Abstract: Disclosed is a method for anonymizing location information of a mobile device 110 comprising: providing a trusted edge server 202 at a network edge; the mobile device intercepting a request for access to location information made by an application and redirecting the request 310 to the trusted server; the trusted server obfuscating the location information, based on the location other mobile devices proximal to the querying mobile device to generate an obfuscated location information, the other mobile devices being selected based on a similarity between user profiles associated with the mobile device and the other mobile devices; the trusted server returning 312 the obfuscated location information to the mobile device which then sends 314 the obfuscated location information to the application. The mobile device may submit a category from its user profile to the trusted server, which may identify the other mobile devices with a preference in the category the same as that of the mobile device. Categories other than those for which a preference has been specified may be used to determine which other mobile devices are selected. A desired level of anonymity may be provided by an end user, with the trusted server obfuscating the location information such that this level is achieved.

Abstract: A method for indicating the trustworthiness of data processed in accordance with a processing rule whereby a first trust weight is assigned to a data item to be processed to provide a weighted data item, the first trust weight representing a level of trust in the data item, and second trust weight is assigned to the processing rule to provide a weighted processing rule, the second trust weight representing a level of trust in the processing rule. The weighted data item is processed in accordance with the weighted processing rule to generate a data output and an indication of a level of trust in the data output.
