Method for generating and verifying security information obtained by means of biometric readings

A method (100) is described for generating security information associated with an entity to be recorded, comprising: carrying out biometric readings on said entity to be recorded to acquire a first (I1) and a second (I2) detection information, separate from each other; - processing (Fl, PPl; F2, PP2, ECE) the information, obtaining a first (cSl) and a second (S4) value having respectively associated the biometric content of said information; applying a function of cryptographic type with at least two operands (RFl) to the first and second value (cSl, S4), obtaining a combination value (S5) from which (IFl) a security label (ID) of said entity to be recorded is generated.
