Systems and methods for generating personalized wager opportunities based on a fantasy sports contest
A gaming system and method of facilitating personalized wager opportunities based on a user-selected fantasy sports team is disclosed. Players may first select athletes for a fantasy sports team. Based on the projected team score for the fantasy sports team selected by the player, a set of wager opportunities may be generated for that player. The wager opportunities may include a set of benchmark point levels and associated odds for the respective levels. Players can place wagers based on whether the actual total score of the fantasy sports team they selected exceeds one or more benchmark point levels and specify the amount to be wagered for each benchmark point level. Thus, a player can make wagers that are won or lost based on the performance of the player's fantasy team compared to the benchmark point levels, regardless of how other players' fantasy sports teams perform. |

Machine learning-based platform for user identification
A system and method are disclosed for identifying a user based on the classification of user movement data. An identity verification system receives a sequence of motion data from a mobile device operated by a target user. From the sequences of motion data, the identity verification system identifies a plurality of identity blocks representing different movements performed by the target user and encodes a set of signature sequences from each identity block into a feature vector. Each feature vector is input to a confidence model to output an identity confidence value for an identity block. An identity confidence value describes a confidence that the movement in the identity block was performed by the target user. The identity confidence value is compared to an operational security threshold and if identity confidence value is above the threshold, the target user is granted access to an operational context. |
