    13 URI Services Overview</title><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p>Mobile widgets are increasingly being used to connect to internet, which

    15 has increased the vulnerability of devices. To address this issue, Symbian

    16 provides a framework using which origins of harmful messages can be added

    17 to a BlackList. The framework also supports adding the origin of trusted clients

    18 to a WhiteList. This allows end users to control the data they receive from

    19 networks. </p>

    20 <p>Symbian provides a client-server framework to support BlackList/WhiteList

    21 origins (URIs). The framework currently supports <i>Browser</i>, <i>WapPush</i>, <i>PushEmail</i> and <i>DeviceProvisioning</i> service

    22 type URIs. The URI entry is unique for a given service type and similar URIs

    23 from different service types can exist in the URI list. </p>

    24 <p>The BlackList/WhiteList framework provides support for adding a URI to

    25 the list, removing a URI from list, updating a URI in the list, reading URIs

    26 from the list, and querying for URIs in the list. Support for wildcard URI

    27 entries is not provided. The framework also provides support for pre-configuration

    28 of URIs in the list to enable clients to add their own URIs. </p>
