Distance From Last

Find The: Distance From Last

distance_from_last

The distance from the location of the current event to the location of the most recent event matching the criteria.

For example:

The distance travelled between the current event and the most recent login. A large distance can trigger a step-up challenge or expire the session.
Distance of a shipping address from the last order.
In some gaming use cases, knowing that a user moves large distances frequently can mitigate regulatory risk.

Configuration

Feature Name: The "dictionary" name under which the feature value will be stored and referenced by in rules.
Coordinate Attribute: The attribute holding the location. It must have the Coordinate data type; anything else is rejected at build time.
In Units: kilometers or miles. Required.
For Events:
- With The Same: Provides a way of filtering past events based on the attribute values. There must be at least one Identifier and only Identifier and Subject attributes can be used.

Optional Configuration

Default Value: A value that can be assigned to the feature if the attributes to calculate the features are not present.
Scope: Can be used to extend the event search from the local node, to all nodes within the same organization all the way to all across customers (global).
For Events:
- All event types: Default, no filter
- Same as current: Filter by event_type of event being processed
- Specific event type: List out the event_type to restrict to, as a list. Example: only consider account_login_success.
Condition: A Query-Language filter that can be used to refine Features for specific use cases.
Time Window: Can be used to limit the Feature calculation to a specific time period/window. e.g 1 week. Default is all ; no time window
Starting: Can be used to remove recent events from Feature calculation. Default is immediately ; no lag.

Use Case 1
