What is the operating range of SureSign detection software?
There are three general cases where a valid SureSign fingerprint may be outside the detection range of the detector tools: (1) If the size of the image is too small, the detection tools may discover the presence of a fingerprint but be unable to fully decode the IDs. A warning is given in this case, however. The minimum image size to ensure successful detection is around 50KB although, in practice, a fingerprint may be detected in as little as 30KB of image data using the latest SureSign detection tools. (2) If the image has been heavily manipulated by transformations such as distortion, rotation or re-sizing. Typically, in these cases, the fingerprint is still present in the data but may not be detectable. The detector is tolerant of a range of rotation and enlargement, but if the image has been manipulated outside this range, then it should be transformed back within range before the Detector will successfully recover the fingerprint.
