The following embodiment of the disclosure proposes a kind of user profile when accessing IPTV based on IPTV user and carries out AES(Advanced Encryption Standard, Advanced Encryption Standard) encrypt the URL(Universal Resource Locator generating user's access, Universal Resource Locator); User accesses CDN(Content Distribution Network, content distributing network) time, URL is carried out to the parsing verification of user access information, after verification succeeds, just permission CDN provides streaming media service for this user.
Fig. 1 is the schematic flow sheet that the use IPTV of a disclosure embodiment carries out the method for streaming media on demand.
As shown in Figure 1, this embodiment can comprise the following steps:
S102, IPTV platform receives the broadcasting URL request that user terminal is initiated, and extracts user access information from playing in URL request;
Particularly, user terminal is as thought a broadcasting flow-medium, and first it initiate to play URL request to IPTV platform, can include but not limited to user access information in this request.Wherein, the IP address that user access information can include but not limited to user ID again, user terminal uses and access time stamp.Access time stamp for user initiate broadcasting URL request time.
S104, IPTV platform is encrypted the user access information extracted.
User access information after encryption adds in the URL that user terminal asks by S106, IPTV platform, and the URL being added with the user access information after encryption is fed back to user terminal;
Particularly, legal identity is utilized to usurp the URL link of a broadcasting flow-medium from IPTV platform in order to prevent user terminal, IPTV platform is encrypted the user access information carried in application, and certain position of being added in the URL that IPTV platform and CDN arrange, like this, due to feed back to user terminal URL address in comprise enciphered message, therefore user terminal just can not unrestrictedly use this URL address after getting the URL address for a broadcasting flow-medium.Such as, this URL address can not be shared with other disabled users and use, arbitrarily can not change user terminal, and indefinitely can not use this URL address.
S108, CDN receive the streaming media on demand request that user terminal is initiated, and carry the URL that IPTV platform feeds back to user terminal in streaming media on demand request;
Particularly, user terminal, behind the URL address receiving IPTV platform feedback, is directly transmitted to CDN.
S110, CDN extract user access information in the URL received, and are decrypted the user access information extracted;
Particularly, CDN extracts user access information according to the position of arranging with IPTV platform in URL, and utilizes PKI to be decrypted user access information.
It is pointed out that can be updated periodically IPTV encryption deciphers the PKI used, to ensure fail safe further with CDN.
S112, CDN verify the user access information after deciphering according to streaming media on demand request, after verification succeeds to mobile terminal send ask the Streaming Media of program request;
Particularly, the user access information decrypted can be compared with the information of carrying in streaming media on demand request, to verify the legitimacy of streaming media on demand request item by item.
In this embodiment, because IPTV platform will add in the URL asked after user access information encryption, the address not only comprising access stream media in the URL that user terminal is obtained from IPTV platform also comprises enciphered message, and therefore user terminal can not be usurped and utilize this URL.CDN, after receiving the URL comprising enciphered message, first verifies enciphered message wherein, provides the Streaming Media of institute's program request after being verified again to user terminal, and then ensure that the fail safe of video link.
Wherein, in step S112, CDN according to streaming media on demand request to deciphering after user access information verify, after verification succeeds to mobile terminal send ask the step of the Streaming Media of program request to comprise:
Because user terminal can carry user ID when CDN initiates streaming media on demand request, therefore, the user ID of carrying in the user ID in the user access information after deciphering and streaming media on demand request can be compared, to guarantee that the user initiating to play URL request and initiate streaming media on demand request is same user;
Because CDN can know the IP address of the user terminal sending this request to the streaming media on demand request that it is initiated according to user terminal, therefore, if two user ID are identical, the IP address that the IP address then used by the user terminal in the user access information after deciphering uses with the request of transmission streaming media on demand compares, to guarantee that the user terminal of initiating to play URL request and initiate streaming media on demand request is same terminal;
If two IP addresses are identical, then judge the access time difference of stabbing in the user access information after present system time and deciphering whether in effective timeliness, if in effective timeliness, then to mobile terminal send ask the Streaming Media of program request, user's program request same flow media content indefinitely can be prevented like this.
In addition, in step S104, IPTV platform can comprise the step that the user access information extracted is encrypted:
Aes algorithm is utilized to be encrypted the user access information extracted;
Based on Base64 mode, the user access information after encryption is converted to character string;
Judge whether comprise preset characters in character string;
As comprised, then URLEncode is utilized to recode to character string;
Wherein, this preset characters is "/", in order to prevent the "/" in enciphered message and URL address from obscuring, therefore needs to carry out URLEncode to the character string containing "/" character.
It is pointed out that the user terminal in above-described embodiment can be computer (PC), STB(Set-Top Box, Set Top Box) or mobile terminal.
In an example, play the encrypted characters string increased in URL at IPTV by IPTV platform, by CDN, door chain is realized to the mode that encrypted characters string verifies again, user understands report of user ID when accessing IPTV, IP address and timestamp, and these information encryptions become encrypted characters string to add in the parameter of request program URL, when user adopts and comprises request content broadcasting in URL to the CDN of door chain information, CDN checks URL, namely, from playing URL the encrypted characters string obtained in URL parameter, user ID corresponding to encrypted characters string is gone out by public key decryptions, IP address and the access time stamp after, verify again.After validated user have passed the inspection of door chain mechanism, CDN carries out Streaming Media transmission immediately, otherwise refusal is pushed Streaming Media by CDN.The key that IPTV platform and CDN use supports regular update, use secret key encryption door chain packets of information containing user profile such as user ID, IP address, access time stamps, the generating algorithm of encryption string is as follows: encryption string (Key)=AES(USERID+ " $ $ "+IP+ " $ $ "+TimeStamp, key).
