Future JPEGs Could Use Blockchain to Flag Fakes
Imagine if every JPEG image file had blockchain-protected data that would verify 8212; or refute 8212; a photograph’s origins. The concept may be more than just an idea. The same organization that created the JPEG wants to use blockchain to flag fake news and fight image theft.
But, what JPEG wants to do is create a standardized system that uses encryption, hash signatures, watermarking or a combination inside a photograph’s metadata. The JPEG format is widely used, building a standardized system, in the same way, could create a widely-used system that anyone could access without signing up for a program. By creating a standard, any application could use the metadata built into the photo to protect images 8212; perhaps, with such a standard, social media networks could even analyze the image’s metadata and recognize faked photos at upload.
The key word, though, is 8220;could 8221; 8212; currently, the committee is just in the discussion phases and is speaking with industry leaders to determine what such a system could be used for and what should be part of the standardization. The group has stated, however, that they’ve identified 「great potential」 in the technology. The group has been running workshops on the topic since 2018, but held an open discussion at their latest meeting.
Besides identifying fake news and flagging copyright violations, JPEG suggests that such a system could be used for media forensics, along with applications in privacy and security. The latest discussion also suggested the possibility of using the technology for smart contracts.
8220;The efforts to find new and improved solutions in image compression have led JPEG to explore new opportunities relying on machine learning for coding,」 professor Touradj Ebrahimi, the convenor of the JPEG Committee, said in a statement. 8220;After rigorous analysis in form of explorations during the last 12 months, JPEG believes that it is time to formally initiate a standardization process, and consequently, has issued a call for evidence for image compression based on machine learning. 8221;标签：
