Method and apparatus for encrypting/decrypting data

摘要

A method of encrypting data using a first key and multiple encryption keys at least in part based on the first key. The method includes encoding the data into a redundant representation by distributing the information content of the data among a number of groups, each group being associated with a respective encryption key of the multiple encryption keys, each encryption key being associated with at least one group, the redundant representation allowing recovery of the data in the absence of the groups associated with the at least one of the multiple encryption keys, and encrypting each group by the respective associated encryption key.

1. A method of encrypting data comprising:
communicating, by at least one processor, with a biometric device configured to collect a noisy source of data; obtaining, by the at least one processor, a noisy source of key information based at least partially on the noisy source of data; generating, by the at least one processor, a first key based at least partially on the noisy source of key information; distributing, by the at least one processor, unique segments of the noisy source of key information across multiple encryption keys such that at least one of the multiple encryption keys include a segment that is not present in other encryption keys of the multiple encryption keys;
encoding, by the at least one processor, the data by distributing the data redundantly among a number of groups, each group being associated with a respective encryption key of the multiple encryption keys; andencrypting, by the at least one processor, each group by the respective associated encryption key.
