Patent ID: 8737620

Claim:
A system for securely providing a secret data to one or more receivers, wherein the receiver comprises a first memory configured for storing a sequence of functions originating from a hierarchy of functions, for migrating the secret data from an input transform space to a final output transform space, the system comprising: a sender including: an interface for communication with one or more receivers; a processor configured to: define the hierarchy of functions such that the sequence of the functions comprises: a first function at a first level of the hierarchy of functions, for transformation of the secret data using a first seed, a second function at a second level of the hierarchy of functions, for transformation of the output of the first function using a second seed, and a third function at a third level of the hierarchy of functions for transformation of the output of the second function using a third seed; provide either one or more of the seeds including the second seed to the receiver; and change accessibility of the receiver to the secret data by updating the second seed based on the third seed of the receiver, wherein a transformation is a particular data encoding chosen to be lossless and not easily reversible.
