Real-time encryption
Hanscan's products employ a complex algorithm that converts the captured biometric data into a series of encrypted numbers in real-time, or at the very moment of its collection. Biocryptology® is based on the principle that the conventional biometric information which is captured by a biometric device are being transformed into a set of numbers, which are constantly changing each time the biometric data are captured and processed. Neither original biometric images nor templates are being stored, only these sets of randomly changing numbers. Hanscan’s algorithm converts the registered biometric information as a series of encrypted numbers, not as an image or any other data form that could be recreated to obtain one’s identity. Only this encrypted code is stored in the System Control Unit, or the system’s central brain.
For authentication, a biometric verification takes place using the fingerprint device as identifier. Hanscan’s biocryptic SCU is the only entity capable of verifying that the person operating the biometric device is in fact the same person that has enrolled previously with the same credentials. That encrypted code is of no use to anybody or anything else.
Biocryptology® uses a non-lineal (real-time) encryption system that works with an electronic encryptor/decryptor that employs several mechanisms that protect a table of keys that then generates route sequences that randomly select keys from that table. The keys that encrypt and decrypt the relative data change continuously, so it is physically not possible to find the code. This makes it extremely difficult, if not impossible, to reveal the original data.
Unlike algorithms that use a symmetric encryption key, Hanscan uses a large key space (>6,000 different keys). These keys are not stored in software so they don’t travel through the system, nor can any administrator or privileged user gain access to them. Instead they are stored in an encryption device in a secure, fixed place being separated from the SCU. This ensures maximum protection of the keys against theft and any type of external reading. The keys can only be used by the biometric device and the SCU internally.
