how to collect sitecore information for anonymous

Question

I need to get sitecore information that collected from anonymous users to give him availability to export it or opt out - [GDPR]

any idea about contact ID for anonymous !

Answer 1

The way of doing it is dependent on the sitecore version.

• Sitcore 9 you can use right to be forgotten
• Sitecore 8+ you have to implement the feature from scratch.

Regarding Anonymous user - If the user is really anonymous, then you done need to worry about the GDPR (my view). But sometimes we map user email and sensitive personal info to anonymous user by using forms or WFFM. You can use email address of that user to query xDB (Contact Identifiers) to get the contact and contactID. Then reset informations.

Also: please note that based on WFFFM save action config, anonymous user will store in Core DB and Contact List.

Answer 2

To forget a user, you can use the following code. It will execute the ExecuteRightToBeForgotten function on the contact and scrub their data.

Forget User

public bool ForgetUser()
{
    var id = _contactIdentificationRepository.GetContactId();
    if (id == null)
    {
        return false;
    }

    var contactReference = new IdentifiedContactReference(id.Source, id.Identifier);

    using (var client = _contactIdentificationRepository.CreateContext())
    {
        var contact = client.Get(contactReference, new ContactExpandOptions());
        if (contact != null)
        {
            client.ExecuteRightToBeForgotten(contact);
            client.Submit();
        }
    }

    return false;
}

Fake up some data

public void FakeUserInfo()
{
    var contactReference = _contactIdentificationRepository.GetContactReference();

    using (var client = SitecoreXConnectClientConfiguration.GetClient())
    {
        // we can have 1 to many facets
        // PersonalInformation.DefaultFacetKey
        // EmailAddressList.DefaultFacetKey
        // Avatar.DefaultFacetKey
        // PhoneNumberList.DefaultFacetKey
        // AddressList.DefaultFacetKey
        // plus custom ones
        var facets = new List<string> { PersonalInformation.DefaultFacetKey };

        // get the contact
        var contact = client.Get(contactReference, new ContactExpandOptions(facets.ToArray()));

        // pull the facet from the contact (if it exists)
        var facet = contact.GetFacet<PersonalInformation>(PersonalInformation.DefaultFacetKey);

        // if it exists, change it, else make a new one
        if (facet != null)
        {
            facet.FirstName = $"Myrtle-{DateTime.Now.Date.ToString(CultureInfo.InvariantCulture)}";
            facet.LastName = $"McSitecore-{DateTime.Now.Date.ToString(CultureInfo.InvariantCulture)}";

            // set the facet on the client connection
            client.SetFacet(contact, PersonalInformation.DefaultFacetKey, facet);
        }
        else
        {
            // make a new one
            var personalInfoFacet = new PersonalInformation()
            {
                FirstName = "Myrtle",
                LastName = "McSitecore"
            };

            // set the facet on the client connection
            client.SetFacet(contact, PersonalInformation.DefaultFacetKey, personalInfoFacet);
        }

        if (contact != null)
        {
            // submit the changes to xConnect
            client.Submit();

            // reset the contact
            _contactIdentificationRepository.Manager.RemoveFromSession(Analytics.Tracker.Current.Contact.ContactId);
            Analytics.Tracker.Current.Session.Contact = _contactIdentificationRepository.Manager.LoadContact(Analytics.Tracker.Current.Contact.ContactId);
        }
    }
}
