Abstract
The present invention discloses a method of encryption and decryption on electronic files in order to increase the security and the convenience when electronic information is transmitted and used. Divided into three steps, the method utilizes the identification code of a communication terminal as a key to encrypt the data content of an electronic file transmitted via a communication network. Firstly, a user registers an owned telephone number as a key (K) on a media server; secondly, the media server adds the key (K) into the electronic file that is then sent back to the user; and thirdly, after receiving the electronic file, a communication terminal uses the local number to decrypt the electronic file that is then played. The process of encryption and decryption on electronic files is automatic, a registered user does not feel any inconveniency of use, but the information file can only be played or read on the communication terminal of the registered user, which can prevent manifold piracies of electronic information, that is, the charged electronic files can only be obtained through a registration channel, and even the registered user cannot illegally distribute the self-obtained electronic files.
Description
Technical field
The present invention relates to communication network data information transfer field, especially relate to a kind of encipher-decipher method of mobile media data, mobile media information can be encrypted the back and send.
Background technology
Mobile flow medium service can be divided into three kinds of types of service according to the broadcast mode of data content.
---streaming media on demand (VOD).The content of multimedia encoding compression that content supplier will prerecord becomes corresponding form, leaves on the content server and the descriptor of content and link to be placed in the portal website of Streaming Media.The end user just can find interested content by visit portal website, plays selectively.
---live streaming media.The Streaming Media encoder server becomes corresponding form with the live signal encoding compression, and is distributed to user's terminal player via streaming media server.According to the difference of real time content signal source, can be divided into live telecast, remote monitoring etc. again.
---downloading and playing.The user downloads streaming medium content and store in the local terminal, can be chosen in random time then and play.For downloading and playing, main restriction index is the disposal ability of terminal and the storage capacity of terminal.What content supplier can produce better quality looks audio content (high bandwidth, high frame rate), but needs to consider the download time of content and the memory space of terminal.
As a user oriented multimedia service, commercial operation must be suggested as one of them important strategy.At first, provide streaming media service therefore need user's access information be authenticated towards authorized user.Secondly as commercial podium, the many policy, billings that must unify every service.Popular authentification of user and charge system deferred to RADIUS (Remote AuthenticationDial in User Service) agreement at present.The function that whole system mainly realizes should comprise: access authentication of user, and user's authorization of service, service process is chargeed, subscriber information management, charging policy management etc.The each several part assembly comprises certificate server, accounting server, information database, user and charging policy management platform etc.The authentification of user plug-in unit need be provided on steaming media platform, after the user passes through web authentication, also need streaming media server to carry out just watching program after the authentication, avoided the user to walk around web authentication and directly carry out program request, higher fail safe is provided with program URL address.Certificate server also forwards information to accounting server as the agency except the user right that authentication inserts.Simultaneously accounting server is according to user class, and programme information watches that period information can take different charging policy.This business makes the large-scale commercial applications operation become possibility, the new business characteristics that possess himself, for example time, flow, multiple charging regulation, multiple media formats or the like are in the user management and the higher requirement of charge system that will propose aspect selectivity, high efficiency, real-time, reliability and the fail safe than telecommunication service.
User's all kinds of program requests or direct broadcast service of using stream media system to provide for convenience, all service content can be published to the form of the Web page on the net, the user only need click the link of own required programs, just can start the client that is installed in this locality automatically and watch.Web server can be realized by technology such as Apache and PHP.To content distributed renewal, each program chaining all is a threaded file that points on the server for convenience, and the content in the file is this program in the link of the address of certain station server or scheduler.Like this, upgrade program if desired, then content gets final product in a need modification or the interpolation threaded file.
At present, safety of data is guaranteed by digital copyright management DRM.This is a kind of method that the protection content of multimedia is avoided unwarranted broadcast and duplicated.If digital publishing rights can't be guaranteed, streaming media service will lose the possibility of commercial operation.DRM is by coming protected data and judging user's rights of using by adding service regeulations to content-encrypt.
