ELECTRONIC DEVICE FOR ENCRYPTING BIOMETRIC DATA AND OPERATION METHOD OF ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18448972 titled 'ELECTRONIC DEVICE FOR ENCRYPTING BIOMETRIC DATA AND OPERATION METHOD OF ELECTRONIC DEVICE
Simplified Explanation
- The patent application describes an electronic device that includes a biometric sensor for acquiring biometric data. - The device has a processor with a general region and a trusted region, where a trusted application with a designated security level or higher is executed in the trusted region. - The device also includes a memory for storing encryption information related to registered biometric data. - There is a security processor physically separated from the main processor, which is responsible for encrypting the biometric data acquired by the sensor. - The main processor loads the encrypted biometric data onto the trusted region and extracts feature information for biometric authentication from the encrypted data. - The feature information is then compared with the encryption information stored in the memory. - Based on the result of the comparison, the device performs biometric authentication.
Original Abstract Submitted
An electronic device includes: a biometric sensor for acquiring biometric data; a processor including a general region, and a trusted region which is distinguished from the general region and in which a trusted application having a designated security level or higher is executed; a memory for storing encryption information (encryption data) related to registered biometric data; and a security processor which is physically separated from the processor, where the security processor is configured to encrypt the biometric data acquired by the sensor, and the processor is configured to: load the encrypted biometric data onto the trusted region, the biometric data being acquired from the security processor; extract feature information for biometric authentication from the encrypted biometric data; compare the feature information with the encryption information acquired from the memory; and perform the biometric authentication on the basis of a result of the comparison.
