Abstract
A method and apparatus for improved data management are described. In one embodiment, the method comprises generating a first key component, generating an encryption key using the first key component, a token key and a personal identification number (PIN), encrypting data using the encryption key, and sending the data encrypted with the encryption key to a server along with the first key component.
Claims26
A method comprising:
- generating a first key component;
- generating an encryption key using the first key component, a token key and a personal identification number (PIN);
- encrypting data using the encryption key;
- sending the data encrypted with the encryption key to a server along with the first key component.
1 more element
A method comprising:
- encrypting data using the encryption key generating using a first key component, a token key and a personal identification number (PIN);
- storing data encrypted using the encryption key;
- and
- regenerating the encryption key after accessing the encrypted data to decrypt the encrypted data therewith.
1 more element
A method comprising:
- retrieving a key component and encrypted data from a server;
- recreating an encryption key using the key component, a token key and a personal identification number (PIN);
- and
- performing a decryption operation on the encrypted data using a decryption key based on the encryption key used to encrypt the encrypted data.
1 more element
A method for authentication comprising:
- generating authentication data for a user based on a token key and a personal identification number (PIN), the token key being unique to the user;
- and
- receiving a confirmation indicating that the authentication data has been verified.
A method comprising:
- accessing encrypted data from a server;
- decrypting the encrypted data using a token and a user-specific PIN to be accessed.
