The Internet creates infinite possibilities and gives instant explanations by placing the world at our fingertips. But while surfing the net we leave visible traces that businesses use to learn about our individual preferences by analysing the resulting large data sets, meaning that users lose their privacy and autonomy. Big Data, the latest edition in the Silver Niobium series, highlights the dangers and disadvantages of the digital revolution.

Big Data is a field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software. Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating, information privacy and data source. Current usage of the term big data tends to refer to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set. Scientists, business executives, practitioners of medicine, advertising and governments alike regularly meet difficulties with large data-sets in areas including Internet searches, fintech, urban informatics, and business informatics.

The coin contains 9 g of 900 Fine silver in its outer ring and 6.5 g of 998 pure niobium. The coins are boxed with a certificate of authenticity and enclosed in a slipcase.


In its niobium core, depicts a human eye that represents surveillance on the one hand and the biometric method of iris recognition on the other, while the silver outer ring is designed like a camera lens.

A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically. A lens might be permanently fixed to a camera, or it might be interchangeable with lenses of different focal lengths, apertures, and other properties.

Depicts people under surveillance, which is recognisable from the 20:20 running time on the left edge of the outer silver ring, surrounded by the inscription in German "#Mass surveillance". In the foreground of the niobium core, one of a number of human silhouettes is peppered with squares that symbolise the personal data collected about that person.

Mass surveillance is the intricate surveillance of an entire or a substantial fraction of a population in order to monitor that group of citizens. The surveillance is often carried out by local and federal governments or governmental organisations, such as organizations like the NSA and the FBI, but it may also be carried out by corporations (either on behalf of governments or at their own initiative). Depending on each nation's laws and judicial systems, the legality of and the permission required to engage in mass surveillance varies. It is the single most indicative distinguishing trait of totalitarian regimes. It is also often distinguished from targeted surveillance.

Mass surveillance has often been cited as necessary to fight terrorism, prevent crime and social unrest, protect national security, and control the population. Conversely, mass surveillance has equally often been criticized for violating privacy rights, limiting civil and political rights and freedoms, and being illegal under some legal or constitutional systems. Mass surveillance is considered a global issue.
