Just got a new Dell Vostro 3550 Laptop which comes with pre-installed software and "new-age" gadgets. Validity Sensors DDK is one of those programs and appears to be part of the computers finger print security which the name seems to imply.
The name of the company that supposedly produces this product is Software Informer, Inc. But a visit to their web site gives absolutely no information (see http://validity-sensors-ddk.software.informer.com/). They claim 4903 people use the product which makes me wonder how they got that info. Does the driver access the internet site and provide info hence the name software informer??? The write up states that a review will be coming soon from their "informers" which appears to mean the user community, but why would the company that produced the software rely on their users to write a review? Shouldn't the company describe the software and then let the users write reviews on the description? How are the users going to write a review on a gadet that that they don't even know what it is or what it's suppose to do?
After much research I found one site that indicated that it's a driver for biometric devices. I uninstalled the software and found no adverse effects. I'm sure it has a use in some circles, but for the average user, it's just a toy which I find annoying.
