Abstract: A device for producing an output light emission having a light source for emitting light and a first polarizing beam splitter element positioned so at least one portion of the emitted light is incident thereupon, wherein a first reflected light beam of a first polarization state and a second transmitted light beam of a second polarization state are produced. The device also includes a first liquid crystal element having at least two states which are actuated using a control unit. The first liquid crystal element at least partially reflects the first light beam, wherein the polarization state of the first light beam is altered based on the state of the first liquid crystal element. The first polarizing beam splitter element is positioned so the first light beam is incident thereupon after reflection at the first liquid crystal element.

Abstract: A method and system for authenticating access of secure information by a user device. An authentication request for accessing the secure information is received, the authentication request including a user identifier of a user at the user device. A position of a secret quadrilateral within a first pattern of colored quadrilaterals is determined and is identifiable by the user identifier; the secret quadrilateral includes an authenticating color. The first pattern of colored quadrilaterals including the secret quadrilateral is generated. A second pattern including colored nodes that include the authenticating color at positions within a transparent authenticating card assigned to the user. The first pattern and the second pattern are sent to the user. Location information from the user device is received. It is determined that the subset of nodes that include the authenticating color, which allows access to the secure information by the user device.

Abstract: A method, system, and computer program product for authenticating an end user. A login field is generated and sent to an end user, and a set of nodes is subsequently received from the end user. The login field includes first colored nodes having multiple colors distributed in a first random pattern. A transparent credit card controlled by the end user includes second colored nodes having multiple colors distributed in a second random pattern. An authenticity status of the end user is determined, and then sent to the end user, by determining whether each node of the set of nodes (i) corresponds to a unique node of the first colored nodes and (ii) has a same color determined by a function of a static integer and a dynamic integer D, wherein S and D are known only to the end user and the provider of the transparent credit card.

Abstract: A method for authenticating an end user. The method begins by generating a login field in response to receiving an authentication request from an end user. The login field comprises a plurality of colored nodes containing a first subset of nodes matching both color and location to a second subset of nodes residing in a transparent credit card being controlled by the end user. Next the method determines the authenticity status of the end user by comparing data received from the end user with the first subset of nodes. The end user having generated the data by overlaying the transparent credit card on top of the login field and selecting at least one colored node. Each node being selected according to a function utilizing both static and dynamic variables. Finally, the method sends the determined authenticity status to the end user via an output device.

Abstract: A process for authenticating an end user. A first pattern of colored quadrilaterals is generated. A second pattern of multiple colored nodes that include a first subset of nodes is generated. The first and second patterns are sent to the end user. If a transparent credit card is overlaid by the end user on top of the second pattern, then a second subset of nodes in the credit card would match in color and location the first subset of nodes. The authenticity status of the end user is determined by determining whether each node of a third subset of nodes within the second subset of nodes (i) corresponds to a unique node of the multiple colored nodes and (ii) has a color that matches a specific color in one quadrilateral of the colored quadrilaterals. The determined authenticity status is sent to the end user via an output device.

Abstract: A method for authenticating an end user. The method begins by generating a login field in response to receiving an authentication request from an end user. The login field comprises a login node matrix comprising a first set of transparent and opaque nodes in addition to at least one login offset. Next the method determines an authenticity status of the end user by comparing data received from the end user with said first set of transparent nodes. The data received being sent in response to sending the login field to the end user. The end user generated the data by overlaying a transparent credit card on top of the login field and aligning the login offset with a card offset and then selecting at least one node which is not opaque. Finally, the method sends the determined authenticity status to the end user via an output device.

Abstract: A method of creating an electronic message from a sender to a recipient suggests a salutation. The method may search for the recipient in the sender's address book for an address book salutation, e-mail folders for an e-mail salutation, chat logs for a chat salutation, and/or organization directory for a hierarchical salutation. If the method finds at least one of the address book salutation, the e-mail salutation, the chat salutation, or the hierarchical salutation, the method suggests a salutation to the sender. If the method cannot determine the address book salutation, the e-mail salutation, the chat salutation, and the method attempts to deduce a name of the recipient. If the method fails to deduce the name of the recipient, the method suggests a default salutation. If the method deduces the name of the recipient, the method attempts to deduce a country of residence for the recipient.
