<p>System and method for quorum-based data recovery, whereby a predetermined minimum number of versions of original data is received, and the original data is reconstructed from the received versions, wherein the original data cannot be reconstructed without loss unless a predetermined minimum number of versions is received. Preferably computed relationships such as equations that encode dependencies between data values of the original data the number of versions required. This computed relationship may be symbols of a codeword from an error correcting code or based on Galois field elements or complex numbers. Preferably the reconstructed data is an encryption or decryption key, an authentication key or a password.</p> |
