Appl. No.:

09/699832

Inventors:

Barry J. Glick - Washington DC, US
Ronald S. Karpf - Gaithersburg MD, US
Mark E. Seiler - Los Angeles CA, US

Assignee:

Geocodex LLC - Encino CA

International Classification:

H04L 9/00

US Classification:

380258, 380264, 705 51, 713163, 713201

Abstract:

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.

Abstract:

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.

International Classification:

H04L 9/00
H04K 1/00

US Classification:

713168, 380 45, 380258

Abstract:

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.

International Classification:

H04K001/00

US Classification:

380/258000

Abstract:

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