A PPENDIX C – V-PASS T EMPLATE D IFFERENCES

Appendix C – V-PASS Template Differences

The V-PASS product is similar in size and shape to both the VeriFlex and VeriProx

products. However, it incorporates a very different biometric comparison process. The

VeriFlex and VeriProx perform a 1:1 verification. One finger is compared with one template

to decide if there is a match. A Template ID is mandatory to determine which of the stored

templates to compare with the current live fingerprint image.

The V-PASS performs a “searching” algorithm that will compare the current live fingerprint

image with ALL templates that reside on the V-PASS unit (up to 200 with firmware version

3.0). This is often referred to as 1:many (one to many) or “identification”. Whereas the

VeriProx and VeriFlex are typically used with a proximity card or external device to indicate

a user’s ID, the V-PASS no longer requires this extra form of identification, only the

fingerprint is required.

To perform this quick database search of all enrolled templates, the V-PASS requires a

fingerprint template that is different then the fingerprint templates required for the VeriFlex

and V-Pass. The VeriFlex / VeriProx templates are 348 bytes of data, whereas the V-PASS

template is 2,532 bytes of data.

The V-PASS template contains all the data from a VeriFlex/VeriProx template and more.

Bioscrypt provides a way to generate a 1:1 VeriFlex / VeriProx template from a V_PASS

template. This conversion is available in our SDK for software developers, or as part of the

VeriAdmin Management Software for end-users.

Users should be aware of the following:

1. V-PASS templates are different then VeriFlex / VeriProx templates.

2. V-PASS templates should use the default extension of “.mtm”

3. VeriProx / VeriFlex templates should use the default extension of “.tem”

4. Only a V-PASS can create (“enroll”) a V-PASS template.

5. A V-PASS template CAN BE converted to a VeriFlex / VeriProx template.

6. A VeriProx / VeriFlex template CANNOT be converted to a V-PASS template.

7. Administrators need to be aware of these differences if BOTH products are used.

8. A Veri-Series unit will reject a template if the wrong type is sent. This means that a

VeriProx / VeriFlex will return an error if a V-PASS template is sent to that unit. The

same is true if a V-PASS unit is sent a VeriFlex / VeriProx template.

9. Administrators should use caution when attempting Broadcast commands on a

“Mixed” Network.. Broadcast commands will work, but #8 above will apply. Contact

Bioscrypt Technical Services for more information.
