Signature Service

Signature Service

Signature Service Overview

The Freja Signature Service allows Relying Parties to securely deliver messages to a user, as well as to prompt Freja end users to digitally sign data and documents.

This is available to all Freja users regardless of registration level, provided they have registered a Freja account with an email at least. Signatures created by the end users are PKI-based and therefore non-repudiable.

The signature flow is practically identical to authentication described in Authentication Service. The main difference is that while simultaneous authentication requests are not possible and are limited to 2 minutes, a user may have multiple signature requests pending for up to 30 days.

This allows for flexible signing solutions to be built on top of Freja where users can be prompted to sign even outside a direct online context.

Signature Types

Freja eID allows for several types of signatures.

Simple Signatures

The Simple signature type allows signing of UTF-8 text. Upon completion of the signature by the user, the Relying Party receives a JWS structure containing the data that was presented to the user, as well as evidence that the Freja eID infrastructure has validated the signature.

Extended Signatures

The extended signature type allows signing of UTF-8 text (presented to the user) alongside binary data (not presented to the user). Upon completion of the signature by the user, the Relying Party receives a JWS structure containing the data that was presented to the user and the supplied binary data, as well as evidence that the Freja eID infrastructure has validated the signature.

Advanced Signatures

The advanced signature type allows signing of UTF-8 text (presented to the user), binary data (not presented to the user) or both with one-time certificates tied to the end-user's personal data and that can be validated independently outside Freja. Note that no revocation data is supplied for the signing certificates as they are generated under user consent for one-time usage and are implicitly valid at the time of signing. The advanced signature is returned as part of the ordinary response signed by Freja eID. Currently supported advanced signature formats are listed in the table below:

QR Code Signing

QR code signing is supported by the Freja eID Signature service. In essence, a user signs transaction by scanning a generated QR code and approving the signature action.

On mobile the process is even simpler since the user does not need to scan a QR code physically. Everything takes place within their device thereby making signatures even more secure because the process is initiated and approved on the same device. In addition, this method is the most user friendly since it foregoes typing in user identifiers (emails, phone numbers, social security number etc.).

In summary, we recommend implementing QR code signing because:

  • It is much more user friendly, especially on mobile.

  • It is a much safer method of signing.

This document goes more into depth regarding the Freja eID API. If you would like to see more details QR code login implementation, please refer to this page about Implementation and Best Practices.

Dynamic QR Code Implementation

If you would like more information about implementing dynamic QR codes, refer to this dedicated page about Dynamic QR Code Implementation.

Don’t Forget

There are several technical requirements that must be in place before implementation can begin. Please refer to the section 'Before You Begin' on this page.

Methods in the Signature Service

The Freja eID Relying Party Signature Service allows you to:

  1. Initiate a signature request;

  2. Get one signature result;

  3. Get multiple signature results;

  4. Cancel a signature request.

When it comes to getting signature results, we recommend using the method for multiple results to reduce the number of polling requests.

Initiate Sign Method

This method is used by a Relying Party to initiate a sign transaction. This method is intended for creating signatures both in online contexts, where the access to the Relying Party's service or application is initiated by the end user, as well as in offline contexts, where the signature request is initiated by the Relying Party's service in its own right. Signature transactions, therefore, have configurable longevity — from the point of initiation, the user has between two minutes and 30 days to confirm the signature request. As opposed to authentication requests, multiple signature requests may be active at any given time, from the same or different Relying Parties.

Although in most cases possession and control of the handheld device on which a Freja mobile application is installed are sufficient for allowing the user to view transaction content when initiating a transaction, a Relying Party can also specify whether the content is confidential or not. The confidentiality flag governs whether the user must enter their PIN or, if enabled, use one of the biometric authentication alternatives on the handheld device, before being allowed to view the content of the transaction. The option effectively provides an option to have transactions that are "signed-for (for viewing) with explicit consent (for accepting the content)".

The method is called using HTTP POST through the URLs below:

JSON Example for initSignRequest

The parameter of the method is a Base64 UTF8-encoded JSON payload according to the following:

{ "userInfoType":"User info type", "userInfo":"User information corresponding to user info type", "minRegistrationLevel":"Minimum required registration level of a user", "userConfirmationMethod":"Method used to confirm user's identity", "useDynamicQrCode":"Flag to enable dynamic QR code", "title":"Title to display in transaction list", "pushNotification":{ "title":"Title to display in push notification to user", "text":"Text to display in push notification to user" }, "expiry":"Expiry time for the request", "dataToSignType":"Type of data to sign", "dataToSign":"The data to be signed", "signatureType":"Signature type", "attributesToReturn":[ { "attribute":"Type of attribute to be returned" } ] }
  • userInfoType: string, mandatory. Describes the type of user information supplied to identify the end user. Currently one of:

    • INFERRED (for QR code signature transactions),

    • PHONE (end user's telephone number),

    • EMAIL (end user's email),

    • SSN (end user's social security number).

    • UPI (end user’s unique personal identifier in Freja).

  • userInfo: string, mandatory, 256 characters maximum.

    • If userInfoType is INFERRED, then userInfo must be set to: "N/A" because there is no data for the user to enter.

Inferred transactions are not bound to a specific user upon initiation, they are bound to a user when a QR code is scanned. That is, the first user that scans the QR code of a pending inferred transaction gets bound to it.

