A second embodiment of the invention relates to a method of authenticating an access request. The second embodiment is improved on the basis of the first embodiment, and the main improvement lies in that: in a second embodiment of the invention, a specific authentication algorithm for the authentication request is provided.
Fig. 2 shows an authentication method for an access request in this embodiment, steps 201 and 203 are the same as steps 101 and 103 in the first embodiment, and are not described herein again, and step 202 in this embodiment includes the following sub-steps:
the substep 2021 obtains a feature parameter corresponding to the URL corresponding to the resource to be accessed from the preset starting time to the current time.
In this embodiment, the authentication request includes a URL corresponding to the resource to be accessed.
And a substep 2022 of matching the characteristic parameters with preset parameters and generating a matching result.
In this embodiment, the preset parameter corresponds to a preset starting time to a preset ending time. The preset parameters may be pre-configured in the authentication server (however, the configuration manner of the preset parameters is not limited at all). In addition, the matching result includes matching and not matching.
In an example, the preset starting time is, for example, 00.00 per day, and the preset ending time may be 24.00 per day, but in practice, the preset starting time is not limited thereto, and the time length between the preset starting time and the preset ending time and the specific time are not limited in any way in this embodiment.
In one example, the preset start time is 18.00 points, the preset stop time is 23.00 points, and the preset parameters are parameters corresponding to 18.00 points to 23.00 points.
In this embodiment, the authentication result of the legal request is generated according to the matching result, and the authentication result of the non-legal request is generated according to the unmatching matching result.
Compared with the prior art, the embodiment provides a specific authentication algorithm for the authentication request; the method comprises the steps of acquiring characteristic parameters corresponding to a URL corresponding to a resource to be accessed from a preset starting moment to a current moment, matching the characteristic parameters with the preset parameters to generate a matching result as the characteristic parameters are real-time effective characteristic parameters of the URL, and generating an authentication result according to the matching result, so that the URL of the stealing link resource can be found in real time, the possible risk of stealing link is avoided, and the accuracy of the authentication result is further improved.
The third embodiment of the present invention relates to an authentication method of an access request, which is improved on the basis of the second embodiment, and the main improvement is that: in the third embodiment of the present invention, when the request mode identifier requesting the resource to be accessed is the fragmentation request identifier or the segmentation request identifier, the feature parameter corresponding to the URL carried in the authentication request is the number of the user terminals accessing the URL.
Fig. 3 shows an authentication method for an access request in this embodiment, steps 301 and 303 are the same as steps 201 and 203 in the second embodiment, and are not described herein again, and step 302 in this embodiment includes the following sub-steps:
and a substep 3021, acquiring the number of the user terminals accessing the URL corresponding to the resource to be accessed from the preset starting time to the current time.
In one example, the user terminal may be represented by an IP address of the user terminal, that is, the number of IPs of the user terminal accessing the URL from a preset starting time to a current time is obtained; however, this embodiment is only an exemplary illustration, and the present embodiment does not set any limitation on the manner of counting the number of user terminals accessing the URL.
In this embodiment, the authentication request carries a request mode identifier for requesting the resource to be accessed, a URL corresponding to the resource to be accessed, and an IP address of the user terminal, and determines that the request mode identifier is a fragment request identifier or a segment request identifier.
In this embodiment, the number of IPs accessing the URL in the preset period may be periodically obtained, for example, once every 5 minutes, but in practice, the present embodiment is not limited to this, and for example, the number may also be obtained in real time.
In this embodiment, the authentication server receives an authentication request including a URL indicating that the URL is accessed by the user terminal; in one example, the authentication server is preset to record the number of IPs of the user terminal accessing each URL from a preset start time to the current time (if a certain URL is accessed by the same terminal for multiple times, the IP of the user terminal is recorded as one), so as to directly obtain the number of IPs of the URL from the recorded preset start time to the current time; however, this embodiment is only an exemplary illustration, and the present embodiment does not limit the manner of acquiring the IP number.
Sub-step 3022, matching the number of user terminals accessing the URL with a first preset number and generating a matching result.
In this embodiment, the preset parameter is a first preset number; the first preset number may be, for example, 6, but in practice, the present embodiment is not limited to this, and the specific numerical value of the first preset number is not limited at all, for example, the first preset number may be set in consideration of a situation that the users in the region use the network of the small operator (a situation that the network of the small operator has multiple outlets IP), and if there are more users using the network of the small operator, the numerical value of the first preset number may be set to be higher.
