Risk assessment for personally identifiable information associated with controlling interactions between computing systems

A method comprising:

• receiving, by a processor, historical data comprising a presence or an absence of detected fraud events for an identity element associated with a user entity, the identity element used in a set of interactions associated with the user entity;
• generating, by the processor, a binomial distribution of the presence or the absence of the detected fraud events for the identity elements in the set of interactions;
• determining, by the processor and based at least in part on the binomial distribution, a risk indicator associated with the identity element;
• determining, by the processor and based at least in part on the risk indicator, a rule controlling subsequent interactions that use the identity element;
• and
• subsequent to determining the risk indicator associated with the identity element, controlling, by the processor and based at least in part on the rule, an interaction involving a target entity and the user entity that is using the identity element.

A non-transitory computer-readable medium comprising instructions that are executable by a processor for causing the processor to perform operations comprising:

• receiving historical data comprising a presence or an absence of detected fraud events for an identity element associated with a user entity, the identity element used in a set of interactions associated with the user entity;
• generating a binomial distribution of the presence or the absence of the detected fraud events for the identity element in the set of interactions;
• determining, based at least in part on the binomial distribution, a risk indicator associated with the identity element;
• determining, based at least in part on the risk indicator, a rule controlling subsequent interactions that use the identity element;
• and
• subsequent to determining the risk indicator associated with the identity element, controlling, based at least in part on the rule, an interaction involving a target entity and the user entity that is using the identity element.
