In addition, "first", "second" are used to distinguish different objects, not to describe a specific order.

[0029] Please refer to Figure 1The embodiment of the application provides a structural schematic diagram of a virtual anchor management system, which comprises:

[0030] The virtual anchor registration module 110 is used for receiving identity information, a virtual anchor model file and copyright ownership proof submitted by a copyright party.

[0031] The copyright party can be a developer, a designer or a purchaser of the virtual anchor, namely a designer of the model appearance, a developer of the model or a purchaser of the model, and the copyright owner can be a company or an individual, which is not specifically limited herein.

[0032] The identity information provided by the copyright party can be an ID card or a business license of an enterprise, the model file can be a picture, a three-dimensional model, an animation video or a design original drawing, and the copyright ownership proof can be a copyright registration certificate or other proof documents.

[0033] The data information submitted by the copyright party can be submitted in the form of a data file or a picture and uploaded on the system.

[0034] The audit module 120 is used for auditing the identity information, the model file and the copyright ownership proof submitted by the copyright party.

[0035] The data material information provided by the copyright party can be automatically audited by the system, manually audited or automatically audited by the system in combination with manual auditing, and the specific method is determined according to actual conditions.

[0036] The identity authentication module 130 is used for generating a pair of public and private keys by using a predetermined public key encryption algorithm after the information submitted by the copyright party is audited, the private key is used for digitally signing the virtual anchor, and the public key is used for authorizing the third-party user to use the virtual anchor.

[0037] After the virtual anchor model related material information submitted by the copyright party is audited, the third-party user needs to be authorized and authenticated by using an encryption algorithm. The public key encryption algorithm, namely the asymmetric encryption algorithm, is an encryption method composed of a pair of unique keys (namely a public key and a private key).

[0038] Preferably, the predetermined public key encryption algorithm is an RSA algorithm or an SM2 algorithm.

[0039] When the third-party user is authorized, the public key can be provided to the third-party user, and the private key is used for digitally signing the current virtual anchor model.

[0040] The feature collection module 140 is used for collecting multi-dimensional features of the virtual anchor model, generating a feature vector and binding the feature vector with the digital signature of the virtual anchor.

[0041] The virtual anchor model file is parsed, and feature data contained in the model file is collected. The multi-dimensional features can include panel and expression features, hairstyle features, clothing features, hand movement features, limb movement features, and voiceprint features. The features that need to be protected or authenticated in the multi-dimensional features are sampled.

[0042] Specifically, the multi-dimensional feature collection of the virtual anchor model includes:

[0043] By the first feature collection function, the facial region identifier, the facial feature contour shape, and the position identifier in the virtual anchor model file are collected and saved as the first feature value;

[0044] By the second feature collection function, the hair region identifier, the hairstyle contour, and the position identifier in the virtual anchor model file are collected and saved as the second feature value;

[0045] By the third feature collection function, the ornament region identifier, the contour shape, and the position identifier in the virtual anchor model file are collected and saved as the third feature value;

[0046] By the fourth feature collection function, the hand region identifier, the hand shape contour shape, and the position identifier in the virtual anchor model file are collected, the hand gesture or action trajectory is identified, and the fourth feature value is saved;

[0047] By the fifth feature collection function, the trunk and limb region identifier, the contour shape, and the position identifier in the virtual anchor model file are collected, the limb movement trajectory is identified, and the fifth feature value is saved;

[0048] By the sixth feature collection function, the voiceprint feature of the audio in the virtual anchor model file is collected and saved as the sixth feature value.

[0049] The system generates a feature vector according to the collected multi-dimensional feature values. For example, the facial feature value is p1, the hairstyle feature value is p2, the clothing feature value is p3, the hand movement feature value is p4, the limb movement feature value is p5, and the voiceprint feature value is p6. The virtual anchor feature vector can be represented as A={p1, p2, p3, p4, p5, p6}. The feature vector A can select part or all of the feature values to represent.

[0050] Preferably, part or all of the feature values are selected as a group of feature vectors, and at least two different feature vectors are saved. The same virtual anchor can save multiple feature vectors for sampling, and the complete image of the virtual anchor can be more comprehensively defined based on multiple feature vector groups.

[0051] The above feature vector is bound to the digital signature of the virtual anchor. The digital signature can effectively prove the features of the virtual anchor, ensure the completeness and validity of the feature data, and prevent tampering.

[0052] The authorization management module 150 is configured to set an authorization white list of legal users, and the white list includes a domain name or an IP list of a legal virtual anchor user;

[0053] The legal user is a virtual anchor user authorized by a copyright party, and the white list is used to record the legal user who has been authorized, and the legal user is mainly identified by a domain name or an IP list of the user.

[0054] The authentication module 160 is configured to verify whether the virtual anchor and the user are authorized by loading an SDK for feature analysis and digital signature identification.

[0055] For an unknown virtual anchor user, it is necessary to authenticate and identify whether the virtual anchor user is authorized, that is, to verify the identity of the virtual anchor and whether the virtual anchor and the user have a belonging or authorized relationship.

[0056] In one embodiment, as shown in Figure 2 The authentication module 160 includes:

[0057] The public key import unit is configured to import a public key generated by the identity authentication module when a virtual anchor with a bound digital signature is used by a copyright party or a third party.

[0058] The verification unit is configured to verify whether the virtual anchor and the user are authorized by loading an SDK for feature analysis and digital signature identification.

[0059] The prompt unit is configured to inform the live broadcast platform and the user that the current virtual anchor model cannot be loaded for live broadcast when it is verified that the virtual anchor model is not authorized.

[0060] When a virtual anchor model with a bound digital signature is used, a public key is imported. The live broadcast software performs signature verification by loading an SDK (Software Development Kit) for feature analysis and digital signature identification, judges the identity of the virtual anchor and the relationship between the virtual anchor and the user, and informs the live broadcast platform and the user that the virtual anchor is not authorized and cannot be used when the signature verification fails.

[0061] The feature analysis module and the digital signature identification module can be defined in advance. The feature analysis module is used to extract and analyze the features of the virtual anchor, and judge whether the features are similar to the virtual anchor features saved in the system. The digital signature identification module is used to judge whether the digital signature of the current virtual anchor can be identified. The SDK is constructed based on the feature analysis module and the digital signature identification module, and can be imported by the system authentication module.

[0062] The theft management module 170 is used for actively searching live broadcast, recording and publicity data of a virtual anchor related live broadcast platform, acquiring and judging whether the virtual anchor is registered and whether the user of the virtual anchor is authorized, and if the virtual anchor is registered and not authorized, saving the collected data and informing the copyright party.

[0063] The virtual anchor related live broadcast, recording and publicity data of each live broadcast platform are actively acquired, the virtual anchor related feature data are extracted, and then it is judged whether the virtual anchor is registered in the system and whether the user of the virtual anchor is authorized. If not authorized, the collected data can be saved and the copyright party is informed. Thus, the possible infringement behavior of the copyright party can be timely reminded, and the evidence can be collected and saved.

[0064] In the embodiment, after the virtual anchor model of the copyright party is uploaded, the anchor model is authenticated, the legal user is authorized, the unknown virtual anchor model and user are authenticated and judged, and the unauthorized users found by searching are warned and prompted, so that the virtual anchor is effectively managed, the similar virtual anchor is accurately judged, and the theft behavior is efficiently warned.

[0065] It should be understood that the sequence numbers in the above embodiments do not mean the order of execution, and the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
