Apple introduces Apple Reference Image on iPhone 18 Pro. In Reference mode, the camera sensor cryptographically signs each pixel captured, then Apple secure servers generate an unalterable reference image stored beside the editable photo. Apple says the design makes pixel tampering impractical without costly physical attacks, offering stronger protection against AI-fake imagery than detector-based approaches.

ABOUT

What is Fimmer?

Most feeds treat all company headlines the same. An executive interview, an office closure, stock analysis, and a data breach can sit side by side with no sense of scale. Fimmer ranks coverage by what matters, so important events stand out and signals are prioritised over noise. We cluster related company news and score each story using a range of metrics, so you see the most crucial stories first.

SCORING

What do the scores mean?

Significance (0–10) measures the scale of the real-world impact. Sentiment and ESG (−10 to +10) indicate the tone of the coverage and whether the change relates to environmental, social, or governance factors. Together, these scores help distinguish meaningful developments from routine company news. More information about our scoring methodology can be found on our About page.
