Computer security applications use cryptography keys, cryptography codes—such as one-time passcodes—and other user credentials to protect the secrecy, authenticity and integrity of applications such as financial information, financial transactions and infrastructure (e.g. the electrical grid, power plants, and defense systems). The prior art attempted to generate (e.g. derive) an invariant from a biometric template, biometric print or non-biometric pattern that is used as a security key or code. Biometric variability has been a difficult obstacle for the prior art. In an embodiment, the invariant is at least partially generated (e.g., derived) a transformation between the biometric templates or prints. In an embodiment, the invariant is a cryptography key. In an embodiment, the transformation(s) help perform an authentication of the user and are executed by digital computer program instructions. In an embodiment, pattern transformation(s) are represented with colors, geometry or frequencies.
