Authentication using stored biometric data

A computing device configured to process a biometric template retrieved from a smart card, said computing device comprising:

• a memory configured to store instructions;
• and
• a processor configured to execute said instructions to:
• encrypt said biometric template using a content protection key to form an encrypted biometric template;
• encrypt said content protection key to form an encrypted content protection key;
• and
• store, in a cache, said encrypted biometric template and said encrypted content protection key.

A computer-readable medium containing computer-executable instructions that, when performed by a processor for processing a biometric template retrieved from a smart card, cause said processor to:

• retrieve said biometric template from said smart card using a smart card reader;
• encrypt said biometric template using a content protection key to form an encrypted biometric template;
• encrypt said content protection key to form an encrypted content protection key;
• and
• store, in a cache, said encrypted biometric template and said encrypted content protection key.

A method for authenticating a user in order to provide said user with access to a user computing device, said method comprising:

• obtaining at least one of a device password or a smart card password from said user;
• obtaining a biometric scan from said user;
• retrieving, from a cache, an encrypted biometric template and an encrypted content protection key;
• verifying said at least one of said device password or said smart card password;
• decrypting said encrypted content protection key to form a decrypted content protection key;
• using said decrypted content protection key to decrypt said encrypted biometric template to form a decrypted biometric template;
• comparing said biometric scan with said decrypted biometric template;
• and
• if said biometric scan matches said decrypted biometric template, providing said user with access to said user computing device.
