Method of assessing real-time security of sequenced packet exchange (SPX) network connection
A method of assessing the security of a user's connection to a Sequenced Packet Exchange (SPX) network and the user's consumption of services via the SPX network. The invention includes digitally accessing a plurality of network nodes and obtaining data transmissions through said plurality of network nodes. Each transmission corresponds to a security implementation of a current state of the user's connection or consumption of SPX services. A coefficient is determined for each security implementation, wherein the coefficient corresponds to a weight given to each security implementation in determining a level of security of the user's connection or consumption. A security score representative of the level of security of the user's connection is calculated as a function of the security implementation and their corresponding coefficients. The security score is output to the user. |

Dynamic watch-based CAPTCHA
Techniques are disclosed for implementing a CAPTCHA access control system based on graphical representations of a watch or other timekeeping device. More particularly, the disclosed CAPTCHA system's request/challenge mechanism employs a graphical representation of a watch whose perturbation from a baseline visual presentation is controlled by a large number of attributes, each of which may assume a number of different values. The use of a large number of display attributes (e.g., 20 or more) and a relatively small number of difficulty levels allows each difficulty level to have an enormous number of possible graphical representation. Such a large number of potential challenge images essentially precludes the likelihood that any automated search for a matching image—providing the ability to correctly respond with certainty to the challenge query—will be successful. |

Non RFC-compliant protocol classification based on real use
A firewall system determines whether a protocol used by an incoming data packet is a standard protocol compliant with Request For Comment (RFC) standards. In the event the protocol is RFC compliant, the firewall transmits the packet to the recipient according to firewall policies regarding the standard protocol. If the protocol is not that of an RFC standard, the firewall determines whether the protocol matches an RFC-exception protocol in a RFC-exception protocol database. If the protocol does match an RFC-exception, the firewall may transmit the packet to the recipient according to firewall policies regarding the RFC-exception protocol. If it does not match an RFC-exception, the firewall may transmit the packet or protocol to a support system where it may be quarantined until it is approved based on a decision that the protocol is safe and/or widely adopted. |

Semiconductor device, display device, and electronic appliance
In case the size of the transistor is enlarged, power consumption of the transistor is increased. Thus, the present invention provides a display device capable of preventing a current from flowing to a display element in signal writing operation without varying potentials of power source lines for supplying a current to the display element per row. In setting a gate-source voltage of a transistor by applying a predetermined current to the transistor, a potential of a gate terminal of the transistor is adjusted so as to prevent a current from flowing to a load connected to a source terminal of the transistor. Therefore, a potential of a wire connected to the gate terminal of the transistor is differentiated from a potential of a wire connected to a drain terminal of the transistor. |

Via configuration for wafer-to-wafer interconnection
A modification to the standard layout of vias used for vertically-stacked wafer bonding is proposed which has been found to improve the interconnect overlay while avoiding the dishing problems associated with the planarization processes used in the creation of conductive posts within the vias. In particular, the pitch, i.e. the spacing between adjacent posts, is intentionally chosen to be different for each wafer. By using different pitches, there is an increase in the probability of overlap of posts on each wafer, even when one wafer is slightly offset with respect to the other (which is possible when aligning one wafer with another in a standard bonding tool). Advantageously, the use of different pitches allows for the use of relatively small diameter (one micron or less) posts while still creating sufficient overlap for the necessary connections. |

The image processing application can generate a face mesh that includes landmark points, and then construct the deformation fields on the face mesh, where the deformation fields are defined by warpable elements formed from the landmark points. The image processing application can also combine the deformation fields. The image processing application can also receive an input to initiate modifying one or more of the facial features of the face in the image using the combined deformation fields. |

Method of and apparatus for processing a frame
A method of processing a frame in a data processing system is provided, in which the frame comprises one or more frame regions that together form the frame, and each frame region is represented as one or more data values, with each data value being represented by a set of data. The method comprises, for at least one region of the frame, when a memory access operation is to be performed for the region of the frame, comparing (163) a portion of the data representing data values for the frame region (165) with a corresponding portion of the data representing the corresponding data values for a previous frame region (162), which is a frame region for which the memory access operation has been performed, to determine if the portion of the data representing the data values for the frame region is similar to the corresponding portion of the data representing the data values for the previous frame region, wherein the portion of the data representing the data values for a frame region comprises a sub-set of controller data (167a, 167b) from each set of data representing a data value of the data values for the frame region. In an embodiment, if the portion of the data representing the data values for the frame region is determined to be similar to the corresponding portion of the data representing the data values for the previous frame region, the memory access operation is omitted, or, if the portion of the data representing the data values for the frame region is determined not to be similar to the corresponding portion of the data representing the data values for the previous frame region, the memory access operation is performed (169). |

Graphics pipeline method and apparatus
Provided are a graphics pipeline method and apparatus. For each of plural screen pixels, locations of one or more sampling are determined based on a set pattern to modify an image to be rendered. A pixel corresponding to a set primitive is generated at a determined location of a sampling point, of the one or more sampling points. The image is rendered using the generated pixel. |

Electronic message redacting
A mechanism is provided for controlling the content of an electronic message on an electronic messaging system including a plurality of communities that facilitates the tailoring of the content of a posted electronic message to the interests and/or access privileges of such communities. An electronic lexicon is provided for each community, the lexicon defining content relevant to the community. The electronic message is interpreted for disclosure to a particular community to identify content in the message relating to content in the electronic lexicon of the particular community. The electronic message is redacted based on the identified related content if the electronic message contains content in a form unsuitable for the disclosure. |

Personal financial planning and engagement with peer-based comparison
A computer-implemented method for setting and tracking financial goals includes retrieving account information associated with a financial account of a user. The method also includes providing to the user via a user interface, prospective financial goals. The method further includes receiving from the user via the user interface, a selection of one of the financial goals. Further yet, the method includes monitoring the user's account information to track the user's progress towards the selected financial goal. In addition, the method includes providing to the user via the user interface, based on the monitoring of the user's account information, no more than three suggested actions to improve the user's progress towards the selected financial goal. |
