Abstract
This paper discusses a novel approach to detect inter frame and intra frame video forgery using content based signature. A novel technique called the “Spatio Temporal Triad Feature Relationship” (STTFR) is employed to generate a unique content based signature – value for any given video sequence. The proposed STTFR algorithm aims to verify video integrity through the creation of a 128 bit message digest from the input video of variable length that will be unique to that video and acts as a fingerprint. Change in the video sequence, either at the spatial or at the temporal level will result in a different fingerprint than the one obtained originally. The knowledge of the signature will not enable any person/entity to recreate the original video as the signature is generated by combining spatial and temporal fingerprints in an orderly and systematic approach. We have verified our technique with standard datasets and found accurate results.
