Abstract: The present invention relates to a composition for the differential diagnosis of malignant peripheral nerve sheath tumor (MPNST), a differential diagnosis kit comprising same, a method for providing information required for differential diagnosis of MPNST using same, a method for screening materials for preventing, alleviating, and treating MPNST, and the like. Using the composition capable of detecting the protein marker of the present invention has the effect of making it possible to predict and diagnose whether a malignant tumor has occurred in a patient with neurofibromatosis type 1.

Abstract: A system includes a data module for receiving an original data and a verification fingerprint, and generating a verification data by inserting the verification fingerprint into an embeddable location of the original data. The system also includes an interpretation module for generating data type information of the original data, and deriving an input-enabled location from an embedding location preset list of the original data, wherein the input-enabled location is included in an inactive area of the original data. The system further includes a preset database for storing the embedding location preset list according to the data type information.

Abstract: This application relates to a system for verifying data access and a method thereof. In one aspect, the system includes a service module for receiving a data access request for an original data from a client, and sending a first verification data to the client. The system also includes a verification module for receiving a first data eigenvalue corresponding to the original data from the service module, and generating a first verification fingerprint corresponding to the first data eigenvalue. The system further includes a data module for generating the first verification data by receiving the first verification fingerprint to embed into the original data, and generating a first integrity value by hashing the first verification data. The system further includes a verification database for storing data access information comprising the first data eigenvalue, the first verification fingerprint and the first integrity value in one record identified as the original data.
