According to foreign media Neowin,A copy released last weekwhite paperAdobe announced plans to launch a feature designed to curb the spread of fake / modified ("photoshopped") photos online.Adobe launched the content authenticity Initiative (CAI) a year ago with the help of the New York Times and twitter.
Under the plan, Adobe's goal is to use a tagging system to trace an image back to the photographer and the location where the photo was taken. These tags will have an additional layer of security with the help of encrypted signatures. Whenever a photo is edited, subsequent tags are added to create a record that contains the full history and origin of the photo to verify its integrity. Adobe believes that the binding of these metadata with photos will help ease the spread of false information and fake photos on the Internet.
Cai's move comes at a time when false information is in vogue, and social media giants have taken a firm attitude to crack down on false information. Twitter has repeatedly tagged US President Trump's tweets with factual errors. Facebook has also attracted attention for its stance on false information. It will be interesting to see if such sites implement the back-end services for the proposed metadata architecture.
Adobe realizes that the effectiveness of this system depends on its adoption. According to wired, the earliest use of the system in journalism may have come from the New York Times. However, camera manufacturers, content creators, software companies, publishers and social media platforms all need to support the standards proposed by CAI in order to be effective. A committee of trusted authorities to manage and control digital certificates for metadata also seems necessary.
