摘要： A proximity check ensures that a card is physically close to the reader device in order to inhibit relay attacks. The proximity check makes relay attacks more difficult because an additional channel must be intercepted and/or spoofed or relayed. This solution can be used for any kind of short-range communication, including Near Field Communications (NFC).

摘要： A method for motion estimation in video image data comprises a step of providing a block of pixels (B(F(t))) of a current image (F(t)) and a block of pixels (B(F(t−1))) of a previous image (F(t−1)) and a block of pixels (B(F(t−2))) of a pre-previous image (F(t−2)). A reconstructed block of pixels (B*(F(t), F(t−2),v)) is determined by combining the block of pixels of the previous image (B(F(t−1),v) and the block of pixels of the pre-previous image B(F(t−2),v)). A motion vector (v) of the block of pixels of the current image (B(F(t))) is evaluated by comparing the block of pixels of the current image (B(F(t))) with the reconstructed block of pixels (B*(F(t), F(t−2),v)).

摘要： An apparatus and method for performing FIR filtering and blending operations. A processor comprising: a decode unit to decode a packed N-tap finite impulse response (FIR) filter instruction, the packed N-tap FIR filter instruction to indicate one or more source packed data operands comprising a plurality of packed data elements, at least 3 filter coefficients, and a destination storage location, the plurality of packed data elements comprising data from a signal to be filtered and the plurality of filter coefficients specifying a filter function to be applied; and an execution unit comprising an FIR unit coupled with the decode unit, the FIR unit, in response to the packed N-tap FIR filter instruction being decoded by the decode unit, to perform at least N−1 multiplications to generate at least N−1 products, each of the multiplications comprising one of the filter coefficients multiplied by one of the packed data elements, the execution unit to combine the at least N−1 products in accordance with a specified type of FIR filter being implemented to generate a result packed data element to be stored in the destination storage location.

摘要： In one embodiment, an apparatus comprises an antenna to receive one or more radio signals, wherein the antenna is associated with a proximity-based access portal. The apparatus further comprises a processor to: detect, based on the one or more radio signals, an access request from a first device, wherein the access request comprises a request to access the proximity-based access portal using an access token associated with an authorized device; determine, based on the one or more radio signals, that the first device is within a particular proximity of the proximity-based access portal; obtain a first motion history associated with movement detected near the proximity-based access portal; obtain a second motion history associated with movement detected by the authorized device; and determine, based on the first motion history and the second motion history, whether the movement detected near the proximity-based access portal matches the movement detected by the authorized device.
