1. A method for generating an electronic signature comprising:
receiving at least one first physical characteristic representative of a person, the first physical characteristic containing a first biometric feature of the person;
identifying the first biometric feature in the received first physical characteristic;
generating a first biometric mathematical representation representing the first biometric feature of the person;
receiving a content to be signed;
generating a first content mathematical representation representing the content to be signed;
storing the first biometric mathematical representation and the first content mathematical representation in a signature dataset;
computing a first signature mathematical representation of the signature dataset;
authenticating the signature dataset, comprising:
obtaining the first signature mathematical representation of the signature dataset;
obtaining the signature dataset;
computing a second signature mathematical representation of the obtained signature dataset; and
the method further comprising, responsive to the first signature mathematical representation and the second signature mathematical representation being equal, authenticating the electronic signature.
