    摘要: A signal conditioning system for improving the analog signal-to-noise ratio. The system first filters (to reduce the extrinsic noise outside the bandpass), then squares (to reduce the intrinsic noise inside the bandpass), finally transforms the improved analog signal into a digital-like signal (using a threshold circuit) to interface with associated control logic in an ink jet droplet apparatus.

    摘要: A smart card, system, and method for securely authorizing a user or user device using the smart card is provided. The smart card is configured to provide, upon initialization or a request for authentication, a public key to the user input device such that the PIN or password entered by the user is encrypted before transmission to the smart card via a smart card reader. The smart card then decrypts the PIN or password to authorize the user. Preferably, the smart card is configured to provide both a public key and a nonce to the user input device, which then encrypts a concatenation or other combination of the nonce and the user-input PIN or password before transmission to the smart card. The smart card reader thus never receives a copy of the PIN or password in the clear, allowing the smart card to be used with untrusted smart card readers.

    摘要: A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. In the method a modified base image is overlaid with a modified overlay image on a display and at least one of the modified base image and modified overlay image is moved by the user. In addition to the moving, a change in orientation of at least one of the modified base image and the modified overlay image is required. Positive authentication is indicated in response to the base image reference point on the modified base image being aligned with the overlay image reference point on the modified overlay image after moving through at least one other pre-selected reference point.

    摘要: A system and method for processing certificates located in a certificate search. Certificates located in a certificate search are processed at a data server (e.g. a mobile data server) coupled to a computing device (e.g. a mobile device) to determine status data that can be used to indicate the status of those certificates to a user of the computing device, without having to download those certificates to the computing device in their entirety. The data server is further adapted to transmit the status data to the computing device. In one embodiment, at least one status property of the certificates is verified at the data server in determining the status data. In another embodiment, additional certificate data is determined and transmitted to the computing device, which can be used by the computing device to verify, at the computing device, at least one other status property of the certificates.

    摘要: A secure message that includes an attachment is received at a server. The secure message may have a secure layer that indicates that the secure message is at least digitally signed. The secure message may be provided without the attachment to the mobile device over a wireless network. A request may be received from the mobile device to access the attachment. The request may include an attachment identifier (ID) that identifies the attachment in accordance with a message-attachment indexing system. In response to the request to access the attachment, the server may perform an index lookup to find the attachment based upon the attachment ID, may look through the secure layer of the secure message in order to locate the attachment within the secure message, and may render at least an initial portion of the attachment by the server in a format for viewing by the mobile device.

    摘要: Responsive to intercepting an outbound command, a command interceptor may, upon determining that the command is associated with a particular category of commands, transmit an anticipatory response to the source of the command, for example, to prematurely indicate that the command has met with success. Accordingly, a given application whose further execution is dependent upon the successful completion of the command may further execute earlier than would be the case if the given application was to await the transmission of the command, the generation of a response indicating success and the receipt of the response indicating success.

    摘要: The present disclosure relates generally to the authentication of contactless payments attempted by a device having embedded contactless payment functionality. In particular, the disclosure is directed to systems and methods that utilize authentication schemes that already exist on a device in which the contactless payment functionality is embedded. One example of such authentication schemes is the use of password protection to lock or unlock the device in which the contactless payment functionality is embedded. Using the password protection functionality may provide varying levels of authentication protection based on the desires of the user. A number of exemplary uses of such a method and apparatus are disclosed herein.
