According to recent rumors on a Japanese news website, Sony's Xperia 1 VI and 5 VI will have "world first" features. This website has a history of being fairly accurate when it comes to reporting on Sony products. They claim that Sony is attempting to add digital signatures to images in order to discern if content has been tampered with.

Sony is well known for trying something new with every Xperia model they release. For example, the Xperia 1V has a pixel-stacked CMOS image sensor with two-layer transistors. The upcoming 1VI and 5VI may be no different. This would be consistent with Sony's recent announcement that a similar feature will be added to certain DSLR models via a software update. However, there is no update on whether this feature will be available on other Xperia phones.

Exact details on how this system will work are not known at this time. However, a recent Sony press release may have the answer as to how the in-camera digital signature chip works. This chip adds a digital signature to a photo as soon as it is taken. This allows the user to prove that the photo was taken with the camera. The signature also allows the user to know which parts of the image have been tampered with. Sony claims that this will increase transparency and trust in news sites.

The question is how useful this addition would be to the average user. The addition of digital signatures may make more sense in corporate and news situations. Also, there is no mention of integration with the app. If signatures could be verified on Instagram, this could be a big change, especially for filtered images. We will know more about how signatures will work once the next generation of Xperia phones are released. Sony's Xperia 1 VI is expected to debut in early 2024.
