TRANSACTION SYSTEM AND METHOD

摘要

The invention relates to financial transaction based on notified changes of ownership of statically held tokens. The tokens may be software entities recording data relating to value, value type, expiry date, excrow period and authentication information linking the token to a purse. The purse is an entity which records the existence of the tokens (the tokens being stored on a token server) and is the interface between a user and the token ownership transfer means. The system further includes purse registers which carry data linking the purse with a particular owner. When a token register receives an instruction to transfer ownership of a token, authentication information is forwarded to the purse register where the user is authenticated. The token register may authenticate matters relating to the token itself. The invention is particularly effective in that it prevents the collection of auditing or profiling data for a particular individual.
