Authentication of an Image with Sha-1 and Invariant Vector Distances
2019
VOLUME-8 ISSUE-10, AUGUST 2019, REGULAR ISSUE
Preserved Fulltext
The SHA-1 algorithm, invariant vector distance and ring division are implemented to authenticate the image by using hash value to enhance discriminative capability and rotation robustness. ...
Specifically, the digital operations of an image are not changed with respect to Euclidean distance and feature vectors. This makes message digest discriminative and dense. ...
