摘要： For the purpose of data encryption a reference data vector is acquired from a reference object. The reference object can be a physical object such as a passport, a biometric feature, or a rendered data object. A set of random vectors for each bit to be encoded is determined on the basis of the reference data vector. For the purpose of decryption the reference data vector is acquired again.
