PID/(Q)EAA Data Model

The Person Identification Data (PID) is issued by the PID Provider according to national laws. The main scope of the PID is allowing natural persons to be authenticated for the access to a service or to a protected resource. The User attributes provided within the Italian PID are the ones listed below:

  • Current Family Name

  • Current First Name

  • Date of Birth

  • Unique Identifier

  • Taxpayer identification number

The (Q)EAAs are issued by (Q)EAA Issuers to a Wallet Instance and MUST be provided in SD-JWT-VC or MDOC-CBOR data format.

The PID/(Q)EAA data format and the mechanism through which a digital credential is issued to the Wallet Instance and presented to a Relying Party are described in the following sections.

SD-JWT-VC Credential Format

The PID/(Q)EAA is issued in the form of a Digital Credential. The Digital Credential format is SD-JWT as specified in SD-JWT-VC.

SD-JWT MUST be signed using the Issuer's private key. SD-JWT MUST be provided along with a Type Metadata related to the issued Digital Credential according to Sections 6 and 6.3 of [SD-JWT-VC]. The payload MUST contain the _sd_alg claim described in the Section 5.1.1 SD-JWT and other claims specified in this section.

The claim _sd_alg indicates the hash algorithm used by the Issuer to generate the digests as described in Section 5.1.1 of SD-JWT. _sd_alg MUST be set to one of the specified algorithms in Section Cryptographic Algorithms.

Claims that are not selectively disclosable MUST be included in the SD-JWT as they are. The digests of the disclosures, along with any decoy if present, MUST be contained in the _sd array, as specified in Section 5.2.4.1 of SD-JWT.

Each digest value, calculated using a hash function over the disclosures, verifies the integrity and corresponds to a specific Disclosure. Each disclosure includes:

  • a random salt,

  • the claim name (only when the claim is an object element),

  • the claim value.

In case of nested object in a SD-JWT payload each claim, on each level of the JSON, should be individually selectively disclosable or not. Therefore _sd claim containing digests MAY appear multiple times at different level in the SD-JWT.

For each claim that is an array element the digests of the respective disclosures and decoy digests are added to the array in the same position of the original claim values as specified in Section 5.2.4.2 of SD-JWT.

In case of array elements, digest values are calculated using a hash function over the disclosures, containing:

  • a random salt,

  • the array element

In case of multiple array elements, the Issuer may wish to conceal presence of any statement while also allowing the Holder to reveal each of those elements individually (Section 5.2.6 SD-JWT). Both the entire array and the individuals entries can be selective disclosure.

The Disclosures are provided to the Holder together with the SD-JWT in the Combined Format for Issuance that is an ordered series of base64url-encoded values, each separated from the next by a single tilde ('~') character as follows:

<Issuer-Signed-JWT>~<Disclosure 1>~<Disclosure 2>~...~<Disclosure N>

See SD-JWT-VC and SD-JWT for additional details.

MDOC-CBOR

The PID/(Q)EAA MDOC-CBOR data model is defined in ISO/IEC 18013-5, the standard born for the the mobile driving license (mDL) use case.

The MDOC data elements MUST be encoded as defined in RFC 8949 - Concise Binary Object Representation (CBOR).

The PID encoded in MDOC-CBOR format uses the document type set to eu.europa.ec.eudiw.pid.1, according to the reverse domain approach defined in the EIDAS-ARF and ISO/IEC 18013-5.

The document's data elements utilize a consistent namespace for the mandatory Mobile Driving License attributes, while the national PID attributes use the domestic namespace eu.europa.ec.eudiw.pid.it.1, as outlined in this implementation profile.

In compliance with ISO/IEC 18013-5, the MDOC data model in the domestic namespace eu.europa.ec.eudiw.pid.it.1, requires the following attributes:

Attribute name

Description

Reference

version

tstr (text string). Version of the data structure being used. It's a way to track changes and updates to the standard or to a specific implementation profile. This allows for backward compatibility and understanding of the data if the standard or implementation evolves over time.

[ISO 18013-5#8.3.2.1.2]

status

uint (unsigned int). Status code. For example "status":0 means OK (normal processing).

[ISO 18013-5#8.3.2.1.2.3]

documents

bstr (byte string). The collection of digital documents. Each document in this collection represents a specific type of data or information related to the Digital Credential.

[ISO 18013-5#8.3.2.1.2]

Each document within the documents collection MUST have the following structure:

Attribute name

Description

Reference

docType

tstr (text string). Document type. For the PID, the value MUST be set to eu.europa.ec.eudiw.pid.1. For an mDL, the value MUST be org.iso.18013-5.1.mDL.

[ISO 18013-5#8.3.2.1.2]

issuerSigned

bstr (byte string). It MUST contain the Mobile Security Object for Issuer data authentication and the data elements protected by Issuer data authentication.

