the e-book to read it. The mobile phone has a certain Internet communication capability, but due to the slow download speed of the mobile phone, or the limitation of the mobile data network and the Internet, it is very difficult to download the authorization file from the copyright server. Utilizing the method of the invention, the mobile phone can bind the authorization file of the electronic book with the mobile phone through the PC.

[0089] In this embodiment, a reader buys a book B from an online electronic bookstore, and can read it on a mobile phone, but needs to download the content file B1 and authorization file B2 of the electronic book B through a PC, and the mobile phone communicates with the PC ...

Abstract

The invention discloses a method for bonding an authorization file of digital content with a mobile terminal, relating to the field of intellectual property protection of digitalization content and resolving the problem that the prior mobile terminal are difficult to acquire the authorization file of digital content. The method includes that: a computer acquires the characteristic information of a mobile terminal; the computer acquires an authorization file of digital content with the authorization file containing the characteristic information; and the computer delivers the authorization file to the mobile terminal. The invention downloads the authorization file in the network via the computer with no need of strengthening the communication ability of the mobile terminal and no need of acquiring the authorization file manually, thereby reducing the cost of the mobile terminal, and increasing the speed the acquisition of the authorization file of digital content by the mobile terminal. The invention is mainly applied to the conditions of various mobile equipment acquiring authorization files, such as cell phones, hand-held readers, palm computers, multimedia players and so on.

Description

technical field [0001] The invention relates to a method for binding an authorization file of digital content with a mobile terminal.
