Buried in all the talk of password salting, the interesting thing I see about "blind hashing" is that the blind hashing service can be viewed as a new hash function with some interesting properties: - Implementing the hash function requires petabytes of storage - Pre-image, second pre-image, and collision resistance depend on the quality of the random data block that defines the function - Pre-image and second pre-image resistance depend on the function being kept secret - The function is hard to steal because it is petabytes massive - If the function were stolen, a pre-image attack would be a matter of searching petabytes of data
