A method for preventing password theft through unauthorized keylogging includes detecting, from a host application, a request for a password input by a user of an input keyboard device; activating a randomly generated keyboard map uniquely associated with the host application such that a first set of keystroke values inputted by the user results in a second, converted set of keystroke values transmitted to the host application, in accordance with the randomly generated keyboard map uniquely associated therewith; and upon completion of a password entry process by the user, deactivating the randomly generated keyboard map such that subsequent keystroke values inputted by the user are no longer converted to the values according to the keyboard map.

A password, unknown to a user to be authenticated by the password, is created by comparing an image provided by the user to a master image. Random differences between the images are found and used to create the password. The password is then validated to determine whether the user is authorized and/or to determine whether a communication provided by the user is to be processed.

A method of testing an integrated circuit. The method includes selecting a set of physical features of nets and devices of the integrated circuit, the integrated circuit having pattern input points and pattern observation points connected by the nets, each of the nets defined by an input point and all fan out paths to (i) input points of other nets of the nets or (ii) to the pattern observation points; selecting a measurement unit for each feature of the set of features; assigning a weight to each segment of each fan out path based on a number of the measurement units of the feature in each segment of each fan out path of each of the nets; and generating a set of test patterns optimized for test-coverage and cost based on the weights assigned to each segment of each of the nets of the integrated circuit.

A method and system for allowing the purchaser of an on-demand entertainment session of predetermined time duration to reaccess that portion of the session not used. On-demand passenger entertainment services in airline flights often offer services, such as movies, of a predetermined time duration which time is longer than the time of flight. The method and system disclosed allows purchasers to gain access on another flight to the unused portion of the services, such as, the unseen portion of a movie, terminated at the end of the initial flight.

A password protected machine where a primary alternative password and a secondary alternative password are assigned, but the secondary alternative password cannot be used to gain access unless and until the primary alternative password has been deactivated. Also, a password protected machine where a user is assigned at least two alternative passwords, and where the use of one alternative password will automatically deactivate the other password. Preferably, there is a primary password and a secondary password such that: (i) the use of the primary password does not deactivate the secondary password, but (ii) the use of the secondary password does deactivate the primary password.

A rules driven multiple passwords system is provided wherein a list of stored passwords are used in rotation over time in accordance with a set of rules or conditions managed by the system. With such an arrangement, the currently active password of a system User may automatically be changed, in accordance with the rules or conditions, to the next password in the list. The User is notified as to the newly assigned password.

摘要:
Monitoring text input from a keyboard and from a pointing device, is done by monitoring input from a user keyboard for entry of text and cursor controls; monitoring input from a pointing device; logging keyboard entered text to a key log; and responsive to input selectively from the pointing device and keyboard selectively signaling a command action, determining text contents of the command action and logging the text contents to the key log in sequence with the keyboard entered text. A temporary storage is provided for storing copied content, and for storing pointing device input device definitions and key command definitions for each application. A log file stores a key log table for each application; and a key logger stores to the key log table entered text reconstructed with reference to the pointing device position, the copied content, the pointing device input device definitions, and the key command definitions.

A system for implementing dynamic pseudorandom keyboard remapping includes a keyboard in communication with an operating system of a computing device; the keyboard configured to encrypt an original keyboard scan code corresponding to each of a plurality of keyboard keys, using a mapping algorithm, wherein the mapping algorithm encrypts the original keyboard scan code by using both the original keyboard scan code and a current one of a sequence of pseudorandom numbers generated using a pseudorandom number generator (PRNG) algorithm and an initial seed value; and the operating system configured to decrypt the original keyboard scan code based on an encrypted scan code generated and transmitted from the keyboard thereto, responsive to a keystroke of the keyboard, wherein the operating system also uses the mapping algorithm, the PRNG algorithm, and the initial seed value.
