Bioencryption is a security method that requires biological data to unlock encryption routines. It covers a wide range of devices, such as fingerprint and retina scans, right up to DNA and full body scans, that are used to unlock anything from doors and compartments, to computer files and operating programs.
While devices of this type have been around for a very long time in all empires, the introduction of cloning technologies saw a rapid change in this field. While much of a persons biological data carries over to a clone, some methods of comparison have proven unreliable. Fingerprints and retina scans in particular proved difficult, and as such, there has been a marked increase in blood and DNA sampling devices, particularly on stations and facilities used primarily by capsuleers.
