Abstract: A method for resolving disputes between users in network communications using digital arbitration. The method comprising the steps of agreeing on a contract between the users and choosing a set of arbitrators; appealing to the arbitrators by a first user, if he/she suspects the second user violates the agreement; and giving the information needed to reconstruct a resource of the second user, if a large enough number of arbitrators agree that the second user actually violated the agreement.

Abstract: A method for providing secure connection between vehicles over channels of a wireless communication network, according to which, a first unique pair of digitally signed public key and private key is provided to each vehicle, along with additional vehicle-related data including a visually static collection of attributes of the vehicle. A unique certificate number is generated for each vehicle and monolithic data consisting of the public key, the certificate number and the attributes is signed by a trusted certificate generating authority. Prior to wireless communication between a first vehicle and a second vehicle, a verification step is performed during which the first vehicle sends its unique certificate number to a second vehicle over a communication channel; the second vehicle verifies the authenticity of received unique certificate number of the first vehicle and attributes by a camera that captures attributes which are visible, using image processing means.
