Data distribution database and method for data distribution and verification

摘要

A distribution database includes at least one central database, in which data of use-value given by data a releaser and the values of use are stored, and several local databases, each of which is based at a data releaser's site, and which are bisynchronous with the central database. A method for data distribution and verification is provided. The data distribution database provides security and timeliness and requires lower levels of hardware resources. The method for data distribution and verification pertaining to this invention may enhance the data transmission range and use efficiency, and at the same time prevent the interest of the original data releaser against any harm as a result of data retransmission, and also assure shared interest and security for data users.

1. A data distribution database comprising:
at least one central database storing data of use-value and values of use, the data of use-value being released by at least one data releaser, the at least one data releaser delimiting as to whether other data releasers have authority of data retransmission, the at least one data releaser further delimiting as to whether data users have authority of access, the data users delimiting as to whether other data users have authority of sharing; at least one local database based at a data releaser's site, the at least one local database staying bisynchronous with the at least one central database, the at least one local database storing the data of use-value and values of use at least one of distributed and retransmitted by the at least one data releaser, the data releaser delimiting as to whether other data releasers have authority of retransmission, the data releaser further delimiting as to whether data users have authority of access; a delimitation by the at least one data releaser as to whether other data releasers have authority to retransmit the data of use-value released by the at least one data releaser, the delimitation made through at least one of the at least one central database and the at least one local database; a second delimitation by the at least one data releaser as to whether the data users have authority to have access to the use-value data released by the at least one data releaser, the second delimitation made through the at least one of the at least one central database and the at least one local database; a third delimitation by one of the data users through the at least one central database as to whether the other data users have authority to share the data distributed by the data user; a determination of a value of use, the value of use being a product of a use-value of the data of use-value multiplied by a weight of retransmission; and a determination of the retransmission weight, the retransmission weight being a quotient of a retransmitted data releaser's ranking in the at least one central database divided by an original data releaser's ranking in the at least one central database.
