A method of determining a condition of a filter located within a system is provided. The method may include determining a first air flow measurement value for a first air flow through the filter, determining a first energy consumption value associated with generating the first air flow through the filter, determining a first ratio between the first air flow measurement value and the first energy consumption value, determining a second air flow measurement value for a second air flow through the filter, determining a second energy consumption value associated with generating the second air flow through the filter, and determining a second ratio between the second air flow measurement value and the second energy consumption value. The filter may then be replaced based on a comparison between the determined first and the determined second ratio.

A biometric authentication system includes an image database and a user database containing user profiles. Each user profile is associated with a selected image in the image database as an image key and with an ocular biometric data record obtained from an eye of the associated user. A user input terminal receives asserted user credentials, an eye scanning module obtains ocular biometric data, and a position detection module detects an eye position or eyelid position. An access control module communicates with the user database for obtaining a user profile associated with the asserted user credentials, communicates with a display device for displaying the image key associated with the obtained user profile, communicates with the position detection module for verifying the biometric authentication system by detecting whether the user is viewing the image key, and communicates with the eye scanning module for obtaining ocular biometric data and authenticating the user.

Ocular biometric authentication with system verification

A biometric user authentication method and computer program product includes receiving asserted user credentials from a user into a biometric authentication system, and obtaining a digitally-stored image key and ocular biometric data both associated with the asserted user credentials from memory within the biometric authentication system. The biometric authentication system is verified by simultaneously displaying the image key and at least one image other than the image key to the user and detecting that the user has selected the image key. The user is authenticated by scanning an eye of the user to obtain ocular biometric data and matching the scanned ocular biometric data to the digitally stored ocular biometric data. If the biometric system is verified and the user is authenticated, then the user is provided access to a protected area.

A method, system and computer program product for retaining trust. A computer receives a correct password for administrative access. The computer sets a trust to a maximum level. The computer detects at least one period of inactivity. The computer adjusts a trust based on the at least one period of inactivity. The computer receives a request to access an privileged function. The computer, responsive to receiving the request, determines that the trust is below a trust threshold. The computer, responsive to determining that the trust is below the trust threshold, challenges the user to authenticate. The computer receives a authentication attempt. The computer determines whether the authentication attempt is correct. The computer, responsive to a determination that the authentication attempt is correct, grants access to the administrative function.

Trust retention

In a method for accessing and storing original content without an overlay of interruption content, a computer receives original content with an overlay of interruption content during an interruption period from a content provider. The computer receives a notification that the interruption period is complete. The computer accesses original content without the overlay of interruption content. The computer stores the original content without the overlay of interruption content.

Accessing and storing original broadcast content

Methods, apparatuses, and computer program products for synchronously debugging a software program using a plurality of virtual machines are provided. Embodiments include controlling, by a master debugging module operating on a first virtual machine, execution of the software program within the first virtual machine; controlling, by a slave debugging module operating on a second virtual machine, execution of the software program within the second virtual machine including delaying execution of the software program within the second virtual machine relative to the execution of the software program within the first virtual machine; detecting, by the master debugging module, an error in the execution of the software program within the first virtual machine; and in response to the detection of the error, capturing, by a hypervisor, a snapshot of the second virtual machine.

Methods, apparatuses, and computer program products for load balancing servers are provided. Embodiments include determining, by a balance module, for each server within a rack comprising a plurality of servers, a vertical position of the server relative to the other servers within the rack; selecting from the plurality of servers, by the balance module, based on the determined vertical positions of the servers, a particular server to assign a workload; and assigning, by the balance module, the workload to the selected server.
