Description
Technical Field
The invention relates to the technical field of internet, in particular to a video service anti-stealing link method, a video service anti-stealing link device, a video service anti-stealing link computing device and a video service anti-stealing link storage medium.
Background
OTT (overhead) and IPTV are operation forms in which a playing terminal shares content resources with a user who purchases a service, and the playing terminals such as OTT and IPTV implement continuous real-time playing on a network in a streaming media manner, so that a video server is required to sequentially store each video file slice in real time.
However, more and more applications adopt a hotlinking mode to enrich own resources, so that the resources of a content provider can not be used by own users, but are provided for the hotlinking users, thereby not only greatly increasing the operation cost, but also destroying the perception of own users due to the paralysis of a content server caused by the hotlinking. In the existing anti-theft chain technology, the anti-theft chain is mainly realized through two directions: one direction is that the validity of each URL is verified by constructing the complexity of scheduling and allocation of Uniform Resource Locators (URLs) each time, and real Resource request addresses are allocated when the URLs are determined to be legal users, so that the method for avoiding the anti-theft chain by constructing the complexity of the URLs increases the performance burden of interactive verification of a scheduling server and a Resource server on one hand, and can not stop the cracking or counterfeiting interaction of an encryption algorithm on the other hand; the other direction is to determine whether there is a link stealing behavior by extracting and matching the feature information (such as signature information, IP information, referrer information, etc.) of the playing terminal and determining whether the feature information changes, however, since the feature information of the playing terminal is easily forged, for example, the IP information is forged by proxy, the referrer information is forged in a non-browser environment, or the signature information of the same legal member account within the expiration time is multiplexed, the video resource is transmitted to a plurality of illegal playing terminals for use.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flowchart of an embodiment of the anti-stealing link method for video services according to the present invention, which is applied in a scheduling server. The scheduling server may be a cdn (content Delivery network) scheduling server, which refers to a content Delivery scheduling server, and distributes a play request of a user to an optimal node by publishing content of a source station to an edge node, so as to obtain a required content at the highest speed and improve an access speed of the user. As shown in fig. 1, the method comprises the steps of:
step S110: and receiving a play request which is initiated by the play terminal and carries the session identifier.
In this step, the playing terminals initiate playing requests carrying Session identifiers, specifically Session IDs, specifically, after the playing terminals are authenticated by the authentication server, each playing terminal can obtain an independent and unique Session ID allocated by the authentication server, the playing terminals initiate charging messages to the authentication server according to a preset period, the authentication server updates the Session IDs corresponding to the playing terminals according to the charging messages, and further, when the playing terminals initiate playing requests to the scheduling server for video resources, each initiated playing request carries a Session ID.
Step S120: judging whether a video URL corresponding to the session identifier is stored in the memory; if yes, go to step S140; if not, go to step S130.
Specifically, each time the scheduling server receives a play request with a Session ID, it determines whether a video URL corresponding to the current Session ID is stored in the memory through memory-level storage.
Step S130: and establishing a corresponding video URL for the session identifier in the memory according to the playing request, and sending the video URL to the playing terminal so that the playing terminal can access the video resource through the video URL.
Generally, a scheduling server needs to allocate a corresponding video URL to a playing terminal according to a Session ID to facilitate the playing terminal to obtain a video source corresponding to playing content, and if a video URL corresponding to a current Session ID is not stored in a memory, a video URL with an index of the Session ID is established for the playing terminal in the memory and is sent to the playing terminal, so that the playing terminal can request a video service of a corresponding program through the video URL to access the video resource.
In an optional manner, step S130 further includes: and establishing a video URL according to the video resource corresponding to the playing request, and storing the video URL in the memory by taking the session identifier as an index.
Specifically, according to the video resource corresponding to the play request, the Session ID is used to update the index on the memory while the video URL is established, and the Session ID is used to index and store the video URL.
Step S140: and deleting the video URL corresponding to the session identifier from the memory, establishing a corresponding new video URL for the session identifier, and sending the new video URL to the playing terminal.
Specifically, if the memory of the scheduling server stores the video URL corresponding to the Session ID, the video URL corresponding to the Session ID is deleted, a new video URL is established for the video service requested by the Session ID, and the new video URL is updated and indexed on the memory to be the Session ID, that is, the new video URL is stored using the Session ID as an index and is sent to the play terminal, so that the play terminal can access the video resource through the video URL.
In an optional manner, before establishing a corresponding new video URL for the session identifier, the method further includes: informing a video server corresponding to the video URL to perform failure processing on the video URL; and receiving a failure processing success notification message returned by the video server. Specifically, the scheduling server generates a session invalidation notification message and sends the session invalidation notification message to the video server corresponding to the video URL, so that the video server stops providing service for the video URL according to the session invalidation notification message. After the video server stops serving the video URL, the video server returns a failure processing success notification message to the scheduling server so as to notify the scheduling server that the failure processing has been completed.
