Thank you for your reply @guruvaj.
First government law enforcement agencies, their cybercrime department should already conduct research and countertechnology to detect deepfake images and videos.
They already do so. US recently started an intense research on deepfake in order to prevent abuses in the upcoming elections.
Security and privacy should be thoroughly practiced by each individuals in the nearest future.
I 100% agree. Awareness of the threat must definitely grow.
Government policies, rules and regulation of companies and organization should also be kept abreast with new threats like these on their people and as an entity as a whole.
Unfortunately governments seem to be rather afraid of technology thus focusing on completely eliminating it rather than educating people.
