In this article we will try to breakdown the concepts and terminology behind SSI, as well as the reasoning for its increasing traction particularly in Europe. Traditionally speaking human beings are identified through reference, claims made by ourselves are generally regarded as useless if there is no one to “back them up”, so to speak. As an example a statement by an individual that he is a citizen of country X is meaningless if he does not possess a passport i.e. a claim, issued to him by a trusted third party, in this case a government.
To combat this problem governments and later businesses started issuing attestations about certain claims. Sometimes these claims are directly tied to an individual, in which case the documents stating those claims carry a photograph of the said individual or a serial number, often referred to as a tax or personal number. Other claims simply state that they belong to the holder, in which case whoever possesses the claim is also its owner or can state that the claim refers to them. As the time passed new concepts were introduced, such as a legal person, the idea that an incorporeal construct or agreement can also have an identity. In the following text we will use the term entity to denominate both terms.
