Abstract: Example methods, apparatus and articles of manufacture to process cardiac images to detect heart motion abnormalities are disclosed. A disclosed example method includes using a filter coefficient based on a plurality of cardiac images to characterize motion of a heart; computing an information-theoretic metric from the filter coefficient; and comparing the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal.

Abstract: A method for securing data uses a unitary device to obtain a biometric reading from a user, and to generate a new key pair corresponding to the user's biometrics. The unitary device uses a private key from the key pair to encrypt data or voice, sends the encrypted data or voice to a second device and deletes the private key. The unitary device can authenticate the user using a previously generated public key corresponding to the user's biometrics. Also, the second device can decrypt the received data or voice using a public key corresponding to the user and previously received from the unitary device.

Abstract: A method for identifying a remote client device and sending a transaction to that remote client device. The method enables mobile payment, mobile signing as well as mobile ID.

Abstract: A method for adapting a mobile identity involves an application publishing different attributes when the application is in the foreground, is in a know location or is in proximity of a beacon then when it is not. The attributes can be scanned wirelessly using short wireless communication.

Abstract: Methods and apparatus are disclosed to label radiology images. An example system includes a processor and a database. In response to receiving a first user input via a data input, the processor is to generate first annotations on a spinal image. The processor is to cause the spinal image having the first annotations to be displayed at a user interface. The processor is to prompt a user to provide second user input identifying an error in the first annotations. In response to receiving the second user input, the processor is to generate second annotations on the spinal image. The second annotations is to correct the error in the first annotations.

Abstract: A method for facilitating login using adaptive authentication. The method uses different authentication methods and different data protection methods depending on the user location, availability of network, importance of the data.

Abstract: A method for facilitating authentication enables to automatically log the user to an application multiple times as long as the user has not left proximity of the terminal since the last successful login.

Abstract: Methods and apparatus are disclosed to automatically detect vertebrae boundaries in a spine image. A method to detect a vertebra in a spine image is described, the method comprising generating a rectangle approximation of a reference vertebra. The method also including identifying a mask similar to the rectangle approximation and labeling a mask region in the mask. The method also including comparing the mask region to the rectangle approximation and detecting a vertebra in the spine image based on the comparison.

Abstract: A method for automatically updating access security on existing applications with multi-factor authentication, intelligent auto-login, single sign-on, proximity logout, pro-active loss prevention and real-time incident notification using a wrapping function.

Abstract: A method and apparatus for mobile security using a short wireless device. The method and device increases mobile device security and data security and reduces false alerts.

Abstract: Example methods, apparatus and articles of manufacture to process cardiac images to detect heart motion abnormalities are disclosed. A disclosed example method includes using a filter coefficient based on a plurality of cardiac images to characterize motion of a heart; computing an information-theoretic metric from the filter coefficient; and comparing the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal.

Abstract: A method and apparatus for intelligent authentication based on proximity and using a short wireless device. The method checks if the user captured a PIN code recently and if no signal drop was detected since the last PIN capture. It obtains user data from a unitary short wireless device and authenticates it. If the user PIN was not captured recently, or if a signal drop was recently detected, the user is asked to enter a PIN code.

Abstract: Example methods, apparatus and articles of manufacture to process cardiac images to detect heart motion abnormalities are disclosed. A disclosed example method includes adapting a state of a state-space model based on a plurality of cardiac images to characterize motion of a heart, computing an information-theoretic metric from the state of the state-space model, and comparing the information-theoretic metric to a threshold to determine whether the motion of the heart is abnormal.

Abstract: A method and apparatus for securing user data on a mobile device using a Bluetooth fob. The method and apparatus enables robust access security, issues alerts when the user leaves proximity of his/her terminal, and can delete confidential data. The method also teaches using a Bluetooth smart phone soft token for securing data on a mobile device.

Abstract: A system includes a central program store location having a memory storing a plurality of access keys and programs. A communication network connects the program store location and a host system. A communication channel connects the host system and a target system. The program store a first program and a second program to the host system. The host system then tries to download the second program to the target system. If the target system authenticates the second program signatures and/or keys, the second program and/or keys is downloaded. The first program and the second program enable the host system and the target system to exchange information.

Abstract: A method and apparatus for three-factor authentication uses a short wireless device to authenticate access to a computer or device. The computer or device issues a challenge question to the user, for example, requesting the user to say a phrase or write symbols. The user biometric information is captured and authenticated using the short wireless device.

Abstract: Disclosed are adaptive loop filtering techniques for video encoding and/or decoding. For a video unit, the encoder selects a set of predefined filters or generates a set of new filters, and places into the bitstream information identifying the set of predefined filters, or information defining the set of new filters. The set of filters may be used for loop filtering of at least one of the reconstructed samples of the video unit. At the decoder, a set of filters may be obtained by, decoding an index that identifies a set of predefined filters, or by decoding information related to a set of new filters. The obtained set of filters may be used for loop filtering of at least one decoded and reconstructed sample of the video unit.

Abstract: Disclosed are adaptive loop filtering techniques in the context of video encoding and/or decoding. For each video unit, the encoder can select a filter shape, and can place into the bitstream information that identifies the filter shape. At least one filter whose shape is the selected filter shape is used to loop filter at least one sample. At the decoder, a filter shape is obtained by decoding information that identifies the filter shape. At least one filter whose shape is the obtained filter shape is used to loop filter at least one reconstructed sample. Different filter shapes are also disclosed.