In one example, the first preset number is carried by a URL corresponding to the resource to be accessed, that is, the URL dynamically carries the first preset number; for example, if the extracted URL dynamically carries a first preset number of 8, it indicates that the URL is only allowed to be accessed by 8 user terminals, but in practice, the URL is not limited thereto, and this embodiment does not limit this.
In this embodiment, the number of the user terminals may be used as the number of the user terminals, and the obtained number of the user terminals may be compared with the first preset number; when the number of the IPs is smaller than or equal to a first preset number, generating a matching result; when the number of the IPs exceeds a first preset number, generating a mismatching result; however, the present invention is not limited thereto, and the present embodiment does not limit the present invention.
And a substep 3023, if the number of the matching results exceeds the first preset number and it is determined that the ue triggering the authentication request does not belong to the ues in the first preset number, generating an authentication result of the unauthorized request.
In this embodiment, if the number of the matching results exceeds the first preset number and it is determined that the ue triggering the authentication request does not belong to the ues in the first preset number, it indicates that the ue triggering the authentication request accesses the resource to be accessed for the first time from the preset starting time to the current time, and the ue accesses the URL after the first preset number, and then generates the authentication result of the unauthorized request.
In one example, the number of IPs of the user terminals that acquire the URL corresponding to the access video a from the preset start time to the current time is 8 (the user terminal that triggers the authentication request of this time is the 8 th terminal that accesses the URL), the 8 user terminals that access the URL are terminals C1, C2, C5, C7, C11, C15, C9, and C14, respectively, and the first preset number is 7; obviously, if the number of the 8 user terminals exceeds 7, and C14 is not one of the first 7 user terminals, an authentication result of the non-legal request is generated; however, this is merely an example and is not limited thereto.
And a substep 3024, generating an authentication result of the valid request if the number of the matching results does not exceed the first preset number.
In this embodiment, if the number of the matching results does not exceed the first preset number and it is determined that the user terminal triggering the authentication request belongs to the user terminals in the first preset number, it is indicated that the user terminal triggering the authentication request has previously accessed the URL and the access sequence number of the terminal is less than or equal to the first preset number, and the authentication result of the legal request is generated.
In one example, the number of IPs of the user terminals that acquire the URL corresponding to the access video a from the preset start time to the current time is 8 (the user terminal that triggers the authentication request of this time is the 8 th terminal that accesses the URL), the 8 user terminals that access the URL are terminals C1, C2, C5, C7, C11, C15, C9, and C5, respectively, and the first preset number is 7; obviously, if the number of 8 exceeds 7 and C5 is one of the first 7 ues, the authentication result of the legal request is generated; however, this is merely an example and is not limited thereto.
Compared with the first implementation mode, the embodiment of the invention has the advantages that when the request mode identifier is the fragmentation request identifier or the segmentation request identifier, the characteristic parameters corresponding to the URL carried by the authentication request are the number of the user terminals accessing the URL, namely, the forbidden object of the embodiment is the user terminal (if a hotlink is found, the user terminal is forbidden), and the request mode identifier carried by the authentication request is matched with a specific authentication algorithm, so that the flexibility and the efficiency are high, and the diversified authentication requirements of customers are met.
A fourth embodiment of the invention relates to a method of authenticating an access request. The fourth embodiment is improved on the basis of the second embodiment, and the main improvement lies in that: in the fourth embodiment of the present invention, when the request type identifier is a request for loading a complete resource identifier, the characteristic parameter corresponding to the URL carried in the authentication request is the number of times the URL is accessed.
Fig. 4 shows an authentication method for an access request in this embodiment, steps 401 and 403 are the same as steps 201 and 203 in the first embodiment, and are not described herein again, and step 402 in this embodiment includes the following sub-steps:
in sub-step 4021, the number of times of access to the URL corresponding to the resource to be accessed from the preset start time to the current time is obtained.
In this embodiment, the authentication request carries a request mode identifier for requesting a resource to be accessed and a URL corresponding to the resource to be accessed, and the request mode identifier is a one-time request complete resource identifier.
In this embodiment, the number of times that the URL is accessed in the preset period may be periodically obtained, for example, obtained every 5 minutes, but is not limited to this, and for example, the URL may also be obtained in real time in this embodiment.
