Legal transfer of electronic title document across heterogeneous contexts is a challenging research problem in e-commerce and implies a wider e-commerce transaction scope. This kind of title transfer requires semantic consistency, confidentiality, integrity and legality between transferor and transferee. During the title transfer, cross-context semantic consistency must first be maintained between electronic title documents for legal title transfer while other requirements are considered. To solve the problem, this paper proposes a Cross-Context E-Title (CCET) approach, which satisfies the requirements for title transfer. Based on CCET approach, a CCET prototype is further implemented, on which some experiments are made to test the correctness and performance of the proposed approach.
