Systems, apparatus, and methods for authorizing a transaction initiated by a consumer are provided. A likelihood function can approximate a pattern of previous transactions and provide a measure of how likely it is for a transaction to occur as a function of time. The time of a current transaction can be used to determine a corresponding likelihood value of a likelihood function associated with the transaction. The likelihood value can then be used to determine a score for authorizing the transaction. As the likelihood corresponds to a particular time of a pattern, the score can be tailored to the current transaction and achieve greater accuracy. |
