Token - Bio Token
|
Bio-tokens, also known as
pseudo-tokens, combine the functionality of a
fingerprint reader and a token authentication device,
and are enhanced by the ability to store data directly
on the device. That is, a bio-token will store the
authentication credentials (i.e., fingerprint template
used for comparison during the verification and
identification processes) on the card itself. This
allows users to carry a bio-token card to another
machine and authenticate their identity without their
template data being stored on the machine or network.
Hence, a user must not only provide their fingerprint,
but also have the appropriate bio-token in their
possession. A single bio-token has the ability to store
multiple user data, so users can share the device. Users
can also store other data (such as documents) on their
bio-token. If multiple users are sharing one device and
have stored data/documents on the device, the currently
logged on individual will only have access to their own
data. Hence, data stored on a bio-token is secure,
accessible only to the person who is currently
authenticated. |
