A method of managing profile information in a heterogeneous network of devices is described, including the steps of distributing a user profile among one or more devices in the form of a plurality of profile nodes and administrating read/write operations on the profile nodes according to a coherence protocol, the coherence protocol being adapted to dynamically allocate administrative rights over the profile nodes to the devices, and conditionally cache the profile nodes according to dynamically determined caching rights. Characteristics and/or changes in the structure of the network and/or the devices constituting the network can cause the profile to be dynamically replicated and distributed across the network so that specific profile information is coherent and accessible to corresponding devices in the network. The invention provides a means for securely storing profile data across a disparate network while ensuring coherence and secutiry. Such profile data can include user data reflecting context preferences such as browsing preferences, financial data, user data etc.
A method of managing profile information in a heterogeneous network of devices including the steps of:
A method as claimed in any preceding claim wherein characteristics and/or changes in the structure of the network and/or the devices constituting the network cause the profile to be dynamically replicated and distributed across the network so that specific profile information is coherent and accessible to corresponding devices in the network.
A method as claimed in any preceding claim wherein the read/write operations are adapted to conform to a write-invalidate protocol.
A method as claimed in any preceding claim wherein the administration is performed by a master device.
A method as claimed in any preceding claim wherein specific administrative rights for one or more specified profile nodes are dynamically allocated to a device whereby that device then manages access rights to the one or more specified profile nodes and the data contained therein.
A method as claimed in any preceding claim wherein for a profile node data request, the caching rights are determined according to:
A method as claimed in any preceding claim wherein the profile nodes include one more profile item and corresponding attributes.
A system of networked heterogeneous devices, incorporating a profile bank, including:
