信息保密与信息隐藏：将敏感信息或文件隐藏在一副图像、一段音乐或视频中，起到信息保密的作用。输入密码，还可从含密图像、音乐或视频中完整提取出原始敏感信息或文件。这种信息保密方法与传统加密方法不同，可使秘密信息或文件“彻底消失”，从而察觉不到秘密信息的存在性。
版权保护、防伪溯源与数字水印：一些正规商家辛辛苦苦拍摄的商品图片和视频，却被山寨店铺轻松利用并进行宣传，这不仅会对图像和视频的原创者带来损失，也会对消费者误导。非授权、AI生成或篡改的非法图片和视频在社交网络传播和扩散，会对个人和社会造成不良影响，破坏正常的社会秩序，因此需要追究其责任。解决这些问题的一种重要技术就是在图片和视频中添加鲁棒水印进行版权保护和溯源，且不影响其视觉质量和使用价值。
人工智能（AI）与数字取证：眼见一定为实、耳听一定为真吗？答案是“No！”。大模型时代的到来，使得图像、音视频等多媒体信息的生成、编辑和篡改愈发容易，因此伪造或AIGC图片、声音、视频难以辨认。通过结合机器学习、深度学习、大模型等人工智能方法，可实现对质疑的多媒体信息鉴别真伪，以AI攻AI，使AI向善向美。
鲁棒哈希与生物认证：防欺骗性高的身份信息可以是生物指纹、声纹、人脸等生物特征，这些生物特征具有一定的感知冗余。感知哈希具有鲁棒性、抗碰撞性、紧凑性和安全性等特点，通过生成这些生物特征的鲁棒哈希，可达到基于生物特征身份认证的目的。
