Abstract
A computing device includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to determine a secret to be protected. The at least one processor is also configured to split the secret into a plurality of secret shares, at least a subset of which are required to reconstitute the secret. The at least one processor is also configured to transfer each secret share to a respective portable storage device or media for distribution to a respective shareholder. The at least one processor is also configured to generate metadata with at least a hash of each secret share, wherein the metadata is stored separate from the portable storage devices or media with the secret shares.
