Changed

  • Minimal supported SmartFace Platform version is now 4.20.1

    • New configuration field PredictionMilliseconds represents prediction time, if users' face is predicted to be larger than threshold face size in this time, this filter approves the attempt to access
  • Utilizing FaceProcessed notification instead of Match and NoMatch notifications

Access Controller v5_1.7

Release date: 27-May-2022

Release notes

Added

  • Anti-hammering system has been added to prevent brute force attacks. When a spoof is detected, the system blocks the user for a defined period of time. The user is blocked for a longer period of time when more spoofs are detected.
Technical Changelog

Added

  • Spoof filter now supports smarter evaluation of spoofs. This behavior is always evaluated per unique watchlist member and stream. New SpoofRateLimitingConfiguration property was added under existing SpoofCheckConfiguration object. Names and meaning of these properties :

    • Enabled - Defines whether spoof rate limiting filter is enabled. When enabled default SpoofCheck filter evaluation is overridden.

    • SpoofAttemptsCount - number of spoof attempts which must appear to consider spoofing as attack and start blocking period

    • SpoofAttemptsWindowMs - maximum time difference between two spoofs that need to pass to start/prolong blocking

    • BlockingTimeIncrementCooldownMs - if a user is blocked after a spoof attack, all further spoof attempts will be ignored for this defined cooldown period. This should prevent a user from incurring a long block time in a short time span.

    • BlockingTimeIncrementMs - time what will be added to the overall blocking time after spoof attack.

    • MaxBlockingTimeMs - upper limit for blocking time.

Changed

  • AccessNotificationBlocked now contains blocked_until property which contains timestamp until user will no longer beeing blocked

  • New type of BlockReason was added OPENING_TEMPORARILY_BLOCKED. This type of AccessNotificationBlocked will be send when user passed through other evaluation filters but there is ongoing blocking period triggered by RateLimitingConfiguration.

  • GRPC configuration service now also supports updating/reading of new RateLimitingConfiguration.

  • One enum name of AccessNotificationType (in access_notification_service) was renamed from BLACKLIST to BLOCKED.
