Vision Transformer-Based Video Hashing Retrieval for Tracing the Source of Fake Videos

Algorithm 1

The whole calculation process of the hash triplet loss.

(1)	ViTHash outputted hashes and related labels as ;
(2)	Voted hash centers and related labels as loss of hash triplet loss
(3)	Calculate the intraloss between the triplet samples and the voted hash center;
(4)	Def IntraLoss(,):
(5)	return ;
(6)	;
(7)	Calculate the interloss between the triplet samples with the other hash centers;
(8)	Def InterLoss(,):
(9)	return ;
(10)	;
(11)	Calculate the hash triplet loss;
(12)	Function Main :
