Abstract: A process may be utilized for securing unlock password generation and distribution. A first set of exclusive responsibilities, assigned to a trusted authority, includes random generation and encryption of an unlock password to compose a randomly generated encrypted unlock password. Further, a second set of exclusive responsibilities, assigned to a security agent, includes sending information associated with the unlock password and a digital signature of information associated with the unlock password to a communication device configured for a network in order to mate the unlock password to the communication device, and sending the randomly generated and encrypted unlock password along with mating data to a password processing center. In addition, a third set of exclusive responsibilities, assigned to a password processing center, includes decrypting the randomly generated and encrypted unlock password.

Abstract: An apparatus (100) used by a plurality of devices to authenticate an accessory (120) is configured to operate with a device (110) of the plurality of devices. The accessory (120) applies an authentication algorithm to a key and a challenge (130) received from the device (110) and generates a response (132) thereto. A challenge and response memory (114) stores a subset of a set of challenges (232) and pre-computed responses (230). The enabling circuit transmits a challenge (130) to the accessory (120) and receives a received response (132) therefrom. The enabling circuit (112) also compares the received response (132) to the stored response (230) corresponding to the stored challenge (232) sent to the accessory (120).

Abstract: A method for controlling subsidy locking of a handset device includes storing, in a handset device, an asymmetrically digitally signed subsidy unlock data block that has been modified based on a password after signing (505); modifying the stored unlock data block based on a received subsidy unlock password (510); and granting subsidy unlock status if the asymmetric digital signature of the modified, stored unlock data block properly verifies (510). A method (110) for controlling subsidy locking of a handset device includes storing, in the handset device, an asymmetrically digitally signed subsidy unlock data block that comprises a password portion that has been modified after signing (112); replacing the contents of the modified password portion with a received subsidy unlock password to produce an updated subsidy unlock data block (116); and granting subsidy unlock status if the asymmetric digital signature of the updated subsidy unlock data block properly verifies (118).

Abstract: A method in a communication device (106) comprises registering (202) on a first network (102), identified by a first network ID, stored in the communication device. Then receiving, from the service provider, an acting network ID which identifies a second network (104). Storing the acting network ID on the communication device and reprioritizing the second network, identified by the received acting network ID, as the home network. The communication device then registers on the second network in response to the reprioritizing the second network.

Abstract: A method for proximity payment provisioning by a wireless communication device is disclosed. A photo image of a user of the wireless communication device is loaded. The loaded photo image is transmitted to a trusted party via a communication network. A superimposed photo image is received from the trusted party, wherein the photo image is superimposed with a watermark. The received superimposed photo image is stored in a memory.

Abstract: A method for proximity payment transaction between a wireless purchasing device and a point of sale terminal in conjunction with a trusted party. The wireless communication device initiates a proximity payment application for a transaction between the wireless purchasing device and the point of sale terminal. The wireless communication device transmits the first authentication code to the point of sale terminal. A first code is inputted at the point of sale terminal as a watermark on the superimposed photo image of the user, wherein the superimposed photo image is displayed on the wireless purchasing device. The point of sale terminal transmits a first code and the first authentication code to the trusted party via a second communication network. The point of sale terminal receives an approval message from the trusted party for approving the transaction between the wireless purchasing device and the point of sale terminal.

Abstract: A method (300, 400) to provide for provisioning and a product. In one embodiment a processor (210) receives a pre-configured data image and writes it to a first area (221) of non-volatile memory (220) using, for example a first writing mode. Thereafter, for example after a power cycle the processor (210) determines whether an update to a second area of the non-volatile memory is required, and if so converts a first data item from the first area into a second data item uniquely associated with the product unit and writes the second data item in a second area (222) using a second writing mode.
