Abstract
The invention provides an implementation method of electronic media digital protection. When a user downloads media content, a media server analyzes a mobile phone identification code (IMEI) registered by a user and then produce a validation code related to the IMEI based on an encryption algorithm. When the user opens a media file, the mobile phone identification code (IMEI) of a mobile terminal is read out, and the result of encryption algorithm is compared with the validation code in the media content via the same encryption algorithm. If the comparison is the same, the verification is passed and the user is allowed to browse the media content, otherwise the user is not allowed to browse. The invention prevents the media content downloaded at one mobile terminal from being copied to other mobile terminals for reading and browsing.

Fig. 2 is the flow chart that generates second identifying code at mobile phone terminal of the present invention;
Fig. 3 is the electronic file form schematic diagram of media content of the present invention.
Embodiment
The present invention is further elaborated with specific embodiment with reference to the accompanying drawings below.
The present invention be directed to the media content that carries with electronic document and encrypt, the user carried out the checking of handset identification code IMEI earlier before mobile phone terminal is read this media content, whether had the right to read this media content to verify this user.
The user needed to submit log-on message (comprising user ID, user cipher, user mobile phone fuselage identification code IMEI) by mobile phone terminal to media server before media content download.Terminal program can get access to the handset identification code IMEI of mobile phone terminal automatically and append in the log-on message, submits to media server then.Media server will store these log-on messages in the database into correspondingly.
Handset identification code IMEI generally is made up of 15 Arabic numerals, the character string of each mobile phone terminal of unique identification, that is to say that different mobile phone terminals has different handset identification code IMEI, as shown in the table, in the user message table of database, wherein two users' different handset identification code IMEI have been write down.
| User message table (user_info_t) | ? | ? |
| User ID (userid) | User cipher (password) | User mobile phone IMEI (imei) |
| 10001? | 123456? | 355694006548664? |
| 10002? | 654321? | 355694006548665? |
As shown in Figure 1, when the user asks media content download, media server is according to the user ID in the user's registration information, Query Database is to obtain handset identification code IMEI (if media server is looked into when can not find corresponding handset identification code according to the user's registration information Query Database, then return error message) to this user, generate first identifying code by default cryptographic algorithm, and this first identifying code write in the media content, again the document of this media content is sent to mobile phone terminal.Described default cryptographic algorithm can be TEA (Tiny Encryption Algorithm is called for short TEA) cryptographic algorithm or other cryptographic algorithm.
For example, during user's 10001 request media content downloads, media server is according to user ID (10001) Query Database, the handset identification code IMEI that obtains user 10001 is 355694006548664, if adopt the TEA cryptographic algorithm, because it is 16 bytes that the TEA cryptographic algorithm requires password, so can fill one 0 in handset identification code IMEI back, promptly 3556940065486640, just can obtain the binary data xxxxxxxxxxxxxxxx (i.e. first identifying code) of one 16 byte like this by the TEA cryptographic algorithm, and these binary data are added in the electronic document of media content, the electronic file form of media content is as shown in Figure 3.
When the electronic file form of carrying media content is set, generally can reserves certain position and be used to deposit the identifying code that the handset information of identification code generates through default cryptographic algorithm.
