High Level

Modern facial recognition algorithms make it possible to identify system users by their appearance with a high level of accuracy. In such cases, an image of the user’s face is converted to parameters that later are used in a recognition process. On the other hand, the obtained parameters can be used as data for pseudo-random number generators. However, the closeness of the sequence generated by such a generator to a truly random one is questionable. This paper proposes a system which is able to authenticate users by their face, and generate pseudo-random values based on the facial image that will later serve to generate an encryption key. The generator of a random value was tested with the NIST Statistical Test Suite. The subsystem of image recognition was also tested under various conditions of taking the image. The test results of the random value generator show a satisfactory level of randomness, i.e., an average of 0.47 random generation (NIST test), with 95% accuracy of the system as a whole.

BackgroundOver two-thirds of Natural American Spirit (NAS) smokers believe their cigarettes might be ‘less harmful’, but toxicological evidence does not support this belief. We assessed whether standardised packaging could reduce the possibility of erroneous inferences of ‘safety’ drawn from NAS cigarette packaging.MethodsUS adult smokers (n=909) were recruited to a between-subject survey experiment (3 brands×3 packaging/labelling styles) through Amazon Mechanical Turk and rated their perception of whether a randomly assigned cigarette package conveyed that the brand was ‘safer’ on a three-item scale (Cronbach’s α=0.92). We assessed whether NAS packs were rated higher on the ‘implied safety’ scale than two other brands and estimated the effect that plain packaging (ie, all branding replaced with a drab dark brown colour) and Australian-like packaging (ie, all branding replaced with a drab dark brown colour and a graphic image and text on 75% of the pack surface) had on perceptions of the NAS cigarette package.ResultsSmokers’ ratings of the standard NAS pack on the implied safety scale (mean=4.6; SD=2.9) were 1.9 times (P <0.001) higher than smokers’ ratings of a Marlboro Red pack (mean=2.4; SD=2.3) and 1.7 times (P <0.001) higher than smokers’ ratings of a Newport Menthol pack (mean=2.7; SD=2.4). These perceptions of implied safety were lower when plain packaging was used (Cohen’s d=0.66; P <0.001) and much lower when Australian-like packaging was used (Cohen’s d=1.56; P <0.001).ConclusionThe results suggest that NAS cigarette packaging conveys that its cigarettes are ‘safer’ and that such perceptions are lower with standardised packaging, both with and without warning images.
