信息保密與信息隱藏：將敏感信息或文件隱藏在一副圖像、一段音樂或視頻中，起到信息保密的作用。輸入密碼，還可從含密圖像、音樂或視頻中完整提取出原始敏感信息或文件。這種信息保密方法與傳統(tǒng)加密方法不同，可使秘密信息或文件“徹底消失”，從而察覺不到秘密信息的存在性。
版權(quán)保護、防偽溯源與數(shù)字水印：一些正規(guī)商家辛辛苦苦拍攝的商品圖片和視頻，卻被山寨店鋪輕松利用并進行宣傳，這不僅會對圖像和視頻的原創(chuàng)者帶來損失，也會對消費者誤導(dǎo)。非授權(quán)、AI生成或篡改的非法圖片和視頻在社交網(wǎng)絡(luò)傳播和擴散，會對個人和社會造成不良影響，破壞正常的社會秩序，因此需要追究其責(zé)任。解決這些問題的一種重要技術(shù)就是在圖片和視頻中添加魯棒水印進行版權(quán)保護和溯源，且不影響其視覺質(zhì)量和使用價值。
人工智能（AI）與數(shù)字取證：眼見一定為實、耳聽一定為真嗎？答案是“No！”。大模型時代的到來，使得圖像、音視頻等多媒體信息的生成、編輯和篡改愈發(fā)容易，因此偽造或AIGC圖片、聲音、視頻難以辨認。通過結(jié)合機器學(xué)習(xí)、深度學(xué)習(xí)、大模型等人工智能方法，可實現(xiàn)對質(zhì)疑的多媒體信息鑒別真?zhèn)?，以AI攻AI，使AI向善向美。
魯棒哈希與生物認證：防欺騙性高的身份信息可以是生物指紋、聲紋、人臉等生物特征，這些生物特征具有一定的感知冗余。感知哈希具有魯棒性、抗碰撞性、緊湊性和安全性等特點，通過生成這些生物特征的魯棒哈希，可達到基于生物特征身份認證的目的。