In the prior art, all come stream medium data is encrypted by the hardware encipher machine, correspondingly, user terminal is when being decrypted the stream medium data that receives, also a unique constant CEK using when encrypting of the encryption equipment of only sending according to the copyright center is decrypted, therefore, greatly reduced fail safe to the stream medium data decrypting process.The pirate phenomenon of software and electronic publication is the problem of being badly in need of urgent solution that the whole society faces, conventional software engineering cryptographic means has seemed and more and more has been pale and weak, the cryptographic means of hardware level (as softdog) is though secure on the reliability, but lack unified standard, the encryption cost is higher, and the user uses and operates also inconvenient.Nowadays the Internet era, pirate threshold will be more and more lower, the appearance of especially a large amount of pirate instruments, any domestic consumer that has no the computer technology level also can carry out copy right piracy easily, therefore pirate threat will be more and more serious.Though the legal system of country aspect combating copyright piracy is constantly perfect, hitting dynamics is also constantly strengthened, but the strike of this law aspect also is the organized copy right piracy at group's character, and for a large amount of individual copy right piracies, legal means still is difficult to prove effective.E-book reading on the later mobile phone, streaming media playing etc., more can be faced with severe piracy threatens, even paying, certain customers subscribe to positive version content, the content that this user receives own mobile phone is transmitted to other people again, still be difficult to control, if the streaming medium content of online broadcast, the user is transmitted to other people after also can recording with the mobile phone of oneself again, therefore must have a kind of mode to prevent user's this behavior.The media player that also has at present adopts binding or machine sequencing mode to encrypt, but user's inconvenient operation under this mode, and limitation is arranged.As require when playing fresh content the user to import this machine sequence number, and if user's former player damages or loses, want to change a new player, the copyright permission that the user has bought might property can be lost, and this is that the user is unacceptable.
SIM card is the abbreviation of (Subscriber Identity Model client identification module), is also referred to as smart card, subscriber identification card, and the GSM digital mobile telephone must be loaded onto this card and can use.One microcircuit chip is arranged in the SIM card, stored digital mobile phone client's contents such as information, encryption key, it can be differentiated client identity for the GSM network.
The application of SIM card in gsm system makes card separate client of a SIM card unique identification with mobile phone.One SIM card can insert in any GSM mobile handset and use, and uses the communication cost that mobile phone produced then to be recorded in automatically on this uniquely identified client's of SIM card institute the account.
The method of a mobile application permission control is difficult to obtain unique identification in PC, general unique identification can only obtain from the hard disk sequence number, and difficulty is bigger and operate constant.Tighten close the combination and move to use with Sim, telephone number becomes the best carrier of uniquely identified, by obtaining registration table
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method of e-file being carried out encryption and decryption.To improve the fail safe of electronic information in transmission and the convenience of use.And the transmission of electronic information uses with the identification code of communicating terminal and combines closely, and telephone number becomes the best carrier of uniquely identified.
In order to achieve the above object, technical scheme of the present invention is achieved in that
Encipher-decipher method when a kind of e-file is propagated in communication network is that the data content to the e-file propagated by communication network utilizes the identification code of communicating terminal to come encryption and decryption as key, and the step of encryption and decryption is:
Steps A: media server is accepted the user by the communication terminal registration of identification code is arranged, and detect the identification code of user communication terminal and it is registered as key K, and the prompting user downloads and installs the Media Browser of appointment in the communicating terminal of oneself;
Step B: that media server receives that the user sends is live, program request or when downloading the request of all kinds of media informations, server as the e-file that is packaged as the specific format that above-mentioned Media Browser supports, and adds the media information of user live broadcast, program request or download and wherein sends to the user with key K; In this process, media server can detect and send the media information program request or whether live user registers, if not registration then points out the user to register earlier.
Step C: after communicating terminal receives the e-file of above-mentioned encryption; when the user opens this e-file and reads; browser extracts key K from e-file; and from communicating terminal, extract this machine 6 identification codes, key K and this identification code are compared, if comparative result is identical; opening e-file reads for the user; if the comparative result difference has copyright protection to this e-file of user prompt, the user can read authority to the media server application.
Above-mentioned communicating terminal can be a communication terminal, and correspondingly, described identification code is the smart card telephone number on this communication terminal, and promptly user's phone number is related with SIM card, has uniqueness.
Above-mentioned communicating terminal also can be the fixed-line phone network terminal, and correspondingly, described identification code is the telephone number of this fixed-line phone network terminal, and this is just irrelevant with concrete phone, only relevant with the telephone number of specific circuit, also has uniqueness.
