A location service for wireless devices is described. In embodiments, a connection identifier is received that indicates a wireless device is linked to a communication node for wireless communication. Additional wireless devices are also linked to the communication node for wireless communication, and the additional wireless devices can each identify its geographic location. Location data is received from the additional wireless devices, where the location data indicates the respective geographic locations of the additional wireless devices. A location of the communication node can be determined from the location data that is received from the additional wireless devices, and a current location can then be assigned to the wireless device based on the determined location of the communication node.

A system and method are described for securing over the air communications between a service and a communication device. For example, one embodiment of a method for creating a security token on a communication device for communication between the communication device and a service includes combining a device identification of the communication device with a device capability to create a device information, the device capability known by the service. The method further includes encrypting the device information.

An system for allowing a computer network site to recognize an anonymous user without revealing the identity of the user. The system involves generating a user alias based on the user's identity and the computer network site such that it is computationally difficult to determine the user's identity from the alias alone. The system further involves informing the computer network site of the alias upon access of the site by the user. The computer network site may then block access to the site's contents whenever it receives an alias associated with a disruptive user.

A technique is provided for creating an autonomous network entity that stores sensitive information in a cryptographically secure manner. The autonomous entity comprises a data structure that encapsulates cryptographically-transformed information along with the inputs of a secret key used to reverse the transformation. Cryptographic storage of the sensitive information and its reversable key within the encapsulated entity makes the entity autonomous and capable of transfer among computer platforms and their processes without compromising the security of the information.

A digitally signed message, protected with a chain of certificates from the sender's immediate certifier up through an ultimate certifier, is transmitted to a recipient together with the entire certificate chain. The entire certificate chain is stored in a single signer file accessible by the sender. Drag-and-drop gestures of a graphical user interface are used by the sender to sign and certify the message, and an icon is provided on the recipient's display to initiate verification.

Message protection mechanism and graphical user interface therefor

A method for 5-bit chunk encoding of bit serial data by a data processor handling data in 8-bit byte segments, the method comprising the steps of: setting a bit shift counter (bsc) to zero; receiving data from the bit serial data to be stored into 8-bit bytes, such that at least two 8-bit bytes are available, the bit serial data stored in the 8-bit bytes from the most-significant bit to least significant bit; shifting left the data in the first byte, by the value of the bsc; encoding the data contained in the first two bytes in two 5-bit chunks; incrementing the bsc by an increment of 2, and if the bsc is then equal to 8, resetting it to zero; offsetting the data to the next whole byte boundary of the 8-bit byte data, dropping already processed bytes; and so long as there is data, repeating the steps of receiving, shifting, incrementing, and offsetting.
