A system for communicating anonymized data obtained from vehicles via a computer network, the system comprising: a personalized database in a private zone configured to maintain a plurality of unique identifiers of vehicles associated with respective data; a unidirectional convertor coupled to the personalized database, and located at the private zone, configured to anonymize the unique identifiers by applying a unidirectional conversion, to yield respective anonymized unique identifiers; and a networked server in an anonymized zone separated from the private zone and configured to maintain said respective data associated with the anonymized unique identifiers, wherein the networked server is configured to: receive a request from at least one third party, for a temporary anonymized identifier associated with a vehicle linked to a specific unique identifier; convert the specific unique identifier to a respective specific anonymized unique identifier, using said unidirectional conversion; in a case said anonymized unique identifier exists on the networked server, generate a temporary anonymized identifier by applying a bi-directional conversion to the specified anonymized unique identifier, wherein the bi-directional conversion is specific to said at least one third party; receive a request from said third party for data associated with a vehicle linked to a specific temporary anonymized identifier; convert the specific temporary anonymized identifier into a respective anonymized unique identifier based on the bi-directional conversion; and provide the requested data from the networked server to said third party based on the specific anonymized unique identifier. a personalized database in a private zone configured to maintain a plurality of unique identifiers of vehicles associated with respective data; a unidirectional convertor coupled to the personalized database, and located at the private zone, configured to anonymize the unique identifiers by applying a unidirectional conversion, to yield respective anonymized unique identifiers; and a networked server in an anonymized zone separated from the private zone and configured to maintain said respective data associated with the anonymized unique identifiers, wherein the networked server is configured to: receive a request from at least one third party, for a temporary anonymized identifier associated with a vehicle linked to a specific unique identifier; convert the specific unique identifier to a respective specific anonymized unique identifier, using said unidirectional conversion; in a case said anonymized unique identifier exists on the networked server, generate a temporary anonymized identifier by applying a bi-directional conversion to the specified anonymized unique identifier, wherein the bi-directional conversion is specific to said at least one third party; receive a request from said third party for data associated with a vehicle linked to a specific temporary anonymized identifier; convert the specific temporary anonymized identifier into a respective anonymized unique identifier based on the bi-directional conversion; and provide the requested data from the networked server to said third party based on the specific anonymized unique identifier. receive a request from at least one third party, for a temporary anonymized identifier associated with a vehicle linked to a specific unique identifier; convert the specific unique identifier to a respective specific anonymized unique identifier, using said unidirectional conversion; in a case said anonymized unique identifier exists on the networked server, generate a temporary anonymized identifier by applying a bi-directional conversion to the specified anonymized unique identifier, wherein the bi-directional conversion is specific to said at least one third party; receive a request from said third party for data associated with a vehicle linked to a specific temporary anonymized identifier; convert the specific temporary anonymized identifier into a respective anonymized unique identifier based on the bi-directional conversion; and provide the requested data from the networked server to said third party based on the specific anonymized unique identifier.
