Will the fingerprint survive lossy data compression such as JPEG?
In general, yes, but since data compression techniques work by discarding varying degrees of image information and, if excessive levels of compression are used, the fingerprint could be difficult to detect in some circumstances. However, this usually only occurs at the point at which the data becomes unusable for quality reproduction anyway. Tests have shown that a SureSign fingerprint can survive compression ratios of up to 30:1.