As such you need to be aware of the privacy of the content contained in signature request: if the content is sensitive and intended for a specific recipient we strongly advise you to use one of the binding forms of the signature API.

  • userInfo: string, mandatory, 256 characters maximum.

    • If userInfoType is EMAIL or PHONE, interpreted as a string value of the email or telephone number of the end user, respectively.

For userInfoType set to PHONE, the value must be in the following format: "+4673*******"; the leading '+' sign is present, but the leading '0' for the mobile phone operator code is not.

  • userInfo: string, mandatory, 256 characters maximum.

    • For userInfoType set to SSN, is must be a Base64 encoding of the ssnuserinfo JSON structure as follows:

{     "country":"Country of SSN",     "ssn":"Social security number of the end user" }

Where:

  • country: string, mandatory. Contains the ISO-3166 two-alphanumeric country code of the country where the SSN is issued. In the current version of Freja eID, one of: ''SE'' (Sweden), ''NO'' (Norway), ''FI'' (Finland), ''DK'' (Denmark).

  • ssn: string, mandatory. Expected SSN of the end user as per pre-registration.

    • If country equal to "SE", the value must be the 12-digit format of the Swedish "personnummer" without spaces or hyphens. E.g. 195210131234.

    • If country equal to ''NO'', the value must be the 11-digit format of the Norwegian "personnummer" without spaces or hyphens. E.g. 13105212345.

    • If country equal to ''FI'', the value must be the 10-characters format of the Finish ''koodi'', with the hyphen before the last four control characters. The hyphen can be replaced with the letter A. E.g. 131052-308T or 131052A308T.

    • If country equal to ''DK'', the value must be the 10-digit format of the Danish "personnummer" without spaces or hyphens. E.g. 1310521234.

  • minRegistrationLevel: string, optional. Minimum required registration level of a user in order to approve/decline a signature request. Can be BASIC, EXTENDED, PLUS or INFERRED. If not present, default level will be BASIC.

Concerning minRegistrationLevel

When set to INFERRED, the transaction can proceed without enforcing a specific registration level. Instead, the system will infer and use the user's actual registration level at runtime.

The set of returned attributes will vary based on the user's actual level.

For example, if the BASIC_USER_INFO attribute is requested and the user is at the BASIC level, the attribute will not be returned (null), as it is not available at that level. If the user is at EXTENDED or PLUS, the attribute will be included in the response.

In order to be able to use INFERRED as the minimal registration level, you must first get in touch with partnersupport@frejaeid.com.

  • userConfirmationMethod: string, optional. Used to specify the method by which the user's identity is confirmed when performing an action. Can be DEFAULT or DEFAULT_AND_FACE.

  • useDynamicQrCode: boolean, optional. Used to specify whether a dynamic QR code will be used.

  • title: string, optional, 128 characters maximum. This title will be displayed to the user in the Freja mobile application. The title will be presented regardless of the confidentiality setting (see below). If not present, a system default text will be presented.

  • pushNotification: JSON structure, optional. The title and the text of the notification sent to the mobile device to alert the user of a signature request. The character limit for the push notification title and text is 256 characters for each. If not present, a system default title and text will be presented.

  • expiry: long, optional. Describes the time until which the Relying Party is ready to wait for the user to confirm the signature request. Expressed in milliseconds since January 1, 1970, 00:00 UTC. Min value is current time +2 minutes, max value is current time +30 days. If not present, defaults to current time +2 minutes. 
    Maximum expiry time for transactions with user info type INFERRED is current time +30 minutes. If not present, defaults to current time +2 minutes.

  • dataToSignType: string, mandatory. Describes the type of data to be signed. Currently, SIMPLE_UTF8_TEXT and EXTENDED_UTF8_TEXT are supported.

  • dataToSign: JSON structure, mandatory. Subject to dataToSignType; If SIMPLE_UTF8_TEXT, then all of dataToSign will be displayed to the user prior to asking for signature approval. JSON structure described below.

  • dataToSign: JSON structure, mandatory. Subject to dataToSignType; If EXTENDED_UTF8_TEXT, then one part will be displayed to the user prior to asking for signature approval, while the binaryData part of dataToSign will not. JSON structure described below.

    • EXTENDED_UTF8_TEXT

{ "text":"Base64 encoded UTF-8 text displayed to the end user" "binaryData":"Base64 encoded byte array not displayed to the user" }

text: string, mandatory, 4096 plain text characters maximum prior to Base64 encoding. The text that will be shown in the mobile application and signed by the end user. The content of the Base64 string are bytes representing a UTF-8 encoding of the text to be displayed to and signed by the user.

binaryData: string, mandatory, 5 MB maximum prior to Base64 encoding. This is not shown to the user in the mobile application but is, nonetheless included in the signature.

  • signatureType: string, mandatory. The type of signature that is requested. Currently, SIMPLE, EXTENDED and XML_MINAMEDDELANDEN are supported and must match the dataToSignType parameterSIMPLE signature type supports SIMPLE_UTF8_TEXT data to sign type, EXTENDED signature type supports EXTENDED_UTF8_TEXT data to sign type and XML_MINAMEDDELANDEN supports SIMPLE_UTF8_TEXT data to sign type.
