Microsoft announced the upgrade of the ai function Recall, which was released in May and then recalled, and has started designing multiple layers of security measures for Recall to prevent hackers. In the upcoming new version of Recall, sensitive data is encrypted with a golden key and isolated on the user's computer, so even if the computer is infected with malware or stolen, intruders cannot access it. Decryption of data requires biometric matching. The modified product will be provided to consumers next month in the form of a test version. Recall only works on Copilot+ PC's new Windows 11 computers. The upgraded version of Recall will not be automatically installed on commercial versions of computers. Recall can record everything users do on their computers. Microsoft received significant negative feedback when Recall was launched in May, with users concerned about data theft and the collection of records stored on the computer.
