Text Data Integrity Detection Scheme in Outsourced Database Modal
In recent years the database service outsourcing is a database application pattern which emerges recently.In the outsourced database model the data integrity detection is a method which prevent the interior personnel in the outsourcing database provider and the exterior personnel to tamper with the data,and guaranteed that the inquiriers obtain the correct inquiry result.The existing data integrity detection method is aiming at the structured data in the relations database,while as for non-structurization there is not a prototyping solution at present.For perfecting the data integrity detection technology in the outsourced database model,in this work a text data integrity detection scheme based on the digital fingerprint was proposed,this scheme not only detected out the text data integrity,but also the data which had been tampered with can be located exactly;our work also presented two fingerprint management plans,and analyzed the security of the plans;Finally through theoretical analysis and experiment the accuracy and validity of this text data integrity detection scheme has been verifed.