Specifically, the video URL corresponding to the Session ID is deleted, and the video server corresponding to the video URL is notified to perform invalidation processing on the video URL, that is, a Session invalidation notification message is sent to the video server corresponding to the video URL, and after receiving the invalidation message of the scheduling server for the Session ID, the video server invalidates the original video URL corresponding to the Session ID, stops continuing to serve the video URL, and returns the invalidation processing success notification message to the scheduling server.
By adopting the method provided by the embodiment, the playing request which is initiated by the playing terminal and carries the session identifier is received; judging whether a video URL corresponding to the session identifier is stored in the memory; if not, establishing a corresponding video URL for the session identifier in the memory according to the playing request, and sending the video URL to the playing terminal so that the playing terminal can access the video resource through the video URL; and if so, deleting the video URL corresponding to the session identifier from the memory, establishing a corresponding new video URL for the session identifier, and sending the new video URL to the playing terminal. In the embodiment, through memory-level storage and scheduling, it is ensured that only one Session ID exists as an index for each playing terminal, and that only one video URL in the current latest state exists for each Session ID, which is effective, that is, even if the original Session ID is stolen, batch-level user-scale resource reuse cannot be performed, so that the operation, server, bandwidth and storage costs of the scheduling server are effectively reduced, and only one video URL in the latest state exists in the current memory of the scheduling server, which can stably and reliably prevent the possibility of stealing links.
Fig. 2 is a flowchart illustrating another embodiment of the method for preventing hotlinking of video services according to the present invention, which is applied in a broadcasting terminal. As shown in fig. 2, the method comprises the steps of:
step S210: and receiving the session identifier returned by the authentication server after the authentication is passed.
After the playing terminal is started, the authentication server can authenticate whether the playing terminal is legal, and the method specifically includes: verifying the legality of the account number and the password of the playing terminal; and verifying whether the account of the playing terminal is expired. If the account number and the password of the playing terminal fail to be authenticated or the account number of the playing terminal expires, the authentication server sends a corresponding authentication failure message to the playing terminal; if the account number and the password of the playing terminal are successfully authenticated and the account number of the playing terminal is not expired, the authentication is passed, and the authentication server allocates a unique Session ID to the playing terminal, so that the Session ID is carried by the playing terminal to verify the validity of the playing request of the playing terminal when the playing terminal initiates the playing request each time.
It should be noted that the Session ID may be encrypted information.
In an optional manner, the method may further include the steps of: and initiating a charging message to the authentication server according to a preset period so that the authentication server updates the session identifier corresponding to the playing terminal according to the charging message, and returns the updated session identifier to the playing terminal.
Specifically, in order to prevent the Session ID from being stolen, the playing terminal may initiate a charging message to the authentication server according to a preset period, the authentication server receives the charging message initiated by the playing terminal, and updates the Session ID corresponding to the playing terminal according to the charging message, for example, the original Session ID is deleted and invalidated, and the updated Session ID is re-allocated to the playing terminal, so that the Session ID is updated in time, and the video resource is prevented from being transmitted to a plurality of illegal playing terminals for use after the Session ID is stolen. Specifically, the preset period can be manually set according to actual needs.
Step S220: and constructing a playing request carrying the session identifier, and sending the playing request to the scheduling server so that the scheduling server can determine and return the corresponding video URL according to the playing request.
In this step, the playing terminal constructs a playing request carrying the Session ID after the authentication is passed, and sends the playing request to the scheduling server, the scheduling server receives the playing request carrying the Session ID initiated by the playing terminal, the scheduling server receives the playing request carrying the Session identifier initiated by the playing terminal, and establishes a corresponding video URL for the Session ID in the memory according to the playing request, and sends the corresponding video URL to the playing terminal.
Step S230: and receiving a video URL returned by the scheduling server, and accessing the video resource through the video URL.
Specifically, a video URL corresponding to the Session ID returned by the scheduling server is received, and the playing terminal can request a video service of a corresponding program through the video URL to access the video resource.
By adopting the method provided by the embodiment, the playing terminal is authenticated through the authentication server, the only Session ID is distributed to the playing terminal after the authentication is passed, and the charging message is sent according to the preset period to update the Session ID in time, so that the possibility of Session ID forgery is prevented; meanwhile, through memory-level storage and scheduling, each playing terminal is ensured to have only one Session ID as an index, and each Session ID is ensured to have only one video URL in the current latest state to be effective, that is, even if the original Session ID is stolen, batch-level user-scale resource reuse cannot be performed, so that the operation, server, bandwidth and storage costs of the scheduling server are effectively reduced, and the current memory of the scheduling server has only one video URL in the latest state to be effective, so that the possibility of stealing links can be stably and reliably avoided.
