Abstract
An access monitoring and control system is provided. The access monitoring and control system includes a sensing device configured to collect data points regarding at least one of movement of a person through an access portal and a state of the access portal and a processing unit configured to receive the data points from the sensing device and to form activity clusters from the data points based upon similar patterns of inactive or active behaviors.
Claims19
An access monitoring and control system, comprising:
- a sensing device configured to collect data points regarding at least one of movement of a person through an access portal and a state of the access portal;
- and
- a processing unit configured to receive the data points from the sensing device, to organize the data points in time slots, and to form activity clusters from the data points based upon similar patterns of inactive or active behaviors during days of a week, wherein each day represents an instance in a data set and each time slot represents an attribute of the instance, wherein each of the data points of the activity clusters represent a cumulative inactive time, and wherein the processing unit is configured to group the days that have the most similar patterns to form the activity clusters.
A method of providing an access monitoring and control system, comprising:
- providing a sensing device for collecting data points regarding at least one of movement of a person through an access portal and a state of the access portal;
- and
- providing a processing unit to receive the data points from the sensing device, to organize the data points in time slots, and to form activity clusters from the data points based upon similar patterns of inactive or active behaviors during days of a week, wherein each day represents an instance in a data set and each time slot represents an attribute of the instance, wherein each of the data points of the activity clusters represent a cumulative inactive time, and wherein the processing unit is configured to group the days that have the most similar patterns to form the activity clusters.
A method of detecting an abnormal activity for an access control system, comprising:
- obtaining activity data from the access control system;
- grouping the obtained activity data into activity clusters, each activity cluster representing those days of a week having similar patterns of inactive or active behaviors;
- and
- evaluating new data points against the activity clusters to detect the abnormal activity.
