Abstract

The project is a study into the feasibility (phase 1) and the implementation (phase 2) of devices for the extraction of features and the verification of a digital fingerprint, through the use of an image capturing sensor based on network capacitance CMOS (semiconductor) and a high performance digital signal processor, resulting in the first commercial device of its type to be developed in Latin America. The main characteristics of this proposed device are: implementation using innovative algorithms developed here in Brazil, thus improving the processes involved (image capturing, treatment, extraction of characteristics, storage and comparison); interface inclusion for smart cards, introducing a new security element in the transport and storage of digital fingerprint characteristics and off-line verification; use of devices based entirely on semiconductors, with no optical part for image capturing, rendering circuits more robust and much more compact; low number of components (processor, memory and sensor), small motherboard area, commercially available and locally made components; standardized communication interfaces, facilitating the integration with existing systems or products (OEM) or for the development of new products.
