Embodiment Construction

[0013] Figure 1 illustrates a distributed authorization architecture with which an embodiment of the present invention may operate. As shown in the figure, the communication device 102 can communicate wirelessly with the authorization server 118 to initiate and confirm requests made by applications running on the communication device 102 to access the device specific data 110 . For example, communication device 102 may be or include a cellular telephone, a network wireless device such as a personal digital assistant (PDA) or personal information manager (PIM) equipped with an IEEE 802.11b or other wireless interface, a laptop computer or a wireless device equipped with an 802.11b or Other laptops with other wireless interfaces, or other communication or user equipment. The communication device 102 may communicate with the authorization server 118 via the antenna 112, eg, in the 800 / 900 MHz, 1.9 GHz, 2.4 GHz or other frequency bands, or through an optical or other link.

Abstract

According to the invention cellular telephones or other communications devices (102) may intercept requests (114) by applications (104), for instance applications received via over-the-air programming (OAP), to access sensitive device-specific data (110). That device-specific data (110) may include hardware identifiers such as IMEI or other serial or subscriber identification values, personalized settings such as phone books, contact lists, messaging or other information. The requests (114) by applications (104) for access to that type of data may be intercepted, for instance, by an application programming interface (106) executing on the communications device (102). The application programming interface (106) may communication the request (114), along with information identifying the requesting application, to a remote authorization server (118). The facility may compare the application identifier or other information against a list or table of applications authorized (120) to access device-specific data (110). A grant, denial, deferral or other determination may be communicated back to the device, to permit or deny access accordingly. The routing of requests (114) for such data to a remote host server (118) may, for example, prevent the accessing or corruption of sensitive data by viruses, rogue applications or other types of wireless intrusions.
