Method and system for reducing risk score volatility
A method, system and computer-usable medium for performing a risk score volatility reduction operation, comprising: collecting event data associated with user behavior of a user; generating a scoring interval risk score for the user for a current risk scoring interval; and, processing the scoring interval risk score of the current risk scoring interval with a scoring interval risk score from a prior risk scoring window to provide a scoring window risk score, the scoring window risk score reducing volatility of a risk score associated with the user.

performing a risk-adaptive prevention operation, the risk-adaptive prevention operation using the scoring window risk score, the risk-adaptive prevention operation adaptively responding to mitigate risk based upon the scoring window risk score.
2. The method of claim 1 , wherein:
at least one of an average perplexity function and a simple max approach is used when generating the scoring window risk score.
3. The method of claim 1 , further comprising:
associating a risk assessment value with the user behavior.
4. The method of claim 1 , further comprising:
associating a risk score volatility reduction parameter with the user.