In this embodiment, the authentication server receives an authentication request including the URL, indicating that the URL is accessed by the user terminal; moreover, the URL may be accessed by the same user terminal for multiple times, or may be accessed by different user terminals. In one example, the authentication server may be preset to record and store the number of times of access to the URL included in the authentication request received from the preset start time to the current time, so as to directly obtain the number of times of access to the URL from the preset start time to the current time; however, this embodiment is only an exemplary illustration, and the present embodiment does not set any limitation on the manner in which the URL is accessed.
And a sub-step 4022 of matching the accessed times with the first preset times and generating a matching result.
In this embodiment, the preset parameter is a first preset number of times; the first preset number of times may be 5 times or 10 times, and an appropriate value may be set in consideration of a scene where the authentication request is abnormally disconnected.
In one example, the first preset times are carried by the URL corresponding to the resource to be accessed, that is, the URL dynamically carries the first preset times, so that various authentication requirements are met, and the first preset times are directly obtained from the URL (configuration work on the authentication server is saved), so that the authentication speed is increased; for example, if the extracted URL dynamically carries the first preset number of times of 10, it indicates that the URL is only allowed to be accessed 10 times, but in practice, the present embodiment is not limited thereto.
In an example, the obtained number of accesses may be compared with a first preset number, if the number of accesses exceeds the first preset number, a non-matching result is generated, and if the number of accesses is less than or equal to the first preset number, a matching result is generated, which is only an exemplary illustration, and the specific generation manner of the matching result is not limited in this embodiment.
In the sub-step 4023, if the matching result is that the number of times of access exceeds a first preset number of times, an authentication result of the non-legal request is generated.
In the sub-step 4024, if the matching result is that the number of times of access does not exceed the first preset number of times, an authentication result of the legal request is generated.
In a specific example, the preset starting time is 12.00 points, the preset ending time is 21.00 points, the current time is 15.00 points, and the first preset times corresponding to 12.00 to 21.00 are 12 times; the number of access times of the URL corresponding to the video A from 12.00 to 15.00 is 15, obviously, the number of access times exceeds the preset number of access times by 12, and an authentication result of a non-legal request is generated; however, this is merely an example and is not limited thereto.
Compared with the second embodiment, when the request mode identifier is a request for loading a complete resource identifier, the feature parameter corresponding to the URL carried in the authentication request is the number of times the URL is accessed, that is, the banned object in the embodiment is the URL (if a hotlink is found, the URL is prohibited from being accessed), and the request mode identifier carried in the authentication request is matched with a specific authentication algorithm, so that the method is flexible and efficient, and meets diversified authentication requirements of customers.
A fifth embodiment of the present invention relates to an authentication method for an access request. The fifth embodiment is improved on the basis of the second embodiment, and the main improvement lies in that: in the fifth embodiment of the present invention, when the request type identifier is a request for loading a complete resource identifier, the characteristic parameter corresponding to the URL carried in the authentication request is the number of times that the user terminal triggering the authentication request accesses the URL.

In this embodiment, the number of times that the user terminal accesses the URL from the preset start time to the current time may be periodically obtained, for example, obtained every 10 minutes, but in practice, the present embodiment is not limited to this, and for example, the present embodiment may also obtain the URL in real time.
In this embodiment, the authentication server receives the authentication request including the URL once, indicating that the URL is sequentially accessed by the user terminal; in one example, the authentication server may be preset, the user terminal is represented by an IP address of the user terminal, and the number of times that the IP of each user terminal accesses each URL from a preset start time to the current time is recorded and stored, so that the number of times that the user terminal accesses the URL from the preset start time to the current time is directly obtained; however, this embodiment is only an exemplary illustration, and the obtaining manner of the number of times that the user terminal accesses the URL is not limited in any way.
In this embodiment, the preset parameter is a second preset number of times; the second preset number may be 15 or 25, and the number of the second preset number is not limited in this embodiment.
In one example, the obtained times may be compared with a second preset time, and when the times exceed the second preset time, an unmatched matching result is generated; and when the times do not exceed the second preset times, generating a matching result. However, this embodiment is only an exemplary embodiment, and the specific determination method is not limited in any way.
In the substep 5023, if the number of the matching results exceeds the second preset number, the authentication result of the non-legal request is generated.
In the substep 5024, if the number of the matching results does not exceed the second preset number of times, an authentication result of the legal request is generated.
