A request to access the sensitive data will specify user credentials for the access. The submitter is requested to confirm a security identifier for the requested access. An incorrect security identifier will be presented for incorrect credentials, which will be easy for a user to identify but not for an attacker or other unauthorized user. If the incorrect security identifier is confirmed, the device assumes the request was received from an unauthorized source. The sensitive data is stored under format-preserving cryptography, such that false data values can be generated that have the correct format. An unauthorized user receiving the false data will not be readily able to determine the data received is incorrect, and will be likely to discontinue the attack, particularly for an automated process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Feedback-based data security","description":"Encryption of sensitive data on consumer devices is provided with format-preserving cryptography and feedback via the use of security identifiers.