[ISO 18013-5#8.3.2.1.2]

The issuerSigned object MUST have the following structure:

Attribute name

Description

Reference

nameSpaces

bstr (byte string) with tag 24 and major type 6. Returned data elements for the namespaces. It MAY be possible to have one or more namespaces. The nameSpaces MUST use the same value for the document type. However, it MAY have a domestic namespace to include attributes defined in this implementation profile. The value MUST be set to eu.europa.ec.eudiw.pid.it.1.

[ISO 18013-5#8.3.2.1.2]

issuerAuth

bstr (byte string). Contains Mobile Security Object (MSO), a COSE Sign1 Document, issued by the Credential Issuer.

[ISO 18013-5#9.1.2.4]

During the presentation of the MDOC-CBOR credential, in addition to the objects in the table above, a deviceSigned object MUST also be added. deviceSigned MUST NOT be included in the issued credential provided by the PID/(Q)EAA Issuer.

Attribute name

Description

Reference

deviceSigned

bstr (byte string). Data elements signed by the Wallet Instance during the presentation phase.

[ISO 18013-5#8.3.2.1.2]

Where the deviceSigned MUST have the following structure:

Attribute name

Description

Reference

nameSpaces

tstr (text string). Returned data elements for the namespaces. It MAY be possible to have one or more namespaces. It MAY be used for self-attested claims.

[ISO 18013-5#8.3.2.1.2]

deviceAuth

bstr (byte string). It MUST contain either the DeviceSignature or the DeviceMac element.

[ISO 18013-5#8.3.2.1.2]

Note

A deviceSigned object given during the presentation phase has two purposes:

  1. It provides optional self-attested attributes in the nameSpaces object. If no self-attested attributes are provided by the Wallet Instance, the nameSpaces object MUST be included with an empty structure.

  2. Provide a cryptographic proof attesting that the Holder is the legitimate owner of the Credential, by means of a deviceAuth object.

Note

The issuerSigned and the deviceSigned objects contain the nameSpaces object and the Mobile Security Object. The latter is the only signed object, while the nameSpaces object is not signed.

nameSpaces

The nameSpaces object contains one or more IssuerSignedItemBytes that are encoded using CBOR bitsring 24 tag (#6.24(bstr .cbor), marked with the CBOR Tag 24(<<... >>) and represented in the example using the diagnostic format). It represents the disclosure information for each digest within the Mobile Security Object and MUST contain the following attributes:

Name

Encoding

Description

digestID

integer

Reference value to one of the ValueDigests provided in the Mobile Security Object (issuerAuth).

random

bstr (byte string)

Random byte value used as salt for the hash function. This value SHALL be different for each IssuerSignedItem and it SHALL have a minimum length of 16 bytes.

elementIdentifier

tstr (text string)

Data element identifier.

elementValue

depends by the value, see the next table.

Data element value.

The elementIdentifier data that MUST be included in a PID/(Q)EAA are:

Namespace

Element identifier

Description

eu.europa.ec.eudiw.pid.1

issue_date

full-date (CBORTag 1004). Date when the PID/(Q)EAA was issued.

eu.europa.ec.eudiw.pid.1

expiry_date

full-date (CBORTag 1004). Date when the PID/(Q)EAA will expire.

eu.europa.ec.eudiw.pid.1

issuing_authority

tstr (text string). Name of administrative authority that has issued the PID/(Q)EAA.

eu.europa.ec.eudiw.pid.1

issuing_country

tstr (text string). Alpha-2 country code as defined in [ISO 3166].

Depending on the Digital Credential type, additional elementIdentifier data MAY be added. The PID MUST support the following data:

Namespace

Element identifier

Description

eu.europa.ec.eudiw.pid.1

given_name

tstr (text string). See PID Claims fields Section.

eu.europa.ec.eudiw.pid.1

The issuerAuth represents the Mobile Security Object which is a COSE Sign1 Document defined in RFC 9052 - CBOR Object Signing and Encryption (COSE): Structures and Process. It has the following data structure:

  • protected header

  • unprotected header

  • payload

  • signature.

The protected header MUST contain the following parameter encoded in CBOR format:

Only the Signature Algorithm MUST be present in the protected headers, other elements SHOULD not be present in the protected header.

The unprotected header MUST contain the following parameter:

Element

Description

Reference

x5chain

Identified with the label 33

RFC 9360 CBOR Object Signing and Encryption (COSE) - Header Parameters for Carrying and Referencing X.509 Certificates.

Note

The x5chain is included in the unprotected header with the aim to make the Holder able to update the X.509 certificate chain, related to the Mobile Security Object issuer, without invalidating the signature.

The payload MUST contain the MobileSecurityObject, without the content-type COSE Sign header parameter and encoded as a byte string (bstr) using the CBOR Tag 24.

The MobileSecurityObjectBytes MUST have the following attributes:
