Method for authenticating a document

An authenticating method for authenticating an identity of a person comprising:

• performing an authenticating method for authenticating a document of the person comprising:
• receiving one or more obtained images of the document;
• detecting one or more elements of the document;
• obtaining at least one parameter of the detected elements, by processing the one or more obtained images of the document using a first image processing method;
• determining at least one meta-characteristic by comparing at least one parameter of the detected elements to at least one reference parameter of one or more pre-obtained elements;
• determining an authenticity indicator of the document by verifying whether the at least one meta-characteristic is within at least one predefined threshold associated with the at least one meta-characteristic, wherein the at least one meta-characteristic is at least one measurement of a difference of at least one parameter of a detected element relative to at least one reference parameter of at least one reference model, the reference model comprising the one or more pre-obtained elements;
• the document being an ID document;
• the authenticating method for authenticating an identity of a person further comprising:
• receiving one or more first face images of the person;
• receiving one or more second face images of the person included in the ID document by processing one or more images of the ID document using a second image processing method, the one or more images of the ID document being received by the authenticating method performed for authenticating the ID document;
• determining an alikeness indicator by comparing the one or more first face images and the one or more second face images, using the second processing method;
• and authenticating the identity of the person depending on a result of the authenticating method performed for authenticating the ID document and whether the determined alikeness indicator is within an alikeness threshold.

A computing device comprising a memory and a processor, embodying instructions stored in the memory and executable by the processor, the instructions comprising functionality to execute an authenticating method for authenticating a document comprising:

• receiving one or more obtained images of the document;
• detecting one or more elements of the document;
• obtaining at least one parameter of the detected elements, by processing the obtained one or more images of the document using an image processing method;
• determining at least one meta-characteristic by comparing at least one parameter of the detected elements to at least one reference parameter of one or more pre-obtained elements;
• determining an authenticity indicator of the document by verifying whether the at least one meta-characteristic is within at least one predefined threshold associated with the at least one meta-characteristic, wherein the at least one meta-characteristic is at least one measurement of a difference of at least one parameter of a detected element relative to at least one reference parameter of at least one reference model the reference model comprising the one or more pre-obtained elements.