Among the above-mentioned steps A, user's logon mode be following any one:
(1) send the note registration by communicating terminal, this is a method the most easily;
(2) voice call registration is dialed in communication, can be robocall, also can manual service;
(3) communication internet registry, but the user wants the telephone number of incoming traffic terminal, media server sends the registration identifying code to user's communicating terminal, the user imports correct pass code and just can succeed in registration, therefore uniqueness is cannot say for sure in internet registry, therefore must have by user's communicating terminal and verify, guarantee that the registrant is the real user of communicating terminal.
Further improvement in the technical proposal is: the registered user is when media server request program request or direct broadcast service, if this service charge, then e-file is deducted information charge by the rate that is provided with in the system after being received successfully by the user, this rate is formulated by the operation of media server, and announces to the registered user.
Further improvement in the technical proposal is: the user can be provided with to the media server program request or the direct service password of service, when later user asks above-mentioned service, must the correct service password of input, otherwise the media server refusal provides service.The communicating terminal that can prevent the user is illegally used by other people like this, downloads pay imformation, causes communication fee to the user.If when the user guarantees that communicating terminal is used safely in own hand, password can be set, can save the trouble of input password so in use.
Further improvement in the technical proposal is: the user is to the media server IP Information On Demand time, the specific medium of program request temporarily information, also can customize up-to-date media information conditionally, increase when meeting the media information of user's program request condition in the vod server later on,, and key K added wherein send to the user this information package by the customization requirement.If charge when user's interim program request specific medium information and IP Information On Demand, then formally sending the affirmation message that pay imformation forward direction user sends a relevant charge to the user, after the user replys affirmation, charge again the sending of media information, the transmission of acknowledge message here and reply and can be undertaken by short message mode.
When the encrypted media information that the registered user can also obtain oneself paying is represented to other users, carry out as follows:
Step 1: the user carries out on this machine browser and represents order, and is given in the telephone number to add in target and one or morely concrete will accept the telephone number that this represents media information;
Step 2: this machine extracts the e-file numbering of the media information that will represent, and adds and given user's telephone number, sends to the service centre of representing of media server as the information of representing;
Step 3: represent that service centre receives that the user sends represent information after, in media server, extract the media information content that will send by the e-file numbering, and in the information of representing, extract and given number, to be given number as key K, be bundled to send in the media information and given on the number, after sending successfully, these medium of deduction are represented expense from registered user account;
Step 4: after the communicating terminal of being given the user receives the e-file of above-mentioned encryption, given the user when opening this e-file and reading, if file format can't be discerned, turn to step 5, otherwise continue this step, browser is to extract key K from e-file, and from this communicating terminal extraction my phone numbers, key K and my phone numbers are compared, if comparative result is identical, opens e-file and read, if the comparative result difference for giving the user, to being given this e-file of user prompt copyright protection is arranged, can or go out the person of giving to media server and apply for reading authority to information;
Step 5: communicating terminal shows the text prompt of representing in the information, and the user downloads and installs this media information to particular address reading and browsing device is given in prompting.
In above-mentioned steps 3, if being the user, the media information that the user will represent obtains by charge method, then send a relevant affirmation message of representing charge the formal request of the representing forward direction user who carries out the user, after the user replys affirmation, carry out user's the request of representing again, transmission of acknowledge message here and answer can be undertaken by short message mode.
In technique scheme, if user's program request or the media information of representing are free, then add free mark in the key K automatically, this moment, browser can directly be opened the media information file for user's reading, do not carry out key and detect comparison procedure, do not carry out the process of deducting fees yet.
Further improvement in the technical proposal is: the information of user's program request can be made as and send on user's the communicating terminal after off-line is read the formula e-file, or be online live video or audio-frequency information, this moment is only at detection key K when user live broadcast begins.
Further improvement in the technical proposal is: the e-file numbering of the media information that the automatic minute book machine of this machine browser was successfully read or represented, the user is once more when media server is downloaded the e-file of identical numbering later on, or, no longer charge when being given the media file that number represents same sequence number to identical once more.
Further improvement in the technical proposal is: can add a plurality of registered users in the e-file or be given user's telephone number as many secret key encryptions file.Such file can be downloaded by a plurality of users, or freely propagates, and has reduced the live load of media server, has improved the utilization of electronic documents rate simultaneously.
