孪生数字人的形象与语言授权框架研究

A Study on the Image and Language Empowerment Framework of Twin Digital People

由于AIGC(人工智能生成的内容)发展迅速,网络上涌现出一大批生成视频,但生成式AI可能会产生许多虚假信息,会对公众造成严重误导,不法之徒可以利用低成本高效率伪造文本、图片甚至视频进行诈骗、恐吓、诽谤等行为。据此,提出一个可以对孪生数字人的语言和行为进行授权的框架,该框架通过人脸识别和区块链加密生成数字签名,最后生成数字证书对信息进行保存授权。该方法有效地对生成的孪生数字人视频进行了真人核对、信息验证和物理信息保存授权。经过实验验证,该框架完全可以通过对视频内容的检测,达到对具体时空切片内所发布的言论和行为进行授权和鉴别的要求。

Due to the rapid development of AIGC(artificial intelligence generated content),a large number of generated videos have emerged on the web,but generative AI may generate a lot of false information,which could be seriously misleading to the public,and unscrupulous people could use the low cost and efficiency to fake texts,images,or even videos to commit fraud,intimidation,defamation,etc.A frame-work for authorising the language and behaviour of twin digital humans is proposed.The framework generates digital signatures by combining face recognition and encryption in the blockchain,and finally generates digital certificates to store the information for authorisation.The meth-od effectively generates a video of the twin digital person for real person verification,message validation and physical information retention au-thorisation.It has been experimentally verified that the framework is fully capable of achieving authorisation and identification of the state-ments and actions posted within specific slices of time and space through content detection of the videos.
