Abstract:
1. An authentication challenge system comprising: one or more hardware processor, comprising: a question generation engine, to derive a series of one or more questions based upon activity associated with an account of an online store, the series of questions to authenticate a user to the account on the online store, wherein each account of the online store is assigned one or more at least quasi-unique identifiers; a confidence engine, to determine an identity confidence level based on the activity associated with the account and compute the identity confidence level for a successful authentication; and a quality engine, to adjust the question generation engine and the confidence engine based upon an analysis of question and answer metrics across multiple accounts of the online store, wherein the online store includes digital media including at least one of music, movies, books or apps, wherein the quality engine is to apply a machine-learning algorithm to analyze question and answer metrics for multiple user accounts to modify the series of questions to improve a probability of detecting accounts with compromised credentials.
