A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Secure data parser method and system

A communication system includes a plurality of recipient processors (14, 15, 16) located at geographically remote locations with respect to each other and connected for communication with an information provider processor (12), over the communications network. The provider (12) and recipient processors (14, 15, 16) may comprise respective computers coupled for communication on the Internet or WWW. The provider processor is capable of providing information from any suitable source, by communicating such information over a communications network. However, access to the information by the recipient processors is controlled, based on the geographic location or region of the recipient processors. Each recipient processor is operably associated with a positioning system for providing geographic location information corresponding to the location or region in which the positioning system is located, such as a global positioning system GPS (20, 21, 22). The geographic position information is used to determine whether or not the processor requesting the information is within a restricted or non-restricted region.

System and process for limiting distribution of information on a communication network based on geographic location

A method for location discovery in a data network includes receiving, at a first device, connection information from a neighboring network device and determining a physical location of the first device based on the connection information. The method can include receiving, at the first device, the physical location transmitted from the neighboring network device. The method can further include associating a level of trust with the physical location based on the neighboring network device. The first device be one of a variety of devices, such as a router, a switch, a network entry device, a firewall device, or a gateway.

Location discovery in a data network

A system that associates physical locations with network-linked devices in a network to which such devices are connected. This system employs a variety of techniques for establishing device location. The system configuration can vary and can include any type of data network, including LANs, MANs, Wide Area Networks (WANs), Personal Area Networks (PANs), and Home Networks. The system provides location information for particular devices to the network devices and management, and may be used in any of a variety of ways to improve configuration accuracy, control, and security. The location information may also be used to control or secure a device itself.

Locating devices in a data network

A computing device to enable a feature thereof according to a current location and a control method thereof, the computing device including: a location unit to determine the current location of the computing device; and a licensing unit to determine whether the current location corresponds to a predetermined authorized location, and to enable the feature if the current location corresponds to the authorized location. Accordingly, a permission to use a software feature or a hardware feature of the computing device can be controlled according to the current location of the computing device.

Access to digital data is controlled by encrypting the data in such a manner that, in a single digital data acquisition step, it can be decrypted only at a specified location, within a specific time frame, and with a secret key. Data encrypted in such a manner is said to be geo-encrypted. This geo-encryption process comprises a method in which plaintext data is first encrypted using a data encrypting key that is generated at the time of encryption. The data encrypting key is then encrypted (or locked) using a key encrypting key and information derived from the location of the intended receiver. The encrypted data encrypting key is then transmitted to the receiver along with the ciphertext data. The receiver both must be at the correct location and must have a copy of the corresponding key decrypting key in order to derive the location information and decrypt the data encrypting key. After the data encrypting key is decrypted (or unlocked), it is used to decrypt the ciphertext. If an attempt is made to decrypt the data encrypting key at an incorrect location or using an incorrect secret key, the decryption will fail. If the sender so elects, access to digital data also can be controlled by encrypting it in such a manner that it must traverse a specific route from the sender to the recipient in order to enable decryption of the data. Key management can be handled using either private-key or public-key cryptography. If private-key cryptography is used, the sender can manage the secret key decrypting keys required for decryption in a secure manner that is transparent to the recipient. As a consequence of its ability to manipulate the secret keys, the sender of encrypted data retains the ability to control access to its plaintext even after its initial transmission.

System and method for delivering encrypted information in a communication network using location identity and key tables

A method and apparatus for controlling access to digital information utilizes a location identity attribute that defines a specific geographic location. The location identity attribute is associated with the digital information such that the digital information can be accessed only at the specific geographic location. The location identity attribute further includes a location value and a proximity value. The location value corresponds to a location of an intended recipient appliance of the digital information, and may be further defined in terms of latitude, longitude and altitude dimensions. The location identity attribute is enforced by allowing access to the digital information only at the specific geographic location. As a first part of this enforcement process, the location of an appliance through which access to the digital information is sought is identified. The appliance location is then compared to the specific geographic location defined by the location identity attribute, and access to the digital information is allowed only if the appliance location falls within the specific geographic location. There are many ways to identity the location of the appliance, including: (1) resolving the appliance location from a street address for the appliance; (2) retrieving the appliance location from a file stored within the appliance; (3) recovering the appliance location from a GPS receiver embedded in the appliance; and (4) recovering the appliance location by triangulating RF signals received by the appliance.

System and method for using location identity to control access to digital information

A method and apparatus for controlling access to digital information utilizes a location identity attribute that defines a specific geographic location. The location identity attribute is associated with the digital information such that the digital information can be accessed only at the specific geographic location. The location identity attribute further includes a location value and a proximity value. The location value corresponds to a location of an intended recipient appliance of the digital information, and may be further defined in terms of latitude, longitude and altitude dimensions. The digital information is encrypted using a geolocking key based at least in part on the location identity attribute. The geolocking key is based on a shape parameter that is determined from the location identity attribute and is included with the encrypted digital information. The shape parameter describes a shape of a geographic area, but does not identify where the geographic area is located. The appliance that receives the encrypted digital information can generate the geolocking key to decrypt the digital information based on the received shape parameter and the appliance location. If the appliance location is not within the proximate area of the location identity attribute, the appliance will be unable to generate the geolocking key to decrypt the digital information.

Cryptographic system and method for geolocking and securing digital information

A method and apparatus for maintaining state between a client (100) and a server( 130) while protecting security and privacy allows the server (130) to monitor and maintain a record of the client's current transaction status via a unique identifier. Generally, the client (100) generates a unique identifier, which it transmits to web applications (134) on remote servers (134) during transactions. The web applications (134) can track a series of continuous and related requests using this identifier to better serve the client (100). Thus, by maintaining state with web applications (134), the clients (100) can take advantage of increased services than otherwise possible operating in a stateless protocol. However, the client (100) is able to periodically change this identifier when the user desires anonymity.
