Abstract

The invention provides a dependable preservation and evidence collection system and method for an electronic contract. In the preservation stage, the system obtains identity information and the electronic contract of a contract preservation side and preserves an electronic signature and a timestamp generated in a signature unit with at least one of the identity information of the contract preservation side, the electronic contract and generated running information in a corresponding mode through authentication of the identity information and by generating the electronic signature based on the electronic contract and generating the timestamp based on current dependable time. In the evidence collection stage, the system obtains an evidence request submitted by a proof side and including at least one of the running information, the electronic contract and the identity information, and a dependable electronic contract and contract preservation time can be provided for the proof side as evidence through authentication of the identity information of the proof side and by inquiring the corresponding electronic signature and the timestamp and verifying the corresponding electronic signature and the timestamp respectively.
