Abstract: As there is a significant development in potable devices market recently, cloud computing is more commonly implemented. Confidential Batas arc accumulated and stored in cloud servers. To ensure the Batas arc secured, they should be encrypted when being uploaded, which makes efficient searching among them a much complicated task. Traditional searching programmes in encrypted environments are able to find the data only if the keyword is exactly correct,but will fail if spelling errors or format errors occur.These programmes arc hence not suitable for cloud computing. We introduced a high efficiency programme which can deal with even vague keyword searching in the encrypted environment.
