Abstract: A system and method for wireless cryptographic key exchange among participants in a wireless computing network is presented. This allows the authorized participants in the wireless communication session not have the same key before the wireless computing session begins. This wireless online key exchange/generation is based on a random modulation technique and a domino match. Once the initial modulation scheme is selected, each data transmission includes an indication of what modulation scheme should be used for the next data transmission. If a given number of bits are to be used, the modulation scheme for the final transmission may be limited to complete the bit transfer. The bit value assignments within particular modulation schemes may also be varied for each subsequent transmission.

Abstract: A valid medium issuing system reads a key Ka corresponding to an ID number from a key management book at a request from the script storage system to issue a script medium (MO), decrypts a valid medium certificate in a storage medium delivered from the factory using a key Ka, and generates a script medium (MO). The script medium (MO) is transmitted to the script storage system, and the script storage system records a script document on the script medium (MO). In this process, a decrypting process of a valid medium certificate is performed using the same key Ka, and after confirming the script of the storage medium, the script is recorded. With this configuration, a script document is recorded only for the script.

Abstract: Secret information is shared by a group of members by giving each member a first share of the information. To reconstruct the secret information, a subgroup consisting of some or all of the members generate second shares from their first shares, and distribute the second shares to the other members of the subgroup. Each member of the subgroup performs an operation on the second shares it receives and one second share it generated itself to obtain an intermediate result. The intermediate results are transmitted to one or more members of the subgroup, or to a central facility, where the original secret information is obtained from a further operation performed on the intermediate results. The original secret information can thereby be obtained without compromising the secrecy of the first shares, and without forcing the members to reveal their identities.

Abstract: Application servers are programmed such that when an application server changes a compromised service key, the compromised key is saved by the application server until all tickets that may have been issued under the compromised key expire. Whenever the application server receives a ticket from a client issued under the compromised key, it generates an authenticator for an error message using the session key extracted from the ticket and sends the error message with this authenticator to the client. Clients are programmed to be able to receive error messages from application servers that have changed their service keys. Because the error messages include an authenticator generated by the application server using the session key extracted from the compromised ticket, the client is able to rely on the error message. The client is able to automatically request a new ticket from a key distribution center in response to a successful authentication of the error message.

Abstract: A checkpoint screening system uses multiple cameras to provide images at different angles of a person to be screened. Different features extracted from the images at different angles are compared to a profile associated with the person to be screened. In one embodiment, the person first provides an ID, such as a drivers license or other identification, and the profile is retrieved. If a match is detected, the person may continue through the checkpoint. If no match is detected, the person may be directed to a different path through the checkpoint for further verification of identity. A registration process is used to enroll members and obtain a member profile. Three camera angles are utilized to provide a three dimensional image. Each image is independently compared against the profile and the decisions from such comparisons are weighted. The profile is regressively updated and weighted if a match is detected.

Motion from multiple background image regions are combined to measure the global motion in that image frame. The measured global motion in the object image regions are compensated to measure local motion of the object and the local motion of the object is tracked.

Abstract: A system and method for localizing imaging devices in a network using images taken by the imaging devices. The relative position and orientation of a network of camera-equipped communications devices are obtained by having each device examine images taken by its camera.

This variation is found in images and used to identify the devices in view and to define epipolar points related to the other imaging devices in view. Common reference points in the image are also identified. The imaging devices then exchange details of the epipolar and common reference points with each other, and use them to obtain their relative position and orientation.

The techniques include receiving a training set that includes positive images and negative images, receiving a restricted set of linear operators, and using a boosting process to train a classifier to discriminate between the positive and negative images. The boosting process is an iterative process. The iterations include a first iteration where a classifier is trained by (1) testing some, but not all linear operators in the restricted set against a weighted version of the training set, (2) selecting for use by the classifier the linear operator with the lowest error rate, and (3) generating a re-weighted version of the training set. The iterations also include subsequent iterations during which another classifier is trained by repeating steps (1), (2), and (3), but using in step (1) the re-weighted version of the training set generated during a previous iteration.

Abstract: A system and process for creating an interactive digital image, which allows a viewer to interact with a displayed image so as to change it with regard to a desired effect, such as exposure, focus or color, among others. An interactive image includes representative images which depict a scene with some image parameter varying between them. The interactive image also includes an index image, whose pixels each identify the representative image that exhibits the desired effect related to the varied image parameter at a corresponding pixel location. For example, a pixel of the index image might identify the representative image having a correspondingly-located pixel that depicts a portion of the scene at the sharpest focus. One primary form of interaction involves selecting a pixel of a displayed image whereupon the representative image identified in the index image at a corresponding pixel location is displayed in lieu of the currently displayed image.

If multiple feasible placement locations are identified for a particular scale factor, then one is selected based upon predetermined criteria. The object can then be inserted into the container region and the resulting composite image stored or, alternatively, parameters can be stored which enable object insertion at a subsequent processing step.

Abstract: Deformable models are used for the segmentation of structures in 3D images. The basic principle of such methods consists of the adaptation of flexible meshes to the image. However, the simultaneous segmentation of multiple or composed objects often causes problems in that spatial relationships between the objects are violated, or that meshes are intersecting each other. According to the present invention, a priori knowledge about spatial relationships between objects is introduced into the shaped model. This allows to maintain spatial relationships between the objects and to avoid intersecting meshes.