In one example, the preset starting time is 8.00 points, the preset ending time is 20.00 points, the current time is 17.00 points, and the second preset times corresponding to 8.00-20.00 are 8 times; the number of times of accessing the URL corresponding to the video A at the user terminal from 8.00 to 17.00 is 6, obviously the number of times of 6 does not exceed the second preset number of times of 8, and an authentication result of a legal request is generated; however, this is merely an example and is not limited thereto.
Compared with the second implementation mode, when the request mode identifier is a request for loading a complete resource identifier, the characteristic parameter corresponding to the URL carried by the authentication request is the number of times that the user terminal triggering the authentication request accesses the URL, that is, the forbidden object of the implementation mode is the user terminal (if a stealing link is found, the user terminal is forbidden), and the request mode identifier carried by the authentication request is matched with a specific authentication algorithm, so that the implementation mode is flexible and efficient, and meets the diversified authentication requirements of customers.
A sixth embodiment of the present invention relates to an authentication method of an access request. The sixth embodiment is an improvement on the second embodiment, and the main improvement lies in that: in the sixth embodiment of the present invention, when the file type of the resource to be accessed is the type of the FLV/MP4 requesting to load the complete resource once, the feature parameter corresponding to the URL of the resource to be accessed is the number of different URLs when the user terminal accesses the domain name corresponding to the URL.
Fig. 6 shows an authentication method for an access request in this embodiment, steps 601 and 603 are the same as steps 201 and 203 in the first embodiment, and are not described herein again, and step 602 in this embodiment includes the following sub-steps:

In this embodiment, the authentication request carries the file type of the resource to be accessed, the domain name and the URL corresponding to the resource to be accessed, and it is determined that the file type is the type of the FLV/MP4 that requests to load the complete resource once. In this embodiment, the preset period is, for example, 12 hours, and the specific duration of the preset period is not limited at all, and may be set according to an actual situation.
In this embodiment, the number of times of accessing the URL in the preset period may be periodically obtained, for example, obtained once every 10 minutes, but in practice, the present embodiment is not limited to this, and for example, the URL may also be obtained in real time.
In one example, the authentication server receives an authentication request, that is, it indicates that the user terminal (for example, the user terminal may be characterized by an IP address of the user terminal) accesses a domain name carried in the authentication request; the authentication server may count the number of different URLs of the domain name accessed by the user terminal in a preset period, so as to obtain the number of different URLs of the domain name accessed by the user terminal in the preset period.
And a substep 6022 of matching the number with a second preset number and generating a matching result.
In this embodiment, the preset parameter is a second preset number; the second preset number is, for example, 100, but in practice, the present embodiment is not limited thereto, and the specific value of the second preset number is not limited at all, and can be set according to the tolerance of the customer to the chain thief, so as to avoid the false prohibition of the normal user as much as possible.
In an example, the obtained number may be compared with a second preset number, and when the number of different URLs under the domain name corresponding to the URL exceeds the second preset number, an unmatched matching result is generated; when the number of different URLs under the domain name corresponding to the URL does not exceed a second preset number, generating a matching result; however, this embodiment is only an exemplary embodiment, and the specific determination method is not limited in any way.

And a substep 6024 of generating an authentication result of the legal request if the number of the matching results does not exceed the second preset number.
In one example, the predetermined period is 5 hours and the second predetermined number is 100; the number of different URLs of which the domain name is kanshi accessed by the user terminal within 5 hours in one preset period is 30, and obviously, 30 is smaller than the second preset number 100, so that the authentication result of the legal request is generated; however, this is merely an example and is not limited thereto.
In one example, the preset starting time is 15.00 points, the preset ending time is 22.00 points, the current time is 16.00 points, and the second preset number corresponding to 15.00 to 22.00 is 25 times; requesting a user terminal to access a video A under a domain name abc.com by the authentication request, wherein the number of different URLs under the domain name abc.com accessed by the user terminal is 13 from 15.00 to 16.00, and obviously, the number of the different URLs does not exceed 25 of a second preset number, so that an authentication result of a legal request is generated; however, this is merely an example and is not limited thereto.
Compared with the second embodiment, when the request mode identifier is a request for loading a complete resource identifier, the characteristic parameters corresponding to the URL of the resource to be accessed are the number of different URLs when the user terminal accesses the domain name corresponding to the URL, that is, the forbidden object of the embodiment is the user terminal (if a hotlink is found, the user terminal is forbidden), and the request mode identifier carried by the authentication request is matched with a specific authentication algorithm, so that the method is flexible and efficient, and meets the diversified authentication requirements of clients.
