What is the difference between one-to-one and one-to-many fingerprint matching algorithms?
What is the difference between one-to-one and one-to-many fingerprint matching algorithms? | A one-to-many algorithm identifies and authenticates a person using the fingerprint as the only piece of information. As the fingerprint is submitted for authentication, it is compared against all the fingerprints from all the persons enrolled until it finds a match. A one-to-one algorithm uses a specific unique identifier (like a username) to determine which person is about to attempt authentication. As the fingerprint is submitted, it is compared against only the fingerprints from the person determined by the unique identifier. One-to-one matching algorithms are simpler and therefore more secure and efficient for most biometric authentication systems. |

Are images of the fingerprint stored anywhere?
Are images of the fingerprint stored anywhere? | No. Ceelox stores a “pattern”, also referred to as an “enrolled biometric template” or a mathematical description of your fingerprint in order to “recognize” your fingerprint as belonging to you. It is not at all an image of the fingerprint itself, but rather a description of it. A description that is accurate enough to ensure your fingerprint will not be confused for another - while being simple enough to make the matching efficient and fast. |

How is a biometric template generated?
How is a biometric template generated? | A pattern is found by taking key characteristic measurements of the shape of the lines that constitute the fingerprint. Some common key characteristics that are used for this purpose are ridges and bifurcations of the finger. These are now commonly referred to as Minutia points. The principle behind this is that two different images of the same fingerprint will still present the same Minutia points if they are in fact from the same fingerprint. The algorithms to generate these templates are constantly improved and depurated; Ceelox’s architecture was designed with these constant changes in mind allowing modular capability to ensure the best algorithms are always available through our products. |

What type of security does Ceelox provide for storing biometric templates?
What type of security does Ceelox provide for storing biometric templates? | All biometric templates are stored with robust Rijndael AES256 encryption, and in the form of an Enrolled Bio-Template. By definition an Enrolled Bio-Template cannot be used to authenticate against itself so it is not possible to substitute a live sample of a legitimate fingerprint with an Enrolled Bio-Template. |

What type of security does Ceelox provide for storing passwords?
What type of security does Ceelox provide for storing passwords? | Passwords that grant access to our applications are first hashed with SHA-1, then stored, then encrypted with Rijndael AES256. Passwords that are used by Ceelox applications to submit as credentials to another application are kept encrypted with Rijndael AES256. |

I plug in the Ceelox Vault™ but nothing happens. What can I do?
I plug in the Ceelox Vault™ but nothing happens. What can I do? | There may be a problem with the drivers used by the device. Try to reboot your PC and see if that addresses the problem. If Ceelox Vault™ still does not automatically start when you plug the device in, it is possible that the auto run feature on your PC is not operational. In order to manually start Ceelox Vault™, simply follow these steps: - Use Windows Explorer to access the “CeeloxVault” area of your portable device.
- If you are using a Flash Stick, run the program “VaultLoader.exe” to start Ceelox Vault™.
- If you are using an external Hard Drive, run the program “RunCeeloxVault.exe” to start Ceelox Vault™.

How do I remove an enrolled person’s fingerprint from Ceelox Vault™?
How do I remove an enrolled person’s fingerprint from Ceelox Vault™? | Any Additional Fingerprint (other than the two primary ones used to create the Vault) needs a positive match before it can be removed. This is so that IT and Security administrators can be assured that they will always have access to their user’s Vaults. |

My Ceelox Vault™ icon disappeared, how do I get it back?
My Ceelox Vault™ icon disappeared, how do I get it back? | You can manually restart Ceelox Vault™ by selecting “Ceelox Vault™” from your program menu, or by re-plugging in the device, or by opening the drive unit and running the launcher program. |
