摘要： In one aspect there is provided a computer-implemented method for encrypting a data element. The method includes generating a symmetric key and encrypting the data element using the symmetric key. The method also includes identifying one or more entities in a policy database that are authorized to access the data element, and retrieving a public key associated with each of the one or more entities. The method also includes, for each entity of the entities that are authorized to access the data element, encrypting the symmetric key using the public key associated with the entity to obtain an encrypted symmetric key, and appending the encrypted symmetric key to a file storing the encrypted data element.

摘要： Systems and methods are provided for matching one or more first entities with one or more of second entities. Factor graph representations of the first entities and a plurality of second entities are stored. The factor graph representation of the plurality of second entities includes an identity variable referencing each of the individual second entities. When a request is received from a requesting one of the first set of entities for a match from the second set of entities, the first factor graph and the second factor graph are merged, and the merged graph is solved for a probability mass function for the identity variable to yield a probability vector to be used to identify those ones of the plurality of second entities having the highest probabilities as matches to be returned in response to the request.

摘要： A system and method for speed measurement of a mobile device, using an speed sensor such as a satellite navigation system or an accelerometer, does not need such speed sensor to be continually activated. The system and method make use of a monitor for monitoring at least one motion indicium for indicating that the speed of the mobile device is above an initial threshold, including but not limited to: monitoring the Doppler shift measurements of a timing signal; monitoring the timing advance of a cellular radio signal; monitoring the number of base stations visible to the mobile device; monitoring the frequency of base station handover, however determined; monitoring the level crossings and/or the autocorrelation of an RSSI signal; and/or triangulation of the position of the mobile device. When the monitor determines that the mobile device may be travelling in excess of a threshold speed, a speed sensor is activated to confirm the indication. If the speed sensor determines that the mobile device is travelling at a speed below a second threshold, the speed sensor is deactivated.

摘要： A speed parameter or channel quality parameter are determined in a mobile device based on variation in frequency offset measurement. A higher variation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the frequency offset measurement reflects a better channel quality and a lower speed. The parameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.
