The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.…

A cloud application, or cloud app, is a software program where cloud-based and local components work together. This model relies on remote servers for processing logic that is accessed through a web browser with a continual internet connection. Cloud application servers typically are located in a remote data center operated by a third-party cloud services infrastructure provider. Cloud-based application tasks may encompass email, file storage and sharing, order entry, inventory management, word processing, customer relationship management (CRM), data collection, or financial accounting features.…

Machine vision is the ability of a computer to see; it employs one or more video cameras, analog-to-digital conversion (ADC) and digital signal processing (DSP). The resulting data goes to a computer or robot controller. Machine vision is similar in complexity to voice recognition.…

Biometrics is the measurement and statistical analysis of people's unique physical and behavioral characteristics. The technology is mainly used for identification and access control or for identifying individuals who are under surveillance. The basic premise of biometric authentication is that every person can be accurately identified by their intrinsic physical or behavioral traits. The term biometrics is derived from the Greek words bio, meaning life, and metric, meaning to measure.…

Biometric security procedure for the manufacture of identity cards and credit cards, visas and passports containing a face image (5) of the holder, including the steps of carrying out an analysis of face features corresponding to said face image (5), comparing said features with master/pattern features of a data base, and obtaining by said analysis a set of master/pattern features that is characteristic of the face image of the holder. Said set of master/pattern features corresponds to a specific numeric encoding determined by a number of each of the master/pattern features making up said set of master/pattern features. Said numeric encoding or a corresponding colour encoding made up by coloured lines in form of a grecque or filigree, is printed on the identity card. The invention also relates to a procedure for authentication of an identity or credit card, visa or passport manufactured according to the procedure of the invention, and to a procedure of facial recognition.…

Visible Light Facial Recognition is the latest technology, aimed to overcome shortcomings of previous facial recognition and achieve an all-rounded upgrade on whatever performance and reliability by using Deep Learning. Facial Recognition has been considered as one of the rising biometric technologies and many are optimistic about its development in the future. However, the technological incapability of facial recognition has also been exposed along with the increasing usage in our daily life, mainly in the ability of anti-spoofing, threshold of processing power, environmental restriction on light source and pose of angle.…
