A device and method for displaying security information to a user is provided. The present invention may include a security device configured to display a security information on a display surface. The security information may include at least one component having two images based on a splitting of its representation that are viewable from corresponding angles of view. The images may be fused into the representation of the at least one component by a visual system of the user looking at them at a reading distance causing the eyes of the user to look at the images from the corresponding angles of view. A corresponding method for displaying security information to a user is also provided.

Display of security information based on splitting into images viewable at a certain reading distance

A solution is proposed for controlling access to computing resources. A corresponding method comprises receiving and verifying an access request for accessing the computing resources by a secondary computing environment (isolated from the computing resources). A main computing environment (isolated from the secondary computing environment) detects an indication of a positive result of the verification of the access request; in response thereto, the main computing environment verifies an integrity condition of the secondary computing environment and then authorizes the secondary computing environment to access the computing resources accordingly. A computer program and a computer program product for performing the method are also proposed. Moreover, a system for implementing the method is proposed.

Control of access to computing resources implemented in isolated environments

A solution is proposed for performing authentications. A corresponding method comprises storing a verification string corresponding to applying a one-way function iteratively starting from a secret string. An authentication request is received in association with an authentication string (or more) being generated by applying the one-way function iteratively starting from the secret string for a lower number of times. A result of the authentication request is determined by comparing the verification string with a comparison string being generated by applying the one-way function to the authentication string (or a few times iteratively). Corresponding computer programs and a computer program products for performing the method are also proposed. Moreover, corresponding systems for implementing the method are proposed.

Authentication based on chain of strings generated from secret string

An evacuation system which maintains an active count of people in real time in a location, for example a building or other geographic area with defined boundaries and dynamically calculates the best path for a user or group of users to follow when an emergency situation occurs. The people in the location may be tracked by a user wearable RFID device and may classify the people based on specific needs or other criteria.

Optimal evacuation plans in emergency situations

Aspects provide for a printer with automatic paper sheet count discovery, via determining an initial weight of printer paper sheets within a printer paper feeder tray. A single sheet is removed from the paper feeder tray to a staging area of the printer, and a revised weight is determined for the sheets within the paper feeder tray while the single sheet of paper is removed to the staging area. The single sheet is fed back into the paper feeder tray via a printing path bypass of the printer. The weight of the single sheet determined as a function of the difference between the initial weight and the revised weight. A quantity of printer paper sheets currently loaded within the paper feeder tray and available to satisfy a print job is determined as equal to the initial weight divided by the weight of the single sheet.
