Method of encryption and decryption and a keyboard apparatus integrated with functions of memory card reader and fingerprint encryption/decryption

摘要

A method of encryption and decryption and a keyboard apparatus integrated with a memory card reader and an encryption/decryption scheme using fingerprints is disclosed. The invention integrates a memory card reader and a fingerprint scan module into a keyboard apparatus. The memory card reader and fingerprint scan module are jointly using the power supply and data transmission port. Therefore, the keyboard apparatus uses the memory card reader to function data transferring, and the fingerprint scan module is used to retrieve a fingerprint of the user, which is used to encrypt or decrypt the data in the memory card by the keyboard's driver. Thereby, in the preferred embodiment, the biometric characteristic is applied to encrypt/decrypt the data in the computer system or the data in the memory card by a program installed in the computer system. The multi-functional keyboard is achieved.
