TL;DR: The product of subsequent partial sums of independent, identically distributed, square integrable, positive random variables is asymptotically lognormal as discussed by the authors, which extends in a rather routine way to non-degenerate U-statistics.

TL;DR: This research addresses the creation and detection of fake reviews, and shows that a machine classifier can accomplish this goal near-perfectly, whereas human raters exhibit significantly lower accuracy and agreement than the tested algorithms.

TL;DR: A portable authentication device and method of authenticating products or packaging by analyzing key ingredients on products or on product packaging is disclosed in this article, where the device includes an assembly for providing a source of light to irradiate the ink containing the light sensitive compound on the sample product or product package, an optical detector to detect certain spectral properties emitted or absorbed by the irradiated ink and a controller to determine the authenticity of the sample products or product packages by comparing the emitted and absorbed properties to a standard.
Abstract: A portable authentication device and method of authenticating products or packaging by analyzing key ingredients on products or on product packaging is disclosed. Light-sensitive compounds can be used to identify the product or product packaging. The product or product package may include visible or invisible ink containing a particular light-sensitive compound. The ink may be printed in one or more locations on the product or product packaging to produce an authentication mark, such as a bar code. The device includes an assembly for providing a source of light to irradiate the ink containing the light sensitive compound on the sample product or product package, an optical detector to detect certain spectral properties emitted or absorbed by the irradiated ink and a controller to determine the authenticity of the sample product or product package by comparing the emitted or absorbed properties to a standard.
