Anti-counterfeiting Features of Artistic Screening
نویسندگان
چکیده
In a recent publication [Ostromoukhov95], a new image reproduction technique, Artistic Screening, was presented. It incorporates freely created artistic screen elements for generating halftones. Fixed predefined dot contours associated with given intensity levels determine the screen dot shape's growing behaviour. Screen dot contours associated with each intensity level are obtained by interpolation between the fixed predefined dot contours. A user-defined mapping transforms screen elements from screen element definition space to screen element rendition space. This mapping can be tuned to produce various effects such as dilatations, contractions and non-linear deformations of the screen element grid.

RFID Anti-Counterfeiting for Retailing Systems
Counterfeiting is one of the most serious problems in the consumer market. One promising approach for anti-counterfeiting is to attach a low-cost Radio-frequency Identification (RFID) tag to the product authentication. In this paper, we propose an RFID system for detecting counterfeiting products. This RFID system consists of the tag authentication protocol and the database correction protocol....
متن کاملAnti-counterfeiting Using Memory Spots
We propose a new hardware and software solution for anticounterfeiting that puts product authentication directly into the hands of end-users, enabling them to be confident of the authenticity of a product regardless of the integrity of the distribution chain. This is made possible by a new type of tamper-resistant hardware chip, called “memory spot”, which has a unique combination of small size...
متن کاملLightweight Anti-counterfeiting Solution for Low-End Commodity Hardware Using Inherent PUFs
This paper presents a lightweight anti-counterfeiting solution using intrinsic Physically Unclonable Functions (PUFs), which are already embedded in most commodity hardware platforms. The presented solution is particularly suitable for low-end computing devices without on-board security features. Our anti-counterfeiting approach is based on extracting a unique fingerprint for individual devices...
متن کاملDesigning lanthanide-doped nanocrystals with both up- and down-conversion luminescence for anti-counterfeiting.
The widespread forgery in all kinds of paper documents and certificates has become a real threat to society. Traditional fluorescent anti-counterfeiting materials generally exhibit unicolor display and suffer greatly from substitution, thus leading to a poor anti-counterfeiting effect. In this work, unseen but significant enhanced blue down-conversion emission from oleic acid-stabilized lanthan...
متن کاملAnti-counterfeiting: Mixing the Physical and the Digital World
In this paper, we overview a set of desiderata for building anti-counterfeiting technologies that rely upon the difficulty of manufacturing randomized complex 3D objects. Then, we observe how this set is addressed by RF-DNA, an anti-counterfeiting technology recently proposed by DeJean and Kirovski. RF-DNA constructs certificates of authenticity as random objects that exhibit substantial unique...
